31. Verify gear-end axial clearance for both rotors. With gear-end up, rotate rotors so a feeler gauge
can be inserted between end of the rotor lobe and the inner surface of the bearing housing.
Clearance should be measured and recorded for all three lobes on both rotors.
Gear-end clearance: 0.005" min / 0.009" max
(when rotors are pushed to drive end)
Note:
Do not proceed with assembly if gear-end clearance is not correct! Refer to step 17 in Section
6 'Disassembly Instructions' to remove bearing housing. Repeat steps 23 through 31 making
necessary shim adjustments to achieve proper gear-end clearance.
32. Mount bearing retainer plate (15) onto gear-end bearing housing with eight bolts (17) and lock
washers (16). Reference FIGURE 9-8.
Torque: 40 ft-lbs
Figure 9-8 – RETAINER PLATE INSTALLATION
33. Rotate assembly vertical with drive-end on top
34. Apply AEON PD oil to drive and idler rotor bearing bores in drive-end bearing housing. Lubricate
internal surfaces and rollers of bearings with oil. Drain all excess oil from bearing before
installation. Oil should not be dripping from bearing in mounted position.
35. Install spherical roller bearing (13) by placing bearing over drive rotor shaft with identification
numbers facing up. Thread 3/4" pull rod into end of idler rotor shaft. Place bearing driver
EQ144211-1 over pull rod. Place a portable hydraulic cylinder over pull rod and onto driver tool.
Install 3/4" flat washer and nut onto pull rod and tighten against hydraulic cylinder. Press bearing
onto rotor shaft using hydraulic cylinder. Reference FIGURE 9-7.
Note:
Maximum load applied to threaded rod must NEVER EXCEED 5 TONS.
36. Repeat step 35 to install deep-groove ball bearing (12) on idler rotor shaft.
37. Verify drive-end axial clearance for both rotors. Rotate unit so gear-end is up. Rotate rotors into
a position so a feeler gauge can be inserted between the end of the rotor lobe and the inner
surface of the bearing housing. Clearance should be measured and recorded for all three lobes
on both rotors.
Drive-end clearance: 0.017" min / 0.025" max
(when rotors are pushed to drive end)
Note:
Do not proceed with assembly if these drive-end clearance is not correct!
38. Install key (36) into keyway on idler rotor shaft.
39. Thread 3/4" pull rod into end of the idler rotor shaft.
40.
Heat pinion gear to 350° F.
