I don't have the halves it was cut into, and I doubt the guy I bought it from still has them at this point. I was planning on buying one of the stainless steel ones from Vintage Power Wagons...steep price, but guaranteed not to crud up the fuel system, which has been a recurring problem for...

Hah, I was thinking about something like that...maybe filling it with solder!

Bought the carb kit, timing light adapter, new oil filter hoses, a bypass fitting hose, and bypass fitting clamps from Midwest Military. I think I'm going to run the filter housing with the pitting for the shakedown phase, and then swap it out once I'm ready to be driving the M37 on the road...

Well, I got it out: Stupid thing fought me the whole way! I had to file on it with a round file until I could clearly see the peaks of the housing threads, then I was able to dig out just enough of the first thread to get a 1/4 NPT tap started in it. The tap cut the rest out. I couldn't pull...

Wow, it's coming up on a year! Didn't have much time for the M37 over the winter and early spring, but I did finally get some time to wrench on it this week. I made a video for my friend Bill Lewis who'd asked what was going on with it: Last year, I'd discovered my oil pressure gauge wasn't...

There's a guy on the Facebook group who works/worked for Clark and has access to all of the original build sheets, engineering drawings, etc. He used to be on the Yahoo group, before Yahoo shut all of that down.

Turns out my facebook login from college still works! I'm on the Clarktor group now and have posted my data plates, as they are. Figured I'd post them here too: Number on the left is 84629 with a triangular symbol after it. On the right appears to be T-925.

Previous owner said it was very rusty, so I'm planning on getting one of those new stainless tanks. Figure that'll eliminate potential rust issues anyway!

Well nevermind, looks like I *will* be doing a carb rebuild! After sitting with gas in the bowl for a little bit, the float filled up and it floods. Kinda figured that was too good to be true! I looked into the no gauges issue and think I found the problem: Nothing's hooked up! I rescind my...

Yeah that's been my experience with other generic electric fuel pumps. End up flooding out the bowl vent! Any chance someone in central VA wants to swing by and help me dial in the timing? Pretty sure it's way late.

It's 4-7 PSI so I kept the regulator, which is definitely working. With the clear inline filter, I can see when the float closes and stops the fuel from entering the filter.

Threw a new parts counter 12V fuel pump on in place of the original, changed inline fuel filter, runs and drives now. It has a boat fuel tank in the bed, guy I bought it from had the original gas tank but someone had, for whatever reason, cut it in half. Fortunately, the tank straps are still in...

That's awesome! Always thought a 3-53 would swap well in a M37. A guy in town has a Chevrolet 3100 he put a 3-53 in and it's a pretty reasonable engine for something that size. If the flathead blows up, it's definitely getting a diesel.

I have heard that everyone moved to Facebook from the old Yahoo Groups page. I'm not on Facebook though. Might see if my wife minds me using her account.

Yeah on the Clarktor-6 I'm running it gravity feed from the tank, since the tank in that particular model is over the engine. That was my #1 fear there, blowing a pump diaphragm, killing the oil, and spinning a bearing. That Facet pump looks like a good choice, there's a regulator on the...

Miswire confirmed: https://www.youtube.com/shorts/7CQZIaYbLmo The distributor is off by a tooth, I tried to use the tried and true method of sticking my finger over the #1 sparkplug hole while my wife hit the starter, but kept coming up with the rotor between positions. So, I disconnected all...

Yeah, no worries they're definitely staying, I used to wear my WW2 ordinance watch every day, all day, until the concussion from firing a pistol knocked the second hand off! Sure, every decay event that results in a particle or gamma ray passing through you has a nonzero chance of breaking that...

Turns out 1950s army gauges are radioactive: https://www.youtube.com/shorts/fP9saue9w4c

Put batteries in...it's the weirdest thing...all the lights work! Someone must've gone through and redone them. Cranks fine, have spark, no run. Occasional *putt* or carb backfire. Guessing the timing is totally screwed up! The plugs were wired as if the distributor spun counterclockwise and...

I got the engine to fire off earlier this year, previous owner said he hadn't run it in at least 10 years. Needed the usual points cleanup, the starter solenoid was stuck and wouldn't contact (and then stuck in contact!), Bendix gear needed oil as it wouldn't pop out, etc. Here's a short video...
