lower shock bearing

TT-R250M · Super Guru

Hey Toffee,

Brian has a good article on this here- http://www.ttr250.com/TTR_shock_brg.htm

I have also managed to get them out using a size 7 long shank fishing hook (Mustad is my favourite brand smile ). The trick is to get the point of the hook under the edge of the circlip (where it splits) and lift it far enough to get a small screwdriver (or another hook) to pry it out.

You do not need a vice to remove and install the bearing, simply using the right size socket and hammer worked for me. Just be careful not to damage the bearing whilst installing it.

Good luck, you'll need it. wink

I tend to use a very small drill , and drill in under the circlip and that allows me to get a scriber in under the circlip and lift it enough to pop it out with a screw driver (and onto the lawn never to be seen again in some cases)

I have had success recently by using a sharp punch against the middle of the circlip and giving it a clout with a hammer. It breaks the circlip in half or, at the very least, bends one side up to allow it to be removed.

The only problem with the drill method is getting a good seal again unless the hole is filled with Chemical Metal before re-assembly. Its an OK method for the top shock circlip though as that's up out of the way of the mud a bit.

Just my opinion wink

Yep - I think I ought to remove or amend that "show and tell".

I only tried changing the lower shock bearing with the linkage still in place once and its definitely now a bench job!

got to agree with Brain I was mixed up with the top bearing ,

I looked at Brian's thread some time ago and thought that it would be easier to just remove the linkage. That way you can regrease the bearings also.

I have never tried doing it while it is installed and would not recommend it either.
