Hi and what size

Hi all, first post and first question!

Could anyone tell me the size of the male square drive on the differential fill plug?

Cheers

Are there many C3 diff variants?

I think a standard 1/2" drive fitted mine. I didn't need a special tool and with my basic workshop gear it must have been something simple.

Thanks for the reply, I'll have another look but the square looked bigger than 1/2 inch to me.

Re: Hi and what size

Sorry Golden. I've given you a bum steer there. I've just been out to check and I wasn't even imagining the correct shape for the plug. I thought it was a female socket needing a male tool.

So I've measured it for you. It needs a 5/8" spanner.

Re: Hi and what size

For some reason these things always seem to be done-up extra tight have the 'open ender' slip off the two flats when trying to undo (they are only a grap cast plug after all). Iv'e had better luck using as large an adjustable 'open ender' as possible and using a bit of extra leverage if possible.

Re: Hi and what size

This turned up today guys which I'm hoping will make doing the job in situ laying on my back much easier

Assuming it'll come undone
