Yamaha Big Bear, Questions about Rubber boot for Drive shaft.

[Tivy]

My boot on the drive shaft came off this weekend. When I tried to put it back on it appeared to be about 2" too large. Any explanations????

Also when the boot cam off, there was oil in the boot. Is this normal???

Thanks for your help.

jeez...did you get transmission fluid on it or something? That makes rubber expand like crazy. and it must have ripped to come off, correct? maybe it got stretched out when it ripped.

Busglinger, I did not get transmission fluid on the rubber unless that was what was inside the boot when it slipped off. As to know why or how it came off, I have not a clue. The rubber did not crack or bust. I did pressure wash the motor just before riding it the last time.

Since you mentioned the transmission fluid, if the boot is not suppose to have oil inside, then probably the transmission seal has gone bad and cause fluid to leak into the boot and that is how it got oil inside the boot. And possibly it is transmission fluid.

Thanks for your help.

Please, anyone else have any ideas, please advise.

Is there no one else that knows anything about this issues that can help me????????????????

there is no tranny fluid in the bike, just atv motor oil .... what you saw in the boot was old grease that was packed in there ... the same grease for the front/rear axle shafts ... you can probably get a "split" boot to put back on to avoid dismantling the drive-shaft ... whatever route you go, it needs to be sealed
