Clean the swing arm bearings with petrol and an old toothbrush.

On the opposite side of the swing arm you'll find a plastic bushing instead of the usual needle bearings one finds here on other motos. Not a keen fan of this idea...Yamaha is being a cheap skate in my opinion.

Lower swing arm bearings cleaned and ready for greasing.

[/IMG]
As before,normal steel cage in the bearings.
[IMG]
[/IMG]
Here you can see the needle roller cage in bits...like a silicon cage which has dissolved.
[IMG]
[/IMG]
There'll be 38 needles in each side....(there's 37 here as one is now on the floor)

[/IMG]
Whilst the toothbrush is out clean here also....

Next start on the suspension linkage pivots. Loosen off the bottom shock bolt with a 14mm socket and a 17mm spanner and take out the bolt.
[IMG]
[/IMG]
The bolt is quite corroded. It'll be cleaned with a wire brush and coated in copper grease.
[IMG]
[/IMG]
Next take off centre stand spring....this will become apparent over the next few pics.
[IMG]
[/IMG]
Take off chain roller. An 8mm spanner and a 12mm spanner is required.....note the bolt head opposite the ring spanner.

[/IMG]
Loosen off the frame to 'elbow' bolt.... 19mm and 17mm spanners are required.
[IMG]
[/IMG]
The chain roller has to be taken off to allow the bolt to be extracted. It's too long and will touch the bolt head of the chain roller bolt.
[IMG]
[/IMG]
Lift off the 'elbow' from the moto.
[IMG]
[/IMG]
Loosen off middle 'elbow' bolt with two 17mm spanners....you can do this whilst it's still on the moto if you want. This way I can note,on my moto,what way the riser bones fit.
[IMG]
[/IMG]
The pins are still moist with a layer of grease...so OK so far.
[IMG]
[/IMG]
[IMG]
[/IMG]
Pins cleaned...all OK to refit.
