Thought I'd start a thread to document maint and our exploits with our M38.

A flat fender jeep has been on my father and I's bucket list for years, we've talked about picking one up many many times over the years but for what ever reason have played with other toys and never made it happen. Recently we were discussing this idea yet again and decided to start looking for one. We wanted to find an M38 version, the last of the flat fender jeeps and still had the famous Go Devil Engine. The M38 has the WWII look of the classic flat fender jeep with a lot of great improvements over it's earlier siblings.

With the decision made we posted a Want Ad and started watching all the usual listing spots for a M38. Soon a gentleman contacted me saying he has a M38 that he would sell, a phone call filled in the details. His father Lloyd had restored the M38 and when he passed on his son had inherited the jeep and was looking to clear up space in his garage for his other cars. The Jeep hasn't been driven in quite a few years, being hauled on a trailer to shows and parked in the garage since restoration. After studying the pics and talking to the owner on the phone we decided to hook up the trailer to the Tacoma and head out to see it in person....from our home town in WA state all the way back to Michigan!

Here are just a few of the 40 plus photo's the seller sent me and our first glimpse of the Jeep. Equipped with some nice accessories.

Site limits posts to 4 pics each so I'll break the thread up into multiple posts.

Thanks Mate. I usually host all my pics on SmugMug and post them in my specific thread. An album may work good though with the sites photo limitations.

My father and I have went on a lot of long road trips to snag vehicles over the years, but this one was our longest yet. We traveled the 2250 miles in 2.5 days. The Jeep was exactly what the seller said it was and came with some nice bonuses, a replica Browning M2 & M1919 with Tripod, pintle mount and pedestal. With the deal done we loaded the Jeep on the trailer and headed back west!

We debated on pulling the top off the Jeep for the trip home and folding the windshield down for less wind resistance..... But we were concerned that if we hit rain we didn't want the radio and interior getting soaked with road grime so we decided to try towing with the top on and see how it goes. The top is very tight/secure and tows great, no flapping etc. (We kept an eye on it and it did great all the way home with zero signs of wear. We will probably pick up a small enclosed trailer for future towing).

We made it to Blue Earth Minnesota on Monday afternoon and got a hotel for the night. Up until now we've had clear blue skies but the forecast was showing a major change coming that night. They were warning of extreme thunder storms along with heavy rain, hail and possible tornadoes the following day! The storm system would stretch all the way across South Dakota on Tuesday but would be sunny and clear again on Wed. We decided to hang out at the hotel on Tuesday and let the weather pass, the jeep was secured from the weather and it would give us a little rest from sitting in the truck.

Tuesday and rain. The Jeep came with a fitted waterproof cover, we installed the fitted cover then a tarp over that. We lashed it all down tight with ropes to keep it from flapping/wearing anything, the setup worked great keeping the Jeep nice and dry in the storms heavy rain. We lucked out and didn't get any hail. I'm really glad we didn't push further west as the storm was more severe in SD.

A few misc pics of the radio unit. This unit is set up to transmit on Artillery frequencies. The unit powers up but I have no idea what I'm doing with it LOL. I'll study some manuals on it when I get a chance.

Getting this baby ready to play with...

First up is to clean up both battery boxes. The Jeep came with the correct 2HN military style batteries installed, these are wet cell lead acid batteries and sitting for years hasn't done the battery boxes any favors. Luckily the corrosion wasn't to bad so we set to getting them cleaned up and re-painted.

We will be replacing the 2HN batteries with sealed 51R batts, I've had great luck with sealed batts over the years and the lack of corrosion alone will make the swap worth it. This is a practical swap that doesn't modify the actual Jeep, if someone wanted the correct batts it would be a simple swap back.

The batt compartments as purchased. Sitting in the garage for years didn't do them any favors.

Time to flush and bleed the brakes. The master cylinder is located below the drivers side floor and the cap is vented up to the air filter assembly under the hood (Part of the fording capabilities of the M38). These Jeeps were set up to use DOT5 fluid, the fluid in this one looked clear and not purple (DOT5 is purple) so I flushed and installed DOT4 since it looks like that is whats already in there. All 4 corners were flushed and bleed. Also adusted the free play on the pedal to 1/2" and adjusted the brake pads on all 4 corners.

Front and rear axles were drained and re-filled with fresh fluids. I'll be draining and re-filling the transfer case and transmission with GL4 soon.

Filling the front knuckles. I'm using JD Cornhead grease, this grease is between a grease and an oil...It's thick enough that it doesn't leak out like 80w-90 and thin enough it properly lubricates and circulates unlike regular grease that just sticks to the inside of the knuckle housing.

I heated the grease up with a heat gun a bit and poured it into a oil syringe, the syringe worked great for squirting the grease into the knuckle.

As you fill the knuckle turn the hubs over by hand as you fill. This will get the grease all the way around inside the housing and allow you to completely fill the knuckle to the bottom edge of the threads.

Some great pictures in there. I like the wrench, I have a few of those! A good shot of what the correct consistency knuckle and steering box lube looks like. A good shot of "Corn Head Grease". That Jeep will bring smiles for centuries to come.

Hodakaguy,

Outstanding M38, and an awesome road trip to boot! Being that your rig received a first place award from the MVPA, (think Bloomington Gold for Corvettes) that says a lot about the restoration. It had to be top of the charts to get that kind of award.
Larrbeard will be a long shortly, and he can give you some ideas about the radio set.

He really did a great job, when we purchased it most of the military bits was missing. His son said he enjoyed the hunt of finding all the correct parts. Looking forward to learning more about the radio.

Thanks

Getting a bit more progress in.

Up early and changing out the oil pressure sending unit. The unit was acting weird during the short time we were driving the Jeep, the gauge would randomly quit then show pressure when the engine was off after the key was cycled. It's a good thing I have Go Go Gadget Arms as removing the sending unit is an exercise in dexterity. The new unit was just slightly smaller in diameter so I added a thin piece of neoprene rubber between the sender and bracket for a secure fit.

Drained and re-filled the transmission & transfer case with Redline MT-90. I've found in my older vehicles that MT-90 works great and usually improves shifting. The oil is GL4 and safe for yellow metals. The old oil was nice and clean.

Time to change engine oil. I drained the oil through a clean cloth to see if there were any bits or pieces that shouldn't be there, nothing was caught on the cloth. The oil was defiantly dark and ready to be changed. We ran a magnet through the oil to see if there were any metal fines present...nope, nice and clean. I'll clean the oil filter assy and air cleaner soon.

Fresh oil going back in. In my older vehicles I like to run either Valvoline VR1 or Mobile 15w-50. Both of these oils have higher levels of Zinc for push rod and flat tappet engines. I've always had great luck with these oils so decided to use the VR1 in 10w-30 in the M38. I know oils can be a hot topic....for me these two have always been my go to oils for vintage engines.

WOW! Congratulations on the find. It sounds like it was an interesting trip getting it back home.

You are doing all of the right things with lubricants and the little details that often get overlooked - textbook.

Here are the details on your radio set:

https://www.radiomuseum.org/r/military_receiver_transmitter_rt_6_2.html
https://www.radiomuseum.org/r/military_power_supply_pp_112gr.html

It is a post WWII radio (circa 1949 - 1950) that covers a limited frequency range (27-39 MHz) as an FM voice radio. At the low end it will help interfere with CB radios (but not talk to them as they use AM and single sideband modes of operation). It will operate in the 10-meter amateur band from 28.3 to 29.7 MHz, but an amateur license is required to do so.

Above 30 MHz you are into the military VHF-FM band (30 - 88 MHz, civilian operation is not allowed except for some very specialized applications). It is still serviceable by a moderately skilled technician and most parts are available if you go scrounging for them. The PP-112 power supply used a number of vibrators (no - not that kind of vibrator) and those are probably the least reliable and hardest item to find now.

bmorgil

05-06-2024, 09:57 AM

Wow a very cool radio! I did not realize there were FM signals used in the 40's and 50's. I always thought FM was a late 60's thing. The shear size of the radio in that thing is wild. Larry did it use a "Reed Switch" type inverter to change the DC into AC? Is that what the "Vibrator" was in the power supply? Am I on the right track there? Very interesting history in that Jeep. You can see our evolution of a few things.

Wow! Outstanding Jeep, and you are wasting no time getting it dialed in. Your posting faster than I can read to keep up. That M38 looks like it had an amazing restoration, it's ready for the reenactments.

How much corn head grease and gear oil do the axles take? I need to change fluid in mine.

Looks like you scored a fine example of a Willys Jeep, and you'll have it going down the road perfectly before you know it.

Thanks Mate, we are excited to be it's new care takers and can't wait to get it out to some shows and play around town a bit. I put about 6oz of cornhead grease in each knuckle, not sure what the actually capacity when they are completely empty is.

Looking forward to posting more pics and being an active member of the forum.

More than you really want to know:

The whole rig in your Jeep is a Radio Set AN/VRC-9. It consisted of the the two big boxes; the RT-67/GR and the PP-112 power supply as well as several cables, mounts, speakers, handsets and a long three section whip antenna on an antenna tuner/mounting base. The set also included several nomenclatured canvas bags used as covers and spares bags.

I learned that depending on the type of unit for which the radio set was supporting (infantry, artillery or engineers) different receiver-transmitters covering different frequency bands were used. Your set, the VRC-9, was the artillery version as you mentioned.

It is very unusual to see a complete set with all of the cables, bags, covers and handsets. Enjoy!

Some radio units when presented at rallies/shows have recordings of fire missions, (air strikes or artillery) playing over the speakers in a loop. It adds an extra level of presentation to your display, with little more than an MP3 player tied into the speakers.

I like it! A small Bluetooth battery powered speaker placed right behind the correct speaker would work great. Now to find some recorded artillery radio transmissions to convert to mp3.

A quick Mrs. Google search came up with an hour's worth of combat radio chatter. With further digging, I'm sure you could come up with artillery specific chatter, since there are files for air strikes and battlefield. The rub may be that Korean traffic may be harder to come by, to where the Vietnam era traffic is easier to come up with. For all practical purposes, it really wouldn't matter to what era the recording would be from, unless you were to present your vehicle at a MVPA event for judging. Those guys are pretty picky and would deduct points for incorrect presentation.

Hearing some radio chatter as you walk by an old military jeep would be so cool.

I talked to a gentleman with an MB who made a replica machine gun water cannon. When people walk by and you soak them with water. Or you could go with the real deal, my local armory had a semi auto 50 bmg M2 for sale a year ago, it was only like 6 times what I paid for my Jeep!

gmwillys

05-08-2024, 12:47 AM

That will work!

Ma deuces are probably the coolest round slingers around. We used to have to do remote weapons testing, so we would go over to the armory to sign out a deuce to put on the cradle to bore sight to the commander's screen and setting the cocking mechanism. The small weapons armory was a half mile from the shop, and we would take golf carts to transport. There is nothing like riding around with a Browning resting on the seat of a golf cart. Now we just have an empty receiver and a barrel.

I used to know a guy who had a war jeep with a Browning mounted. They used to be part of the security at the Reno Air Races. It was a good way to get around Stead when the crowd was there.

I know a guy in Tulsa who was making fake propane fired guns to mount in replica airplanes. I never saw one of those mounted but they looked the part on the bench.

Since we just purchased the vehicle we removed the filter assembly from the jeep and disassembled it for a thorough cleaning.

The filter works by pushing oil through the tightly spaced disks. To clean the filter you rotate the handle on top of the filter and it turns the disks and combs the disks to remove any debris that have been caught. The debris falls down into the settling bowl where it can be drained out by removing the plug on the bottom of the bowl or disassembled for a full cleaning.

With the oil filter re-installed we removed the drain plug on the bottom of the filter and cranked the engine over without starting it to ensure we have oil flow/pressure. Oil quickly drained from the filter assembly indicating the oil pump is working like it should be...perfect! The oil looks dirty here as we basically flushed the old oil out of the oil lines in this process.

Received my small rechargeable speaker today for the Jeep. I saved an audio clip of some military artillery radio chatter to an SD card then installed the card in the speaker. Now we can hide the speaker under the radio in the back of the Jeep and when people are walking around it at shows they will hear radio chatter that seems to be coming from the Jeep's radio unit. Pretty cool effect.

Here's a quick video of the speaker in action.

You are truly getting the full experience with that rig Hdk! That is a great toy to have around that's for sure. That baby is pristine. You are doing an excellent job of keeping it perfect. I would expect a lot of people will gather around that one! I am sure the guy's here will agree, that's a concourse restoration there. That video is great.

That "Bluetooth idea" was a great one gmwillys! That is a nice touch for the spectators. I think LarrBeard would agree, I bet those boys back then wish the radio signal transmission and reception was that clear!

It's odd to me that with all the technology that's out there, the radios that we install today are Vietnam era technology with some updated receivers, (probably 90s). There are some digital platforms that tag along, but they are more for the preventing of friendly fire. I suppose they save the satellite band width for the aircraft and the upper echelon.

How in the world did you get them that big and crystal clear??

Thanks Mate. I take all my pics wjth a Samsung Galaxy S23 Ultra phone. These pics are greatly reduced in size to allow them to show up correctly on the forum. I upload my pics to Smugmug then link them to the forum, that way I can have larger pics and it doesn't use up the sites bandwidth. I've gotten in the habit of taking lots of pics when I do a project and sharing them to my build threads, hopefully they will help others in their projects.

A little carb work today.

When we purchased our M38 the Jeep was having a rough time running, blowing black smoke, stumbling and running super rich. It was barely drive-able. The Jeep has been sitting for years at this point so we expected a few make run issues. We changed out the ancient fuel (yellow varnish at this point) with some fresh ethanol free fuel and..... it ran even worse! Sooooo we ordered up a carburetor kit and today set to see what we could find.

The Carb before the disassembly.

Popped the elbow off the carb, the bowl isn't as bad as I thought it might be. Wiping my finger in the bottom of the bowl showed a film of greenish sludge.

The engine starts and runs smoothly now with no smoking. Power/ acceleration is a bit lower than I would expect but I haven't tuned the carb yet, checked timing, valves etc...I'll be doing that soon.
I wish I would have measured the metering rod to verify the kit came with the correct rod for the M38 and not the M38A1, I may end up pulling it back out to double check.

Took a drive around the block with the kiddo and put it back to bed till the weekend.

Removing the old seal, it's screwed onto the bottom of the windshield frame. Removal is easy and quick.

Houston we have a problem. The new seal is shaped a bit different and the holes dont quite line up with the old seal. Hmmmm.....not sure now which seal is correct for the M38. I re-installed the old seal for now until I verify.

Since the weather was so nice we decided to take the Jeep for a quick spin to the fuel station and back. Before we left I did a quick check of the timing....it was way to far advanced. The adjusting nut on the distributer was pretty loose so it probably moved on its own. With the timing set we gave everything a look over and found/tightened several other loose bolts.

And we're off. The timing made a big difference, engine is running a lot better now and has the pep I expected (it was low on pep when I test drove it around the block after the carb rebuild). We decided to run with the windshield down this trip. Fun stuff!

Back at the house and time to get a bit more work done. Our jeep came with a decontamination unit but the previous owner had it just laying loose under the passenger seat...rolling around loose probably isn't the best idea. There are wooden blocks attached to the body just ahead of the tool box lid, these were installed at the factory specifixally to mount the decontamination unit.

Passenger seat removed, you can see the wooden blocks In this Pic.

Here I'm cutting a rubber piece to install between the Decon mount and body.

If you ever want to drill holes in rubber use a piece of tubing in a drill. Unlike a drill bit a piece of tubing leaves a nice clean hole. Use a bit of water as lubricant as you drill the hole.

Super nice Job Hdk! You are not the first to experience the poor fitting windshield seal. I was not able to find a real good fit. I tried a few different suppliers. It seems like there are only two manufactures. None of the ones I received fit well without modifications.

gmwillys

05-18-2024, 04:54 PM

Agreed. The glass guy called me up and asked what vehicle the rubber seal was supposed to fit..... Not even close. Since the 2A glass is within a frame, they used urethane to seal it all up.

gmwillys

05-18-2024, 05:01 PM

Agreed. The cowl to windshield seal leaves a lot to be desired for proper fitment, just like the windshield to glass seal on the 2A.

Cowl seal revisit. I had ordered the replacement cowl seal from Army Jeep Parts and had contacted them after the first test fit. They said the new seal is the correct seal and that our old seal is a cheaper incorrect reproduction. After looking at some pics it does look like the new one is correct and follows the windshield frame correctly.

With new information in hand I set to swapping seals again.

I warmed the seal up in the sun and it allowed the screw holes to line up correctly.

I used a bit of lighter fluid on a paper town to wipe off the white molding residue, leaving a nice black seal.

Very happy with the results. If you need a seal I would recommend this one from. Army Jeep Parts.

Note: With the old seal the latches were almost impossible to close (like the seal was to thick), with the new seal I can snap the latches down by hand now with good tension on the latch...perfect!

Maintenance day. Although the Jeep is running fairly decent it is still starting hard and could be running better. Time to check/verify points, timing, plug gaps and valve lash adjustments.

The M38 is waterproof and equipped with a sealed ignition system, utilizing sealed plug wires and a waterproof distributer.

Distributer opened up and the upper housing held out of the way with a piece of bent wire.

The coil is enclosed inside of the distributer assembly.

Adjusting the points to .020". As found the points were tight. Points were in great cond, same with contact surfaces on the Cap and Rotor.

With the rough timing set it was time to adjust the valves. I bent a piece of tig rod to use as a feeler so I could feel when the piston was at TDC. The bent wire allows you to reach over the exhaust valve and reach the top of the piston. You can also set TDC on cyl #1 and then rotate through the firing order, I like to use the feeler as an extra verification.

Valves were pretty close to spec. A couple exhaust valves were about. 001" - .002" tight, and a couple intake valves were slightly loose. All reset to .016" now.

Cleaning and gapping the plugs. All 4 plugs looked pretty good. Cleaned and ensured gaps were set at .030". This Jeep came with civilian plug adapters already installed which allows you to run cheaper civilian plugs while retaining the waterproof feature of the M38.

The engine started right up and was idling nice and smooth. Now it's time to check timing with the timing light At idle. To do this you unscrew the shielded plug wire on cylinder one and install a non-shielded adapter so the pickup will function correctly on the timing light. After timing is set and distributer is locked down Rev the engine up and watch the timing mark, the mark should advance with increasing engine RPMs. If your mark doesn't change you have an issue with your advance mechanism. All looked good here.
