1960 A10 clutch not disengaging

[Roy D Route]

While on a short ride my clutch began to drag. I ended up taking all of the adjustment available at the handlebars and it still dragged eventually to the point of stalling when putting the bike in gear.

I took the inspection cover off to see if the adjustment at the pushrod was off. It seems now like the clutch is locked up somehow and the pushrod won't move at all to disengage.

Before Going into the primary side, I hope that those on this site more knowledgeable than I might have suggestions for what could be causing this. Thanks.

  Probably not a bad idea to rip the primary cover offoff and have a look, otherwise you'll have a million (slight exaggeration ) suggestions that may or may not be any help...!
   My bit is that the pressure plate springs have become maladjusted..?

G'day Roy.
Yep duTch is right so here's a suggestion. Pop the oval cover off the right side of the g/box and adjust the push rod there (back off handle bar lever first). Sounds like springs are adjusted unevenly so the pressure plate doesn't lift square wearing the end of the push rod quicker than normal, and or the grooves worn in the basket and center are holding the plates from releasing. Best remove the cover and look.

Loose mainshaft nut.

[Roy D Route]

Is the main shaft nut the same thing as the clutch hub nut? A fellow on the Brit Bike forum suggested it might be the clutch hub nut. Looking at the parts drawings it looks like the same thing. Looks like the primary case is off soon. Thanks.

Yep, same animal. Funny how different parts are called different names (English gearbox = American tranny, English mud guard = American fender) around here their all duppers that hold the dodad.

It's not the nipple pulling off the cable is it?

[trevinoz]

There is a nut on the opposite end of the shaft which is what the other person may be referring to.

Trev.

 Good call   Wilko, and I think Trev means the nut inside the outer cover, that'd also do a similar thing, though not sure how much end float there is in the shaft(without the nut done up which reduces it to zero when tight ), I noticed a reasonable admit when I was playing with my spare box the other week(as we do )
 Be worth checking them both, starting with the easy one..
