Section 1.9.2
Front Crankshaft Seal Wear Sleeve Installation

Perform the following to install the front crankshaft seal wear sleeve:

  1. Clean the seal wear sleeve seat area on the crankshaft.

    NOTICE:

    Be sure to heat the new seal wear sleeve as evenly as possible. If available, an oven should be used. Uneven heating of the seal wear sleeve can weaken the material and reduce the service life.

  2. Install the seal wear sleeve with the rounded edge toward the inside of the seal wear sleeve installer tool (J–47271, part of toolset J-47273). Heat the tool and sleeve together in an oven to a maximum of 150°C (302°F).
    warning

    BURNS

    To avoid injury from burning, use lifting tools and heat-resistant gloves when handling heated components.‪

  3. Remove the tool and sleeve from the oven and thread driver handle (J–8092, part of toolset J-47273) into the seal wear sleeve installer tool (J–47271, part of toolset J-47273).

    NOTICE:

    Ensure that the rounded edge of the seal wear sleeve faces out and is flush with the crankshaft. The installer tool guarantees the seal wear sleeve position onto the crankshaft. Failing to use the correct tool may affect the service life of the seal.

  4. Drive the seal wear sleeve onto the front of the crankshaft.
  5. Wait until the seal wear sleeve cools to room temperature before installing the oversize radial seal. Refer to "1.7.2 Front Radial Seal Installation" to install the front oversize radial seal.
