PostPosted: Sat Aug 28, 2021 7:23 pm    Post subject: Dust shield question. Reply with quote

I'm installing some new head race bearings and I have two new dust seals to fit.

After looking at the Haynes manual it doesn't show the FZR1000 model assembly only the FZR750R. On the FZR750R it shows a lower and a upper dust shield.

When I took mine apart it only had the bottom dust shield, so my question is do I fit the top dust shield or not? retard

It should have a dust shield on top of the upper bearing fitted before the first steering stem nut.

I've got the large dust cover that you mention.

The other thing I'm having trouble with is, in the manual it reads the bottom ring nut should have the taper facing up , but in the diagram it is showing a flat surface and the top ring nut shows the taper facing upwards. It's this I'm getting lost with?? retard

Iím not sure what version of the manual you have but mine states that the taper of both ring nuts should face down.

Itís getting a bit confusing Chris. Iím using the Haynes manual. Iím still not sure which way to go with these ring nuts. 🤔

Put the taper down on both, go by the genuine Yamaha manual, the Haynes is wrong.

All done and put back together. It's been a long job and I feel knackered. I've not tried it out yet, but a test flight will be tomorrow. Fingers crossed It all works as it should.

While I was at it I also changed the coolant.

Thanks Creedxup for pointing me in the right direction with the ring nuts.

Iíve been out for a test ride today. I donít know if itís psychological or not, but it feels slightly different with the new bearings fitted than it did with the old ones. Iím thinking were the old bearings worn and was I used to how it handled. Now the new bearings are in and I was travelling on a straight road and every now and again I got the sensation that the front end started to snake gently so to speak. It didnít do it all the time, but it couldíve been the ruts in the road surface. The tread on the front tyre on the right has worn differently due to the camber of the road, so that could be adding to the effect. Tomorrow Iím going to slacken off all the triple clamp bolts, fork top head bolts and the axle nut and push it forward and pull the front brake on and that should make everything line up correctly. Well in theory it should.

Iíll report back later. 🤔👍

Sounds like the head race bearing could be too tight?

With the weight off the wheel you should be able to tap on the end of the handlebar and it should rotate freely to the stop

The handlebars move freely left to right Chris. Iím going to back the bottom ring nut not off very slightly, and see how it goes. 👍
