b. Cleaning, Inspection, and Repair.

(1) Wash all of the power take-off parts (except th clutch facings or shielded bearings) in cleaning solvent

(item 4, Appendix C), then dry them with compressed air.

WARNING

Do not breathe cleaning solvent P-D-680 vapors for long periods of time or use solvent near open

flames. To avoid illness, explosion, or fire, only use solvent in well-ventilated areas away from open

flames.

Use the recommended air pressure (under 35 psi line pressure) when using compressed air to clean

components. Too much air pressure can rupture or in some way damage a component and create a

hazardous situation that can lead to personnel injury.

(2) Examine the ball and roller bearings for corrosion and pitting. Lubricate each bearing with light engine oil

(item 8, Appendix C); then, while holding the inner race or cone from turning, revolve the outer race or cup

slowly by hand and check for rough spots.

(3) Examine clutch facing for wear, burning, or scoring. Also, check the teeth for wear or damage. Replace

clutch facing if the teeth are worn or damaged, or if the facing is badly burned or worn.

(4) Inspect the friction surfaces of the inner, center, and outer clutch pressure plates for being flat, smooth,

and free from cracks or heat checks. Also, examine the drive bosses, the keyway in the outer pressure

plate, the adjusting ring threads, and the notches in the inner pressure plate.

(5) Examine all of the release levers, link pins and pin holes in the links, release levers, release sleeve, and

pressure plate for wear.

(6) Inspect the clutch adjusting ring wear plate and threads for wear. If the wear plate is worn excessively,

reverse the plate. If both sides of the plate are worn excessively, replace the plate.

(7) Examine the wear surface of the clutch release sleeve collar and the mating surface on the release sleeve

for wear and scoring.

(8) Inspect the mating surface of the clutch release yoke fingers and mating trunnions on the release sleeve

collar for wear.
