I have an Allis-Chalmers ACC40 forklift which has some brake issues. The only manuals I've really been able to find are the ones from the Army because they are public domain. Fortunately, they are pretty good. Unfortunately, the part numbers shown in these manuals are all NSN numbers, not Allis-Chalmers part numbers, so I really don't know *exactly* what to get for the wheel cylinders.

The best I've been able to find is the AC4717072, which I think is the correct number. However, I cannot determine to very important points. First, I do not know if the bolt threads and brake line thread is metric or imperial (the brake line thread is really the one that is of most interest to me). Second, I have NO idea of what is on the actual forklift. Are the mounting threads metric or imperial and, more importantly, is the hydraulic line metric or imperial

If anyone can answer this information, that would be fantastic. I want to source the parts for my repairs before I take everything apart.

I can't quite figure out the date this lift was manufactured, but I think it is was probably in the 1970's sometime.
