Spectrum: 1.5 non turbo, broke timing belt..valves..crank..torque

Resolved Question:

I have an 89 geo spectrum 1.5 non turbo, broke timing belt--first what are the odds I didn't bend any valves, secondly having a difficult time getting the bottom crank pully off- even drilled a half inch hole through the frame, attached a breaker bar to it and it's not budging. Am I doing something wrong or do I just apply more torque to it? Mike

crakshaft Damper/Pulley



REMOVAL & INSTALLATION



Spectrum

Although it may be possible to access the crankshaft damper/pulley while the engine is still in the vehicle, it may be exceedingly difficult. The manufacturer recommends that the engine be removed before attempting to replace components such as the timing belt or the crankshaft damper/gear. To remove these components, refer to the appropriate procedures later in this section.

  1. Disconnect the negative battery cable.
  2. Remove the power steering belt from the crankshaft pulley.
  3. Remove the alternator belt.
  4. For the DOHC engine, remove the timing belt. Refer to the procedure later in this section.
  5. Raise and support the vehicle safely, then remove the right under cover.
  6. Remove the crankshaft pulley center bolt. For the DOHC engine, use J-8614-01, or an equivalent pulley holding fixture to prevent the crankshaft from turning.
  7. For the SOHC engine, remove the 5 side bolts, then remove the pulley from the engine.
  8. For the DOHC engine, use J-1859-03, or an equivalent puller to remove the pulley from the crankshaft.

To install:
  1. Align the crankshaft key with the pulley groove, then position the pulley onto the end of the crankshaft.
  2. Install the pulley center bolt and tighten to 87 ft. lbs. (118 Nm). For the DOHC engine, use the pulley holding fixture to prevent the crankshaft from turning. For SOHC engines, install the pulley side bolts and tighten to 17 ft. lbs. (23 Nm).
  3. Install the right under cover, then remove the supports and carefully lower the vehicle.
  4. For the DOHC engine, install the timing belt.
  5. Install the alternator belt.
  6. Install the power steering belt.
  7. Connect the negative battery cable.


  1. Disconnect the negative battery cable.
  2. Install an adjustable engine support fixture and adapter kit in order to support the engine weight once the engine mount is removed for access. If an engine hoist is being used as an engine support, raise and support the vehicle sufficiently for both underhood and undervehicle access.
  3. Remove the serpentine drive belt from the engine.
  4. Remove the bolt and nut from the right engine mount bracket, then remove the through-bolt from the mount. Remove the engine mount from the vehicle.
  5. Lower the engine using the support fixture, until the crankshaft pulley may be accessed from underneath the vehicle.
  6. If not done already, raise and support the vehicle safely.
  7. Remove the right splash shield.
  8. Remove the crankshaft pulley center bolt, then remove the pulley from the vehicle.

To install:
  1. Align the crankshaft key with the pulley groove, then position the pulley onto the end of the crankshaft.
  2. Install the pulley center bolt and tighten to 108 ft. lbs. (147 Nm).
  3. Install the right splash shield.
  4. If an engine hoist is not being used as the engine support, remove the supports and lower the vehicle.
  5. Use the engine support to align the engine with its original position.
  6. Install the right engine mount and loosely install the through-bolt. Install and tighten the bracket nut/bolt to 30 ft. lbs. (40 Nm), then tighten the through-bolt to 50 ft. lbs. (68 Nm).
  7. Install the serpentine drive belt.
  8. Remove the engine support fixture. If a hoist was use to support the engine, remove the jackstands and carefully lower the vehicle.
  9. Connect the negative battery cable.

Timing Belt

Print

REMOVAL & INSTALLATION



Although timing belts may last for thousands of miles past the recommended replacement interval, they should be replaced every 60,000 miles to prevent trouble or damage should they snap. Timing belts do not usually give an indication that they are worn or aging without removing the cover(s) and inspecting the belt. A worn or damaged belt could give out at any time. In some cases, should a timing belt snap while the engine is running, damage could be done to the valve trains or pistons requiring a partial or full engine disassembly. Also, should the belt go when the vehicle is far from home, a costly tow or even more costly repair job and considerable inconvenience may be suffered.

Timing belts must always be handled carefully and kept completely free of dirt, grease, fluids and lubricants. This includes any accidental contact from spillage, fingerprints, rags, etc.. These same precautions apply to the pulleys and contact surfaces on which the belt rides.The belt must never be crimped, twisted or bent. Never use tools to pry or wedge the belt into place. Such actions will damage the structure of the belt and possibly cause breakage.

Spectrum

See Figures 1, 2 and 3

The engine must be removed from the vehicle for this procedure to be performed.

  1. Remove the engine and mount it to an engine stand.
  2. Remove the accessory drive belts.
  3. Remove the engine mounting bracket from the timing cover.
  4. Rotate the crankshaft until the notch on the crankshaft pulley aligns with the 0 degree mark on the timing cover and the No. 4 cylinder is on TDC of the compression stroke.
  5. Remove the starter and install the flywheel holding tool No. J-35271 or equivalent.
  6. Remove the crankshaft bolt, boss and pulley.
  7. Remove the timing cover bolts and the timing cover.
  8. Loosen the tension pulley bolt.
  9. Insert an Allen wrench into the tension pulley hexagonal hole and loosen the timing belt by turning the tension pulley clockwise.
  10. Remove the timing belt.
  11. Remove the head cover.

Inspect the timing belt for signs of cracking, abnormal wear and hardening. Never expose the belt to oil, sunlight or heat. Avoid excessive bending, twisting or stretching.

To install:
  1. Position the Woodruff key in the crankshaft followed by the crankshaft timing gear. Align the groove on the timing gear with the mark on the oil pump.
  2. Align the camshaft timing gear mark with the upper surface of the cylinder head and the dowel pin in its uppermost position.
  3. Place the timing belt arrow in the direction of the engine rotation and install the timing belt, first to the crankshaft pulley, next to the camshaft pulley, then to the water pump pulley and finally to the tension pulley. Tighten the tension pulley bolt.

Once installed, there must be not slack in the timing belt. The belt teeth must be in perfect alignment with the gears.

  1. Turn the crankshaft 2 complete revolutions and realign the crankshaft timing gear groove with the mark on the oil pump.
  2. Loosen the tension pulley bolt and apply tension to the belt using an Allen wrench in the hexagonal pulley hole. Torque the pulley bolt to 37 ft. lbs. (50 Nm) while holding the pulley stationary.
  3. Check the timing belt tension using a belt tension gauge, it should be 40-48 lbs. (18-22 Kg).
  4. Adjust the valve clearances.
  5. To complete the installation, reverse the removal procedures. Torque the crankshaft pulley-to-crankshaft bolt to 108 ft. lbs. (147 Nm).
