Hoping to tap into the forum's infinite wisdom with regard to a clutch problem on my 147 JTD...

I had my clutch & DMF replaced this week after suddenly being unable to change gear whilst driving (only by rev-matching, with some nasty crunching, did I manage to limp into a side road and wait for a tow to the nearest garage).

Clutch felt much lighter afterwards, and I drove 40 miles back from the garage no problem. Later in the day, after the car had sat on the driveway for a few hours, the problem recurred - clutch won't disengage when the pedal is pressed, and I can't select 1st when the engine is running.

Reading some advice in another thread, I suspected the problem might lie with the slave cylinder - knackered seals letting in air - so I whipped out the battery box and bled the clutch a little. Didn't see any air bubbles but the fluid was quite dirty. The slave seemed to be actuating OK though, giving 6-7cm of travel (at a guess), and there was no sign of any fluid leakage.

After re-assembling, the clutch action improved a little to begin with, but after a few gear changes it was useless again.

I'm wondering:
a) Is the slave cylinder knackered, despite the fact that it seems to be actuating OK?
b) Could the master cylinder be to blame?
c) have I wasted several hundred quid on a clutch replacement for a relatively simple problem with the hydraulics? (147 has done 75k miles on the original clutch)

Would appreciate any advice!

It does sound a wee bit like the slave cylinder is on the way out to me, but from my own experience there would normally be some evidence of it weeping.
Sounds like it really needs to go back to the garage that did the work and for them to resolve the issue.

Hi , I have had issues with hydraulic systems on cars ( I am a vehicle technician ) before replacing any parts try back bleeding clutch , use an oil can cleaned out and then refilled with brake fluid and a length of pipe connecting both bleed nipple and oil can , open up bleed nipple and pump fresh fluid from oil can about 10, 20 pumps . Then lock off bleed nipple and try clutch . Note , you will be filling up brake master as clutch gets its fluid from it . If not works try it a couple of times ( make sure no air gets into joining pipe ) . If ok then clutch goes again then it may be a master cylinder fault . Hope this may help !

Thanks for your replies. I replaced the slave cylinder today but it made no difference. :( Don't have an oil can to try back-bleeding, but thanks for the suggestion.

Given that the hydraulics seem to be OK, with the slave providing plenty of travel, I'm starting to suspect that the replacement clutch wasn't installed correctly. Garage that did the work isn't an Alfa specialist, but I didn't have many options within towing range. I shall be on the phone to them tomorrow...

Back to front?! Really? I wouldn't be surprised to find out that's what's up with mine.

Garage is arranging a low-loader to take it back to them tomorrow. They suggested it might be the gear linkage - I'm thinking not, as side-to-side movement of the stick is fine and it re-centers OK. Plus it's easy to engage gears when the engine isn't running.

Yes, they monumentally focked up.
If it is what's happened to your car then selecting any gear becomes impossible very quickly. When the 'box comes off bits of it (chunks of 'box swarf) will be lying in the bottom of the 'box casing and the clutch will be ever so slightly polished. If that is what happens it's new gearbox time..... depending on how much damage has been done and how angry you get with the garage. You may want to be there when it comes apart......

Good :thumbs:

Hmmmmm...... be interesting to see what happens. Keep us in the loop :cool:

Blimey, let's hope not.

Spoke to the garage earlier - they've got it back and they reckon there's nothing wrong with it :confused: ! I wasn't there to see it, but they say they drove it off the low loader at their end no problem and apparently it's now going into gear fine.

They're going to investigate the gear linkage tomorrow, but I'm still doubtful that's what's at fault.

So, assuming they're not bullsh**ting me, I seem to have an intermittent problem with the clutch. Reckon there's any way the bumpy ride up the motorway on the back of the lorry could have freed up the clutch? Under-lubricated release bearing, maybe?

At a bit of a loss...

It's been fine since - no further issues with the clutch or gearbox. Still a bit clueless as to what the problem was, though, I'm afraid.
