The Guts of your servo

[volkenstein]

All,
  Since I'm in the mood and working on the spare parts, I've pulled apart the spare Servo to have a look.

Here's the shot :



The only suspect thing apart from a little rust, is just to the left you can see what looks like a "C" washer is in fact a hard paper gasket from the base of the adjuster and I'll be making an aluminium replacement and a smidge of gasgacinch to seal it.

Any questions....feel free.

Hiya volk,

Good shot of the beast disassembled!

For what it might be worth for anyone out there, rebuild kits (basically the rubber bladder) are available for around $20.00 US.

And volk, a helpful hint, paint one face of your long adjusting nut.  It really helps when you're under the car adjusting the clutch.  Makes it very easy to count your turns.

Mike,
      Red hot tip there! I'll be Rustbullet-ing it after cleaning/stripping so I'll use a bit to do the face.

Some additional info for people having a look....the big nut is 27mm and the eye bolt adjuster is left hand thread.


Thanks

All,
   Did the Rustbullet and paint. Here it is ready to for assembly.



I've laid the spring over one of the studs, making sure the whole bottom fit's inside those three captive nuts.

I did make an aluminium washer for the adjusting stud, 1mm thick, heavily chamfered on the inside diameter as the base of the stud is slightly tapered and coated it with Permatex. Did it all up after centering the diaphragm, and adjusted it as per "new clutch plate" measurements.

Next, drop that assembly into the front (bracket side) of the servo through the spring and it will sit quite neatly. I've just steadied the adjusting rod while I popped the rear section on, with the vacuum feed spigot at 90 degrees to the top two adjusters. NB!! Check the position of the small hole, top two studs and I rotated the diaphragm until the eyelet that connects to the clutch arm is parallel to the studs.



Whilst somehow clamping the two halves together, slip the retainer/clamp over the two halves joining lip, being very careful of the diaphragm rubber. I worked the rod in/out a few times to centre the diaphragm better, and tried to make sure the two halves were in line. Pinched the two clamp ends, put the screw and nut in and did it up a tiny bit then tapped around the outside to seat it better. Then do it up, don't go nuts...

Et Voila...



I took mike's advice and painted a Rustbullet strip on one face. To test is easy. Pull the rod out, put finger over the vacuum feed spigot and try and push in, or do the reverse......this one flat out refused to budge so it's into the parts storage bin.....
