  1. Remove the engine from the vehicle. For additional information, refer to Engine .
    2. NOTE: Mark the location of the stud bolts.
  2. Remove the RH 6 stud bolts, 5 bolts and valve cover.

  4. If replacing rocker arms on the LH side, remove the protective covering from the LH cylinder head.
  5. Locate the dowel hole in the vibration damper.

  6. Rotate the crankshaft until the dowel hole is at the 12 o'clock position.
    • The No. 1 piston should be on the compression stroke. Wiggle the rocker on the No. 1 cylinder to verify both intake and exhaust rocker arms are able to move freely. If the intake and exhaust rocker arms do not move freely, rotate the crankshaft one complete revolution. You are now positioned to service the rocker arms for cylinders 1, 2, 7 and 8.

    NOTE: If servicing all rocker arms, or any of the rocker arms for cylinders 1, 2, 7 and 8, the remainder of this procedure must be performed before rotating the crankshaft to prepare the engine-to-service cylinders 3, 4, 5 and 6.
  7. If required, skip Step 8 and complete the rest of this procedure, for rocker arms on cylinders 1, 2, 7 and 8.
    8. NOTE: All service for cylinders 1, 2, 7 and 8 must be completed before rotating the crankshaft to prepare the engine to service cylinders 3, 4, 5 and 6.
  8. If not servicing cylinders 1, 2, 7 and 8 or if service to those cylinders has been completed, rotate the crankshaft one complete revolution to service the rocker arms for cylinders 3, 4, 5 and 6.
    • Complete the rest of this procedure for rocker arms on cylinders 3, 4, 5 and 6.
  9. Remove the crankcase-to-head tube(s).
    • Remove and discard the D-ring seals.

    NOTE: Only use hand tools to compress the valve springs. Do not use power tools or engine damage can occur.
    NOTE: If the rocker arm is severely worn, insert a small pry bar between the exhaust rocker arm and bridge to gain clearance by compressing the valves slightly.
  17. Install the Rocker Arm Service Tool plate on top of the bridges with the small point of the plate in between the exhaust rocker and bridge. Install the Rocker Arm Service Tool bolt and compress the valve springs until the plate contacts the top of the tool base.
