Figure 9-4 – ROTOR INSTALLATION (MECH. SEAL)
17. Using a depth micrometer, measure and record total rotor to bearing housing end clearance for
each rotor. This is accomplished by measuring distance from top edge of air cylinder to top of
rotor lobe while rotors are in vertical position.
18. Install two dowel pins (34) into gear-end of air cylinder.
19. Orient gear-end bearing housing so dowel holes align with dowels in air cylinder and mount
bearing housing onto air cylinder.
20. Fasten gear-end bearing housing to air cylinder using two socket head bolts (29) in counter bored
holes in the bearing housing. Carefully draw down bearing housing as not to damage piston
rings. Tighten bolts.
Torque: 40 ft-lbs
21. Install mating ring of mechanical seal assembly (43) onto rotor shafts. Reference FIGURE 9-5.
Note
: Ensure chamfer on rotor shaft is smooth. Sharp edge can cut o-ring of mating ring during
installation!

22. Thread 3/4" pull rod into end of rotor shaft. Place slinger driver EQ144211-3 over pull rod. Install
3/4" flat washer and nut onto pull rod and using a 3/4" wrench, draw mating ring on rotor shaft.
Ensure each mating ring is seated firmly against mechanical seal spacer. Repeat for opposite
rotor.
23. Place false bearing assembly EQ144211-5 over idler rotor shaft and into bearing bore. Place
false bearing spacer EQ144211-10 over shaft and install locknut. Tighten locknut by hand using
locknut socket EQ144211-2 to ensure mechanical seal mating ring is firmly against mechanical
seal spacer. Reference FIGURE 9-6.
