Starter 400 vs M

MH · Dec 6, 2018

Trying to bring an old 400 back to life that is missing some pieces/parts. I have located a parts M and I know some things will interchange and some will not. What about the starter? Looks like they are differnt part numbers.

I'm not positive but isn't a 400 starter a 3 bolt and the M a 2 bolt?

Your right Charlie, unless the bell housing has been changed, the 400 came with a 3 bolt starter

Other posters are correct on mounting. But I have installed M nose ends on 400 gas starters so they could be switched the other way. Only problem is some will have holes to clock at the wanted angle and some needs modification for holes and the line up pin. M starter housing may not have mounting holes for the 400 starter switch. 6 volt gas starter from a 300 to the 350 and 400, 450. is the same. 350 and 450 after change to gas 12 volt starters will work if tractor is using 12 volts now. 400 starter pictured with M nose.

400 and SuperM use a 3 (3/8") bolt starter.M uses a 2 (1/2") bolt starter.They are not interchangeable. Then you have the switching differences. 400 uses a electric solenoid with a key or push buttom..M/SuperM use a 'mechanical' switch with a push/pull rod.You may be able to 'canibalize' the M starter to make the 400 useable.

i like your hydraulic reservoir whats it from?

That's the original 400 reservoir, but that's not to big either,but i like his battery box,on the side, i think i might copy that idea !!

From a 400, turned backwards with some extra holes added, Also hole plated off that valve bank mounted to. Pretty tight making a bracket for the rear fuel tank stud. Notice spacers under the front of fuel tank. had to raise it a little to work. Rear of fuel tank is a little higher than the front so hood would sit at the same angle where they joined. Moved radiator to rear of bolster mounting slots and tilted top forward keeping hole in radiator from rubbing steering shaft so hood and grill would meet close to the same angle. Made a power steering bracket to mount a charr lynn and also raise gages up to match holes in the hood. One plus on that was more under hood clearance for the power steering. Also the belly pump housing was gutted and used as a reservoir and engine pump used. Top reservoir gravity flows to bottom one with oil return below oil level in top reservoir. Oil capacity around 5 gallons. Made battery box from 1/8 steel. short battery cables used and a push button starter switch.

M starters have a threaded stud for the battery connection. I don't think they switched to saddle mount switches until the Stage II Super M's.

You can easily connect a solenoid to the M starter.

If you have a good nose cone from the 400, you can cobble something together using the guts and body of the M starter.
