  1. Bring No. 1 cylinder to top dead center (TDC) on compression stroke by turning crankshaft until crankshaft pulley is aligned with timing mark '0'.
  2. Check rocker arm shaft bracket nuts for looseness. Using sequence shown in Fig. 19, torque rocker arm shaft brackets 1 through 8 to 16 ft. lbs., then brackets 9 and 10 to 6 ft. lbs.
  3. Check for play in No. 1 intake and exhaust valve pushrods. If No. 1 cylinder pushrods are depressed, rotate crankshaft 360°to position No. 1 cylinder on compression stroke.
  4. Adjust the following valves:
    1. No. 1 intake and exhaust.
    2. No. 2 intake.
    3. No. 3 exhaust.
  1. Rotate crankshaft 360°and adjust the following valves:
    1. No. 2 exhaust.
