Anybody on this forum had experience of this kind of bearing failure, as described on an overseas forum? Supposedly affects any Sportster engine. Seems like a major and potentially really expensive issue, but I haven't heard anything about it before: "The main output shaft is hollow and carries inside 2 sets of needle roller bearings that in turn support one of the gear cluster shafts. Both the shafts therefore turn at different speed hence the need for the bearings. The problem is that the outer bearing is fitted in such a way that it gets little or no lubricant from the main box. This can result in the bearings failing." | ||

I had an output shaft bearing failure resulting in a blocked rear wheel and a spin, fortunately at low speed. Had to glue in the new bearing with loctite red as the failed one had turned in the case. Having the fifth gear output shaft now in front of me (as a paperweight)I can see that the needle bearings in the shaft are OK and both still oily. | ||

My M2 killed those bearings, and the shaft died as a result. Lack of lube no doubt didn't help anything, but I probably killed mine running the belt to tight. | ||

were these two bearings packed w/ some sort of red grease? While working on the tranny I noticed that these bearings looked RUSTY. I figured since the previous owner removed the pulley cover, water had gotten in there. After wiping down the needles I noticed it looked more red than brown like rust. I repacked them and slapped it all back together. Time will tell. Jeff |
