Picon Biere Posted February 9, 2012 Share Posted February 9, 2012 A quick question for the gearbox gurus. I dont like the round gear knob on my 6 speed box and want to replace it. My question gentlemen is does the gear knob screw on, does it use set screws, is it an interference fit (unlikely but I though I would list it) stuck on or.... Any input would be appreciated as its too cold to go in the garage and start messing around with it. Todd Link to comment Share on other sites More sharing options...
Markiebabes Posted February 9, 2012 Share Posted February 9, 2012 I think from memory mine screws on, then a grub screw secures it HTH Link to comment Share on other sites More sharing options...
Mankee Posted February 9, 2012 Share Posted February 9, 2012 Yes, it's a grub screw securing it and then you unscrew the knob. Think it's a 3/8 thread but can't remember if it's UNC or UNF. Early gear levers like mine were Sierra levers with an extension piece to fit the Caterham knob. Later levers are shiny Quaife quickshift items.

skydragon Posted February 9, 2012 Share Posted February 9, 2012 I replaced mine with a turret-type knob, which a friend machined for me out of a piece of ally billet. It extended the overall height of the gearstick by approx 1/2" or so. I found the smaller and taller gear knob made gear changes far easier. something shaped like this here (but with cross hatching machined in for a better grip) Link to comment Share on other sites More sharing options...

skydragon Posted February 9, 2012 Share Posted February 9, 2012 ......to find 5th instsead of 3rd . Ho, Ho, Ha, Ha....you funny man you...(sod off ) I'll have it known, that after getting my gearbox serviced and this new gear knob fitted, that I haven't suffered a single incorrect gear change since...so stuff that in yer pipe matey (5th instead of 3rd was annoying...1st instead of 3rd was what really upset me!) Finished your engine yet? I'm assured it will be ready next week... Link to comment Share on other sites More sharing options...
Gavin H Posted February 9, 2012 Share Posted February 9, 2012 Just a word from the wise (well from me anyway) - be careful how large your new knob is (fnarr fnarr) before you commit. Mine was too big (oo ar) and split the leather on the gaiter (it forced the gaiter against the side of the hole (arf arf) and wore through in no time). 😬 Link to comment Share on other sites More sharing options...
