The new clutch
By: Rob vW Date: September 6, 2021, 3:07 am

In my last post I described what had happened, and the decision
made for the fix.
The new clutch friction plates and springs duly arrived last
week. There was a delay in shipping as in the first instance my
weekly shipment was closed up before the clutch parts could be
added, in the 2nd instance they forgot to put the parts in, so
it was at the 3rd attempt the parts were included and duly
received.
On first glance, everything looked quite normal. The friction
plates are the same thickness as the old ones. However, the new
clutch springs are 50mm long, as opposed to 45mm for the ones
removed, and 35mm for the original specification. This clutch
is never going to slip again!. Ever!
Refitting is just the reverse of removing. However, the new
springs take a bit more compressing and my compression tool of
40mm plastic pipe fittings wasn't suitable. This was mainly
because in the centre of the clutch compression plate is a hole
that is just under 40mm, with chamfered edges. As I applied
pressure by tightening up the nuts a bit at a time, the plastic
was skewing all over the place.
As it happens, I have a special tool for compressing motorcycle
suspension springs. This has a basic cage where the bottom
diameter is about 60mm. This allows the cage to rest directly
onto the flat are of the pressure plate. The pressure applied
was more controllable and eventually, with much care, I was able
to get the locking circlip back into place.
Now to reassembly of the cover and clutch cable & operating
mechanism. This was quite straightforward, but I wanted to get
this done to see haw the clutch felt. It was slightly heavier,
but not greatly so.
The real proof of course is in riding the bike, but first I had
to fill the engine with suitable oil, a 20W50 JASO rated oil
suitable for a wet clutch. And of course the ignition needed to
be reinstalled and set up.
Next stage was to ride the bike. Due to time constraints, I
have only had a couple of hours each evening to work on this, so
the only ride was a brief one up and down the road. I had put
the clutch friction plates in dry as no instructions came with
them. However, having read information elsewhere, it might have
been a good idea to soak them in oil overnight, as the new
clutch is quite fierce. I am sure that this will change as the
plates bed in and soak up oil, but this clutch will not slip
again.
Once I have a chance to really ride the bike again, I will write
up my experiences.

That sounds very encouraging Rob
