My name is Nuno. I live in Porto city, Portugal, Europe.
I have just restored a Willys MB, from 1944.
The restoration of classic vehicles is my main hobby, and I consider the Willys MB and Ford GPW, in addition to their historical value, simply extraordinary.
In this forum I would like to clarify doubts that have been arising during the restoration of my MB.
Thank you all.
Regards,
Nuno
Welcome Nuno!
Very well done restoration! I especially like your drive line test stand. Please ask away, we will be happy to help!
Thank You so much.
I have just posted a question on the forum about 2 different Willys MB brake drums, about which, to date, no one has yet clarified.
All the best,
Nuno
That is a jewel, congratulations on a great restoration.
Great looking Willy's!
Tank You ��
Thank You ��
A. I agree that the drive line test setup was a really professional setup. At a quick look I thought you had the engine on a dynamometer!
B. Very nice Jeep. Thank you.
This looks like a question for GMWillys, the wisest of wizards ...
NMelo, I love the test stand! Perfect man. Nice restoration project there.
NMelo,
All the MB and GPW Military jeeps came with the same part number of the 9" by 1 3/4" brake drums for the wheels. There was an upgrade that came about with the '46 Willys Wagon and pick up trucks where it was deemed needed for the heavier Jeeps. The new drums were 11" by 2" drums. the 11" drums could be easily retrofitted to the earlier jeeps by just installing the brake assemblies. This gave the benefit of adding slight bit more stopping power without having to change out any other components.

The parking brake does have a couple of options depending on the year of production. the '41 - '43 had a band style of brake material that expanded to contact the drum on the rear of the transfer case. The '43 - '51 parking brake was a simpler, brake shoe and actuator set up much like the wheel brakes.

Thank You. Lets see if I will finally have an explanation about the brake drums doubts that I put on the technical issues, here on the forum.Quote:

Dear gmWillys,
Thank you very much for this useful explanation. However, I think it does not explain the difference that is at stake in the two brake drums I refer to.
As you can see in the diagram attached now to better show this difference, the braking surface marked by the letter "A" is in both cases equal.
The difference is in the location of the central shaft, marked by the letter "B", which in one case is more inland than in the other.
That is why when placed, the distance between each brake drum and the brake plate is different, with greater distance in one case, than in the other.
On the other hand, in the two photographs it is possible to perceive the different distance between the brake drums and the brake plates, because of the positioning of the central shafts.
