Title: Socket size please
Post by: RoyC on 08.07. 2019 12:15

Can anyone please tell me what socket size to order to remove this screw ?

Of all the socket sets that I have, not one will fit.

Thanks.

Have the same problem. Molegrips seem to fit OK (be gentle)

Hi All,
Those studs are BA but usually either a 7mm or a 1/4Af will fit
There are two sizes

It's 4BA.
I have a 4BA open ended spanner that fits ok but can't get at it very easy so will order a socket.

Thanks for the responses.

Roy, If you have no suitable socket to remove the points retaining bolt, does this mean the points have never been off to be cleaned and checked under your ownership? I hope you have not invested in electronic ignition when all you needed to do was give the magneto a bit of TLC. Or is there a further underlying fault?

 I use a good old authentic Lucas Girder Wrench and a light touch.

 Nice Jaguar, class axe.

First time that I have ever touched them.
Got an intermittent misfire on the left side.
I have only rode the bike twice, got no confidence in it not breaking down.
I am hoping that the new ignition makes it more reliable.

Yer.
Got a few more.
