Hi all,

Swing arm pivot bearings are getting a bit creaky, how much of a job are they to replace?

Cheers

Matt W did a nice pictorial of that and the paralever ones earlier on this year, try a search.

MattW is back from a weekend away and noticed this :)

Not a bad job (especially the second time in two weeks :rolleyes: ) - I used a Clymer manual and did it more or less 'by the book'. Might be too late, but a couple of points worth noting:

Removing the old pivots - you'll need plenty of heat - don't be tempted to crank on them - you can destroy the threads in the swingarm. When they are hot enough the loctite will soften and they'll undo - you may need to apply more heat half way through undoing them.

I did use a low range torque wrench to set the preload on the adjustable pivot (7Nm from memory - bought the wrench just for this job). Others will say do it by feel, but I went for the security blanket of a wrench. When you are tightening the adjustable pivot, work the FD housing up and down as you tighten to bed the bearing properly. It's worth slightly over torquing it, backing off and then setting the final torque.

I would recommend that you don't use the specified green loctite (270?) when you refit the pivots - it sets like concrete and you'll regret it if you ever have to do them again. I used normal blue loctite (243) and did the adjustable pivot in two stages to avoid the need for the special tool (locitited the adjuster, set the torque, waited overnight for the threadlock to set and then fitted and torqued the locknut using pencil witness marks to make sure nothing moved). Some people never use loctite for this job but I was uncertain about the adjustable pivot moving when I tightened the locknut so I did - wus :D
 
Thanks Matt,

I've not started on the job yet, ordering the new bearings this week.

No worries - good luck :thumb2

Just thought of something else - all the various how-to's mention this but it's worth re-stating:

Be prepared to spend time cleaning the old loctite from the swing arm and pivot pinion threads - it's a faffy job but you've got to get all the old stuff out in order to set the low torque on the adjustable pinion. Acetone (solvent based nail varnish remover) and wooden picks will be your friends. I think Cookie did a good pictorial on this - worth searching it out.
