Roketa MC 54 250B gearbox bearing info By 2stroked (Read 827 times)

Hey y'all, it's me , AGAIN.


This probably isn't the right place for this question, but I figured this section probably sees the most traffic, so what the hey?

Okay, I am looking to disassemble and rebuild the gearbox on my 08 Rockets MC 54 250B with the Linhai 257cc clone.

I am hopefully going to be able to reuse the gears and spline shafts, but I know I will NEED new bearings and seals. I have searched here, and my other three favorite scooter forums, and could not find this info anywhere. Can someone, anyone please tell me what bearings and seals I will need to order. I do not want to have to disassemble everything to see, and then have to leave the scoot apart for a couple weeks, while I wait for parts.

I wouldn't be doing this, but noticed a metallic content in the gear oil when I changed it this morning. I know that a small amount of shavings are to be expected in a gear mesh area, but the sheer amount I found has me worried a bit. That metal can not be good for the bearings.

Any one that can help, I appreciate it.

OUCH!!!!!! I am glad they list the bearing type and seal sizes. 31$ for a five dollar bearing!!!!!! NO WAY. I wonder how many people actually order parts from them??? Saw the stock Kiehin nock off for 432.00$, same carb on fee bay for 50$ or less. Ridiculous.

Thank for the link though. I went there to find the Variator nut size, and only found the Honda clone type parts. They list an entire replacement engine on that page for 1120 bux, but fail to provide a picture. Huhmmm?

Hope those are the correct dimensions, I am going to order a set I hope both of the bearings and seals are the same dimension.

Yea the bearings you can get anywhere for about 8 bucks or less each as long as you have the size. I just put that link up so you could get the size.
