Why is my slave cylinder moving about like this?

Post by conrad »

This has been bugging me for some time. It started way back in March, I think, when we had the clutch done. Don't know if it caused by the mechanic donning his cowboy hat or if the slave cylinder mount has just had it?

You should be able to see in the video that the slave cylinder moves about when the clutch is depressed. As a remedy, so we could actually select a gear, we shoved that wooden block you can see in and secured it with cable ties. It's working as a bodge but it's getting in my nerves. I'd like it to work as it should - and not move about like a street dancer.

Does anyone know what might be wrong/missing/broken?

Many thanks.....

Sorry old boy but you committed the cardinal sin of not telling what exact model you have. (Harry man will not be pleased) When I re-fitted my transmision I found a metal strap left over. I then realised that it was the additional stay which goes back to another part of the casting and stiffens the whole caboosh. My Bentleys doesn't show it but assuming you have the same set up as me if that got left out I guess it would move about like that. Surely you can see if it is metal deflecting or losse/missing bolts.
Sorry to be a bit negative but more info needed.
Cheers

I just read your next post where you do give that info so sorry for that

It should look something like this. The bracket attaches in three places, around the operating lever, towards the front of the gearbox, and the top nearest engine mount. They are a pig to remove, because to remove the bracket you need to release the operating lever, and they are always rusted solid.
Is that a bit of wood there??

Simon.

Ps the bango is facing the wrong way, which I found to my cost after fitting. :oops:

Thanks for the reply Citizen Smith. I can't believe I forgot to mention the model :oops: :oops: .

I think I know the bit you are talking about though. It's a strap like thing that goes from the slave cylinder mount to the bell housing? It's still there.

It looks like the whole thing is flexing but this bit[IMG:1022:767]http://i203.photobucket.com/albums/aa31 ... unt1-1.jpg[/img]
seems to be moving. Is there supposed to be some thing there to stop it moving like it does?

It will rotate around that bit, which is where the operating lever comes out of the gearbox, unless the rear strap, and the top engine mount part of the bracket are in place.

:shock: That looks sooo nice.

It seems to be moving at the point where it's supposed to mount around the operating lever (now I know what that bit is called). The other places where it mounts are all bolted up as they should be.

BTW, it is a bit of wood. When you refer to a bango what are you referring to? :?

It amazing what a 4.99 tin of combicolour satin black can do. :lol:

If it is bolted on the engine mount, and at the back, then it cant move, unless it has rusted or come away at the bracket?? You need to lie underneath, with a torch, and poke around, see what is connected to what.

What does the wood do.??

Just to be sure I'm going down to the van now to have a fresh look but I think all the other bits are connected properly.

Right, was just under the van. When the clutch is operated the bit where it's supposed to mount around the operating lever is definitely the only bit that is not fixed properly. Checked the bracket at the top, it's bolted on securely and the strap bit that goes to the gearbox housing is also present and correct.

Is there supposed to be some sort of grommet or bush that goes onto the shaft that the operating leaver attaches to that keeps the lower part of the mount securely in place?

You know, I'm not sure. John Wayne fitted it when he did the clutch. said it was to stop the slave cylinder moving about too much. He had said something about it being difficult to select any gear without it.

The bracket that holds the clutch slave cylinder should be rock solid, and not move at all. You defo have a problem with that bracket. Is it rusted or snapped, allowing it to move, cause it should not. You will not be getting a very good clutch action like that. A possible cause could be that the clutch operating lever bearings are seized, if you have a heavy clutch pedal then this is what could have caused the loose bracket, as the bracket has bent, rather than operating the clutch.
What is the clutch action like, because with that bracket bending you will not be getting the full clutch movement, and a poor gearchange like John Wayne said.
The best soloution unfortunately is to drop the gearbox, and have a look.

I don't think the bearings are seized. The clutch isn't the lightest in the world but my petite (and slightly feeble) girlfriend manages to drive it comfortably every day. According to the previous owner it as always been the same.

Fortunately I never have any problems selecting gear . It's exactly the same now as it was before the clutch was done. I'm hoping this is another sign that the bearings aren't shot?

I have the van booked in for the flywheel oil seal replacement this week so that might be a good time for the mechanic to take a look. I think it may be a case of getting a new mount and getting him to fit it while he is poking about in that area anyway.

Another £45 quid into the money pit....... :roll:

Sorry mine is built likea brick toilet block and I can't for the life of me see how it can move like that without something obvious wrong with it. Ah well I guess we will know in the fulness of time.

Tell me about it Citizen Smith! I would have thought with movement like that I'd be able to see something.

One thing I have noticed is that the source of the flex is where the horizontal bit bends 90 degrees to go vertical to the left of the slave cylinder.

Maybe the metal has been weakened by the last mechanic bending it to get it out of the way instead of properly removing it when he did the clutch?

Well iirc there is a plastic doo dah, like an insert, that fits in the bracket and holds it around the metal casing of the operating lever. I think it might just be metal. It doesnt positively seat though, but is a good tight fit, it just locates the bracket. If it were not there though it would flex. The bracket should be tight against the gearbox, and you should have no lateral play at all. That could be it. Any Vw breaker will have a pile of these brackets, very common, and not usually required as a spare part.

I would check that area out. You can just about see it on this before photo.
