REMOVAL

CAUTION

Keep all second clutch parts together. Intermixing second clutch

parts with any other clutch parts will cause damage to

second clutch backplate (1) from transmission (5).

CLEANING AND INSPECTION

WARNING

Compressed air source will not exceed 30 psi (207 kPa). When

cleaning with compressed air, eyeshields must be worn. Failure to

wear eyeshields may result in injury to personnel.

Volatile mineral spirits burn easily and fumes can explode. Do not

smoke or allow flames nearby when using volatile mineral spirits.

Failure to do so may cause serious injury or death to personnel.

1. Clean all second clutch parts with mineral spirits and dry with a lint-free rag.

2. Inspect internal-splined clutch plates (4) and external-tanged clutch plates (3) for burrs, scratches,

cracks, breaks, and scores. Replace clutch plate(s) (4) or (3) if burred, scratched, cracked, broken, or

scored.

3. Measure thickness of internal-splined clutch plates (4). Replace internal-splined clutch plate(s) (4) if

thickness is less than 0.090 in. (2.29 mm).

4. Place external-tanged clutch plates (3) on clean, level surface. Measure distance from inside

diameter to level surface. Replace external-tanged clutch plate(s) (3) if distance is more than

0.010 in. (0.25 mm).

5. Inspect second clutch backplate (1) for wear, burrs, scores, scratches, and breaks. Replace second

clutch backplate (1) if worn, burred, scored, scratched, or broken.
