440IC Gas Early Model Transmission Rebuild

Have located most of the main shaft gears for my 440 rebuild.

Question on the M/S Cluster Gear?

The one in the transmission now has a very small space between the two rowes of gear teeth.

My replacement although appearing correct hub to hub length and teeth count, has a larger space between teeth and moves the smaller diameter gear teeth toward the engine about 1/8 of an inch?

I also have the lower mating cluster gear for the M/S gear.

Looks like when laying M\S Cluster gear on top of the old it may still work...any advice or information?

I think that is the gear from another crawler, probably a 40 or early 420. You can put a later gear in an earlier crawler, but not the other way around.

The 440 parts book says I need an M 4195 T Cluster Gear.

I have an M 1688 T Cluster raised letters on back side.
Should I keep looking or try it?

Any ideas where I can find the right one?

thanks,
Scott

Scott,
Your 440 IC early model(440001- 448000 Ser.#) is a 5 speed? If that is correct then yes you need a M4195T first,sec cluster gear.

The M 1688T you have is for a early model 420 (up to ser#100000) firs,sec cluster gear in a 4 speed transmission.

Get Lavoy your serial number, 4 or 5 speed, large or small trany and see what he can find.
