Hi again - in my quest to replace the non-standard inner timing cover on my '61 Super Rocket with the tacho drive version, I've decided to remove the oil pump just to see how things are. Seems rude not to whilst I'm in the vicinity.
No problems I can't sort out with the pump - but discovered that the crank pinion has about 2mm axial play which looks really odd. A bit of research tells me there should be a washer in there between the oil worm drive and the pinion. There isn't.
Simple enough to fix, you'd think, but how on earth do I remove that lock nut ? I've bent the washer out straight again - and yes, I know it's a left hand thread, but it won't budge. I'm in danger of buggering up the nut in my efforts so thought I'd seek advice before going on to more drastic solutions.
I've tried locking the shaft using the narrow hex on the worm drive - but it's too narrow for a decent spanner and laughed at my home made narrow spanner.
Next I tried locking the rear wheel and putting it in 4th. I can get a lot of torque on it that way but eventually the clutch slips and the nut doesn't.
I didn't really want to get into the primary chaincase - but maybe that's what I'll have to do. At least, if I do, the fact that it's a left hand thread should mean I don't undo the cush drive nut - unless that's LH thread too ! I don't think so, at least it shouldn't be.
Any ideas would be very welcome.
