Lockheed servo

PostPost by: davidj » Mon Apr 21, 2014 7:47 pm

Good afternoon,

I am going to have to replace the girling servo on my +2. The final straw was brake fluid in the air vent (!).

Has anyone pictures of the lockheed unit fitted in the +2 they can please send me, single circuit brakes, as I am going to have to modify the mounting.

Salut David

Here's a picture:

And another:

I think the white air vent should be pointing up within a certain degree described in the installation instructions. Not the case in the second photo but there were no braking problems.

The Girling looks nicer IMHO but is expensive to rebuild unless you do it yourself.

The white valve should be pointing downwards, at least 30 degrees below the centre line and as per the second photo.



Having said that, my Lockheed/Delphi servo was mounted correctly and sometimes used to stick on at braking. The bore diameter on that valve is very small and this contributes to it sticking. In the end I gave up with it and reverted back to the Girling unit (fully refurbed)

Here's mine, orientated front to back. Looks like it's attached to the original Girling bracket with an adaptor plate (I didn't originally fit it). I did plumb in a 'U' bend in the vacuum pipe though, as recommended in the installation instructions.
