    M37 Barn Find

    Th technical manual TM 9-8030 shows that wire 12 goes from the ignition switch to the center post on the distributor (see pg 180 - at least on my copy). My truck had been converted to a hybrid 12/24 v system. The ignition was 12v and did not have the military distributor. The ignition coil was...

    Original running M37, adding plow rig, question?

    THe M37 Registry forum has a few threads where people posted details of the snow plow mounts. Just search for "plow" from the main forum page.

    Electric M37

    Actually, it was quite common on the home-built electric cars of the 70's. THey generally only used 2 of the gears, however, since the torque band on an electric motor is far wider than on a gas engine.

    I'll be very interested to hear how this works out for you. How did you happen to choose that motor? I assume you be including regenerative braking?

    M37 Hesitation

    Doesn't the stock carb have a separate idle mixture adjustment? If so, is the idle mixture set too lean? I'm not very familiar with these engines, but hesitancy coming up from idle in my chainsaws (once they are warmed up) is almost always from the idle mixture set too lean. I realize that a...

    M37 Barn Find

    OK. I misunderstood when you said "I’ve searched for the relay that came with the truck". You weren't talking about the original truck.

    M37 Barn Find

    I thought the starter on an M37 was activated directly by the foot switch, with no relay involved?

    2" receiver hitch on M37

    I considered one of those, but the ball was far to high off the ground for use with any of my trailers. (I have Michelin 11.00R16 tires on the truck, which accounts for some of the height, but even with stock tires, the pintle hitch is still too high.)

    Rear axle change.

    Is it a stock 230 engine? If so, I hope you are only driving the truck on level ground

    2" receiver hitch on M37

    Which is exactly why I wanted a frame mounted hitch, and chose one with longer surface which bears on the frame to distribute the load well across the frame (lighter rated hitches only bear on the frame for a little over a foot on each side). I did contact the manufacturer about whether is was...

    2" receiver hitch on M37

    As mentioned in my initial post, the whole point of my search was that I did not want to use a receiver which just bolts on to the rear cross member. I need a large drop from the receiver to get my ball to a reasonable height. That makes for a long lever arm putting a twisting moment on the rear...
