Rocker Arm Assembly (SOHC)

  1. Mark component location for reassembly reference. Ensure components are installed in original location. Disassemble rocker arm assembly. Inspect components for damage.
  2. Using "V" block and dial indicator, check runout of rocker arm shafts. Measure rocker arm shaft O.D. in rocker arm operating area. Replace components if measurements are not within specifications. See ROCKER ARM SPECIFICATIONS  table.
  3. Measure rocker arm I.D. and rocker arm shaft O.D. to determine oil clearance. Replace components if oil clearance is not within specification. See ROCKER ARM SPECIFICATIONS  table.
