AJS & Matchless Owners Club

Hi all from new (but very old...) member.
Just did a deal to px my 1960 G2 for a larger G5 and it's due to go away tomorrow.
Sods law it's sprung a leak - a good one too - on stripping off right hand cover the lead seams to be twofold.
1) from around the gear selector shaft 2) from inside the shaft itself which appears to be hollow.
I can understand the o ring on outer shaft leaking but from inside the shaft????
Can anyone shed light on this asap please????
To change the o ring do you simply unbolt the outer gearbox cover??
What about the leak from the inner shaft??
Also by sitting over the winter I've now got no clutch - anyone help??
Regards
Jock
ps I've been lucky for the last few years with it and sods law the day before it goes this happens....

Hi Jock,

There are 2 o-rings on the gear indicator shaft (which is inside the selector shaft).
There's also an o-ring in the outer case that seals the selector shaft. Some pics here:

Hopefully an easy fix!

What exactly does 'no clutch' mean?
Does it not free?
Does it slip?
Does the handlebar lever not move?
If it's been unused over winter the plates could be stuck together and need to be freed.

There is a mod for the outer o ring which is now a shaped seal instead, not sure of the part number off hand but it is the same number as the o ring but with and X suffix. Mine still leaks a bit from there despite o ring and seal changes!

I bought the new type 0 ring seals gear & kick shaft from the club site fitted them to my daughters G2csr and the oil is staying in the box now no weeping at all
shifter

Mine is nice & oil tight now around the gear change, but I can't figure out how the kickstart seal is supposed to work.
It seems to be designed to leak (unless there is a way to remove all end float from the kickstart shaft...). Perhaps I'm missing a shim somewhere?

Many thanks folks. Stripped down last night so finally know what I am talking about....maybe! 1 o ring missing from selector shaft - what a Â¥£â‚¬â‚© design - too used to working on oil free Japs. So now the leak is identified how the blazes do you get the end cover and that damn selector spring and pawl back in ?????

BTW lost the clutch because oil level had dropped and the pull lever inside rh cover had locked up.

"With care"
If you line everything up as per the photo, the cover should go on...

Its not playing ball
The spring just barely locates and as soon as you move the assy the pawl pivots ansd spring falls out
