Ordered the parts today!

It depends to a degree on which fuel filter your truck has. The filter on the fire wall has rubber hoses that tend to crack and bleed air. If you install an electric pump back at the tank the leaks will show up when you pump up the lines. The cracked hoses allow air to suck into the fuel pump...

:ditto: While the military used the frame tie down locations, this was largely for ship and rail transit and they also used wheel blocks nailed to the floor with wheel straps. Frame attachments on a trailer can come slack with large bumps and lever boomers can pop open or fall off a chain link...

Sunday evening I drove my M220 home from the Rocky Mountain Air Show. I slowed to 20 on a couple of long steep grades, but for the most part I was above 40 and there were some sections where I managed 55 MPH. The old dual range GMC Hydromatic just has a hard time downshifting soon enough to keep...

The M37 uses bent metal tubes as well to make some bends around the fan blade. ~~ When you get ready to fit the engine/transmission in place, it would be easier if you had the front clip removed or at least the fenders and inner panels out of the way. You should have some extra length (shorter...

Interesting thought!

Since no one has mentioned the increase in units displayed, I will go on record to report that the MVCC went farther than last year. Instead of one low yield Nuke, this year the club displayed two (count them TWO) 25 Megaton Thermonuclear Bombs. These babies are heavy and those little wheels...

Zout, If you need more info than that, let me know. There are other sources as well. ~~~ That kind of help is what this site is all about.

Interesting photos! I notice right off that our new pump impeller is a 5 star pointed lobe while yours is rounded lobe. I wonder if the motor shop did not install a hi volume pump somehow. I have lots to check out before we tear this engine down...

This whole situation is odd indeed. I have done several M37 engine rebuilds including a distributor modification to make a 265 Chrysler Industrial engine fit in an M37 and look correct. I am still trying to figure out how it could have gone together. ~~~ It appears the distributor shaft at the...

After all my talk about offset tangs on the distributor and offset slots on the oil pump, my daughters rebuild sheared the teeth off the oil pump gear about 20 minutes after the start up due to the motor shop installing a civilian oil pump. Oddly enough, the off set tang was able to index into...

I guess we can't malign the old motor shop for all the problem. Just that it would have been theirs to fix if they were still in business. I found the empty Melling oil pump box that they returned to us with the rebuilt engine. It says M37 on it very clearly. The only think I can think is that...

At this point, I am non-plussed! This is the first time I have encountered a distributor that would index (or at least appear to index) into the oil pump when the offset tang system was put against the civilian system. When we dropped the distributor in place we rotated the rotor until it...

This is not current practice with Marine vehicle markings and I don't think it was in the Vietnam period either. I wonder what period saw the M37 bridge weight be painted on the door. I bought my M37 in 1963 which is when I started to pay attention to such things. I don't recall seeing any...

If I had worked that hard on that M43 and made it look that pretty, people would have to pry my cold dead hands off the steering wheel to get it! And I would insist I be buried in it!

When I was checking on the Marine vehicle marking practice, I found there was a period where the Marines required the stencil gaps be hand painted to complete the letters and numbers. I don't know if similar instructions were issued for other branches.

Jollyroger and I gave Ghostdriver a hand with the M43 today. We managed to get some brakes. A little work left there. We got the drive line installed and the clutch linkage back together. Ghostdriver and I had run a mix of gasoline and alcohol through the fuel tank repeatedly until we got clear...

When Ghostdriver took the engine out the generator got pulled and set aside with the mounting bolts slipped back into the generator. No one noticed a misalignment in the fan belt. When she went to reinstall the generator, she found it just did not line up. That and one of the mounting bolts was...
