limited slip diff POWER LOK

[mgcjag]

Hi new to the forum & just purchased a 1969 Uk spec S2 2/2 been doing the usual on a new car & greasing up & changing oil etc...however Im a bit confused over the Diff & what oil to use. First what diff do i have? theres a tag on one of the diff bolts but cant reed whats on it. the workshop manual says that all series 1 & 2 have the LSD with powet LOK, but reading the original owners handbook it makes a reference to different oils for Power Lok & non Power LOK......can you help...Thanks Steve Hook

To check whether you have a LSDiff or not, jack the rear wheels off the ground and spin one wheel, with a standard diff the wheel on the other side should rotate in the opposite direction whilst a Limited Slip Diff should rotate in the same direction.
You would need to select neutral,ensure handbrake is off and check for any sticking brakes , hope this is helpfull,
regards, Mike.

You need to use a diff oil specified for LSD e.g. http://tinyurl.com/3yg72xl or you can add the Jaguar specified additive to stop the plates clicking:


The diff ratio is on a tag attached to the casing e.g. 43/13 - dividing one number into another will give you the ratio, in this example 3.31.

There should also be a similar tag marked "PL" on a Powrlok diff.

I have 2 tags: one with 46 over 13 meaning a final drive of 3.54 and one tag saying BP-L.
I assume this denotes (in another way?) that the diff is blocked. 25% or what might it be?
