"Removed" rear axle and found this - How to reassemble / fix / salvage
Hi All!
So I bought a 1994 250R that "used" to run. I spent last fall sorting out the carbs and getting it into a "running" fashion. I was able to drive it and it shifts and revs good now. So now I am doing cosmetics, gas tank painting, wiring work and painting most of the silver black. So, that leads me removing the entire rear end as it is all silver, including bolts, brackets, etc. Long story short - It took my about an hour to remove the rear axle and this is what I found. Had the beat the hell out of it with a 2.5LB sludge + extensions. What is going on here? I have both of the axle seals (dry and slightly rusted) and then there is another piece that I think is/was a bearing but I only found like 6 ball bearing and then a bunch of twisted metal. The axle looks good but does have a few niks in it at the end of the bearings (or where bearing should be. ) Can anyone point me to a guide on how to fix / reassemble / get new parts? |

That was the bearing of the sprocket.
You will need a new bearing, a new dust seal and a new sprocket base, at least: http://www.ronayers.com/oemparts/a/k...ar-wheel-chain Assembly 42033 in this picture:

You are welcome.
That is the only bearing in the wheel assembly that is not sealed. The last grease the poor thing had was the one Kawa put in 1994. It is possible that parts 42036 and 92027 have been damaged as well.

You may do better to locate a complete used rear wheel and sprocket carrier in good condition. It looks like there is damage to the wheel itself that may cause problems even with a new carrier and spacer.

Found a tire in great shape, a good rim with everything on it (Rotor, sprocket, and axle) and they all look to be in good shape from an 05 250. Only $85 more invested.... Thanks for the quick replies! |

Hi Bill - Thanks for the tips! I am new to "motorcycle rehabbing" so I appreciate the tips on how to avoid this in the future. I will polish the new axle and grease it up real nice. |

A couple things about that tire - look at the production date. It's 4 numbers on an oval on the sidewall like "3607". The first 2 digits are the week of the year (36th week) and the second 2 are they last 2 of the year (2007). Generally 5 years is the lifespan of a cycle tire - no matter how much tread is on it. Rubber dries out and traction degrades with age no matter how much use it has. Some factors like UV , heat, heat cycles, etc will speed-up the process. It's hard to tell from the photo, but it may say "2913", so it would be on the edge. It's in about the 10:00 position in the photo. One other thing on that particular tire - it looks like the sell has used some type of rubber treatment on it to "wet it down". If so, that's a problem. If you decide to use it you will need to clean all of it off well or risk having the rear tire slide out when cornering. |
