Has anyone fitted a remote servo to a 72-74 bay?

  1. More pics... The 4 M6 mounting holes are either side of the seat base. 2 just in the walkway and 2 under the seat. I used the pipe clip bungs in the walkthrough as a guide for measuring. As you can see they are 19.5 cm from the middle of the 3 pipe clip bungs. Take care as they are not all in line.

    The rear most side of the servo serves the FRONT brakes. The side nearest the beam, serves the REAR brakes. The ends are the outlets. The feeds from the master cylinder go into the TOP of the servo, between the canister and the bleed nipples. These unions are all 3/8 UNF 24 TPI pitch, LONG unions. (you MUST get the correct ones). They should screw in easily, by hand. Access for a spanner to tighten up the feeds from the master cylinder is tight so get hold of a short 11mm spanner if you can.

  4. THese spacers were made to take up the gaps created by the floor mouldings under the mounting bracket. I made 6 but only needed 4. It is just 20mm X 3mm aluminium bar with 6mm holes. I used the bracket as a template. A good tip for drilling the bracket holes is to make a card template.

  5. Could you mount it on the other side and keep the heater hose? Can't be bothered to look under my van ;)
     
  6. I tried that. There is not enough room. The conduits for the control cables are in the way. I am going to look into a way of re plumbing in the main cabin heater, but it will mean fabricating some sort of adaptor; to get the 57mm hose round the radiuses. I tried EVERY location, this was the only place it would go. You could mount it much further back under the floor. I wanted to keep the amount of brake line to a minimum. The handbrake cables also have a big impact on where it will go. You don't want the cables rubbing on the servo canister.

  9. This is the vac hose routed under the van. It is cable tied up and covered in plastic cable wrap. Everywhere it goes through drillings, I have used rubber grommets.

    If you look on the RHS of this picture, you can just see all the conduits for the control cables that prevent you mounting the servo on the other side of the floor. you could of course mount it in the area between the cross members. you would just need to drill through the load bay floor. I didn't want to lift my floor as it would have been a big job.

  10. I just need to get on with the job I always put off now. brushing back, rust proofing and re stone chipping the underneath of the van. The van is rally solid underneath but needs re protecting as you can see.

  12. Snotty, can you please re post your picture of how you drilled and tapped your manifold. I want to put it in my how to.

    cheers.
     
  13. Manifold, or rear frame for the vac pipe?
     
  14. the manifold please.
     
  15. Here's a pic of the barb I fitted. It's 1/4" NPT, which gives a barb OD of 1/2" for the vacuum hose. Once the engine was back in, I realised it's pointing the wrong way: towards the front of the van. Duh. I'll need to change it for a 90º fitting, so that it points outwards toward the hose hole.

  16. Thank you
     
  17. No prob. I'll expect a signed First Edition of your thesis ;)...
