CAUTIONDO NOT rotate crankshaft or camshafts with timing belt removed and cylinder heads installed.
CAUTIONCamshaft timing belt must be replaced if cylinder head is to be removed or if drive gears, tensioner or coolant pump are to be replaced. Camshaft timing belts must be stored and handled with care. Always store a camshaft timing belt on its edge with a bend radius greater than 2.0" (50 mm). DO NOT use a camshaft timing belt that has been twisted or bent double, as this will damage reinforcing fibers. DO NOT use a camshaft timing belt if debris other than belt dust is found in timing belt covers. DO NOT use a camshaft timing belt if partial engine seizure has occurred. DO NOT reuse a camshaft timing belt if mileage exceeds 45,000 miles. DO NOT use an oil or coolant contaminated timing belt (cause of contamination must be rectified).

Installation

Note. Following front or rear timing belt installation, it is possible that, after rotating engine and positioning crankshaft pulley to SAFE position, the timing marks on rear timing gears may be misaligned. This misalignment is acceptable provided that the timing belt installation procedure was carried out correctly.

  1. Clean camshaft gears and hubs, crankshaft gear, tensioner and water pump pulleys. Install hubs to camshaft gears and install gears to camshafts. Install NEW bolts and tighten sufficiently to allow gears to rotate without tipping.
  2. Position timing belt to crankshaft gear. Install tool LRT-12-197 into each exhaust camshaft in turn. (Scheme 17) Using assistance, rotate each exhaust camshaft slightly clockwise and align timing marks on left and right rear camshaft gears. (Scheme 18) Remove tool LRT-12-197 from exhaust camshaft. Install tools LRT-12-175 to left and right rear camshaft gears.
  3. Rotate both front intake camshaft gears fully clockwise as viewed from front of engine. Using fingers only, install front timing belt to gears, starting at the crankshaft gear and working in a counterclockwise direction. Keep belt run as tight as possible and turn camshaft gears only a minimum amount counterclockwise to install timing belt.
  4. Position an Allen key in tensioner backplate and hold tensioner pulley against timing belt. (Scheme 19) With assistance, position tensioner, install NEW Patchlok bolts and tighten to specification. See «TORQUE SPECIFICATIONS»(ref-159181-S03504048662003111700000). Remove tools LRT-12-175 from rear timing belt gears.
  5. Install tools LRT-12-196 to intake camshaft front gears and into end of each exhaust camshaft. (Scheme 16) Tighten front intake camshaft gear bolts in 2 stages to specification. See «TORQUE SPECIFICATIONS»(ref-159181-S03504048662003111700000).
  6. Remove tools LRT-12-196 from both intake camshaft gears and exhaust camshafts. Remove wedge from between drive belt and oil pump belt guard. Remove 1.5-mm diameter pin from tensioner. Install rubber blanking plug around tensioner. Remove timing pin LRT-12-232.
  7. Clean exhaust camshaft front cap seal locations and install NEW cap seals. Position engine front mounting plate and maneuver plate into position. Install bolts but DO NOT tighten at this stage. Install bolts securing front mounting plate to cylinder block and Intermediate Reduction Drive (IRD) bracket, but DO NOT tighten at this stage.
  8. Tighten bolts in sequence shown and to specification by numbers indicated. (Scheme 20) See «TORQUE SPECIFICATIONS»(ref-159181-S03504048662003111700000).
