Thread: Salisbury oil quantity

I always overfill mine to help lube the maxis and hubs. About 2.75 litres I try to cram in there
Been thinking about a rockcrusher, But worried it will come too close to my longrange tank. Does it protrude rearward much more than the standard cover Brian?

Well, it's 8mm thicker for starters, and where the name is cast is a reasonable shelf.
I can measure the depth in the morning JC.
Easy enough to do, just run a straight edge across the back and reference to the diff housing face.

Sorry rick130 your were correct I should have looked at the supplement. Get my info correct next time

I have corrected my post.

No need to apologise, my comment on rijidij's post wasn't aimed at you, it's just always amused me when I see multiple answers all saying the same thing.

OK, the height of the diff cover is 88mm from the ovalised section where the name is cast to the diff housing.
Add 1mm or so for a gasket if used, I used Loctite 518 gasket eliminator.

I'd also suggest a 75W-110 or 80W-140 gear oil as we've seriously compromised the heat shedding ability of the diff with the cast cover.

I know that a 75W-90 oil will generally allow lower running temps than an 80W-140 but this is dependent on oil volume and the ability to transfer that heat to the surrounding air. The oil capacity in these diffs is tiny compared to the big trucks that I have some data on regarding running temps and a Sals runs pretty hot at the best of times.
8mm nodular iron has pretty lousy heat transfer compared to the 1mm tin plate of the OE cover.

i cant see any problems with over filling diffs, yes some oil may leak back out if the seals are old. If the breathers are breathing theres no pressure. I parked my s3 with salisbury on slight slope with car ramps under rear wheels to get it high then filled the diff probably about an extra litre no leaking at all, i did this because having owned and serviced toyotas that use greased wheel bearings i just wanted to make sure oil got to the bearings

I've just refilled my rear diff. for the first time expecting to need 2.65 litres as per the book, but it took ~3 litres to fill to the plug (~38mm).


I assumed i was in Salisbury country???

Serial # CO8...

Been looking everywhere to find out what all the serial #s for Rovers are but can't seem to find much info. on diff. codes.

Anyone know why i'd need 3 litres in there?
