Clutch Plate modification for Plus 2 S 130 5Speed
Posted: Sun Feb 24, 2019 6:39 pm
Having had the engine and 5 Speed gearbox rebuilt l thought it best to complete the jobwith a new clutch plate.
The existing clutch cover is Borg & Bech with an AP clutch plate which does seem to have plenty of wear left.
My enquiries about the appropriate clutch plate have revealed many comments about having to shave 5mm off the central spine shaft.
Unfortunately there dont seem to be any references about whether such reduction is applicable to a particular brand of clutch and there are mixed references as to whether the reduction should be off the Flywheel or the Pressure plate side. The original Lotus advisory l have seen seems to suggest a reduction to the flywheel side which doesnt seem right to me.
I have not seen any reference to how long the central spline shaft should be to ensure no dragging of the plate. I have a new Helix plate but on speaking to a Helix agent they advise having no knowledge of any need for such a modification. Maybe this would be the case if l bought a New Helix Pressure plate as well but l thought plates were interchangeable by brand. Having said that references to other Lotus Parts speciaists has also drawn a blank.
This seems to have been a subject raised on the forum in different guises over the years but l find there is little reference to specfic Plate Part Numbers and the required specification required etc.
Any specifics on the way to proceed would be appreciated.
