eddeere Posted March 28, 2015 Share Posted March 28, 2015 A couple of weeks ago I tried to start the model B no spark. The impulse on the mag was broken. Sent it off for repair. I turned the engine over a few times and something did not sound correct. Pulled the governor cover and saw the broken gear. Pulled the steering shaft, hood, engine cover, & fan shaft to get the governor housing off. The fan shaft gear and drive gear have to be changed as a set. I found a good used set in KS. Spent the best part of a day getting these set up with shims and gaskets to get the proper heal and .004 - .007 back lash. The next day getting every thing back together. A lot of work to keep a radiator cool. I restored this tractor 40 years ago and hope to get another 40 years out of it. No clue what caused these to fail. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/39464-1936-jd-b/ Share on other sites More sharing options...

eddeere Posted April 6, 2015 Author Share Posted April 6, 2015 Yes at one point the motor seemed to be locked possibly to this gear broken which is driven off cam gear.
