[WayneUK]

I've found the seals, I emailed them about the collar has it said ETA so waiting to hear from them to see how long it would take.

Do a search on ebay for the part number -

• No.17, Collar, (90387-102R4) - https://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=90387-102R4&_sacat=0
  
• No.24, seal, (93109-17071) - https://www.ebay.co.uk/sch/i.html?_from=...0387-102R4

Mate, can you find these?

Wemoto.com are showing the seals in stock, £5.62 + £3.00 postage to the UK.  Looks like the collar is out of stock though.

Let me call Fowlers just now..

Mate I'm referring to the parts on Wemoto?


Fowlers will get any Yam part if it's still made and carried as stock in 24 hrs from the EU distribution dept in Holland, if they don't have it.

So ebay is lying. Fowlers don't have any stock as Wayne found, but Yamaha Uk do. Lead time from purchase over the phone to arriving through your letter box atm is 7-10 days.

Looks like Yamaha have changed how the do business, Fowlers used to be one of the main spares importers they supplied most others.  Oh well you learn something every day

[WayneUK]

I've managed to get everything off, the collar doesn't look to bad just a good clean?

Gnasher will correct me -

• if you hold a flat edge to the collar and cant see any daylight between the collar and the edge then your golden. I would also say if you can feel anything with your fingers nails that also a good sign.
  
• Also those bolts while a bit corroded also look fine - but do the above check on them.
  

If they are good, they should clean-up with some Autosol.

[WayneUK]

I have a suspension linkage coming, should be here on Friday, maybe this will come with some collars,So I'm going to clean everything up while the swing arm is off, also have some new bearings for the pivot shaft which I might put on too.

[Gnasher]

You need to put a micrometer on the pin and measure it in several places, as they wear with flat spots and eccentrically.  The darken area is wear (lack of grease) often the needles wear more then the pin, looking at the movement and the pin I'd say the bearing is shot.  Quick way and only as a guide is clean out the bearing with brake cleaner, once all the old grease is out shake the bearing if it rattles it's shot.

Check the seals, if they're hard/brittle replace them or your new bearing will fail in short order.

• Didn't think to think of that, makes sense. But I would think the straight-edge method would also show this..? if you rotated the collar as you checked..?
  
• Learn something everyday.

It would, but to a point, measuring is the correct way.

I'm just on with cleaning the swing arm, which seems harder than taking it off the bike  :lol and noticed some black tape is that there for a reason?

[Fazian]

Pull the tape off and have a look, probably covering a bit of surface rust.

[b1k3rdude]

Im fairly sure Ive seen the same tape on on one of my FZS1000 swingarms. No idea what its for, I might be covering a small drain hole, so your best just leaving it alone.

[WayneUK]

Is this normal for movement of the bolt through the collar?
