Correct positioning of Lockheed servo.

[M.J.S]

This is very confusing, and a little annoying.

This week my +2 was with a Lotus specialist, setting up the carbs and ignition, plus another few bits and pieces. He informed my that the Lockheed servo; likely a later replacement before my ownership, was fitted at the wrong angle. I requested he alter it, which he duly did (and I certainly paid for the adjustment in the large bill).

The way it was positioned, the air control valve was facing upwards and the hydraulic slave cylinder was pointing upwards also. I have before me an old installtion guide I downloaded.

It states the air control valve should be situated at least 30% below the centre line, and ther hydraulic slave cylinder outlet inclined upwards between 25 and 45 degrees for the horizontal plane.

I have looked at as many Elan+2 underbonnet pics that I can find with Lockheed servos, and these and other diagrams I see confirm the above.

The specialist however, has pointed the slave cylinder downwards (the complete opposite to what the guide says - I believe it was correct as it was) and has not altered the upward angle of the air control valve which was, and remains, incorrect.

I'm not ranting. The man has a good reputation and a workshop full of classic Lotus and other classic performance cars, and there were other faults with the car he spotted immediately that I never would. Perhaps it was heat induced brain fade? I am merely an enthusiast and owner, but I think he is wrong.

I believe the correct way, based on all I see, is to tip it back upwards the way it was, the slave cylinder at about 35 degrees, and twist it so the air control valve is facing downwards.

Please enlighten me gents. Thanks.

I placed the servos on my twin circuit +2 on the fender and in the nose. See photos.

This is how Paul Matty fitted my one. Jim

The manufacturers instructions are correct,helps with bleeding the air through the servo,and valve....
