A spray bottle lled with clean compressor oil
may be used to lubricate the faces of the seals
without touching the seal.
E) Install a new O-ring on the seal cover, making
sure the O-ring is placed in the O-ring groove
and not the oil gallery groove. Lubricate both
seal faces with clean compressor lubricating oil.

mended torque values.
