AUTO TENSIONER INSTALLATION
1. Apply 98 - 196 N force to the push rod of 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
A: Length when it is free (not pressed)
B: Length when it is pressed
A - B: Movement
2. If it is out of the standard value, change the auto tensioner.
3. Use a press or vice 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 push rod
may become damaged, so be sure to carry out this
operation slowly.
4. 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.
5. Install the auto tensioner to the engine.
