Part number is irrelevant actually.

The Original number is obsolete anyway and has been upgraded over the years.

I bought about 15 when Scimpart closed and there were at least Two numbers on the boxes, but they ALL FITTED.
Either get one from a club trader or do an internet search.

IIRC Mk 3 Discovery is a straight fit, but not able to confirm at moment as records not within 5 miles.

Hi , Thankyou so much for your replies . The reason I need the part no is I want to convert back to original to give me a much lighter pedal . I drove a friends 6a with an original Lockheed system and the pedal is much lighter than mine . The set up I have at present is Land Rover discovery . I have been given a Lockheed clutch master cylinder and the same source has many slave cylinders but no parts book ! That’s why i am looking for the original parts number or superseded numbers .

I’ve never heard the standard system called “light” :D

The important bits are bore and stroke - the parts in the link above are series/defender, not disco.

Hi Scimjim, when I said light I did not mean light as a modern car . The comparison I experienced today between my car and a friends convinced me to make some changes . If the genuine parts can be obtained imho that’s what we should be fitting .

When I said what I had fitted was disco Master and Slave , I took that information from a posting the previous owner of my car made in 2015 .Thats what he said he had fitted .

Thanks again for your replies.

If it’s heavier than standard then you’ve not got the pairing of LR master/slave in the link Jim posted above. There are a few LR combos and some are heavier than others when fitted to a Scim.

If it helps original Lockheed master is 5/8 inch (0.625" or 15.875mm)
slave is 7/8 inch (0.875 or 22.225mm) giving a ratio of 1:1.4
Landrover defender 4 cyl master 19mm
slave 22mm giving ratio 1:1.315.
Since a smaller master gives less force required for same slave size (but longer pedal travel) then it can be seen that the Defender at a ratio of 1:1.315 needs more pedal pressure since it has a larger master bore but not much larger slave.

Just for info in case you can find an older store the LDV comercial van slave at 22.2mm is part No. WC3611 and WC3608 and are Scim equivalents.

If you really want to go into the maths and work out the actual pressures look at www.buckeyetriumphs.org/technical/clutc ... ations.htm.

I agree with your theory Dennis, but not your maths :D

I don’t agree ! If Lockheed had have had a cylinder on the shelf ie Land Rover , they would have used it . It is not just the size of the bore . It is the stroke , the configuration of the valves and the weight of the vehicle all have to be taken into consideration. Many months of work went into the specification, many trials were done . They never just created a Part number for the sake of it. I cannot understand when the parts are still available would you want to change the specifications of your pride and joy .
