I have the side cover that is over the shift shaft and shift drum gears removed. There was extensive water damage to the shift shaft and the gear sector #3233832. The splines on the shift shaft #3233831 and the gear sector were bad enough that the gear would actually turn on the splines a little bit. I have new parts to replace all the assemblies under the cover. My problems at this point are that I can't seem to get the gear sector #3233839 on the shift drum shaft to come off the shaft. The splines on the shift drum shaft and the sector gear on it don't look as bad as the shift shaft assembly. I am thinking I can just replace the shift shaft and it's related parts and the lockout disc and detent star along with the detent pawl and spring. The manuals for this transmission show alignment marks on the sector gears. The mark on the shift drum gear is at the 9 o'clock position and the shift shaft gear is at the 3 o'clock position. When I turn the shift drum shaft all the way clockwise (reverse) the alignment mark only goes to about the 7 o'clock position. Any thoughts on this? And how would I go about aligning the gears if I can't get the marks together?
