    Rocker Arms/Shafts

    Print

    The rocker arms and shafts are an assembly; they must be removed from the engine as a unit. Always follow the torque sequence carefully when installing the rocker shaft assembly.

    1. Disconnect the negative battery cable.
    2.  
    3. Remove the cylinder head cover and bring the No. 1 cylinder to TDC.
    4.  
    5. Loosen the adjusting screws two turns at a time, in a crisscross pattern, to prevent damaging the valves or rocker arm assembly.
    6.  
    7. Unscrew the camshaft holder bolts and remove the rocker arm/shaft assemblies. Leave the rocker arm bolts in place as the shafts are removed to keep the bearing caps, springs and rocker arms in place on the shafts.
    8.  

    If the rocker arms or shafts are to be replaced, identify the parts as they are removed from the shafts to ensure reinstallation in the original location.

    To install:
    1. Lubricate the camshaft journals and lobes.
    2.  
    3. Set the rocker arm assembly in place and loosely install the bolts. Tighten each bolt two turns at a time in the proper sequence to ensure that the rockers do not bind on the valves. Tighten the camshaft holder bolts for 1984-91 to 16 ft. lbs. (22 Nm). For 1992-95 engines, tighten to the torque specified:
    4.  

    8mm bolts:

    D16Z6, D15Z1 engines: 14 ft. lbs. (20 Nm)

    D15B7, D15B8 engines: 16 ft. lbs. (22 Nm)

    6mm bolts:

    All engines: 9 ft. lbs. (12 Nm)
