Need your help with the clutch on my 1950 JD "B" -Serial#270162. This is difficult to describe but here goes!I purchased a new bronze collar (B172R) which pivots on the clutch fork. The new collar has a bronze projection on each end of the collar that accepts the pivot cap screw. The projections are rectangular shaped - maybe 3/16" thick, 3/8" long and 3/8" high. When installed in the operating sleeve of the clutch, the projections are toward the main case. Note that the old collar looks as if it had projections also, but it appears as if they had been removed with a grinder. A friend said he thought the part number did not change but the projections were added later to serve some sort of purpose on a later "B" or "50." He thinks the projections will not be a problem when the clutch and flywheel are adjusted. In any case, when the collar is installed into the proper slot in the operating sleeve, the projections come in contact with the pulley gear when the operating sleeve moves over against the snap ring. I have the pulley on the crank and have installed all of the clutch parts but have not tightened the three adjusting nuts. When I install the clutch fork assembly (with the new collar) and engage the clutch, the projections hit the pulley gear. Since the clutch disks, etc. are not tight, I can easily rotate the pulley. When I do this, I can hear and feel the projections hitting the teeth of the pulley gear. When all is adjusted and the operating sleeve is moved to the engaged position, the projections may not touch the pulley gear teeth. I just don't know. Any thoughts, suggestions, or opinions?? Should I grind the projections off? Or will they not come in contact with the pulley gear after everything is adjusted? I know this is confusing. If it would be better to talk on the phone, give me your phone number and I'll call. Thanks in advance for your help.
