shift lever threads

[bowen]

I have a 1962 BT7 with a side shift transmission. The shift lever is the "s" configuration. The threads are damaged and I want to trace them with a die. Does anyone know the thread information for this type lever. size,fine, or course threads,etc.

thanks

Bowen,
My car has the center shift but Moss lists the gearshift knob as the same part number. Mine is 3/8" diameter with 16 threads per inch (coarse threads). Have a good day!

Speaking of the two types of levers used on the 3000 side shift transmissions, does anyone have an opinion why the factory made the change from a single bend to the double bend? I've only had experience with the single bend so I can't comment on why an extra bend would be better. Any ideas?

Bowen,

I ran a die down the shaft of my side shift(S-shaped BT7, like yours) and found that a 7/16 NC(national coarse)14 fit well, with very little slop, even though the thread gauge prescribed a 16 thread size would be a best fit. I found the 3/8 NC16 was, in fact, too snug and I think it might take off some metal. That may be because the chroming process adds some metal to the shift stick and gives it a thicker profile. If you can find a 7/16 NC16 that might be your best bet. But If your threads are crushed or rusted, try the 7/16 NC14 first. You might want to wrap some teflon tape to give it more "bite" when you screw the shift knob back on. You can always take metal off later if this isn't a snug enough fit for you, but you can't put metal back on......

Cheers

I hope you can, I have the centre shift and PO put an Aluminium Knob on with a grub screw to tighten onto the threads, but it revolves. Result - threads are shot to ribbons.
Plan is to remove shift stick, weld up threads, turn down the result on a lathe and re thread and re chrome. But that is for the future, it would be difficult with the offset stick but not impossible - it would mean a lot of careful filing and grinding first.

Why not just use a two pack epoxy to glue it on with?, or failing that butter it up with devcon and recut the threads?

I guess you could also turn the shift lever down to the next thread size that gives you some decent grip, and find an mating insert that could then be drilled and glued into the shift knob.
