Thanks for the quick replies, guys. I laughed about blowing out the bell housing with compressed air, gm. Take a look at this picture that shows what the bell housing looks like. It is so full of oil that I don't think I'm blowing out anything in there! I assume all of this oil is from a leaking rear seal in the engine.

All the oil seems to blow back and end up in the bell housing no matter where it leaks from.
Its hard to tell if that's original but.... The Auburn Clutch Company was purchased by Spicer and became Spicer Clutch. Then Eaton purchased it and it became Eaton Clutch. Then they decided to close it down in 2020. Sad, the premier heavy truck clutch in its day. That could be the original or, it could be a rebuilt original. Good tip from gm, never put a new clutch disk on an old flywheel surface. A quick trip to the machine shop for a touch up surface grind is in order to do the job right.
Thanks for the tips. I'll be sure and address the surfacing of the flywheel with the engine rebuilder when I get there. If he isn't planning on doing it, then I'll make sure I take care of it.
Here's a closeup of the flywheel. Is there any reason that I shouldn't try to replace the ring gear on this now? Looks fairly worn to me.

Just for the record, I thought I would show how I rigged up the engine for transport to the rebuilder. It is actually quite stable. I added another strap across the front of the engine that isn't shown in this picture, so the engine should not be able to shift towards the front or the back during transport.

You have a good hold of it there tst! Cinch it down tight and drive careful! Slide it all the way up to the bulkhead just in case something causes a rapid stop. If that thing gets loose it will slide forward with some serious force. You don't want it to have a running start, it could end up inside the cab!
The ring gear on the flywheel is junk. Do not run that gear. Have the shop change out the gear for you when they resurface it. It isn't a difficult thing to do once you have done it a few times. Changing the gear does have its little quirks.
I had one bad spot on my flywheel ring gear and I thought well I'll clean it up and reuse it. I contemplated several times. I even have a new ring gear for it. I put it back together with the old one and the cleaned up spot. Low and behold the motor just loves to stop on that bad spot every time! That forces me into a "technique" for getting the gears to engage to start. To replace it now requires dropping the transmission, pulling the clutch, removing the flywheel and doing it right by replacing the worn gear.

"Take a look at this picture that shows what the bell housing looks like."
When we pulled the truck out of the barn, it smelled like mouse pee. The start of the restoration was to pull out the seats and we sprayed the inside of the cab with Febreze (it takes the stink off just about anything). We let it set for a weekend.
Well, it didn't take the mouse smell away, but we started taking things apart and just endured it. We pulled the doghouse and radiator, then the engine. When we pulled engine, we found that the bell housing was packed solidly (like a bale of straw) with hay and straw and the little devils had made themselves a mouse apartment complex in the bell housing.
Oil and grease would have been a better problem.....
HA! Yes, I agree! Oil and grease would definitely be better. I did take a closer look at the bell housing a few days ago and it doesn't appear to be bad at all. Should clean right up, I think.Originally Posted by LarrBeard
Got my engine delivered to the rebuilder a week ago on 12/27. Said is should take about 8 weeks.
I've started to rebuild the carb in the meantime and have it all taken apart and ready to clean. Any recommendations on a cleaning solution to use for the carb?
There are a few products out there specifically for soaking. I use a large tank ultrasonic, heated and filled with MC-3. They come out like brand new.
