INSPECTION
1. INSPECT TIMING CHAIN AND TIMING SPROCKETS





a. Using a vernier calipers, measure the length of 16 links with the chain dully stretched.
Maximum chain elongation: 122.6 mm (4.827 inch)
If the elongation is greater than maximum, replace the chain.

HINT: Mate the same measurements pulling at 3 or more places selected at random.





b. Wrap the chain around the timing sprocket.
c. Using a vernier calipers, measure the timing sprocket diameter with the chain.

NOTICE: Vernier calipers must contact the chain rollers for measuring

Minimum sprocket diameter (w/ Chain):
Camshaft 97.3 mm (3.831 inch)
Crankshaft 51.6 mm (2.031 inch)
If the diameter is less than minimum, replace the chain and sprockets.





2. INSPECT CHAIN TENSIONER SLIPPER AND VIBRATION DAMPER
Measure the chain tensioner slipper and vibration damper wears.
Maximum wear: 1.0 mm (0.039 inch)
If the wear is greater than maximum, replace the slipper and/or dart per.





3. INSPECT CHAIN TENSIONER
a. Check that the plunger moves smoothly when the ratchet pawl is raised with your finger.
b. Release the ratchet pawl and check that the plunger is locked in place by the ratchet pawl and does not move when pushed with your finger.
4. INSPECT OIL DIET

REPLACEMENT

HINT: The re are 2 methods (A and B) to replace the oil seal which are as follows:

REPLACE CRANKSHAFT FRONT OIL SEAL
a. If timing chain cover is removed from cylinder block.





1. Using a screwdriver and a hammer, tap out the oil seal.





2. Using SST and a hammer, tap in a new oil seal until its surface is flush with the timing chain cover edge.

3. Apply MP grease to the oil seal lip.
b. If timing chain cover is installed to the cylinder block.





1. Using a knife, cut off the oil seal lip.
2. Using a screwdriver, pry out the oil seal.

NOTICE: Be careful not to damage the crankshaft. Tape the screw driver tip.





3. Using SST and a hammer, tap in the oil seal until its surface is flush with the timing chain cover edge.
