Installing all of the assy drives.

I installed the vac pump, gov drive, and fuel pump today. I tried to see if the fuel pump diaphragms were ethonal compatible but Tempest says they are not. I looked for the marine version of this style of pump thinking someone has already figured this out but I came up with nothing. I installed the pump now anyways because it is easy to get at and you can see what you are doing. The pump bolts are hard to get started and you have to have a octopus to hold all of the things that need to be held to get it installed. Why some one has not come up with a little bit of a different mounting style is beyond me. You have to install the bolts thru the pump first. Then you get the gasket down and in place. You then set the pump down in making sure the arm gets on top of the plunger in the assy case. You have to hold the pump away from the case about 1/4" so that the bolts go in straight. Make sure the fuel pump gear lobe is at the highest postion so there is very little spring pressure to overcome on the fuel pump arm. Once you get the bolts started you then tighten it down evenly making sure the arm does not come off to one side. It's easier to do it when the engine is upright and the oil sump is off. I change one on my RV-6 with the engine on it was a major job. I was almost to the piont of yanking whole engine off to get at it. I ended up having to do it twice because of the gasket not seating correctly and I had a small leak on the back of the engine. The govenor and vac pump drives are straight forward. Just pay attention to how the spacer washer is supposed to go and the vac pump gets a seal on the outside as the gov does not because you have a seal with the gaskets to get oil to the drive shaft. You can't interchange the drives since they are different sizes and lengths. I got all the bolts/nuts torqued and then I safetied wire the fuel pump bolts. DO THIS NOT WITH THE MAGS OFF. It's much more easier to get all the wires.
