I was looking over the teeth on the governor that mates with camshaft gear, and I noticed a few of the teeth were broke. I decided to take a look at the camshaft gear, so I slowly turned hand crank, and found the same , two teeth broke on camshaft gear. I wanted to see the movement of the camshaft gear, so I cranked hand starter faster, and it turns out of round and almost hits timing cover. So , now what???? repairable? or is she scrap? looking for advice. also , what would cause this?, the weights broke on the governor and the engine went to high rpm's, I shut the tractor off right away. thanks.

If the pins are at all loose then it is again cheap insurance to replace the weights and pins. I did this on the 226 engine of my D grader and I now feel a lot more comfortable if my engine over revs a little going down a hill knowing that the governor is not going to self destruct.   [Reply]   [No Email]

Texas Denny has you covered on that. Most all B's had magnetos. Some very late ones had factory dist. Does your B have the very popular aftermarket dist. drive bolt on assy.?-which bolts right on in place of the mag. If so then your gov. gear assy. is common to most B's and C's.(It has the slot for the drive tangs on the mag.) The factory dist. drive uses a different gov. gear assy. Instead of the slot it has a shaft going to the rear with the gear on it to run the dist. It is the same on a CA. You can take a dist. drive/gov. gear off a D series and put in on an older tractor, but if it has a tach. drive built in, then there's no provision to hang the coil.   [Reply]   [Send Email]

There is no provisions for a tach on mine. and the coil is mounted on the distributor.   [Reply]   [No Email]

It is probably the gears that are broken and camshaft is ok. Pull the radiator and the steering pedestal. May need the water pump and a few other things before getting this cover off. Once off, you can rig up a dial indicator to see if the camshaft is ok.   [Reply]   [Send Email]

The dial indicator would have a magnetic base that would attach to a flat spot on the block. Adjustable arms would allow the indicator stylus to rest on the shaft. As the shaft is turned, the indicator would give run-out. If the head is removed and all the lifters are up enough to avoid touching the cam, a bent camshaft would likely bind as it turns. This is a course test, particularily if the bearings are a bit loose but it is a good first test. If it binds a lot, the cam is bent. The gear, if it is undamaged, could have the face measured with a dial indicator and provide several times the accuracy for measuring run-out over measuring the shaft directly. I'm afraid these are the only methods I can think of. Maybe someone else on the board will have an idea. These dial indicator setups can be purchased at companies like Enco or Grizzley for less than $50 (at least that's what they cost when I got mine).   [Reply]   [No Email]
