Ive read as much as i can on these different cranks and bearing sizes and need a little more insight. So i have a 130202 im building with some mild upgrades and didnt notice till the other day but my crankshaft was to short to accept a clutch, so i got on ebay and purchased a new crankshaft with the longer pto shaft, i also purchased the newer large bearing to go with it part number 555050 and ill be getting the side cover to match it. The crank and bearing came in today and i tried to fit the bearing on the shaft and its tight and will not fit. My question is are they designed this way to be tight if so i have a bearing heater at work to get the bearing on the shaft and does the bearing butt all the way up to the crank gear. Im still learning more and more everyday on these engines and any help will be appreciated.
