Clutch Disengagement

Postby kfbrinton » Sun 06.05.2018, 19:32

I have a 69 Elan S4SE with no modifications. When the clutch petal is pressed in the clutch does not disengage until the petal is at the floor. When hot it does not completely disengage. I have bled the system and am relative confident there is no air in the line. I have somewhere heard comments about using a different master/slave combinatiion to move the clutch disengagement point. Any information along this line would be greatly appreciated.

Hi there kfbrinton.

Welcome to LEC . I hope you manage to find the answer to your issues. Most of the owners on here are of the 89 - 96 much later version on the Lotus Elan. Though there are a coupe of early Elan owners that may be able to help out.

Wrong Forum, this is for M100 Elans... I suggest you look at www.lotuselan.net/ ..or ..https://www.thelotusforums.com/forums/forum/409-classic-elan/

but you won't find either as helpful, well organised or friendly as this site. (Suggested solution : buy an M100 and use this site :lol: ).

On the theme of helpful ... on the clutch slave cylinder you'll find an adjuster nut and locknut on the rod to the release fork that alters it's effective length. Could be your locknut has come loose and let the rod become minimum length ..

Items 29 & 30 in the photo - from the parts manual for my Elan+2S

Adjust it (without the spring on) to get 2mm clearance between the operating fork and the adjuster nut (so the release bearing still has clearance or it will wear out by spinning all the time) ... and you should find the pedal works in the mid- position.

The diagram in the workshop manual is wrong. The clearance on the rod should be total play and not at the measurement points shown on the diagram.
