Rocker Arm Assembly: Removal

  1. Rotate engine until mark on crankshaft balancer is at 2 o'clock position, or until timing mark on crankshaft damper aligns with "0" mark on timing tab. Rotate crankshaft counterclockwise 3 1/2" (88 mm). Estimate this distance by aligning crankshaft damper mark with first lower water pump bolt, about 12:30 position. See Figure. Remove intake manifold. See INTAKE MANIFOLD . Remove fuel injection lines and valve covers.
  2. Remove rocker arm shaft bolts and rocker arm shaft. Mark component location for reassembly reference. To disassemble rocker arm shaft, see VALVE TRAIN  under OVERHAUL.
  3. If removing push rods, note paint stripe on hardened end of push rod (end closest to rocker arm). If no paint stripe is present, mark hardened end of push rod for reassembly reference.
  4. Insert a screwdriver into valve rocker arm shaft bore and break off end of nylon valve rocker arm retainers. Remove valve rocker arm retainers with a pair of pliers. Slide valve rocker arms from shaft.
