M37 Restoration (53-41242)

[Wayne Hingley]

Hi Rob. I haven't taken any measurements to confirm frame straightness, but there is no damage evident on the frame or body components to indicate any trauma has ever occurred to the truck, and there are no tire-wear indicators. The frame condition is excellent with no rust. The black frame paint is almost fully intact where bits of the layers of OD and flat green paint have flaked off during my pressure washing. This truck appears to have been in the west for its entire life, where it was not exposed to road salt etc. Ill post a few more frame section photos in the next couple of days.

A few photos of the cross members. Rob: I’m assuming you had trouble with the large boxed-in cross member to the rear of the transfer case. All cross members on this one are solid. They should clean up nicely.

[Rob Crombie]

That does look really solid. The boxed cross member is the only one that warrants repair on my truck. It was utterly rotten where the spring perches are, and had several pounds of dirt/rust inside. So out it will come to be patched up. It has also done a number on the fuel and brake lines where they pass through the cutouts in that crossmember. What are you planning to replace your lines with? I decided to go with some copper/nickel alloy lines as They should outlast steel, and are easy to work with.

[Wayne Hingley]

Yes I can see how that would have an unfortunate impact on your leaf spring mounting brackets. Let me know if you need any measurements or photos as you fabricate the pieces for your repair.

I haven’t made any decisions on material for the replacement brake and fuel lines, but that will be needed soon enough. I did however pick up a few lengths of stainless steel coil armour for the new lines.

Frame ready to go for blasting.

Well, today I learned that the major tire shops won’t even touch the split locking ring wheels like on the M37. I even went to a commercial shop that does heavy duty equipment, highway trucks, farm equipment, etc. They looked at me like I was carrying a bomb in my truck. I was planning to stop at a non-franchised shop on my way home, but ran out of time and decided to give it a try myself.

I did a quick review of Bob’s 2016 thread where he tried out his fancy new tool on some stuck CMP wheels and tires and got a few ideas.

I tried breaking the bead with my pickup on one side of the tire, and tractor bucket on the other... no luck.

That’s when I realized that I would have to cut the tires off. So I copied the method described by Jacques Reed in Bob’s thread. After learning the technique on the first tire, I was able to salvage the flaps on the other 3. I have one more to do tomorrow.
