The 'E' Type Forum

Hi guys,

I am finally about to order a clutch slave cyl.

The car is a 4.2 S1 2+2, March 1966.

On the car I found a 95 mm long cylinder, Lockheed (?) no. 3232-6480.

SNG lists a part no. C24145 as correct:

Then, using google, I found David Manners to list C29801 as an alternative part:

Getting back to SNG, they do list C29801 as well, showing 95 mm in the description, but they say it is for other E-Types then my 2+2 (the 2+2 is not shown in the list).

I do have found an adjustable rod, but IIRC no spring (not sure, say 90%).

I have fitted the modern smaller diaphragm clutch (had to use the smaller set of holes on the flywheel, it came with both sets of holes).

What should I do ?

Hi Carsten...have a look at this recent post......i listed the types and related chassis numbers /viewtopic.php?f=3&t=9381

I am not sure wether I understood everything Infound in the various posts, but it seems that C24145 is the correct item- I will try this.

I thought about fitting a remote bleed nipple. Anyone tried this ?

And I tried to understand how the travel of the hydrostatic version is limited (when pedal not depressed) but could not find an answer.

I see in Haynes that there is a spring and a small cylinder. To me it looks like the spring in the slave pushes the small cylinder outwards until it sits against the circlip. But is this the "resting point" for when the pushrod has the shown 15 mm free travel ?

Or does the small spring not always push the clutch main bearing against the backplate ?

I still try to understand the hydrostatic system.

The old part I removed from the car has a circlip so the piston cannot escape. Iirc when I pushed it in it would slide up all way back until it stops due to the circlip.

Today the repro part arrived. It has no circlip, and I can pull the small piston with my finger, below is a metal plate. The cylinder does not fully escape, because the spring only pushes it 3/4 of the total length.

If I now put this in the car, then the small cylinder will stay at the 3/4 position. The pedal has its own spring, so this does not put any pressure/ fluid into the slave.

Then, there is a 15 mm gap / clearance to the clutch fork. The adjusteable rod is then loose ? And only held in its place by the rubber cup on the slave it is put through. Effectively, loose.

Correct ?
