FZS1000 Head Bearings
« on: 06 April 2017, 05:12:44 PM »
So while doing the forks i have noticed the head bearings are notchy, quite bad, so need new. Now when i look at the Yamaha parts its about £100.


I have seen the Marksman kit [size=78%]http://shop.marksman-ind.com/yamaha-fz1-2001---05-headrace--steering-kits-23350-p.asp[/size], from what i read the tapered bearings are better was will last longer, if i buy the marksman kit will i need anything else for the job? Better to replace any wee cheap parts while in there is they are perishable.


Seen this topic [/size][size=78%]http://foc-u.co.uk/index.php/topic,7518.0.html[/size] and it has me a bit worried on that the parts will all fit fine? There is a rubber washer mentioned, any idea on part number?

I resently replaced mine when fitting r1 forks & used tapered bearings, think they were made by ntn. They were quite cheap & have proved fine ! Getting the old races out was a job that required patience & a few harsh words along the way though 😀

Allballs tapered bearings when I fit the R1 front end, think they were about £40

tip 18" 1/4 round bar bend one end 30 degrees grind back the inner face but leave a 1/16 flat this will whack out bottom and top set easy before refit feel the inner face till you find the groove i further opened this up with a dremel in case i needed to go back in

I've used this kit on two bikes, everything you need is in the kit. I remember reading that thread and being a bit baffled as to how he'd got it wrong. As for the rubber washer, just re-use the old one. It's only there as a dust seal, if I remember rightly. It's a fiddly job and getting the bottom race off the steering stem is pure butchery. Damn thing will just not move until you're really belting it with the hammer and chisel. The one on my Kawasaki needed only light tap and it pinged off, but Fazers.. jeezuz.


Satisfying when you're done though.

I still have that bike and stick by my comments even though they maybe unpopular.
Parts provided by marksman were a wrong fit.

Thanks guys


I am a total newbie and not a great man on the spanners so this will more than likely be a job for a mechanic but i know that some will ask for a OEM replacement as best option, but i want the options so i can take it to the man.


I did look at the All Ball Bearings ones on Wemoto too, but got Wheel Bearings from Marksman and all was great with fast dispatch and i know a few others use them too.


Will have a think...

Sorry Galahad, I got the wrong end of the stick there. Apologies.


Suppliers do screw up, know. I got a clutch lever a couple of weeks ago, said FZS1000 on the packet and it was not the right part. Completely different pivot on it.
