Installation Service Points
]A[ Auto Tensioner Installation.
Apply 98 - 196 N (22 - 44 lbs.) force to the push rod to the auto tensioner by pressing it against a metal (cylinder, block, etc.), and measure the movement of the push rod.
Standard value: Within 1 mm (0.04 inch)
A: Length when it is free (not pressed)
B: Length when it is pressed
A - B: Movement
If it is out of the standard value, replace the auto tensioner.
Use a press or vise to gently compress the auto tensioner push rod until pin hole A of the push rod and pin hole B of the tensioner cylinder are aligned.
CAUTION: If the compression speed is too fast, the rod may become damaged, so be sure to carry out this operation slowly.
Once the holes are aligned, insert the set pin.
NOTE: When replacing the auto tensioner with a new part, the pin will be in the auto tensioner.
Install the auto tensioner to the engine.
]B[ Timing Belt Installation.
Align the timing marks on the camshaft sprocket, crankshaft sprocket and oil pump sprocket.
After aligning the timing mark on the oil pump sprocket, remove the cylinder block plug and insert a Phillips screwdriver with a diameter of 8 mm (0.32 inch) , and check to be sure that the screwdriver goes in 60 mm (2.36 inch) or more. If the screwdriver will only go in 20 - 25 mm (0.79 - 0.98 inch) before striking the counterbalance shaft, turn the sprocket once, realign the timing mark and check that the screwdriver goes in 60 mm (2.36 inch) or more. Do not take out the screwdriver until the timing belt is installed.
Install the timing belt so as not to be loosened among the sprockets, by the following procedure.
CAUTION: If the timing belt is to be reused, install it so that the mark indicates the clockwise direction.
Set the tension pulley so that the pin holes are at the bottom, press the tension pulley lightly against the timing belt.
Screw the tool into the engine left support bracket until its end makes contact with the tensioner arm. At that point, screw the tool in some more and then remove the set wire attached to the auto tensioner.
Remove the tool.
Tighten the center bolt to the specified torque.
Specified torque: 48 Nm (35 ft. lbs.)
]C[ Timing Belt Tension Adjustment.
After turning the crankshaft 1/4 of a revolution counterclockwise, turn it clockwise until the timing marks are aligned.
Loosen the tension pulley fixing bolt, and then use the special tool and a torque wrench to tighten the fixing bolt to the specified torque while applying tension to the timing belt.
3.5 Nm (2.6 ft. lbs.)
[Timing belt tension torque]
CAUTION: When tightening the fixing bolt, do not let the tension pulley turn with the bolt.
Turn the crankshaft two revolutions clockwise so that the timing marks are aligned. After leaving it for 15 minutes, measure the amount of protrusion of the auto tensioner.
Standard value (A): 3.8 - 4.5 mm (0.150 - 0.177 inch)
If the amount of protrusion is outside the standard value, repeat the operation in steps (1) to (3).
Check again that the timing marks of each sprocket are aligned.
