Hi all, I have new tab washers for the disc bolts but when I torque up the bolts they twist the tab washers any one have any answers thanks steve

you can put a smear of grease under the tab washer & on the nut but if they are after market ones they are only half the thickness of the originals & are not fit for the job. if your not worried about originality fit schnorr washers

Did you have any luck getting round this Steve?

I've got the same issue but haven't figured a way of not twisting the lock washers. They are the same thickness as the ones I removed ( but are not Kawasaki items).

Have you tried with an air impact wrench? The short sharp shocks may 'knock' the bolt round before the tab washer has chance to snag and be drawn round with it, especially wit a drop of synthetic oil under the head. the actual torque, beyond being tight, isn't too critical.

If you wanted to run the wheel round to Woodley I'd have a go with you if you don't have an impact wrench and compressor.

I haven't tried the impact wrench.....I'll give that a go.

Thanks for the offer.

No problem, let us know how you get on.

I seem to have minimised the distortion by taking all the sharp edges from the underside of the bolt heads (new bolts used), and polishing them on my buffing wheel. A bit of oil and gradual tightening and they are tight.

In the Clymer book it states the the torque setting for the disc bolts at 30 foot-pounds which seams high ?

The original Z1 service manual states 140-190 in pounds ( 12 - 16 ft lb ).

Bit of a difference . What's the right figure ?

16 ft lbs maximum
