Clutch fettling

Posted by Richard Purdie <rpurdie-at-rpsys.net> on 30 June 2015 | 0 Comments

Inspired by Mikes tales of oil changing, I thought I'd mention the
conclusion to the clutch dilemma.

I bought a new clutch basket, somewhat hampered by people advertising
things they didn't have stock of.

It arrived and I read the instructions "press out the centre of the
original clutch basket", then realised you need a hydraulic press for
this. Being determined to marshal this weekend, one was duly obtained
(I've a crankshaft to rebuild too sometime etc.).

This turned out to be a Haynes book of lies style instruction.
Attempting to press out the centre, the pressure went to several tons,
then the aluminium basket shattered with a noise that leaves me shaking
thinking about it even now. Except around the boss of course which
stayed intact. There wasn't enough left to deploy the press onto so
saws, dremel and then a drift and hammer were ultimately deployed
successfully. Drilling and punching out the rivets worked out in a more
straight forward way to get the backplate/ring gear off.

Pressing the boss into the new basket was also straightforward, even if
my press gauge appears to give half the pressures in the instructions
(or I've messed up).

I'd previously put the carb in an ultrasonic cleaner and tried to blow
the dents out the exhaust expansion pipe, with some but not complete
success as the dents were all on welded seams. Those parts were duly
refitted along with the new Rekluse clutch.

Standing with the oil filled reassambled bike I realised a clutch plate
was left over. I was pretty sure this was ok but ended up taking the
cover off again to check. You can do this with the bike on its side
without draining the oil but afterwards there was thick black treacle
style oil coming from somewhere, turned out to be the powervalves drain
pipe which I'm less worried about.

Upon reassambly I even remembered to unblock the gearbox oil breather
pipe since the gearbox was at vacuum when I disassembled it
(incidentally connecting an airline to clear such a pipe makes a right
mess).

The automatic clutch is just plain weird but I think I'll grow to like
it, it also proved the idle on the bike was simply too low. It all seems
to roughly work, I've followed in the "break in" procedure in the
manual, much to the undoubted delight of the neighbours. I've therefore
committed to marshal the enduro at the weekend so we'll see what that
brings.

For some reason I read a post about Patrick's first race at Cadwell a
couple of days ago and it brought back memories of my first trackday and
how nervous I was. Its a good job Ixion-at-Cadwell is two day as otherwise
I suspect I'd never have taken a bike on a track again. I got over those
nerves, I also got over the nerves of marshalling in general (e.g
Kielder rallies), I'm still apprehensive about the enduro though. Going
outside your comfort zone is probably good once in a while...

Of course the hydraulic press turned out to be incontinent and there was
oil all over the place this morning. I've obtained a replacement pump so
am hoping that sorts that. Nothing ever seems quite 100%
straightforward.

Cheers,

Richard

It's bound to end in tears

Posted by mike <mylovelyhorse-at-gmail.com> on 30 June 2015 | 0 Comments

On the way into work this morning I purchased an oil filter, 4 litres of
15W40 and an air filter for the GS. This evening when I got home from work
the bike got its 42,000 mile service only 450 miles or so late.

The air filter was remarkably easy to change - earlier model years
requiring a fair enough of bodywork removing, but for mine it's one central
panel off (6 bolts) and then 4 retaining screws to reveal the filter. It
was rather cleaner looking than I expected so I kept it for just in case.

The oil drain is on the side of the engine so after I'd removed the belly
pan (2 bolts and 4 nuts) I drained the engine. The oil filter was a little
harder to get off as the belly pan mounting point stopped me getting a
filter remover (like a huge socket) on it. I resorted to putting a
screwdriver through it and twisting it off that way.

At roughly this point the Weather decided to intervene and there was a
terribly bright flash accompanied by an instant roll of thunder that made
both Susie and I jump out of our skins. I thought it was going to tip it
down but nothing.

I don't know if it's still received wisdom but I have always filled a new
oil filter with fresh oil and also wiped a smear round the rubber seal. New
copper o-ring on the sump plug and in that went, then oil filter on and
done up hand tight. Proper hand tight, mind.

I filled the engine until the dipstick registered middle and ran the
engine. No leaks! Belly pan back on, clear up the gas rage and top up the
oil level with another 1/2 litre or so and the dipstick now read max.

I confess I ran it again, just in case. Still no leaks :)

<Hoddy> it'll probably catch fire or something on the way to the Chunnel
</Hoddy>

Still, I enjoyed my spot of light mechanical activity :)

The old trick of tying the brake lever back to squash the bubbles.
That has never worked....

3 hours 50 minutes to go 5 miles with a temperature of 88F.
You'd think those blue-based bastards would have something better to do,
like playing war games.

I regularly use switch cleaner when I can't find brake cleaner, use it on
the brakes, chainset and most other moving parts after hosing down the MTB
then liberally apply gt85. I usually gear the rear suspension about every
five rides and then oil the chainset again before riding.

I tend to blow it through with the hose then the aforementioned switch
cleaner until things appear to be clean and then again with the gt85.

I do seem to be repairing a spate of bottom brackets from friends bikes at
the moment, usually the ones who don't clean them :/

Silly question: it's not a shimano brake is it? They don't use DOT
fluid...They use LHM or expensive shimano fluid if you prefer
