Help! RV2 compressor blew new shaft seal

HI,

Is the system still holding R-134A and pressure? If so maybe just too much oil. An empty RV-2 system should be filled with about 10 OZ of oil. If the seal totally blew you will have lost the R-134A also. The problem now is to do anything you will have to recover the R-134A if it is still in there. Look in the factory service manual and it will show you how to make up a small dipstick and measure the oil level. The system must be discharged to do this.

Past that, I would replace the seal. As others have mentioned you can't touch the seal surfaces and handle them only on the edges. I also soak them in a container of oil over night before installing. You can replace the seal with the compressor mounted on the engine but, it is much more difficult to make sure things don't get off on an angle putting it together. It's better to have the compressor off and lying on its back. Check the shaft surface for smoothness and when you place the nose piece back in needs to be straight level and the bolts torqued down slowly and evenly side to side so the nose piece doesn't get cocked. The nose piece o ring should be coated with oil also.
