Replacing Clutch Fluid Hose '88 Targa

Replaced the clutch on my '88 Targa recently. Also installed a new slave cylinder. Shifting is not as smooth as it should be. I have bled the slave cylinder multiple times, but shifting still feels as if the clutch is not completely disengaging. Research on the board indicates replacing the clutch fluid hose is next on the list.

Any feedback from the membership? Is this a straight forward process? Suggestions that will make the install easier? Anyone done the replacement recently? Feedback on the results?


Thanks to all for the feedback and suggestions.

The hose is easily replaced but you need to bleed the slave system
On the brake fluid reservoir the tap for the slave is way high on the reservoir so that the brake system doesn’t go dry. Make sure fluid level is high when bleeding.

The hose isn't much of a problem. Did it and the slave on my '88 when it started leaking.
Am wondering if you placed the slave back properly. As it's piston has to push against the release fork, it's a real ***** to get back on in proper alignment.
The thing has to be bled, of course.

I kind of doubt it’s the hose unless there are signs of damage or something. I replaced mine recently just because I was in there but I don’t know of it being problematic. I would be sure the system was well bled and then consider the master cylinder next I guess. How are you bleeding the system?

A dragging clutch will have other symptoms like the car lurching forward ever so slightly when started in gear with the clutch fully depressed or much happier to go into first gear with the engine off than the engine on. Are you seeing any of these? Or jack the back of the car up, start the engine, put the car into first and leave the clutch in. Do the rear wheels want to start turning?

Can you check the alignment of the slave cylinder piston with the engine in the car?

It's been a couple of years since I monkeyed with it, but as I recall, there's an inspection plate that can be removed for viewing (or am I just imagining that?) As I recall, getting the two mounting screws lined up properly with the piston pressing against the cup on the fork provided just enough pressure so I couldn't get the screws started. I know that when I did a couple of times and tightened it down, the piston was missing the cup on the fork so I had to start over. If it went on too easily, I'd be concerned. This has to be done by feel since its at the top of the transaxle and you really can't see what you're doing. See if you can check out that inspection area with a mirror and a flashlight to make sure the piston is seated in the cup.

Just checked the Bentley book.... there is an inspection port that should allow you to see if the piston is properly seated in the cup. Hope you remembered to put a bit of grease on the tip of the piston to help prevent wear.
