How is the pivot pin fitted into the bellhousing? I want to use one from a 4 speed into a 5 speed; are they different? cheers!

From memory,yes,I seem to remember a "blade" as opposed to a round pivot but I could be confusing with eclat box?
I think you will have to fit the four speed pivot into a metric (the size escapes me at the moment) bolt..

AussieJohn,
If you need to find out if Elan and +2 parts are the same (or different) and the respective Parts manuals are not to hand,
then try Paul Matty's website and download or view his parts list online.
Chances are that if his catalogue shows the same part number, they'll be interchangeable.
Regards,
Stuart.

Thanks guys; John, do you recall if they are a press fit in the 4 speed? It seems to line up with a bolt hole in the 5 speed, so I thought it might be threaded. I have tried to remove the 4 speed one with vice grips but no luck; cheers.

Sorry John,can't remember, but,do remember that you can use the 4 spd clutch pressure plate and bearing-you do need to open up the bearing carrier to fit over the input sleeve and "relieve" the ali housing where the fork sits,as for the clutch plate -that has to have the larger splined middle..

The pivot piece is pressed into the iron housing on the 4-speed. On the new housings I had cast, I made provisions for the use of the existing pivot. Just punch out the one from the iron housing and press it into the new one. Just make sure the new hole is of the correct diameter to secure the pivot when it is pressed in place. Or, if you have access to a lathe, just copy the existing piece.

Reviving an old thread...
I had been battling clutch problems for a while, pulled the engine and have determined that:
Installed in the car was a non-Lotus, flat-faced throwout bearing pressed onto a round-faced bearing hub such that there was no pilot protruding from bearing hub to locate it concentrically with the pressure plate platen. It's no wonder the clutch was eating itself; will detail the problem in another thread.
So, I now have a correct flat-faced throwout bearing hub, flat-faced bearing and platen-type pressure plate ready to install into the car. My question is in regard to the length of the clutch fork pivot bobbin pressed into the bellhousing.
Simply, is the fork pivot bobbin height different for a flat-faced hub/bearing/pressure plate assembly vs. a round-faced hub/bearing/pressure plate assembly?
