Head Bearings

Post by tattie »

I will be fitting a set of steering head bearings over the next few weeks, I have the Haynes manual and have sort of read how to do it.
Are there any hints or tips that anybody would recommend for this task, other than getting someone else to do it :lol:

Cheers

Hiya
My advice would be get someone else to remove the bearing race from the steering stem, and put the new one on. I took mine to my local dealer who charged £15 which I thought was O.K. because I could not budge the old one and got really paranoid about Knackering the stem.
Apart from that, the only things I found tricky were putting the new bottom race into the headstock. Took me a while to get it in square (ooer missus).
Oh, and make sure the bike is stable Obviously, as you don,t want it falling over.
Cheers

Ah, it's not too bad a job. Just when removing the race from the head...... yes, you can bang harder! It'll take a good bit to move it.

When fitting the bearing on the stem use something that can give even pressure all round the bearing as it slips on the sleeve.

Get tapered bearings too, the haynes manual shows standard ball bearings, but get the tapered ones.

It might take up to 4 tightens before it completely seats (ie put it all together, go for a drive, undo the yoke and tighten the lock nuts more)

And finally.............. loads of grease!!

If you have never done it before, leave about three hours in total from laying the tools out to putting them back all nice and tidy! :wink:

Tattie, my personal preference would be chip-pan grease, but if you want the bearings to stay in place then I suggest you use 'extra hold' grease. Something like Brillcream or Dax might do the job! :wink: :lol:

I have just changed mine this weekend as it failed its MOT on them. Its not a hard job. Taking apart the only tw@ is removing the bottom part of the lower bearing off the stem. I heated mine up a bit with a blow torch played on just the bearing piece and it came off real easy then. I did cheat by using my mates press to put the new bearing on as its easy to get on if its square to the stem. If your new bearing kit doesnt come with the dust seals, David silver sells them as you will probably shag the bottom one getting the bearing inner off.
