Salisbury oil quantity

[Bearman]

I have just fitted one of those SOLID or ROCKBUSTER Dana diff covers to the Salisbury on my County and was wondering if anyone can advise me the correct quantity of oil to put in the diff. The inspection/filler plug is a lot higher on these and I want to raise the level a bit to ensure oil to the stubs/wheel bearings but I am unsure how much is advisable to put in there. Any help appreciated...Brian

how much higher is the filler

i would imagine you could still fill the diff till it comes out of the filler

[Bearman]

The bottom of the filler is about level with the top of the axle tubes. I think this is a bit too high.

yep must agree that is high, somebody will post the correct amoount required

[weeds]

without having a look at mine, could you have put it on upside down?

[Bearman]

It will only go on 1 way. I am pretty sure someone has talked about the quantity before. I would imagine about a quarter to halfway up the axle tube would be ok. Too much and there is nowhere for expansion to go.

:lol2: nope... ;)

They are designed for a high pinion diff, so the filler is well above the axle centreline.
The correct quantity for a Sals is approx 2.3 litres, but I fill mine with at least 3 litres so it lubricates all the way down to the wheel bearings too.
I was running probably 3.5 litres for close to 18 months.

Capacities (approx.)* Litres Pints
Front differential .......1.70 3.00
Rear differential
90 Models ................1.70 3.00
110 Models ..............2.26 4.00



Taken from the rave CD.When I did mine the other week I added an extra Liltre 2.7 litres in total to lube the stubs/wheel bearings.

I have been advised not to fill up to the higher filler hole level. My workshop manual says 2.3 litres for the rear Salisbury diff.

they're Rover diff quantities, not a Salisbury. ;)

geez, if you did, you'd end up with about 7 litres in there, which strangely enough is how much a Nissan Patrol high pinion front diff takes...

thanks for agreeing :D

I always overfill mine to help lube the maxis and hubs. About 2.75 litres I try to cram in there:twisted:
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.

[MacFamily]

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

I have corrected my post.

[rick130]

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. ;)

[rick130]

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

[reeksyofoz]

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).
:confused:

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?

Use the ARB diff covers.
The ARB items have a dip stick.(water tight )
I have two fitted to my 101 landy and the gas tank and standard diff cover just use to kiss on full suspension flex.
Now with the ARB cover on it clears.
The ARD cover is about 8mm thick too with the correct bolts supplied making the whole thing a straight bolt up fit.
The ARB cover was designed to be more compact.
About $200 dollars
