5. Repeat steps 1 through 4 for remaining piston ring carriers, also for idler (short) rotor.
6. Install piston rings (10) into the piston ring carrier on gear-end and drive-end of both rotors, one at a time,
starting with ring closest to rotor body. Ensure ring ends are hooked together properly. Position ring end gaps
180° from each other.
7. Install bearing housing inserts.
7a. Place drive-end bearing housing (4) in a horizontal position in a hydraulic press with air side surface
facing down.
7b. Apply a small continuous bead of Loctite 620 to insert mating face and through bore I.D. in bearing
housing as shown in FIGURE 7-3.
7c. Apply a continuous bead of Loctite 620 to bearing housing insert edges as shown in FIGURE 7-4.
7d. Place an insert (7) in one of the insert bores in the bearing housing with drilled ports closest to air side of
the bearing housing.
7e. Orient inserts with drilled ports in 12:00 and 6:00 o
’clock positions as shown in FIGURE 7-5.
7f. Using driver tool EQ144211-3, press insert into bearing housing. Verify it does not extend beyond the air
side surface of the bearing housing.

8. Install a retaining ring (8) into groove in bearing housing by inserting one end into groove while pushing down
around the circumference until the entire ring is in groove. Reference FIGURE 7-5.
