REASSEMBLY
1. Assemble input pinion/bearing
assembly, idler pinion/bearing
assembly, and output shaft/bearing
assembly.
2. Install output shaft oil seal into
gear box output half. Lubricate lip
seal.
3. Slide output shaft through lip
seal. Start output bearing in bore
in gear box output half. Position
idler pinion bearing assembly in
its bore in output half.
Simultaneously press both
assemblies into output half.
4. Install gasket on output half.
5. Position gear box input half; align
shaft bearings with bearing bores.
Press gear box halves together,
align pins in output half with pin
bore in input half.
6. Secure halves together with
twelve bolts.
7. Slide input pinion/bearing
assembly into bore in gear box
input half. Rotate pinion during
installation to make sure gear
teeth align with internal spur gear
teeth.
8. Install O-ring (Ref. No. G25) on
outside of pinion bearing.
9. Reassemble gear box to pump
base with four bolts.
10. Reassemble adapter to gear box
with four bolts.
