Title: 690 headstock bearings
Post by: Altie7deLaan on October 03, 2017, 06:33:07 pm
Hi

Just did a quick WD  search but cannot find anything related to the 690 headstock bearings.
Wallet is super thin and I will have to do the bearings myself.
Anybody can help out with a replacement partno`s and a link on how to maybe?

Thanks

It can be difficult to remove and insert the lower bearing if it is your first time.  Also, removing the lower bearing might/will damage the lip seat that sits below it.  You should get that from a dealer.  The nice thing about 690s (well the early models definitely) is that the stem pulls from the lower triple (for the adjustable offset), so its much easier to knock the bearing off.  When assembling, use heat and cold.

I have the complete bearing and seal kit in stock. R390
I can also take off the bottom bearing off for you - if you bring me the bottom clamp.
Just send me a pm if you are interested.

Thank you all, Appreciate the feedback and help.
I have been using the bike this past weekend through parts of cederberg and tankwa.

This morning I gave the bike a proper scrub. At the same time, I dialed the compression and rebound on the front and rear suspension all the way in, and then set it up again from there.

Took the bike round the block to get it dry and some heat into the drive chain before I lube it again, and it feels as if the notch feeling is gone. What the fudge... Baffled.
Will take it on a proper run over the weekend to confirm.
Perhaps just better to replace the bearings anyway with a bike being 8 years old and 36k on it ja?
