Rubber Blues on my ES2 clutch

Posted by Grant MacNeill at June 16. 2017

I’m stuck....I’ve got half of rubbers into the clutch spider with makeshift tools.  Managed to press three of them in with a lot of grunt,  C clamps and dish soap as a lubricant.  As each one was pressed in the ability to compress enough to get the remaining ones in diminishes.

I don’t want to risk damage the spider

I can’t find anybody locally who has the magic tool;   the proper wrench and axle shaft tool for compressing them  as pictured in the Norton shop manual.

Does anybody have any suggestions?

I’m thinking of grinding the rubbers down on the belt sander to just a shade oversize.  Then I am sure I can fit them if I do that but perhaps they are meant to be really jammed in there overly tight ?

Are they purposely way oversized or are they meant to be shaved down a bit for a more true fit ?

last time I bought new ones, I asked Les at Russell Motors tot put them in the spider for me.

He vanished for ages and came back with some Anglo Saxon English.  About 15 years back I put some in without much difficulty, and about 10 years ago Les did it without complaint.  They now seem to be made too big (or too stiff) to fit.

When I took it home I found the spider was proud of the cup and nothing would persuade it to re-assemble.

I took it all apart and cut slivers off each until I could get them in. As Skip says - big ones first.

A spare main shaft to put in the vice makes life easier, I didn't have one but made a tool from an old clutch plate and used an old fork stanchion for leverage. I wrapped an old chain around the gearbox sprocket on an old but complete gearbox and clamped it up in the vice so the gearbox wasn't clamped and did as suggested put the big ones in first. It is possible!

thanks Svein

I took your advice and dismantled what I had done and started with the three big ones

2 1/2 beer and some down-east cuss words and I pressed the three little guys in with a c-clamp

So it is do-able without the axle and strap wrench.

I figure it is good for another 65 years ?

Thanks Svein...don't know how I would manage without the NOC

I know it is a bit late now, but I fitted the big ones first then smeared rubber grease on the smaller rubbers and also inside the cavity where they were to go. I then was able to easily slide them in place using the end of a piece of broom handle by simple pushing down. Took only a few minutes.

Definitely Whitworth Grant, ......7/8"dia. about 14"long with an over weight 14 stone bloke pushing down onto each segment. Rubber grease to the rescue again....Wink
