Steering System: Pump: Pulley: Installation

CAUTION: Do not hammer on power steering pump pulley or pump shaft to install pulley. This action will damage pulley and power steering pump.

Place power steering pump pulley squarely on end of power steering pump shaft.

Place Installation Spacer, Special Tool 6936, on top of pump pulley. See Fig 1.

NOTE: Later build pumps feature a shaft with internal threads that are not as deep as earlier production, thus requiring a stack of washers, approximately 13 mm (0.5 in.) thickness, placed over Spacer 6936, before mounting Installer C-4063C on the pump. See Fig 2. To know if a replacement pump requires the stack of washers, measure the depth of the shaft hole. A later build pump will have a depth of 20 mm (0.78 in.) while an earlier build pump will have a depth of 32 mm (1.25 in.).

3 - STACK OF WASHERS

As necessary (see above note), place a stack of washers approximately 13 mm (0.5 in.) thickness over Spacer 6936. See Fig 2.
NOTE: When using Installer, Special Tool C-4063C, on this vehicle, use Forcing Screw C-4063-2.
Thread Installer, Special Tool C-4063C, completely into internal threads of power steering pump shaft, then rotate Installer Nut down against washers (as necessary) and Spacer on pump pulley.
Ensuring that special tools and pulley remain aligned with pump shaft, tighten Installer Nut, forcing pulley onto power steering pump shaft until Spacer comes in contact with end of pump shaft. When Spacer comes in contact with end of pump shaft, Installer Nut will no longer rotate.
Remove special tools from power steering pump.
Install power steering pump on engine. (Refer to STEERING/PUMP - INSTALLATION) .
