hi there, what's the sump, gearbox filler and drain, diff drain plug sizes in af sizes? will try and do these tomorrow.

thanks!

I know the gearbox filler is the wheelbrace size........ The diff drain plug needs a square - 7/16" I think. Sump may be 1" AF, or maybe slightly smaller. Take care to turn it the right way - and don't overtighten it. When doing the oil filter - make SURE the spring and plate are present under the element.

Sump plug is 3/4" AF, can't remember what the others are.

going to check the filler plug first before i drain the thing, will try and find my wrench with all the bits and bobs coming off it for sump, drain plugs etc!

I can confirm the diff is 7/16" (or 11mm) square.

checked the filler plug. i put the universal swiss army thingamy wrench in the hole, is there usually a little bit of play on the wrench? i put a lot of weight on it anticlockwise several times, no joy. the car nearly came off the road. then i tried tapping the wrench with a little hammer, nothing. i tried soaking in wd40. it seems pretty tight. glad i tried the filler first, imagine if i drained the thing! any ideas? put some heat around it with a gaslamp or directly onto it?

This is the filler plug for the ?????

diff. its on the back of the casing. I will need to put a socket on a breaker bar.

can anyone find a set of sockets on machine mart site with the 11mm square or 7/16s that I can put on a breaker bar?

found them.

17 quid. is the oil drain to suit a hex head ie this set or an standard af socket?

That's an expensive toy just to shift a filler/drain plug. But - it will do the job!

i might just get a single 11mm but is the oil drain plug a hex hole or a hex head taht a normal socket can bite on to? thank you as always for you help.

Which 'oil' ????

lol, engine oil? got to keep the moggie alive!

It's hexagonal headed, don't get me wrong but I'm suprised that you can't just peer under and see what type it is!

i want to make sure i have everything to hand next time i get under there! (i am impatient) and i got fed up with not having the right square heads for the diff. i have a set of hex heads and af sockets etc.

looks like i will need to ease the diff open after a warm run with a breaker bar, if it feels like it's not going to go, i will heat up the casing a bit.

You've missed my point. However that aside, you originally said engine oil---now it's the diff, in which case the plug has a square hole!

Concentrate on ONE problem at a time to avoid mis-understandings and possible mistakes being made....

round plug square hole. doesn't get around the fact that I need an 11mm square and a hex socket for both!

It's NOT 11mm - it's 7/16"....
