In a Zerk quandary!
My TR3A clutch cross shaft is fitted with a Zerk fitting on the drivers side, the same size Zerk is supposed to be also fitted on the passenger side end. My cross shaft has a much smaller threaded hole on that end. This could have been cobbled together with a later TR4 shaft ? Or...Moss mentions a shaft with no grease fittings. Anybody else have a similar situation and does it really need a fitting on that end if so what size?
Cheers,
Colin

I think that shaft did originally have a zerk there, but something is plugging the hole. Very likely the remains of a broken zerk.

The zerk is obviously not essential, since it was deleted on later cars. Still, it would be my preference to restore it somehow, so you can lube that joint occasionally. They do wear faster without an occasional shot of grease.

But, I wouldn't pull it apart just for that; and I don't see it as critical enough to try doing anything with it still in the car. So my suggestion is to wait until the gearbox is out for some other reason (next clutch job, maybe) and deal with it then.

FWIW, here's how I added zerks to the Stag (which doesn't really have room for them on the shaft)

Thanks Randall,
There doesn't appear to be any thing plugging the hole, I can slide a small diameter wooden dowel in there.
I think I'll go with your plan to wait until a later date, I'll squeeze a little grease in there and add a small screw just to seal it up.

Is it threaded? Might it be possible to simply thread a Zerk into it?

I seem to recall some Zerks are in two pieces with the larger threaded portion being a base into which a smaller threaded portion is fitted.
