Title: What size socket?
Post by: Felters on 04.09. 2011 07:32
What size Whitworth socket is the oil drain plug on the oil tank please? Looks like the same as the top of the forks and seems to be about 33-34mm or 1 3/8" across the flats.

Slowly building up a collection of Whit stuff but it looks like this one will be a one off buy rather than part of a set and I want to get it right.

Cheers
Mike

In Whitworth terms it seems to be between 5/8" whit and 3/4" whit. I use a 1 - 1/4" A/F socket.

I now use a 33 mm socket, with the recess on the end that grabs the nut turned off square, so it locates fully over the fork top nuts fully as well as being OK to use on the the oil drain, to tighten and undo these things.  I use a piece of chammois leather with a hole about an inch in diamater cut in it, to go behind the oil drain when I unscrew or tighten it.  This means that at last I don't leave circular tracks in the paint in the recess in the oil tank.  The bit of leather came from my wife's going away outfit, dating from 1969 *smiley4*.  We were all a lot younger then.  And she still has her Tiger Cub!
