4KQ clutch slave cylinder replacement tips...

[ed armstrong]

Hi,
As Dennis mentions, the critical part is to drive out
the thin "expansion pin", what I would call a roll pin
that secures the clutch slave cylinder to the top of
the transmission housing. The right sized drift is
critical. I believe it is 3/16" . If you are 1/16" to
big or small, it will not work...trust me, I bought
and tried several different sized drifts.

I was able to bang out the roll pin towards the the
passenger side of the car. There is just enough room
to swing a hammer in there, although is would have
been much easier if I had removed the driver side tie
rod. I did not and got the pin removed. Others have
reported working through the passenger side wheel well
and banging towards the driver side.

Once the pin is out, the cylinder may or may not come
out easily. You will need to find a long solid drift
or solid piece of wood and drive the clutch cylinder
towards the rear of the car. Mine was "stuck" and I
had to actually apply heat to the top of the trans
housing with a blow torch. Took a long time to heat up
top of the trans housing to loosen things up. A few
cycles of heat and banging and it was out.

This work done on a 85 Coupe with LHD. Work on a 4000Q
will be similar.
