Diff drain and refill

[Mr Cerbera]

Wotcha !

Well, I thought that this would be a cinch
BUT [Quelle surprise]
none of my spanners fit (what I think is) the drain plug.
I have tried 14mm and 9/16AF (too small) & 15mm (too big).
Don't tell me that I have to go to /64s, Shirley ??

Any geniuses out there to help ?

Edited to change 9/16 to too small rather than what I originally wrote

Just wait till you look for a spanner to refill it!

Can we have a pic of said plug?

Been a year since I did mine but didn't have
Any issue with it.

I do however have metric, imperial in /32 steps

(Oh why ,oh why, did I give my old man's Whitworths away )

Just managed to break the seal on the Differential drain bolt by putting a 3/8 drive ratchet into a wheel spanner handle and jacking it in a counter-clockwise direction with a two-ton jack

Looks like it's gonna be a looooong weekend

The filler is on the right hand side half way up obscured by the chassis
The spanner size is oddball like 23mm slim spanner iirc......

23mm They all look relatively 'nomal' sizes to me.

Am I looking at the wrong side of the diff ? i.e. should I be looking at the front of it ?

Ta !

Afternoon all,

An odd ball size indeed, thanks for the post.

Any issues getting it undone? Also, is the metal tag simply for identifying the diff or does it serve as a seal too?

Access to it is a nightmare but I think that was also true for the previous mechanic as an adjustable was all that was needed to get it undone.
The metal tag is just a warning but it is retained on the bolt by a seal.

A la .....

Oh, and the drain plug did come out with a 15mm and an extension bar and a 2-ton Jack.



BTB, the handbook recommends Mobil SHC 80W 140 ID.
Does anyone now what the 140 ID bit means ??

OK, No Probs. just found out HERE

Oh, and just in case anyone else looks at this thread for clarification of location.

The filler plug is located on the right hand side of the Diff case just in front of the half axle entry point....

The last time I had to undo a bolt head that had no usable corners, I managed to get it off with a pipe wrench. Mine was doubly handy (sic!) as it had dirty great handles on it.
(and that was 17mm as opposed to the rain plug's 15mm)

Best o'
