Title: General rear shock question
Post by: Thunderchild on November 04, 2010, 08:29:06 pm

I need to replace the seat, mounting bolt spacer, bearing, sleeve???(or whatever you call it) in the eye of my fox RC150 rear shock.  Like item 14 in the exploded shock diagram found here http://www.motoopartslib.com/2010/04/1960-1969-bmw-r60-2-rear-suspension-parts-schematic/

I have tried pushing it out and tapping with a screw driver, but no luck.  Trying to not damage the eye or shock.   Anyone know any tricks for getting the sleeve out?  Bonus question, what do bike shock manufacturers really call this part?

Thanks
Thunderchild

Well I would call it a bush or may be even a plain bearing and I would press it out in a vice. Use a small socket one side (slightly smaller than said bush)and a larger the other to drift it out when tightening the vice. Works every time  ;D

yep that's exactly what I've done. They're in quite stiff!

Thanks for the socket idea.  But, it didn't work.  This is the 13000 mile shock off of my Oz; I think the seat has welded to the eye.  I have buggered it up a bit trying to get it out.  Have even tried notching the inside with a hacksaw blade and triangle file.  Nothing is budging, so I am going to take it to a machine shop.

Have you tried a penetrating / dismantling lubricant such as Plus Gas?

works wonders in my experience.

Thanks for all the help everyone.  A friend with a lathe made a stepped aluminum insert to push out the sleeve.  Stepped for the inside diameter and enough shoulder to push the sleeve out.  Worked great even on the edge that I had...uh...customized trying to peel out the old sleeve.  The tool worked great putting in the new sleeves too. 

Now to send off my 2010 Marzocchi Air Roco TST for warranty work(leaking oil and air[was new in May 2010]).  I did the first ride this morning on the Mountain Cycle Fury with the coil shock.   It rides so much smoother than the air shock.  I think the Roco is going to go to Ebay land when I get it back.
