Sticking clutch

Postby wigidiwigidiwak » Tue Feb 28, 2012 12:49 pm

Hi all, quick one for you - my clutch is sticking and the lever will not release properly. It's an intermitent problem which is at it's worst in 1st gear. Suspect the cable is fouling or clogged up somewhere. Where should I be looking?

Cheers

Check to see if your clutch arm is returning ok....they can seize up when using during winter with all the crap on the roads....Here's a few pics which shows where the arm is...

Thanks both, will I get away with giving it a good blast while it's all it place, or best to dismantle it?

Try in place (easier with rear wheel off) or only 3 bolts that hold the cover/arm on.Cheers

Hi guys
looks like i might have to free mine off this weekend, but not sure how to get to the pivot where i presume it's sticking.
if i spray WD at the arm, will it get on the clutch or anywhere it shouldn't.
thanks

Mine was stuck where the clutch arm goes into the clutch cover so no amount of spraying would work, I had to take off back wheel the release the clutch cable undo 3 clutch cover housing bolts then remove cover, be careful as a brass piece will fall on the floor do don't lose it. Pull pivot from housing, mine was well stiff, clean & grease up and out back together.
That was what solved mine yours might be a quick fix, I had never removed a clutch cover before and found the job an easy one, if you're going to do it it might be worth getting a new clutch cover o ring for a few quid and you might lose a bit of gearbox oil,
Good luck
And no you can't get anything on the clutch by spraying as it's sealed apart from a vent on top

Ditto, Ian. Although I had a job getting one of the clutch cover bolts undone. When I did, there was a fair amount of crap which needed getting rid of. I also ended up swapping the clutch cable and it's been great since.

As an aside, if you have the cover off its worth replacing the brass plunger and steel plate, as they are a fairly heavy use part. You can get the whole kit from SIP http://www.sip-scootershop.com/en/products/push+rod+kit+clutch+_87090000 for about £6.

I didn't have any grease in mine at all, bit sh1t really, always worth doing cables if there getting on a bit a had a simmy on mine so was easier to remove the exhaust first, 2 birds an all that.
I've been struggling to get back to 1st & 2nd gear though my clutch was playing up, the one Sunday just about to go for a ride, gear cable snapped, replaced both, lovely change now, the inner was a rusty as hell & disintegrated on removal on some bits,
Learning all the time,

Cheers fellas
Will get the bits ordered first, and then have a go at it.
I usually find it's fun tinkering (even with limited knowledge), so should be okay.
I fitted a new clutch cable a few months ago, so that should still be okay.
Thanks

I would replace
'o' rings
brass plunger
pressure plate
clutch cable
Be very careful with the clutch cover bolts, you can easily thread the bolt or the casing, quick rub with a wire brush and spray a little carburettor cleaner to remove as much of the dirt/crap as possible, then spray wd40 around the bolts. When replacing the clutch cover put a bead of grease around the surface that touches the casing, use grease to hold the brass plunger in place
Replacement parts cost around £15 and so not expensive, but i would order two of everything, one set as spares.

It can be big problem on 4T more than 2T. LML wisdom decided on the 4T to leave a nice gap between the lever and the casing, so its a must on every service to pack the gap with heavy grease. Seen a few clutches burnt out due to non-return of the lever so you wanna sort this asap. :ugeek:

Hi, hoping some can help a complete novice (i.e. me) with a related LML clutch problem.

Clutch was really stiff, like not pulling in at all. On closer inspection I could see the clutch arm wasn’t moving at all, so presumed it had clogged up. With the previous guidance I managed to take of the clutch cover, and clean up the spring and arm. When the clutch cover is off it moves freely now (it was a bit clogged).

When I bolt it back on the housing the arm doesn’t move again! Was careful with the brass plug so everything is there, but seemingly no movement (I’m guessing there should be movement!?). I’ve tried googling ‘how does an LML clutch work’ as I’ve really no idea what should be happening.

Has anyone had this or anyone got any helpful ideas?

Hi There,

This will be a clutch fault. The arm compresses the clutch so if it's only causing an issue when the cover is attached, it must be that. Once the clutch cover is off it's only the main nut (probably castellated) to remove to get the clutch out. Word of warning though!! be very careful of the woodruff key which positions the clutch. You don;t want that falling into the casings or you're looking at a complete engine strip!! From there you can either rebuild the clutch, or replace it. Depending on which clutch you have it may be better to just buy a new one.

There are a few specialist tools needed for this job, so if you don't have them it might be more wise to get it into a shop.

Cheers,

Leigh
Another fine tip stole from Mick Maidment!!!!

Thanks Leigh,

Looks like I’ll be buying myself a clutch nut tool & giving it a go!

Much appreciated.
