No RV2 seal install experience but I would go ahead & replace it again as I dont think it will seal up on its own unfortunately

GM A6 compressor there is a replacement double lip rubber seal to replace original ceramic. Some say it is a good upgrade for leakers. Recently acquired but have not yet installed in 71 Vette. Couple questions: Are you saying I can put this seal in my Chrysler RV2 compressor? With ceramic, the seal to the shaft is fixed as opposed to rotating (friction?) with rubber lip. Does shaft design have to be considered? I like the idea and think it could work if the rubber seal OD will press into the bearing carrier where the original seals stationary half goes and the ID will seal properly to the shaft.

I like the idea and think it could work if the rubber seal OD will press into the bearing carrier where the original seals stationary half goes and the ID will seal properly to the shaft. Did not mean to imply that A6 lip seal would work in a Mopar compressor. Intention was to suggest that there may be a like product available for a RV2 unit. Check with this firm to find if such a seal exists for an RV2 as a good place to start looking http://www.phoenixmobileair.com/CompressorShaftSeals.aspx

This is what the factory RV-2 seal looks like. The rubber seal bottom center seals the shaft while the carbon seals seal to the outside.
I wonder if the new seals were lubed upon installation, dry carbon seals would probably fail early on.

I followed the installation procedure and positioned the shaft side down after putting oil in the compressor to lubricate the seal but is still leaks? I read a post that says to soak new seals in oil before installing them so I plan to do that when I install it.

From my 73 FSM, newest one I had with RV2 info.
Crankshaft Bearing Housing and Gas Seal Replacement (System Discharged) The gas seal may be replaced with the compressor installed in the vehicle or with the compressor removed and placed on a workbench. Special care should be taken when installing the new seal in a compressor mounted on the engine, that the carbon ring does not fall out of its housing. Adequate lubrication of the rotating seal assembly prior to installation on the compressor shaft, will prevent the carbon ring from falling out of place. If the compressor has been removed from the vehicle, it should be placed on its back, to facilitate seal replacement. It is necessary to seal the suction opening (back side) to prevent the loss of oil during replacement. The crankshaft gas seal replacement package consists of the crankshaft gas seal assembly and crankshaft bearing housing seal seat plate. Removal (1) Loosen belt, remove clutch, coil and drive key. (2) Remove crankshaft bearing housing seal bolts. (3) Remove bearing housing from crankshaft, using two screwdrivers inserted in the slots provided to pry the housing from the case (Fig. 12). (4) Remove bearing housing oil seal. (5) Remove gas seal plate and '0' ring from the bearing housing. This is part of the gas seal replacement package and must be replaced when the gas seal assembly is replaced. (6) Clean the front bearing housing thoroughly with mineral spirits. Installation (1) Immerse the new seal seat assembly in clean refrigerant oil and install in the bearing housing with the smooth (micro finish) side up. Use a sleeve with the minimum inside diameter of 1-3/8 inch to avoid damaging the micro finish sealing surface of the face plate. Tap the sleeve lightly until the seal seat is fully seated in the housing. (2) Before installing the cartridge-type assembly, inspect the assembly to make sure that the tangs of the carbon seal scallops and the retainer tangs are indexed in the slots of the respective mating parts (Fig. 13). (3) Immerse the seal assembly in clean refrigerant oil, carbon ring up. (4) Hold the seal assembly firmly at the outside edge, at the same time preventing the ring from coming out of position. Do not touch the polished sealing face of the carbon seal. (5) When the seal stop bottoms against the crankshaft bearing, inspect the indexing alignment again. Clutch key must be removed for seal installation. (6) Oil the new bearing housing oil seal and install. (Make certain that the seal is evenly stretched into position and that the seal is not rolled over). (7) Wipe the seal seat clean with a lint-free cloth, and re-oil with refrigerant oil. (8) Install the bearing housing, taking care to ensure that the "nose" of the crankshaft does not touch the seal seat in the bearing housing. (9) Insert 5, 1/4 x 20 screws and pull bearing housing squarely into position. This must be done 1/2 turn at a time per screw so that the ball bearing outer race will not be jammed by the bearing housing. Torque bolts 100 to 150 inch-pounds. (10) Replace drive key in shaft. (11) Assemble clutch to compressor and turn crankshaft by turning clutch armature. No more than 10 inch-pounds of torque should be required to turn crankshaft. If shaft is tight, remove clutch and loosen the bearing housing screws until shaft loosens up. Again, slowly tighten screws. (12) Check the oil level which should meet the requirements of Oil Level—Compressor. (13) Install clutch package on compressor, applying 20 ft-lbs. torque to tighten the clutch center mounting bolt. Install and tighten belts. Evacuate system and recharge.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
