Re: 24 Volt Military Coil Modification
The issue with the stock style coil is that there is no way to retain the coil wire.

Re: 24 Volt Military Coil Modification
John Mc, My truck is 24v with a stock igniter system. I'm looking at swapping in a civilian dizzy with vacuum advance and cheaper wires and plugs. I've been playing around with finding the limits of the compression ratio on these engines and a civilian dizzy is easier to play with when it comes to c...

Re: 24 Volt Military Coil Modification
delta31,
What did you end up doing for a coil?
I just picked up a civilian vacuum advance dizzy I'd like to try out and am looking for coil options.

Re: Does the M37 share the same pioneer tools with the WC's...?
The maul and the axe are not hard to find in the US. I picked up an NOS head for the maul for cheap and purchased a new hickory handle. For the axe I picked up a used one that fit well. For the shovel I purchased a used one and modified (shortened) the handle to fit since all of the stuff I could fi...

Re: Carburetor - Huffing above 45MPH
Rdinatal, It's possible it's the governor. You can test it in lower gears and see if the behavior is reproducible. A search will kick up a bunch of posts on how to adjust the governor if that proves to be the case. I've also seen a low float setting cause issues that were similar to a poorly adjuste...

Re: Another Engine Rebuild...
About that rebuild... Well, we did not get the rebuild done before summer break. I'm disappointed, but it will get done in the Fall. What did happen is I decided that we couldn't do much harm to the engine that got hot and I wanted a running truck. To this end a we completed a valve job on the engin...

Re: 24 Volt Military Coil Modification
An M37 I worked on had a 12v coil and civilian dizzy with a ballast resistor with a 24v system. It worked fine until the resistor's terminal failed due to vibration. You sure didn't want to touch if after it had been running for a while! Unfortunately I don't recall the resistance, but you should be...

Re: Valve Seat Angles
Hi All, This is a timely post since we were playing around with grinding some seats yesterday in what has become the world's slowest engine rebuild! That 20 deg top cut is weird. From what I understand if the angles differences are 15 deg or less the flow will behave as if the seat is a radius cut. ...

Re: Idler arm and bracket slop: Can it be repaired?
In my experience the side to side play in the idler is not that big a deal if the bushing is a good fit on the shaft. It would be nice to have no slop, but if it's not crazy it really doesn't make that much difference. What does make a huge difference is the left front leaf spring bushing & pin....

Re: Another Engine Rebuild...
Hal,
I was out in the boonies and I wounded the previous motor when I took a gamble trying to make it to town when the radiator sprung a leak. I nearly made it!
Eventually it will get fixed...

Re: Another Engine Rebuild...
Elwood, In response to your questions: Are you going to back cut all of the valves or just the intakes? What angle are you using? We'll back cut the intakes and radius the outer edge of the exhausts to try and help low lift flow. As far as angles, nothing fancy, just a typical 3 angle valve job. Por...

Another Engine Rebuild...
After a gamble on road trip lead to damage to the last engine we rebuilt we've embarked on another rebuild at the SLHS Auto Shop. Before I get into the engine stuff I wanted to thank my friends Mark and John for their help on this project and say how helpful the g741 site has been since I started pl...

John Mc,
I like copper washers because I can anneal and re-use them. I put some Loctite PST on the threads too.
