1. INSPECT CHAIN SUB-ASSEMBLY

A139523E02

Using a spring scale, pull the chain with a force of 147 N (15 kgf, 33 lbf) as shown the illustration.

Using a vernier caliper, measure the length of 15 pins.
Maximum chain elongation:
136.9 mm (5.389 in.)
If the elongation is greater than the maximum, replace the chain.
ПРИМЕЧАНИЕ:
Perform the measurement at 3 random places.

2. INSPECT NO. 2 CHAIN SUB-ASSEMBLY

A139523E03

Using a spring scale, pull the chain with a force of 147 N (15 kgf, 33 lbf) as shown the illustration.

Using a vernier caliper, measure the length of 15 pins.
Maximum chain elongation:
137.6 mm (5.417 in.)
If the elongation is greater than the maximum, replace the chain.
ПРИМЕЧАНИЕ:
Perform the measurement at 3 random places.

3. INSPECT CRANKSHAFT TIMING GEAR

A148252

Wrap the chain around the sprocket.

Using a vernier caliper, measure the sprocket diameter with the chain.
Minimum sprocket diameter (w/ chain):
61.4 mm (2.417 in.)
УКАЗАНИЕ:
1. The vernier caliper must contact the chain rollers for the measurement.
2. If the diameter is less than the minimum, replace the chain and sprocket.

4. INSPECT CRANKSHAFT TIMING SPROCKET LH

A148253

Wrap the chain around the sprocket.

Using a vernier caliper, measure the sprocket diameter with the chain.
Minimum sprocket diameter (w/ chain):
61.4 mm (2.417 in.)
УКАЗАНИЕ:
1. The vernier caliper must contact the chain rollers for the measurement.
2. If the diameter is less than the minimum, replace the chain and sprocket.

5. INSPECT NO. 1 CHAIN TENSIONER ASSEMBLY

A148251E01

Move the stopper plate upward to release the lock. Push the plunger and check that it moves smoothly.
If necessary, replace the chain tensioner.

6. INSPECT NO. 2 CHAIN TENSIONER ASSEMBLY

A148258E01

Check that the plunger moves smoothly.

Measure the worn depth of the chain tensioner.
Maximum depth:
0.9 mm (0.035 in.)
If the depth is greater than the maximum, replace the chain tensioner.

7. INSPECT NO. 3 CHAIN TENSIONER ASSEMBLY

A148259E03

Check that the plunger moves smoothly.

Measure the worn depth of the chain tensioner.
Maximum depth:
0.9 mm (0.035 in.)
If the depth is greater than the maximum, replace the chain tensioner.

8. INSPECT CHAIN TENSIONER SLIPPER

A148254E01

for Bank 1:
1. Measure the worn depth of the chain tensioner slipper.
  Maximum depth:
  1.0 mm (0.039 in.)
  If the depth is greater than the maximum, replace the chain tensioner slipper.

A148257E01

for Bank 2:
1. Measure the worn depth of the chain tensioner slipper.
  Maximum depth :
  1.0 mm (0.039 in.)
  If the depth is greater than the maximum, replace the chain tensioner slipper.

9. INSPECT NO. 1 CHAIN VIBRATION DAMPER

A148255E01

for Bank 1:
1. Measure the worn depth of the chain vibration damper.
  Maximum depth:
  1.0 mm (0.039 in.)
  If the depth is greater than the maximum, replace the chain vibration damper.

A148256E01

for Bank 2:
1. Measure the worn depth of the chain vibration damper.
  Maximum depth:
  1.0 mm (0.039 in.)
  If the depth is greater than the maximum, replace the chain vibration damper.
