transmission oil.......how much!!!

[piperdog]

hello,can you help...my rear diff has decided to leak oil {coming from the wheel )is there an alternative to fords oil and will anything bad happen if i put 90 in ...thanks tony

[Luke]

taken from nighthawks answer in another thread!!

A specific oil was used in the Transits RWD axle, any non ford oils should meet WSL-M2C192-A

The correct oil is thinner than EP90

btw no need to ask the question twice - i'll delete the other one!!

[piperdog]

thanks for the quick reply.....my local ford hasnt got any in stock and the van is needed for monday ,does any know if putting in 90 will cause trouble

[madmark]

go to any store ,ep90 is what you want!

[piperdog]

thanks ,thats sown that up,im now going to post another thread on th art of changing the seal

[Nighthawk]

EP 90 is much thicker than the correct oil.

When you say it's leaking at the wheel end of the axle, what vehicle do you have ?

Type 51 single wheel or Type 53 dual wheel ?

Depending on which axle it is, the method of replacing the failed seal is different.
On one axle it's fitted into the axle tube and on the other it's in the hub.

manual says
hypoid ford spec SRM2C-9102-A
gear oil ep85-90 (GL5)

its a twin wheel ,rear wheel drive

[piperdog]

ref. the oil is that for a 51 model ,thanks

[Nighthawk]

Twin wheel is an easy repair, there are 2 seals inside the rear hub, the inner bearing is a greased item and the outer bearing is fed with diff oil which travels along the ½ shaft.

The oil is held back by the smaller seal between the 2 bearings, it's often overlooked when repairing the hub as people are un aware of it's presence.

[piperdog]

thanks for that ,pardon my ignorance,so i guess i take off the wheel hub,remove the shoes ?and the half shaft and then

[Nighthawk]

The shoes can be replaced with the hub in place, but if the axle has leaked oil, the hub must come off.

Mark the wheels in relation to the hub and also mark the drum, putting them back in the place they came off will greatly reduce the chances of brake judder.

the ½ shaft will come out when you undo the bolts, the drum will* slide off the hub.

with the drum off and the shaft out, you'll need a BIG socket to undo the nuts, once the nuts and the locking tab are off the hub will slide off the axle tube.

replace the seals and make sure everything is clean, re build the lot making sure to set the preload on the bearings correctly.

Jobs a good un

* the drum might be tight to get off, a couple of clacks with a large hammer will usually do it, if your unlucky though, you'll need to adjust the shoes down to enable the drum to slide free.

If you have little mechanical experience, let a garage do it. Brakes aren't the right thing to take a guess on. and if you overtighten the bearings, it'll chuck it's hand in very quickly.

BIG THANKS im going to do it saturday, as i clock up about 800-1000 a week , ill keep an eye on the level...hope its not too big a leak

[piperdog]

forgot to ask
back to origonal post ,can you agree topping up with 90 will be ok ?

[Nighthawk]

I can only advise the use of the correct ford oil m8, i hope you can understand that

If halfords, autoparts or any other motorfactor give you different oil thats fine
