Installation Procedure

    Important: Do not attempt to fully seat the distributor using bolts or screws. If the distributor does not seat by hand, then it is not properly aligned with the camshaft.


    Object Number: 11488 Size: SH
  1. Install the distributor as follows:
    2. 1.1. Rotate the coupling until the camshaft sprocket pin slot aligns with the pin.
    1.2. Rotate the crankshaft until the engine is at the number 1 cylinder TDC. The camshaft sprocket pin is at the 9 o'clock position.
    1.3. Rotate the distributor distributor coupling until the camshaft sprocket pin slot aligns with the distributor base timing mark.
    1.4. Install the distributor.
    1.5. Slide the distributor onto the camshaft until the distributor is fully seated on the engine front cover.
    1.6. Install the distributor bolts.

    Tighten
    Tighten the distributor bolts to 12 N·m (106 lb in). Refer to

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
