Death or serious injury could occur if compassed 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 com-
pressed air, always use chip guards, eye protection, and
other personal protective equipment.

the small pinion. Failure to heed this caution can damage
equipment.
Slide pinion (11) onto camshaft. Install spring washer (10) and hexagon nut (9) and tighten
securely.
Install disc (8) into timing cover housing with the graphite side of disc (8) facing outward.
Lubricate dry bushing in timing cover housing with MIL-G-10924 grease.
