Removal

Removal

1. Remove the crankshaft pulley, engine coolant pump pulley and drive belt.

2. Remove the timing belt cover.






3. Turn the crankshaft clockwise and align the timing marks so as to bring the No.1 cylinder to compression top-dead-center position. At this time the timing marks of the camshaft sprocket and the upper surface of the cylinder head should coincide, and the dowel pin of the camshaft sprocket should be at the upper side. Remove the auto tensioner.

Caution: Rotate the crankshaft clockwise.

4. Remove the timing belt.






Note: If the timing belt is reused, make an arrow mark Indicating the turning direction (or the front of the engine) to make sure that the belt is reinstalled in the same direction as before.






5. Remove the camshaft sprockets.

Note: Be careful not to damage the cylinder head with the wrench.






6. When the oil pump sprocket nut is removed, first remove the plug at left side of the cylinder block and insert a screwdriver to keep the left counter balance shaft in position. Screwdriver used for this purpose should have a shaft 8 mm (0.3 in.)in diameter which can be inserted more than 80 mm (2.36 in.)

7. Remove the oil pump sprocket retaining nut and remove the oil pump sprocket.

8. Loosen the right counter balance shaft sprocket mounting bolt until it can be loosened by hand.






9. Next, remove tensioner "B" and remove timing belt "B".

Caution: After timing belt "B" has been removed, do not attempt loosening bolt, while holding sprocket with pliers, etc.

10. Remove the crankshaft sprocket "B" from crankshaft


Inspection

Sprockets, Tensioner Pulley, and Idler Pulley

1. Check the camshaft sprocket, crankshaft sprocket, tensioner pulley, and idler pulley for abnormal wear, cracks, or damage. Replace as necessary.






2. Inspect the tensioner pulley and the idler pulley for easy and smooth pulley rotation and check for play or noise. Replace as necessary.

3. Replace if there is a grease leak.

Auto Tensioner






1. Check the auto tensioner for leaks and replace as necessary.

2. Check the rod end for wear or damage and replace as necessary.






3. Measure the rod protrusion. If it is out of specification, replace the auto tensioner.

Standard value 12 mm (0.47 in.)






4. Using a vise soft jaws push in the auto tensioner rod. If the rod can be easily retracted, replace the auto tensioner. You should feel a fair amount of resistance when pushing the rod in.

Caution: Clamp the auto tensioner in the vise so that It is level. Use soft jaws in the vise to avoid damaging the auto tensioner.






If the plug is at the bottom of the auto tensioner, Insert a plain washer to prevent direct contact if the plug with the vise.
Timing Belt






1. Check the belt for oil or dust deposits. Replace if necessary. Small deposits should be wiped away with a dry cloth or paper. Do not clean with solvent.










2. When the engine is overhauled or belt tension adjusted, check the belt in detail. If the following flaws are evident, replace the belt with a new one.
