G50 clutch slave replacement

[Adam]

So, I haven't been driving the car much the last 6 months, have had a lot going on (father passed away, I had an ischemic stroke 4 weeks later etc).

Anyway, thought I'd take it for a spin once I was recovered enough to cheer myself up. The clutch pedal was on the floor, I had to pump it up to get things happening. An ominous sign.

After I reversed out of the garage, I noticed a leak on the floor, up under where the pedal assembly would be. So, ordered a clutch master and a slave from our host (the FTE/Valeo set) and put yesterday aside to tackle the job. Jesus...

Now, I have a 4-post hoist, so getting under it isn't a problem.

The master wasn't as bad as I thought. Managed to spring the clutch return spring, but lucked out aligning it blindly by hand and then being extremely careful not to upset it.

However, the slave is a straight PITA. I can't get it off, seems the spaghetti of looped hard lines prevents getting a wrench on the thing and I can't see how to get a socket on it.

I did search and there's not much on the forum about it in terms of advice or tips/tricks, has anyone had success with this job?

Adam,

I just installed a new replacement clutch slave cylinder for my ‘89 Carrera 3.2 Cabriolet last weekend. Just be patience and take your time. Use a 14-mm crow foot flare wrench to get the nut loose for the hydraulic metal line. To get better leverage, I used the flare crow foot wrench with extra long extension and a breaker bar to loosen the stubborn nut. Then remove the two (2) 13-mm nuts that secure the clutch slave cylinder to the transmission housing.

Another approach is to do a partial engine drop and go in from the top-back of the engine bay...

Good luck.

Followed a tip from a different thread and used this brass tubing over the studs to line up the slave cylinder onto the studs against the clutch arm pressure. I think I cut them about 1.5" or search for the post with the photos and instructions.

Worked like a charm.

If I remember correctly removing the transmission support crossmember improves access substantially.

I replaced my clutch slave about 2 years ago. Yes, it's a 120% F!@#$%^ PITA.
I don't recall having a major issue removing the nuts, except small hands helps.

But, on reinstall, I had a small turn-buckle on hand, and it helped to get a few threads to start the nuts. Still a PITA, but helped.


and pic from another post that helped avoid an issue bleeding. (I'm sorry I don't recall where I got it, so can't assign credit. But, it is not my pic). The nipple must be the high point when bleeding.

Bing reverse image search was the only one to find it, Google Lens and others just failed.

I like to have the car just high enough so I can sit on my ass and work. It is a tight squeeze.

Putting a jack stand under the trans cross member, and allowing it to slump 1-2 inches helps.

Thanks, guys. Some good tips, I’ll try them all and let you know how I go.
