CLEANING/INSPECTION:
.
Dry cleaning solvent P-D-680 (safety or Stoddard's Solvent) Is potentially
dangerous. Avoid repeated and prolonged breathing of vapors and skin
contact with the liquid. Do not use near open flame, arcing equipment, or
other Ignition sources. Always wear eye protection and protective clothing.
The flash point of P-D-680 Is 100°F to 138°F (38°C to 59°C).
Death or serious injury could occur if compressed air is directed against the
skin. Do not use compressed air for cleaning or drying unless the pressure
Is/has been reduced to 30 psi (2.06 bar) or less. When working with
compressed air always use chip guards, eye protection, and other personal
equipment.
1
Clean housing (2), gear wheel (6) and pinion (11) with dry cleaning solvent and dry with compressed air.
2
Inspect all components for damage or excessive wear. Replace any components severely damaged or worn.
INSTALLATION:
If either the gear wheel or pinion needs to be replaced, replace both. Timing
marks on the small pinion must be aligned with the keyway on the tapered
shaft. The timing marks on the gear wheel must be aligned with the mark on
the small pinion. Failure to heed this caution can damage equipment.
1
Slide pinion (11) onto camshaft. Install new lock washer (10) and hexagon nut (9) and tighten securely.
2
Install disc (8) into timing cover housing with graphite side of disc (8) facing outward.
3
Lubricate dry bushing in timing cover housing with grease (Item 3, Appendix B).
4
Install gear wheel (6) into dry bushing and secure gear wheel (6) with stud (7).
5
Install oil seal (5) and needle shell (4) onto gear wheel (6).
6
Fill housing (2) with 3-1/2 ounces (110 g) of warm grease (Item 4, Appendix B). Mount new gasket (3) and housing
(2) onto timing cover with four hexagon socket head cap screws (1).
