INSTALLATION OF NEW DRIVE GEAR
NOTE: If drive gear must be replaced, it is recom-
mended that the oil pump be inspected for operating
smoothness; plastic bearing, bronze bushing and oil
pump drive shaft be inspected for wear, gauling or
damage. Replace parts as required.
1. Align drive gear halves on crankshaft with retain-
ing screw access holes towards center main
bearing.
2. Clean retaining screw threads with Loctite Primer
T (92-59327-1). Apply Loctite 680 (obtain locally)
to screw threads.
3. Secure drive gear halves together with retaining
nuts and allen screws. Torque screws to 8 Ib. in.
(1.0 N·m).
4. Check gear halve split lines. Split should be
drawn tight together (zero clearance) if gear
halves are properly installed.
CAUTION
Gear tooth mismatch at split line must not exceed
0.020 in. (0.50mm) or gear failure will result.
