Hi there. Has anyone out there replaced these for themselves? I normally do all my own work, but gather these can be tough for the home enthusiast. The problem bearing is the main rear triangle pivot behind the crank. Would really appreciate it if anyone can tell me how much tooling I'd need and how much grief they found the job. Also, anyone who can gime me a guide price on what I should expect my LBS to charge appreciated too.
Thanks
The main bearings are the easy ones. The tricky ones are the Horst link bearings. What year is your frame? It should be around £30-40 for a shop to do the full set, not including bearings, of course. Specialized dealers will have the proper tool kit for extracting the Horst bearings.
ive done mine twice, just tap them out with a drift, then press them back in
full set from spesh is about £45
fiddly job but easy to do if you have a smidgen of mechanical talent!
Thanks both! Frame is 2005.
I've done the bearings on a 2006 enduro. Kit from speshdealer was chearper than buying the bearings from a bearing supplier (cheapest bearings they did too).
The main pivot bearings were easy, threaded bar and sockets/washers did it a treat. I didn't feel like trying a drift / hammer approach as they bearing tabs on the main frame are wuite thin and I was worried about snapping them off :-0
The horst link bearings require a small bearing puller. I took it to my lbs with some biscuits 😉
And it's worth buying the fastner kit too for an extra £25. You only get bearings/washers in the bearing kit, and it is useful to have the spare fasters and bolts.
Take a look at [url= http://forums.mtbr.com/showthread.php?t=226577 ]this guide[/url]. I'd recommend using a make-shift press (like those in the guide) to remove the main bearings and upper seatstay bearings, then either drift or fettle a press for the Horst link bearings. You need something that will get in between the two bearings and grab one at a time, or knock one out in-over and the other out out-over (!).
