    Typical example

  1. If necessary, follow Steps 1.a through 1.e in order to assemble the accessory drive.

    1. Inspect the condition of the teeth and the splines of gear (4) for wear or damage. Inspect bearings (3) and (5), circlip (2), and the front housing for wear or damage. Replace any components that are worn or damaged.

    2. Apply a small continuous bead of Tooling (B) to inner surface (X) of bearing (5). Place the gear shaft on a suitable support. Press on the inner race of bearing (5) until the bearing (5) is against the shoulder of gear (4). Remove any excess sealant.

    3. Apply a small continuous bead of Tooling (B) to inner surface (Z) of bearing (3). Place the inner race of bearing (3) onto a suitable support. Press the shaft of gear (4) into bearing (3) until the shoulder of the gear is against the bearing. Remove any excess sealant.

    4. Apply a small continuous bead of Tooling (B) to the outer surface (Y) of bearings (3) and (5). Place accessory drive housing (8) on a suitable support. Press the assembly of the gear into the accessory drive housing. Ensure that bearing (5) is against the front face of the recess in accessory drive housing (8). Remove any excess sealant.

    5. Install circlip (2) into the groove in accessory drive housing (8). Ensure that circlip (2) is correctly positioned in the groove.

  2. Lightly lubricate a new O-ring seal (7) with Tooling (C). Install the O-ring seal into the groove in accessory drive housing (8).

  3. Inspect the bore in the front housing for damage. If necessary, replace the front housing. Refer to Disassembly and Assembly, "Housing (Front) - Remove" and Disassembly and Assembly, "Housing (Front) - Install".

  4. Lightly lubricate bearing (3), bearing (5), and gear (4) with clean engine lubricating oil. Install the assembly of the accessory drive to the front housing. Ensure that the flange on the accessory drive housing is flush with the front housing.

  5. Apply Tooling (D) to allen head screws (1) and (6). Install allen head screws (1) and (6) to accessory drive housing (8).

  6. Tighten the allen head screws to a torque of 22 N·m (16 lb ft).

  7. Ensure that there is tactile backlash between the idler gear and the accessory drive gear.
