Yes it is. Note in the drawing that the o-ring I specify, has a cross-section (thickness) of 0.157" and the OEM o-ring is 0.117". You are absolutely correct that the result is "greater compression" ( I prefer to call it proper compression) but the results would be increased differential pressure sealing capability. The stack height of the o-ring groove depth plus the compressed gasket thickness is only 0.004" less than the OEM o-ring cross section (thickness), putting only 0.004" compression on the o-ring, the same amount as an ordinary sheet of copy paper is thick.

The picture was taken after I ground the top edge of the shaft so as you can see, it does not take much grinding to get clearance required. I was thinking of grinding from left to right on the top edge of the shaft all the way to the first hole eliminating the step down on the shaft just after the first hole but that is not necessary. It could be either top edge, bottom edge or both top and bottom edges of the shaft you might grind depending where you need more clearance. I would install the canisters the correct way and then apply a vacuum to each and watch them as the shaft is sucked into the canister to make sure there are no issues. I actually have an extra vacuum pump I hot wired and connected to each canister but you can run a long rubber vacuum line (you can buy vacuum line by the 4-6 ft length very cheap from any auto parts store - get correct inside diameter) from your existing vacuum pump to each canister and hot wire your existing vacuum pump to get the same vacuum. Correct installation would be for this canister installed on the passenger side with the "749" up right as you see it. Or for those in the mid west.......North side of Z with Z facing West ![]() ![]() ![]() Last edited by Dynomite; 07-10-2010 at 10:55 AM. |
