2008 GSA clutch change progress - pressure plate crazing query

[andeebee]

Made slow progress with the slipping clutch investigation, however managed to split the bike this afternoon -

Output shaft spline shot for those who are interested in such things - dry as a bone...

Normal surface rust greeted me. No sign of oil contamination (background patches are from the wd40 I used to get the bike apart)

Finally get the friction disc off and looks like its had its day. Measures just under 4mm... Pictured next to new one.

My question is regarding the pressure plate. There appears to be some crazing on the plate at 11 oclock and 3 oclock in the next image. Is this plate now buggered? Could it be saved? Is it OK?

The rust is fairly normal,
Check the splines for wear.
If the springs on the pressure plate look good it will probably be ok.
Take a sanding wheel to it and get rid of the sheen.
I have a pressure plate out of a 05 in the workshop you you can have FOC + postage if it is better than yours.

IMHO crazing isn't good and for a proper job the PP would be better if it was renewed.

That horrified me seeing that! My clutch is slipping when I roll it on at speed. I bulk as I know I will inevitably splitting my bike in two like this soon!

 

[Mistacat]

I am inclined to bite the bullet and replace the whole Assembly.
Also found the heavy duty oil proof plates to last over twice as long as a standard plates when used on an instructors bikes.( a lot of town riding).

 

[andeebee]

Thanks for offer of replacement Pat, although Motorworx site suggests pre 04/06 plates are different so I would require entire assembly and a different pushrod?

FATTMAT My clutch started like that and I managed to commute on it for the entire year until I could no longer overtake cars, which frustrated the hell out of me. It wasnt slipping all the time, but prolonging the change has probably contributed to the crazing/wear that is now evident IMO.

Slowly discovering why this bike is called an Adventure...

Bit the bullet and ordered new complete clutch from Motorworks. I dont want to be stripping this bike down again to fix any other clutch problems.
All seals look good - whats the consensus - leave alone or swap out while its out?

IMO. while you are going to all this trouble You may as well swap them then it's job done

 

[AberdeenAngus]

Swap the seals. Piece of piss while you're at this stage.

 

[Popell]

+1
It was the seals that did for my clutch - plate contamination, otherwise great condition.

 

[Pukmeister]

My 2008 clutch pressure plate looked just like yours. I replaced the lot despite no oil contamination, minimal wear etc. The new clutch still slips when I give it the beans in top, that's a good way to waste the best part of £400.

I think it's very clear where you are going wrong. You appear to be using the Star Wars manual instead of the Haynes workshop manual.

You should have noticed when the hyperdrive would not fit next to the crash bar.

Change the crank and gearbox seals. If the box rattled in neutral it's also likely to need some internal work.

On mine there is no way to separate the wiring loom so rear end removal needs more work to strip off the seat base bodywork to access the wiring.

The rear frame is intended to unbolt at the bottom engine mounts and hinge up at the top mounts. Shock absorber to bolt and throttle body intake rubbers have to be disconnected.

£400 for clutch parts. A Fiat Panda 100HP clutch kit including release bearing costs £60. The Fiat 1746 Punto HGT (130bhp) is only £90.

Some of the sections said 'apply some force...'

 

[patzx12]

I would have just dropped in a clutch plate.

 

[Bendy toy]

Me too. My gearbox is noisy in neutral so will need some work - or a low miles replacement. Money saved by keeping the pressure plate pays for the new box.

I have to tackle this job on my 09 adventure. Had to replace my alternator at the weekend after it decided to burst. Not looking forward to splitting bike in two.
