- - Clutch slave. (http://zr1.net/forum/showthread.php?t=7782)

I'm having the worst time trying to find a slave cylinder. They are obsolete with most parts houses. Napa, Advanced, Auto zone. They show obsolete on there computers. I'm almost tempted to put the original first one back in. I just don't know how to bleed it. There's no way to get ahold of the bleed screw. It looks like its been cut off.

use a 91- later one.. i did on my car..

easier to work what and bleed screw will not break off like the 89-90 models

91-96 is more readily avail.. L98/LT1/LT4/LT5 slaves are all the same

Re: Clutch slave.

yeah Rick...on the later model the bleed screw is on the bottom...if I rememebr correctly from doing mine. Either that or I put it on upside down.

Hello Rick, I have been meaning to say "Howdy" for a while since we are both Houstonian Z owners and share some interests. Just call me Lee.

I had to do my clutch R&R by myself on my '91. OH yea, FUN, FUN. (BTW, thanks for all the pics you posted), but ...even with the later style bleeder screw on top, it was also a pain to get it bleed because of the tight fit and wrench room. I am still not sure I got 100% of the air out. For the first time I can remember, I committed the sin of letting the reservoir run dry. I also read a lot of comments about just having to let the last bit of air work it's way up & out so I just kept working the clutch.

I swore that if I had to do it again, I would try and install one of those spring loaded self bleeder in there if possible.

Another note, you may not have read about yet concerning the badly designed/machined replacements. IIRC, the internal orifice was too small to release the piston and a burr chewed the new o-ring?

Let me know If you need any help neighbor, I am on the NW side of town near 610.

Re: Clutch slave.

I let the reservoir bleed dry at first when I changed mine as well...what a pita. If I was at home I would look under there and see whether or not the bleed screw is on the top or bottom all I know is it was a pita. I still need to figure out why my shifter is rattling.

Good to meet you Lee. After all I've had to do on the car, replacing the slave cylinder is an easy welcome relief. A week after I brought it home I had it up on jack stands replacing both of the exhaust manifolds because the drivers side barfed out chunks of honey comb. And my smart azz nieghbor walks by and says "gee! Your already having to work on it!" I just wanted to throw some of those golf ball size chunks of cat material at her. But I am friends with USAFPILOT on this forum and Rob93ZR1 on CF. We get together every now and then. There are other ZR-1 owners here in town that I havn't met yet. Maybe someday.

Is your shifter buzzing or the whole shifter rattling. My little reverse lock out thinga majig buzzes at certain rpm's and it doesn't matter if you tighten the little set screw. Just shoot a little lithium grease in it and it sets up a nice cushin that gets rid of the buzzing. Just a little redneck enginuity.:mrgreen:

Hi Rick, :wave: I noticed a nice little dent on my passenger side cat while I was doing the pilot bushing job so I hope it is not the 2nd or 3rd or...etc. next problem to worry about.:cry:

I am about to get serious about investigating some serious chug-a-lug symptom mine developed when I nail it. I just figured it would be a secondary vacuum thing, but when it still does it with the key off I am starting to pucker up just thinking about an electrical problem.

Anyway, I read you are a CNC machinist, it seems we share some interests although I don't remember any G-Codes anymore and was just a job shop manual machinist for a short while, you can appreciate how it can get in your DNA for life. I would like to yak:blahblah: with you sometime so if would PM me your phone number and a message of when it would be the best time to catch you with some free time.

Greetings USAFPILOT, I have read plenty of your posts over the years, thanks. I am sure you helped me out with something without knowing it? :worship:call me Lee. :hello:

It seemed about two pumps is all you get? My '91 was on top, with a melted rubber cap from the heat.

Rick, before running enough fluid through it to flush out, it might be a good idea to use teflon tape to seal the threads better and run a piece of clear tubing up and back into the clutch master cylinder or another clear container above the cylinder. Then barely (and I mean just barely) crack the bleeder screw to see if any air after a few pumps. WITH another set of eyes watching the level that is.
