Camshaft Timing & Belt Replacement: Installation

  1. Starting at the crankshaft install new timing belt over cogged sprockets in a counterclockwise direction. Keep belt span from crankshaft to camshaft tight as belt is installed over remaining sprockets.
  2. Loosen belt tensioner bolt about 1/2 turn and allow tensioner to snap against belt. Then tighten one of the tensioner bolts.
  3. With the crankshaft pulley installed, hold pulley stationary and tighten pulley attaching bolts. Rotate crankshaft 2 complete revolutions and ensure timing marks are aligned.
  4. Hold crankshaft from turning using wrench T81P-6312-A (or equivalent). With camshaft held, turn cam sprocket counterclockwise, using holding tool (D81P-6256-A or equivalent) and a torque wrench. When torque on cam sprocket reads 27-32 ft. lbs. (37-44 N.m) for new belt or 10 ft. lbs. (14 N.m) for a used belt, tighten belt tensioner attaching bolts.
    NOTE: Do not apply torque to camshaft sprocket attaching bolt. Apply torque to hex on sprocket.
  5. When valve timing is correct, crankshaft keyway should point to 12 o'clock position and camshaft to 6 o'clock position. See Fig. 10.
