Is there a write up on the replacement of the slave cylinder. I assume the motor needs to be dropped a bit to get at it. What does this entail. If you have any comments to make the job easier it would be appreciated.

are u sure it needs a slave or just the acumulator


the slave rerally isnt to bad
1 unhook the battery
2 under body panels off
3 lower transmisison down till it rests on x member
now the fun
un doo the acumulator ball with a band type oil filter wrench
then undo the fitings into the slave ( the bracket is the hardest part)
keep the pentosin off rubber coolant hoses + pentosin = problelms
once the lines are off take out the the 2 15s that hold the slave in
remove the starter
remove the acces hole plug
install new slave sticking your fingers in the acces hole to line up the push rod
reverse procedure
to bleed
fill resivor front and rear
open bleeder start car pump pedal
keep the pentosin off the rubber hoses
close bleeder
your done

The accumulator was replaced within the last year and the symptoms are different from that problem. The system is leaking pentosin out the top of the front reservour. There are no problems with the operation of the clutch when the engine is started as long as there is ample fluid. On occasions in the morning there is no assist pressure until start-up and sometime is works fine. I assume this has to do with how long it sits but I have no data. It is my understanding there is a valve in the slave that goes bad that causes the pressue stored in accumulator to be leaked. I assume this is why the fluild is leaking out the front reservour. I would sure like to see a diagram of the system. Please let me know if you think my thinking is correct here.

I just replaced mine a few days ago. I would check the Renntech Forum for directions. You don't have to drop the motor ot transmission. The slave is on top of the transmission and you can get to it if you put your car on the lift. It is not a hard replacement, it will take a little time. PM me if I can help.

is it leaking or seaping, a lil seapage is normal (not normal but i wouldnt recomend replacment over a lil damp ness) , if the clutch is acting normal i wouldnt worry to much, I dont have a diagram, its really not a bad job to do takes some time, You dont "have" to lower the rear of the tranny (its 6 bolts and makes it sooo much easier )

I would not worry about a seep, it is slow leak. Way more then I can put up with. Thank you for the info guys. So when you lower the tranny do the rear engine motor mounts need to be loosened or do I just tilt it a small amount to make room. Will the linkage through the tunnel be o.k? How far do I lower it? You mention a lift. Will I be able to reach the slave without it? Thank You!

lower the rear of trans with a jack till it rests o nthe cross member, dont touch the rear mounts. the shifter cables should be just fine. Theres no linkage like air cooled cars. probaly better to do on jackstands get better angles that way
have fun

rcatherton

Thanks 99firehawk, that was the info. I needed.

ebaker

Can this job be done on jackstands without a lift?

99firehawk

it could it wouldnt be the best but deffinalty possible

rcatherton

I am picturing a bear-hug around the transmission to get to it. I purchased the slave and it was $275.89 plus $9.81 for a new seal for the accumulator from Sunset.

99firehawk

u need pentosin too probaly 2 cans

rcatherton

Yes, I have it and need to do the job before I need to buy more.

Is one of the Slave Failure modes that fluid is backed up into the front reservoir to the point that it overflows?

I recently noted that on my car but as the dealer had done some warranty work and topped the fluids, I assumed he'd over filled it.

While I found clear evedence of overflow in the front, the fluid level was just a bit over the full/max line and I guessed that when thigs got hot and the fluid expanded, then it overflowed. Either that or he was very sloppy.

I later recheck both front and rear levels and fond both fine. Now I'm monitoring it.

Any input is appreciated please

Michael, I think the diagram of the system would show us the paths the pentosin can travel from the pump side of the circuit to the front. My guess was the assist regulator is built into the slave since the accumulator can be found there as well. I assume the fluid is leaking by a seal in the assist to the peddle circuit allowing the fluid to continually come out the top of the front reservoir. If someone can post a diagram or provide a link that would be appreciated.
