INSPECTION

1. INSPECT NO. 1 CHAIN TENSIONER
(a) Check that the plunger moves smoothly when the ratchet pawl is raised with your finger.
(b) 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.

2. INSPECT CHAIN SUB-ASSEMBLY
(a) Using vernier calipers, 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 same measurements by pulling at 3 or more places selected at random.

3. INSPECT CHAIN TENSIONER SLIPPER
(a) Using vernier calipers, 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.

4. INSPECT NO. 1 CHAIN VIBRATION DAMPER
(a) Using vernier calipers, 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.

5. INSPECT CRANKSHAFT TIMING SPROCKET
(a) Wrap the chain around the timing sprocket.
(b) Using vernier calipers, measure the timing gear diameter with the chain.
Minimum gear diameter (with chain): 51.6 mm (2.031 in.)

NOTICE: Vernier calipers 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.

6. INSPECT OIL PUMP DRIVE GEAR
(a) Wrap the chain around the drive gear.
(b) Using vernier calipers, measure the drive gear diameter with the chain.
Minimum gear diameter (with chain): 48.2 mm (1.898 in.)

NOTICE: Vernier calipers 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 gear.

7. INSPECT OIL PUMP DRIVE SHAFT GEAR
(a) Wrap the chain around the drive shaft gear.
(b) Using vernier calipers, measure the drive shaft gear diameter with the chain.
Minimum gear diameter (with chain): 48.2 mm (1.898 in.)

NOTICE: Vernier calipers 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 gear.

REPLACEMENT

1. REMOVE TIMING CHAIN COVER OIL SEAL
(a) Using a screwdriver and hammer, tap out the oil seal.
2. INSTALL TIMING CHAIN COVER OIL SEAL
(a) Place the oil seal retainer on wooden blocks.

(b) Using SST and a hammer, tap in the oil seal until its surface is flush with the timing gear case edge.
SST 09223-22010

NOTICE:
^ Keep the lip free from foreign matter.
^ Do not tap the oil seal at an angle.

HINT: Apply a light coat of MP grease to the lip of a new oil seal.
