Figure 28 Grease Fittings for Pin Crank Bearings
Replace Tip Seal
Note:
The grease fitting located in the center of the pin crank bearing feeds only the orbit scroll side
bearing. Use a needle adapter to supply grease to the housing side bearing. Pump grease gun to
eliminate any air in the needle adapter. Hold grease gun for 5 to 10 seconds after feeding grease to
prevent grease blowback from the grease fitting.

2
Remove the six housing nuts (see figure 27).
3
Remove the stationary scroll housing.
4
Remove the old tip seals from both the orbiting and stationary scroll housings.
5
Remove the old dust seals from both housings.
6
Blow off any dust from both housings.

Install the new high pressure (shorter one) tip seal starting from the center of the scroll, outward
inside the seal channel.
Note:
The side and bottom lip notches of the tip seal face INWARD and DOWNWARD in the
channel.

Install the new low pressure (longer one) tip seal in the same way.
Note: Make sure there is no gap between the high and low pressure seals.
