Thread: clutch question (SERIES 3)

Sounds like the Slave/Master Cylinder thingos
Does it have fluid at the Master Cylinder ?? (Above the steering box)
My bet is it has no fluid if it has no resistance at all

odds on the slave cylinder has jagged its piston seal and shredded it. Check the following.

1. do you have fluid (probabley not)
2. is there evidence of fluid on the clutch pedal or inside the clutch tower (again probabley not)
3. is there any evidence of the flex line down near the slave cylinder rupturing (not likely)
4. remove/check the bell housing drain point for fluid. (should be brake fluid here)

if its not the slave cylinder and youve blown the primary seal on the master cylinder you will have fluid in the resivior but the fluid will just be bypassing the masters piston, If both master piston seals are gone then the fluid will be leaking out of the master cylinder (not all master cylinders have both seals)

in any case on a series a full redo of the hydraulics on the clutch should only take about half a day after you get all the parts.

Thanks for the tips guys, the follow is true.

1. There is very little (but a little bit) of dirty grey almost sandy fluid in the master cylinder (possibly been there for a while without a change).
2. No evidence of fluid on pedal or flex line to slave.

I'm yet to start taking it to pieces as I don't have the parts.

Perhaps its best to get all new bits and freshen it up.

blown slave cylinder, given the condition of the fluid do yourself a favor pull both the maste rand the slave and get them sleved with stainless steel.

someone should know a local supplier for you but any good truck brake parts shop should be able to help out with new units and any good brake shop should know someone who does it.

I sleeved mine in stainless. Cost the same as a new cylinder but at least it won't need doing again. Only the seals possibly.
Do both while you have the system in pieces because bleeding is a pain. Also make sure you put the slave cylinder back with the nipple at the top.
Good luck.

I Just had mine changed under warranty as "Larry" drove me through a red light last week from a standstill. Had my foot on the clutch in first gear at the lights when all of a sudden he jolted forward. At first I thought I was rear ended but as I kept going and by the time I stalled it I was a full car length over the line.

Just as well I was first cab off the rank. The drivers coming from my right were a little confused.

How much does a machining, stainless steel sleeve and seal kit usually cost?

Aaron.

Had mine done recently (Defender)

Machine and stainless sleeve ~ $80
Master cylinder kit.............. ~ $12
Slave cylinder complete ...... ~ $40

And a couple of hours of my time.
