My old cletrack has a wd45 engine and has been a outstanding machine to plow snow with. However it has been very hard to get into forward and reverse gear. It just wanted to grind (not good) . Has been like this for some time. I tore into it this weekend expecting to find Bad pilot bearing. After getting tore down I have found one of the pressure plate finger bolts with jam nut had came loose. I m assuming that this would let pressure plate put just slight pressure on clutch causing shaft to turn not allowing it to slip into gear. I will be replacing pressure plate, clutch, pilot bearing and throw out bearing soon. How do I adjust the fingers on-pressure plate? And how can I make sure this won t happen again. My bellhousing does not have any kind of inspection hole of any kind.
