Timing Belt
TIMING BELT1. Disassemble in the order shown in the figure, referring to Disassembly Note.
2. Assemble in the reverse order of disassembly, referring to Assembly Note.
Timing Belt:
Disassembly Note
Crankshaft pulley and plate
1. Hold the flywheel (MTX) or drive plate (ATX) by using the SST.
2. Remove the crankshaft pulley and plate.
Pulley boss
1. Turn the crankshaft clockwise and align the timing marks of the pulleys.
Note
^ Face the locating pin on the pulley boss and "Z" mark on the camshaft pulley straight up, and align the timing marks with the cylinder head upper surface.
2. Hold the flywheel (MTX) or drive plate (ATX) by using the SST.
3. Remove the pulley boss.
Timing belt
Caution
^ The following will damage the belt and shorten its life; Forcefully twisting it, turning it inside out, or allowing oil or grease on it.
1. Mark the timing belt rotation on the belt for proper reinstallation.
2. Loosen the tensioner lock bolt.
3. Push the tensioner in the direction of the arrow and hand tighten the lock bolt.
4. Remove the timing belt.
Assembly Note
Timing belt pulley and key
Insert the key into the timing belt pulley, facing the tapered side downward. Push the key until it stops.
Tensioner and tensioner spring
1. Install the tensioner spring as shown.
2. Push the tensioner in the direction of the arrow and hand tighten the lock bolt.
Timing belt
1. Verify that all timing marks are correctly aligned.
Note
^ Face "Z" mark on the camshaft pulley straight up and align the timing marks with the cylinder head upper surface.
2. Install the timing belt on the pulleys in the order shown below.
1) Timing belt pulley
2) No.2 idler pulley
3) No.1 idler pulley
4) Camshaft pulley
5) Tensioner
Pulley boss
1. Install the pulley boss and pulley lock bolt. Turn the crankshaft clockwise 1 and 5/6 times, and verify that the timing mark and the tensioner set mark (A) are aligned.
2. Loosen the tensioner lock bolt to apply tension to the timing belt. Do not apply tension other than that of the tensioner spring.
3. Tighten the tensioner lock bolt.
Tightening torque:
38-51 N-m (3.8-5.3 kgf-m, 28-38 ft-lbf)
4. Turn the crankshaft clockwise 2 and 1/6 times, and verify that all timing marks are correctly aligned.
Note
^ Timing is correct when the locating pin on the pulley boss and "Z" mark on the camshaft pulley are facing straight up, and the timing marks are aligned with the cylinder head upper surface.
5. Check the belt deflection at the point indicated by applying moderate pressure 98 N (10 kgf, 22 lbf).
Deflection: 7-9 mm (0.28-0.35 in)
6. If the timing belt deflection is not correct, remove the timing belt and repeat from timing belt assembly note step 1.
7. Hold the drive plate (ATX) or flywheel (MTX) by using the SST.
8. Tighten the pulley lock bolt.
Tightening torque:
157-166 N-m (16.0-17.0 kgf-m, 116-122 ft-lbf)
Crankshaft pulley and plate
1. Hold the drive plate (ATX) or flywheel (MTX) by using the SST.
2. Install the crankshaft pulley and plate.
Tightening torque:
12.3-17.1 N-m (1.25-1.75 kgf-m, 9.05-12.6 ft-lbf)
Cylinder head cover
1. Before installing the cylinder head cover, measure the valve clearances.
Caution
^ Silicone sealant hardens and causes oil leakage when it is left for an extended period.
2. Verify that the grooves on the cylinder head cover are free of oil, water and other foreign material.
3. Install the new cylinder head cover gasket into the cylinder head cover.
4. Apply silicone sealant to the shaded areas shown.
Thickness: [diameter] 3-4 mm (0.12-0.15 in)
5. Install the cylinder head cover.
6. Tighten the cylinder head cover bolts in five or six steps in the order shown.
Tightening torque:
6.9-10.7 N-m (70-110 kgf-cm, 61-95.4 in-lbf)
7. Retighten the bolts in the order shown.
Tightening torque:
6.9-10.7 N-m (70-110 kgf-cm, 61-95.4 in-lbf)
