must be positioned so that the flat face of the seal neck
fits into the seal retainer component of the connecting rod
assembly. Apply a small coating of approved gear joint
lubricant to the inside surfaces of the seal.
3. Apply a small amount of lubricant to the flat face of the

seal (520).
4. Grease the concave spherical surface of the rear thrust
plate (320) and position thrust plate against the seal (520)
with the lip on the ou

5. Apply a film of grease to the splines on the inside of the gear
ball (300). Install gear ball on connecting rod (460), with
counter-bored end (end without splines) first on connecting
rod. Gear ball should slide freely against shoulder on
