Clattering sound from rear of SV1000

[Mark_h]

Some background....Sv1000, 35k miles, wavy rear disk, newish rear pads, chain and sprocket in good condition, scottoiler + manually oiled chain.

Bike normally sounds and feels fine and is generally well maintained. However, now when I apply the rear brake at low speed I get a major clattering sound from the back. No noise when just rolling and no noticable noise when riding.

Took the rear caliper off, refitted the pads, checked the fixing bolts etc and to be honest it does not seem too bad. The disk is a little worn but so far as I can see the "thicker" outer extremities of the disk do not hit the pads and there is no sign of cracks or raised edges on the wavy bits.

Chain seems fine, tension spot-on and no signs of any stiff links or seized rollers.

Rear sprocket has no sign of damaged teeth

Looking at the front sprocket past the cover I can see nothing odd

Rear wheel has no "play" in it that I can feel and no grittyness from the bearings.

So... Ideally I need it on a powered rolling road (like the MOT test rollers) put on the rear brake and have someone listen to see where it's coming from. Unfortunately I have no immediate access to a rolling road

Sticking on the abba stand, dropping it into gear and running the brake has been inconclusive as on tick-over everything clatters anyway. Will probably repeat but with tickover cranked up to get rid of the low rev clatter you are going to get from chain slap.

Any ideas on where to start?

I have an abba stand, some tools and a modicum of technical capability.

Is there a common cause for this sort of clattering?

Problem is I have no spare bits to swap out so any diagnostic swapping involves buying the bits so want to avoid going down too many wrong, expensive routes.

Thoughts?

Last time I had a similar problem I found the chain was a bit loose and clattering on the exhaust pipe when I braked..

Took the back wheel off today and found the off-side (brake side) bearing is pretty knackered. Surprisingly the drive side bearings are perfect and packed in red grease. The worn one has no sign of grease at all and is totally shot. Then I remembered that the bloke I brought the bike off said there was a spare bearing in the box of bits. So I decided he must have only done one side when he did them last time ( why would you do that).

Anyway, delved into the darker regions of the garage to find it and I'm now confused, the bearing is in a box labeled 09262-32007 which seems to be from the other side where the bearings feel good. I also have a dust seal part 09284-37001 which is from the side I have the problem with.

So there is a chance I have a brand new bearing for the brake side of the rear wheel but in the wrong box! Nothing useful printed on the bearing Any idea how I can tell apart from trying to fit it?

And how hard is it to change the bearing yourself? I have hammers and decent blocks of wood but no pullers, presses or fancy copper-faced hammers. And do I need special red grease or will normal high-temp grease be fit for purpose?

I throw myself to the mercy of the smarter folks.....

Download the correct part of the manual for overhauling the brake, it'll tell you what to do ........ For bearings it was recommended to me to use the 'red' grease eg. "Lithium special" grease (ebay)

Wheel bearings can be removed with the right size socket. Just try and remove as one otherwise it can be a biatch getting the outer race out. You can socket and block of wood the bearing in just make sure it sits where it's suppose to.

It was the off-side wheel bearing.

Just had it changed and all is now silent again.

So if you get a nasty clattering when using the rear brake, take a look at your bearings.

£65 parts and labour all-in. Not too bad.
