Shaft repair sleeves

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 ...

Re: Differential advice

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...

Re: Differential advice

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.

Crown wheel bolts

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.

Re: Differential advice

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...

Outer pivot, rear hub 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...

Re: What are these for

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.

Solid pinion spacer

Does anyone know where you can get the solid pinion spacer, p/n 8029 rather than the collapsible version. My diff came with collapsibles on both the pinion and output shafts but having read most of the previous posts concerning ccollapsible spacers I'm inclined to go the solid route if I can get the...

Re: Quaife diff

Hi Steve, Yes I think those are the options if I want to fit the Quaife in a salisbury shell. I also checked the blackline and it's exactly the same as the Quaife,. That is the crown wheel flange being 2mm closer to the non drive end. I borrowed the Quaife diff, so at this stage I wasn't in a positi...

Re: Quaife diff

Hi Bill,

I do have a series 1 but unfortunately the diff is a replacement dated 1990, which puts it in the xj6/xjs category. As such the shims are between diff bearings and case. With the Quaife this would mean I have 37thou to make any adjustments due to the Crown flange position.

Re: Quaife diff

Hi steve, The use of spacers with this Quaife diff will make the problem worse. The spacers normally fit between flange and crown wheel. I know that Blackline diffs use spacers with the crown wheel but I've not been able to get hold of the mechanical drawings for their diffs to understand the implic...

Quaife diff

I acquired a quaife diff to double check suitability of fit to replace my damaged unit. Overall this is a great looking unit. Dimensionally it will take the standard diff case bearings and the jag crown wheel would physically fit. The problem is that the flange which the crown wheel bolts to is almo...

Set of diff gears

I've been looking for a set of internal gears for the 4ha diff carrier but not found anything yet. Has anyone fitted a Quaife or blackwell heli diff as a replacement. If so, where there any issues.

Re: Differential advice

Looking at the spring you're correct, although how that popped so neatly around that bearing is another thing! Steve, I have a new irs cage from one of the usuals. It came with the car and it is for etypes. The mounting brackets as you say are something else. Is there a specific measurement regardin...

Re: Differential advice

Many thanks for the input so far. Having bought a partial restoration, I'm not sure if this diff has ever been fitted to this car. That's what you get for picking a job up part way. I cleaned everything up this morning because I'm still chasing the source of the debris, Bill, the spring I mentioned ...

Hi Steve, no it's one solid piece.

I was surprised to see the collapsible spacer. I thought these were a later feature.

Hi Steve,

Yes it does have a large nut, 1 7/8" with tapered bearings.
