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

Re: sump and gearbox diff drain plugs af sizes
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!
Re: sump and gearbox diff drain plugs af sizes
I can confirm the diff is 7/16" (or 11mm) square.

Re: sump and gearbox diff drain plugs af sizes
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?

Re: sump and gearbox diff drain plugs af sizes
That's an expensive toy just to shift a filler/drain plug. But - it will do the job!

Re: sump and gearbox diff drain plugs af sizes
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.
Re: sump and gearbox diff drain plugs af sizes
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!

Re: sump and gearbox diff drain plugs af sizes
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.

Re: sump and gearbox diff drain plugs af sizes
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....

Re: sump and gearbox diff drain plugs af sizes
round plug square hole. doesn't get around the fact that I need an 11mm square and a hex socket for both!
