5.3.9 Compressor Oil Seal and Retainer
a) The compressor oil seal retainer [26] (picture to the right) is
located inside the motor spacer [600] and mounted to the
crank case [1] of the compressor with six bolts [28]. It can be
taken off by loosening and removing the bolts and pulling
toward yourself. If it can hardly be taken off because of the
sticking gasket, slightly hitting it with a soft face hammer will
allow you to remove it.
b) The compressor oil seal [32] is inserted inside the oil seal
retainer. As long as no fault is found in the lip part (in contact
with the shaft), the compressor oil seal need not be taken
off.
When replacement of the oil seal is required, remove the four bolts [32-2] that are tightening the
compressor oils seal gland [32-1] (following picture to the left), and take off the oil seal gland.
c) To remove the compressor oil seal, while allowing the edge of
a flat blade screwdriver to hit on the slightly exposed part of
the inner circumference of the oil seal through the shaft hole
of the oil seal retainer, hit the head of the screwdriver with a
hammer to push out the oil seal (picture to the right).
While changing the hitting position of the screwdriver little by
little, gradually push it out.
● The oil seal, once it is removed, it is deformed and consequently cannot be used
again. If the seal is removed, replace it with a new one.
