Diff Oil change

Post by D366Y » Fri Nov 08, 2019 3:50 pm

Afternoon all,

Apologies if this is a bit of a dunce questions but the Haynes book of uselessness is pretty thin on how to do this...
I have the later diff/axle as it's for my laser so think its an Atlas (??) I know that there are the bolts on the back of the casing to take it off, change the gasket and bolt it back on again, the only thing I don't know is how to fill it up with oil again afterwards....?

Apologies if I'm being a moron!

Thanks
Danny

Not at all, there`s a filler plug on the passenger side of the differential casing, you can see it just behind the exhaust pipe, it`s either a 10 or 11mm square drive but if it`s not too chewed up a 3/8" ratchet will fit:

Yes, indeed, it`s a very old pic with an untidy old exhaust and tbh I`m thoroughly ashamed to have posted it - but it was the only one in the `archive` which showed the filler plug. Don`t worry though, it was replaced 10 years ago with this, featuring a single Jubilee super- clamp (or whatever they`re called) Like a Mikalor but more solid.

That's more like what we expect from you!
I hope you weren't genuinely "thoroughly ashamed" to have posted the original photo. It perfectly indicated the position of the oil filler plug for Danny, and also gave us a sneak glimpse of the underside of your wonderful Laser. :D

And do please make sure you can undo the filler plug before you remove the rear cover and drain all the oil out. If the 3/8" ratchet doesn't work (it did on mine) then a set of Stillsons or decent mole grips will do the trick. Once out I believe it share the same thread with plumbing fittings so can be replaced with one with a square protruding head for future changes.

I wish I'd read this before I went and took the rear cover off this morning then.... :shock:
Was such a bitch of a job just getting it off to be honest! How puts an anti-roll bar directly in front of the bolt head so I can't get anything on it?? What a stupid idea - although apparently less stupid than me not coming back here first! :lol:

Whoever you think may take an interest.....you can pretty much rule out wives and mother's , no sense of humour there, best plan is to simply leave it to be "discovered" , and the women's toilet is the best bang for your buck :lol:

Not much use to you now Danny I know, but I guess you could have used one of those fluid hand extraction pumps (which many use for the gearbox oil) and sucked the oil out from the filler hole, then just put fresh in although I think you wished to change the gasket anyway.

Thanks for the replies guys - I wanted to take the diff cover off as it looked like the gasket had failed as there was a small pool of oil on the bottom of the diff, and while the cover was off I thought I might as well give it a dollop of paint to keep it from rusting

Anyways, out there last night, covered cover in sealant, gasket on, more sealant, everything back in place, greased up the bolts, put them back in, torqued up, got myself a little pump thing to put the oil back in as well which worked a treat - I was well chuffed!

After letting it warm up and a quick run through the gears to make sure it didn't piss everywhere I treated myself by going for a spin to tesco to pick up a well deserved refreshment :beer: and thought I should check quickly and make sure it was all still OK....

Two, maybe three miniscule pin-holes starting right in the middle of the cover just off centre. :doh:

Pleased I did it all, pissed off I now need to do the whole thing again because it was a bitch of a job and one I'd hoped not to have to repeat too soon :lol:

That`s a bloody shame! Maybe just rub down the area, de-grease, and slap a bit of chemicall metal on the wound. Will give you 6 months so you can at least do it in the summer? (Halfords do a 2 pack, `Plastic padding Super Steel` which is very strong and sets really quickly.)
I mean, there`s no reason I suppose why you couldn`t effect a permanent repair if they`re just a couple of pin holes, obviously it only rusts from the outside so if you were pretty thorough and gave it plenty of paint, it could last a good while?

They normally rot around the mounting for the handbrake rod and the clip for the brake pipe.

Yeah mine has gone just to the right of these points - will make sure I check next time before I put it all back together!

I have been trying to think of ways to 'bodge' it over the winter and I'm sure I'll come up with something so I don't have to do it all in the dark again like I did on Thursday :lol:
Doing these things outside on the drive in in the dark and cold does make it infinitely harder than it needs to be, and I'll just have to do it all over again come spring - at least then I'll be a seasoned professional :lol:

Use some epoxy resin - as a temporary solution it works perfectly
