Sealed bearing bb for opc

(1/2) > >>

nitrohopper:
Hey guys I am having a small issue with the bb on my fst in respect that it has two sealed 60052rs bearings in it which I replaced when I saw that they were a bit chewed up on the inside (only for my own personal satisfaction ) as they were still very smooth  .now I am having an issue with them going over the collor on drive side and the non drive side just being a tadge to big to go in is there a trick I am missing can anyome help thanks very much  the other thing is that you cant pre asemble as you will not be able to get the crank in ???? Puzzled

Wadz:
id say they were wrong bearings if really tight to go on, all the ones ive had have fitted perfect, take the crank and the old bearing to a bearing company to get correct ones.

pickle:
have you tried the old ones that are still smooth?

Spen69:
Lee, you replaced them because they were chewed up on the INSIDE ??? ???

Mate, you're losing the plot you know..... no-one can see the inside of your BB :2funny:

A decent sealed BB will last years unless you ride it heavy round dirt tracks every day bud - just put the original bearings back in and if you're still twitching, pop the little bearing covers off the new ones and put them onto the old ones :daumenhoch:

See you at MK again bud :coolsmiley:
