[ROVERNET - UK] P4 105S Clutch

[Alan FRANCIS]

Hi Peter,
	   Had a similar problem myself about 6 months ago. I contacted the Land
Rover Series 2 discussion forum www.series2club.co.uk and got the answer
enclosed below. With my former access to part number cross reference and
suppersessions I know for a fact that some P4 part numbers change over to
Land Rover ones still current today.The clutches were in effect the same
originally. With regard to the spring pressures I wouldn't worry to much. If
the same part number was the same (and it was) then the pressures would have
been the same originally. Mine had the 2 dowel arrangement and I would
assume so has yours.
regards

Alan Francis (Part Viking)

 The Series 2/2A Land Rover uses two different clutches. All 2 litre engines
(petrol and diesel), 2.25 petrol engines and early 2.25 diesel engines use a
9" coil spring type clutch (part nos 231888 for the cover and 275811 for the
2 litre plate and 540519 for the 2.25 petrol ot 601294 for the 2.25 diesel
plate - I think the difference is in the damper springs or lining material
and not the dimensions). Later 2.25 diesel and all 2.6 petrol engines use a
9.5" diaphragm spring clutch (part nos 571228 for the cover and 271712 for
the diesel plate and 561536 for the 2.6 petrol plate) which was optionally
available on the 2.25 petrol.

The two types of clutch are not directly interchangeable due to different
dowel arrangements in the flywheel (the coil clutch has two, the diaphragm
three dowels), however this problem can be overcome. You should be able to
pick whichever clutch matches you're original type (coil or diaphragm) and
fit that. One important thing. Don't be tempted to buy the Series 3 type
clutch cover. Its a 9.5" diaphragm unit similar to the 2A, but it does not
have a boss in the centre for the release bearing and as a result requires
the release bearing to be much closer to the clutch than with the older
covers. The result is normally a clutch that cannot be released.

This is my first posting, though I have been following
the topics on the Rovernet for some time. But now I
would like some advice.

I am replacing the worn clutch in my 105S and have
obtained a replacement through a local supplier. How
can I tell if the springs and therefore the weight of
the pedal will not be greater than the original yellow
spring type? I'm concerned because on the side of the
box it states that it is for L/Rover and R/Rover.
