Burman Gearbox Clutch Adjuster

[Martyn Goodwin]

The Burman gearbox has an entry hole in the cover for the clutch cable. This hole is threaded 3/8 CEI which, I understand, is intended to take a adjustable cable stop and locknut.

Was this adjuster an original feature of the Burman boxes on Vincent singles as I have never seen one in place on any bike I have viewed.

If it was not installed "as original" by the factory, what did the factory use to stop the cable end simply being pulled thru the 3/8 threaded hole into the interior of the gearbox?

An unthreaded spigotted ferrule. It is available from the Spares Co. Unfortunately I am not near my Spares list so cannot quote the part number at the moment.

G94/1 SS I guess - would this also fit a Series A Burman box ??

One can only imagin that the thread was to take a "Threaded Adjuster" originally, but it's location would make adjustment interesting, unless you had the hands of a small monkey.......mmmmm, A fine threaded adjuster into alloy......sounds like the primary adjuster on the twins, but hey ....they never strip do they......MUCH.

Hi Greg,
I cheated
I made my own adjustewr with double locknuts which is a floating fit in the hole, thus can easily be removed and adjusted ;-)

Hi Martyn I have the same as mentioned by Hugo, can't say I am at all impressed, I was under the impression that adjustment was carried out by mid cable adjuster?

I have two 'C' Comets and three Burman boxes, one kept as a spare. The spare one has the threaded and slotted adjuster. This was used on other makes with Burman boxes. As you say on the Comet it is a pig to get at and adjust in situ, hence, I suppose, Vincent's use of the un-threaded ferrule. The non-threaded Vincent Part No. is G94/1SS Comet Clutch Abutment.

Vincent chose to provide adjustment by cable so the threads in the inner cover serve no purpose on the Comet and Meteor. Hugo,even more of a pig for access is the Comet Valve Lifter cable; that can be a real struggle!
