  3. Install the RH rocker arm assembly in the following sequence.
    1. Position the crankshaft with the cylinder number No. 1 approximately 155 degrees after Top Dead Center (TDC) by observing the crankshaft pulley dowel pin and clocking it to the 3:40 position (as viewed from the front of the engine).
    2. Determine which cylinder is actually in the firing position by observing the push rods for the No. 1 exhaust push rods should be raised 1.0 mm (0.039 in) and No. 4 exhaust push rods should be raised 1.5 mm (0.059 in). If the push rods are not in the correct position, rotate the engine one revolution clockwise (360 degrees).
    3. Install the rocker arm assembly as needed for the RH cylinder head (cylinder numbers 1, 2, 3 and 4). Tighten in 5 stages, in the sequence shown in illustration.
      • Stage 1: Verify that the top of the push rod engages the socket on each rocker arm.
      • Stage 2: Tighten to 4 Nm (35 lb-in).
      • Stage 3: Tighten to 8 Nm (71 lb-in).
      • Stage 4: Tighten to 13 Nm (115 lb-in).
      • Stage 5: Tighten a second time to 13 Nm (115 lb-in).
      • Repeat Stage 5, if any fastener moves more than 5 degrees in Stage 5.
  4. NOTE: Failure to install the oil spray bar in steps may result in damage to the oil spray bar.
