It looks like they may have cured the rattly "you're-not-quite-in-gear-yet, mate" noises by adjusting the gear selecting remote control rod, but they reckon a microswitch needs to be replaced - something which activates the clutch disengagement valve so you can still change gear when the choke is on, and the revs higher. I'm not quite sure if I've put that right, so here's mac's description of it :
Some piccies from the green book and the parts catalogue (the microswitch is part 10)mac wrote: If the clutch is correctly fitted and adjusted it will begin to engage at an engine speed of between 1000 and 1150 rpm. By 2500 rpm. the clamping force will exceed 103Nm and will continue to climb as engine speed rises.
One problem arises during cold start/drive off - the engine speed with the choke engaged is higher than 1150 rpm. To allow forward or reverse to be engaged under these conditions the clutch housing is fitted with a vacuum operated servo which acts on a release arm carrying a bearing. This partially counteracts the centrifugal weights by depressing release fingers on the cover plate. This, when correctly adjusted can delay full clutch engagement until 2000 rpm. The servo is operated by engine vacuum via an electrically engaged valve triggered by a microswitch operated by the button in the head of the gear lever.


The part number is 3297631 or 3345087
Can anyone help?
Cheers
