Step 16
Install lower input shaft roller bearing race into the top of the bearing plate (102) so it
locates against the lube pump (A160).
Step 17
Install the sump tube (173) into the sump tube fitting (944C).
Step 18
Install input shaft assembly (A120) into lower input shaft roller bearing. Pull up on the
idler shaft (A140) approximately 1.0” to 1.5” and mesh the input shaft assembly (A120)
gear with the idler shaft (A140) gear. Make certain that the input shaft assembly (A120)
slot fits over the lube pump (A160) drive pin.
Step 19
Freeze upper idler journal bearing (151D) in dry ice for 1/2 hour. Install the upper idler
journal bearing (151D) into the upper gearbox housing (101B). Use socket head cap
screws (905AB) to secure the upper idler journal bearing (151D) to the upper gearbox
housing (101B).
Step 20
Install the lube jet (174D) into the upper gearbox housing (101B).
Step 21
Install the upper gearbox housing (101B) onto the bearing plate (102).
Step 22
Install alignment bolts (909C) and fasten gearbox housings together. Use specified
torque value from chart, see Table 8.1.
Step 23
Install fasteners (909B) into gearbox housing and tighten. Use specified torque value
from chart, see Table 8.1.
Step 24
Install input seal (115) over input shaft assembly (A120) and press into upper gearbox
housing (101B), seating the input seal (115) firmly against the locating shoulder in the
upper gearbox housing (101B).
Step 25
Turn the complete gearbox assembly over so the high speed shaft (A130) is pointing
vertically toward the ceiling.
Step 26
Install the rotating face (51D) over the high speed shaft (A130) with the chamfer in the
rotating face (51D) toward the high speed shaft shoulder (A130).
Step 27
Install the roll pin (918D) into the lower gearbox housing (101A). Use a soft mallet to seat
the roll pin (918D) into place.
Step 28
Install the gearbox seal (60C) and the o-ring (936P) onto the lower gearbox housing
(101A). Use socket head cap screws (905E) and lock washer (916A).
Step 29
Install o-ring (936H), upper process seal (60B), into seal housing (30).
Step 30
Install rotating face (51D) onto high speed shaft (A130).
Step 31
Install o-ring (936K), sleeve (50B), onto high speed shaft (A130).
Step 32
Install o-ring (936J).
Step 33
Install thermal barrier gasket (87A) onto seal housing (30).
Step 34
Install seal housing (30) onto lower gearbox housing (101A).
Step 35
Install hex head cap screws (905A), lock washers (154AT), flat washers, (916AG), seal
washers (916S), through seal housing (30) and tighten screws to specified torque value.
