Shock absorber - replacing the top bearing with a bush kit

Cheers lads. Looking forward to the circlip bit 😜🛠🍺

Brian,

Any idea which will have a longer service life, the bush kit or the bearing ?

Cheers

Hi Dan

I don't think anyone has had the bush kit fitted long enough to wear one out! The only parts that might wear would be the poly bushing and I am sure Steve would sort you out with a cheap replacement for those if you needed them

Ideal... Just ordered the kit.

It was on speaking to the MOT guy that I established the "play" I noticed was within tolerances for a TTR..still I ordered a full kit from Steve & adopted the "prevention is better than cure" approach

Another excellent "how to" Brian & Steve.

Thank you- straight forward fix...and then onto the lower bushes...then I think it's sand blasting/powdercoating the frame.

Pleased to have helped Rod!

I couldn't resist replacing my own fully functioning rear shock with one of Steve's shiny new ones a few months back. TBH I didn't really notice any difference which I now assume was because my old shock was in perfect working order. Nevertheless it was an easy job and the new shock is nice and shiny wink

Whilst tidying up I came across my old shock so decided to clean it up and check it out.

The only obvious problem was a chunk broken out of one of the top bearing collars which I guess I did when I took it off the bike disbelief

Anyways up, I happened to have one spare collar so set about knocking out the broken one but, you guessed it, I broke a chunk off the good collar in the process!

Those suckers are silly expensive so I decided to fit one of Steve's nifty bearing kits.

I wondered if the instructions on how to remove the circlips (see http://www.ttr250.com/Shock_bearing_fitting_guide.html ) could be a bit OTT straight off without trying the old centre punch trick. So here was my chance to test it out.

Position a sharp centre punch in the middle of the circlip (opposite the open end) and give the punch a sharp blow with a lightish hammer.

Maybe it was my lucky day but, on the second hit, the circlip surrendered and popped out of its groove on both sides ready to lift out with a small plain screwdriver biggrin
