Play on rear disk

[Percy]

Hi,

 

If I hold the rear disk brake there is some sideways and rotational play (about 1mm)

The thing that the disk is bolted onto has movement on the axle,

Is this normal or has something worn?

I rarely use rear brakes and it does not seem to be a problem or getting any worse, just want 2 check

if it is normal,

 

Thanks, Bruce

Thighten your axle nuts.

Hey Percy,

Good to see you're still posting here!

What Meat_Head said just about sums it up.

 

The right hand shoulder of the disc hub should seat hard-up against the shoulder of the axle. The left hand shoulder of the disc hub should seat hard-up against the inner race of the right hand bearing. There should be no movement.

I suggest you get this sorted as the spline between the axle and disc hub will definately start to wear.

 

Correct procedure for tightening the axle nuts:

A few drops of Red Locktite (271) on the threads.

Tighten the inner nut against the sprocket hub and give it a hard nip (55N.m or 40ft-lb)

Spin the axle to make sure the bearings are still spinning free and check for play on the disc hub.

While holding the inner nut with a wrench, tighten the outer nut hard against the inner nut. (190N.m or 140ft-lb)

Draw a line straight across the flats of both nuts.

Hold the outer nut and tighten the inner nut against the outer nut (reverse direction) This should be #$%^ tight! (240N.m or 177ft-lb)

The distance that the lines on the nuts are apart should be no less than 3mm, if less, repeat the previous step.

Hi Guys,

 

Thanks for the feedback. I will get onto it this week and if I have any other questions will drop a line here.

 

JJ - Good to hear from you again. I have left Botswana and am back in Pietermaritzburg. Enjoying riding the Banshee in the Natal Forests!

 

Cheers, Percy

Hey Bruce, good to see you made the move.

I'm quite jealous, missing the outrides a lot. I'm stuck in S.Korea on an engineering project at the moment and haven't ridden since March.

 

Let us know how that axle comes along!

Percy, if you have the stock axle carrier and the brake hub moves there are two possibilities. 1st is that your axle nut may be loose, if not your axle carrier bearings are bad.

 

If you have an after market carrier some tapered brands recommend that you just snug the axle nut, thus you will alwys have a bit of forward and backward movement.
