Cummins N14 STC, Celect, Celect Plus – Service Manual 009-005   Accessory Drive Pulley Wear Sleeve

After the seal has been removed, position the wear sleeve removal tool, Part Number 3824452, on the accessory drive wear sleeve so that the rounded end makes contact along the entire wear sleeve and tap with a hammer until the sleeve loosens.

NOTE: The wear sleeve will

not
break open but will loosen to allow removal.

Remove the sleeve.

If the oil seal wear surface on the accessory drive shaft is mutilated or has a groove worn deep enough that it can be felt with a fingernail, a wear sleeve

must
be installed.

Accessory Drive Shaft Wear Sleeve (if required) Installation Replacement:

Clean the shaft where the wear sleeve is to be installed.

Remove dents or burrs if present.

Screw the inner portion of the pusher tool, Part Number 3376085, onto the end of the accessory drive shaft.

Place the wear sleeve to be installed in position. Install the seal/wear sleeve installation tool, Part Number 3824451, on the shaft against the wear sleeve with the small end toward the wear sleeve. Screw the outer portion of the pusher tool, Part Number 3376085, on the inner portion. Tighten until the installation tool touches the end of the shaft.

NOTE: Make sure the wear sleeve is square to the installation tool at the start and maintain squareness as the wear sleeve is being pushed.
