Power Divider
Pump Assembly
Use these instructions with the carrier assembly in or out of
the vehicle.
If the unit does not have a pump, go to the Power Divider
Assembly section.
Note: Keep work area clean. Dirt is an abrasive and will cause
premature wear of the otherwise serviceable parts.
Note: For non-pump models, see page 17 for output side gear
seal manifold installation.
Note: Only service the power divider if the differential carrier
is secured in a stand or while the axle is still attached to
the housing.
During installation of power divider cover, the inter-axle
differential (IAD), input shaft assembly or IAD shift system
parts may fall from the carrier if not careful. Use caution to
prevent injury or damage.
1. Install the pump into the output side gear so that the
pump shaft is facing toward the teeth end of the side
gear.
2. Install the pump locking dowel pin into the hole in
the output side gear hub. Make sure the pin is lined
up with the machined slot in the pump body.
