2. Oil Slinger/Spacer Removal and Gear Inspection
8. Remove the locknut (23), oil slinger (43), and gear
spacer (20) from the gear end rotor shaft using the
nut driver tool (T12).
9.
Remove the locknut (23), and gear spacer (20) from
the gear end second rotor shafts using the nut
driver tool (T12).
10.
Reinstall locknuts (23) on both rotors until fl ush
with end of rotor. This will keep gear from
shooting o
ff
of the rotor when pressurized.
11.
If it appears the gears can be reused their backlash
should be measured. Lock the idler rotor from turning
by wedging a shop rag between the tip of a lobe and
the air cylinder. Measure the backlash of the gears
using a dial indicator and a magnetic base. The
backlash should be measured in 3 places (every 1/3
turn). Permissible gear backlash is 0.001”-0.0045”.
12.
Match mark the gears by making small punch
marks on the ends of two meshing teeth.
