- Check that the plunger moves smoothly when the ratchet pawl is raised with your finger.
- Release the ratchet pawl, then check that the plunger is locked in place by the ratchet pawl and does not move when pushed with your finger.
- Inspect chain sub-assembly
- Using a vernier caliper, measure the length of the 16 links with the chain fully stretched.
Maximum chain elongation: 122.6 Mm (4.827 In.)
If the chain elongation is greater than the maximum, replace the chain sub-assembly.
Hint:
Take the measurements at 3 or more places selected at random.
- Inspect no. 2 Chain sub-assembly
- Using a vernier caliper, measure the length of the 8 links with the chain fully stretched.
Maximum chain elongation: 52.4 Mm (2.063 In.)
If the chain elongation is greater than the maximum, replace the no. 2 Chain sub-assembly.
Hint:
Take the measurements at 3 or more places selected at random.
- Inspect chain tensioner slipper
- Using a vernier caliper, measure the tensioner slipper wear.
Maximum wear: 1.0 Mm (0.039 In.)
If the wear is greater than the maximum, replace the chain tensioner slipper.
- Inspect no. 1 Chain vibration damper
- Using a vernier caliper, measure the vibration damper wear.
Maximum wear: 1.0 Mm (0.039 In.)
If the wear is greater than the maximum, replace the no. 1 Chain vibration damper.
- Inspect crankshaft timing sprocket
- Wrap the chain around the timing sprocket.
- Using a vernier caliper, measure the timing gear diameter with the chain.
Minimum gear diameter (with chain): 51.6 Mm (2.031 In.)
Notice:
The vernier caliper must be in contact with the chain rollers when measuring.
If the gear diameter is less than the minimum, replace the chain sub-assembly and crankshaft timing sprocket.
- Inspect oil pump drive sprocket
- Wrap the chain around the drive sprocket.
- Using a vernier caliper, measure the drive gear diameter with the chain.
Minimum gear diameter (with chain): 48.2 Mm (1.898 In.)
Notice:
The vernier caliper must be in contact with the chain rollers when measuring.
If the gear diameter is less than the minimum, replace the no. 2 Chain sub-assembly and oil pump drive sprocket.
- Inspect oil pump drive shaft sprocket
- Wrap the chain around the drive shaft sprocket.
- Using a vernier caliper, measure the drive shaft gear diameter with the chain.
Minimum gear diameter (with chain): 48.2 Mm (1.898 In.)
Notice:
The vernier caliper must be in contact with the chain rollers when measuring.
If the gear diameter is less than the minimum, replace the no. 2 Chain sub-assembly and oil pump drive shaft sprocket.

Air mix damper control servo motor circuit (driver
side)
Description
The air mix damper servo sends pulse signals to indicate the damper position
to the air conditioning
amplifier. The air conditioning amplifier activates the motor (normal or
reverse) based on these signals to
move the air mix damper (driver seat) to the appropriate position. T ...
