Those Periphery Washers

[rboltz]

Now that the truck is all apart and my excel spread sheet of all the fasteners I removed is finished, I started looking at all the periphery washers used. What is puzzleing is the manual 9 SNL G-741 shows regular washers, or none at all, and not periphery washers. Once again I'm at a loss since I don't have another truck to look at to compare. As an example all my front brush guards had periphery washers under the bolt heads (3/8") but the manual shows none and lists none. Same for the front fenders to the brackets (1/2"). I have a good supply of those washers but wonder what is "correct"?

The principle purpose of int/ext tooth washers is to provide an electrical path between the sheet metal parts of the vehicle. Seems like it was more of a concern in the earlier days of the M37. My sons '53 used them all over. If you decide to use them, make sure they are hardened or they won't do much good.

My 62 has them everywhere.

Tom at Snake River 4x4 carries the square washers if your looking for some Snake River 4X4

A mix of washers would not be incorrect. Washers were mixed and matched over the service lifetime of these trucks as "Joe" used whatever washers were on hand in the motor-pool shop .. That's one reason you may find a mix of washers on these beasts. My own 53 M37 saw service with the Army until 1976.

Same for lots of things on these trucks. Many served for 25 years or more so parts were interchanged with what was current. I saw one M37 at GL in Chambersburg about 8 years ago so it was stuck somewhere in the system before the sale and may have served into the 2000's. I have had more then a few discussions about the proper paint to use also but during my Army time, 1965-1972, all had been repainted 24087 so what is "correct" depends on what era or time frame you want to create.
