Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 gear knob

Hi all, hope everyone has had a great Christmas.

I'm looking to buy a wooden gear knob from 'built by basil'. does anyone know the correct thread size, I assume it's the standard MX5 one 10mm x 1.25?

Cheers,

Martin

My 2012 car was 10 x 1.25.

Thanks, does it just unscrew do you know?

Thinking about this I decided to check the actual parts to make sure I'm remembering this correctly. When I received the car (used) it had an aftermarket shift knob (a #3 billiard ball!) which has the M10-1.25 thread. The original Morgan supplied knob, which I have, appears to have no threads at all, just a rubber internal sleeve which is approximately 10mm in diameter. I don't have the original shift lever which I swapped out when I converted to a forward shifter position years ago. My current shift knob is M10-1.25 thread.

So I can't definitively say how your gear knob is retained, as I don't recall what it took to remove the original shift knob. But a threaded knob will have thin lock nut under the knob which keeps it from spinning or coming loose.

Sorry about the confusion.

Edit: an update with a video link to Phil Bleazy doing an engine removal. The bit about removing the shift knob begins about 23:30 minutes in.

My 2013 car has the more forward mounted gear change and has exactly the same system as shown in Phils video, the 3 grub screws and plastic sleeve. As far as I know this is "standard" and any threaded gear change is a modified one.

So what is under the plastic sleeve?? Threads?

It's a time since I removed it but from memory, no threads, just a plain shaft. It's held on with the 3 grub screws through the collar.

Martin,
you will find below all the useful information regarding my purchase of a Gear Knob from Basil :

There are no set screws to fix the knob, just a first threaded aluminum ring, which serves as a locknut.

Thanks for that, I've got the original one off now and it was threaded the same as yours, just waiting for my new one to be made, yours looks awesome.
