Dave Many thanks for the xjs info.

Does anyone have a typical value of the total turning torque for a refurbished diff. By this I mean the inch pound value of the input shaft when the diff is fully assembled on the bench

Hi Rory,

Yes I definitely needed a press. I've acquired a good range of short pipes that slip over the shafts.

Morning Steve,

Many thanks.

Is it normal to have a 10 thou difference between left and right rear hub preload spacers. I've replaced my rear hubs because when I stripped them initially they were blue. That is well heated. I assumed they'd been run dry but now I wonder if having been set up with 110 thou shims, they were in fac...

Hi steve,

It's from my jaguar 4.2 spares manual, 1965.

Al

Are the rear hub carriers left and right handed.

The spares manual shows different part numbers but my carriers, series 1, 1966 2+2 look the same physically and are dated July 1966. No part numbers shown on the carriers.

This looks to me to be uniform mesh across the gear from heel to toe.

Backlash 0.006

Latest update. 0.044 under the pinion race up from 0.029.

Backlash 0.008

Latest update on tooth pattern.

Tried the turmeric in grease. Ended up using nappy cream!

Backlash is 6 thou.

Having been laid up for the best part of 6 weeks, I'm finally getting around to finishing my diff rebuild. Output shafts set up, no real issues Clutch plates replaced and replacement set of gears installed End float shims defined for diff side bearings and preload Run out is zero Because it's a 2.88...

My companion flange on the input drive to the diff has a groove from the oil seal. Has anyone had experience of using a speedy sleeve to overcome potential leaks from this type of problem. If so, were there any issues regarding the life of the oil seal because of the increased shaft thickness. Many ...

Hi Andrew, many thanks. 70 - 80 lbft it is then based on the "Drive gear bolt" data

Hi Steve, Thanks for that. I decided against the Quaife. Nice unit but dimensions weren't quite right against the 4hu. At least on my measurements! OK if you had a lathe. I used another salisbury 4hu. I was lucky. An old friend had a partially stripped unit F.O.C. It had a good inner lsd. Just neede...

Hi Steve,

I'm talking specifically about the internal lsd case. With the o/p shafts slipped into the ends should there be any noticeable rotational movement of gears within the diff case. I'd assume it should be locked.

Does anyone have the torque setting values for the crown wheel bolts on a 4hu LSD.

I've searched the manuals to no avail. But I have come across the following range of values, online. 50 lbft, 80 lbft, 100 lbft.


Many thanks.

Finally got around to reassembling my failed diff. Replaced all the gears and a new set of clutch plates. It's torqued down ok. Quite balanced as it settled so my thoughts were, internal alignment must be ok! Advice please from those with more experience than me before I start to rebuild the carrier...

Just out of interest, does anyone know why there was a change in grease seal orientation on the outer pivot shafts between etype and xjs of the same period of manufacture. I have an xjs haines which shows them as seal inwards, whilst etype is seal facing out. All similar set ups regarding the carrie...

Hi both, Wheel arch showing location of tab and I do have a new boot floor.


It could well be that they should have been folded up inside the boot.

Could anyone tell me what these tabs are for. There's one in each wheel arch.





Many thanks

Alun
