1600M servo dimensions

[sonnylad]

Can anyone confirm the dimensions for original servo fitted to the 1600M, replacements seem to be an inch in diameter smaller unless mine had been previously changed.

I though they were all TR6 (booster and master cyl) ??

So did i, but after getting this:

it appears the new one's are being made smaller, unless mine was never TR6 to start with.

Weird as my my brake master cylinder is definatly TR6

So with side by side comparison there a huge difference, will this help someone recognize the original fit

I fitted the same servo - you photos could have been mine the old one was in a real state too and full of fluid for years. Fitted and works perfectly.
Your sandwich plate is timber though? Mine was ali.

Did you notice the smaller diameter when you changed over to the new one ?

Yes it was smaller. Looks great fitted!

Ok thanks for confirming that, guess i shall just have to fit and try it out.

Yep got myself an original TR6 ali plate but having approx 3mm skimmed off it as it's a little too thick

[sonnylad]

Plate was 20mm thick so meant the studs came up too short for bolting the accelerator plate back on.

This was due to adding a closed cell foam either side to make waterproof, so removing 3mm will allow for them to be fitted and then squash right down.

Ok the back of fibre board originally had a thin foam style gasket so was just copying that.
