b. Temporarily tighten the bolt on the front side of camshaft (INT) (1).
7. Put a thick shop cloth (B) to the lower surface, and then set the tools to the bolt camshaft (INT) (1).
8. Hold the camshaft hexagonal part (A), to secure the camshaft and tighten the bolt.
9. Return the camshaft (INT) to the cylinder head carefully.
10. Install the camshaft (EXH) to the camshaft sprocket (EXH) (2) while aligning the matching make (marked when timing chain is
removed) (A) and the matching mark (stamp) (B) of camshaft
sprocket (EXH).

11. Hold the camshaft hexagonal part (A), to secure the camshaft and tighten the bolt.
CAUTION:
• Make sure that the matching mark (marked when timing chain is removed) and each camshaft sprocket matching
mark are in the correct location.
12. Install camshaft brackets (No. 2 to 5) aligning the identification marks on upper surface as shown.
• Install so that identification mark can be correctly read when viewed from the INT side.
13. Tighten bolts of camshaft brackets in the following steps, in numerical order as shown.
a. Tighten No. 9 to 11 in numerical order.
b. Tighten No. 1 to 8 in numerical order.

14. Install timing chain with the following procedure.
• Install by aligning matching marks on each sprocket and tim-ing chain.
• If these matching marks are not aligned, rotate the camshaft
slightly to correct the position.
CAUTION:
• Check matching mark positi on of each sprocket and tim-
ing chain again after instal ling the timing chain, keep
matching marks aligned by holding them with a hand.
• To avoid skipped teeth, never rotate crankshaft and cam-
shaft until front cover is installed.
15. Install timing chain tension guide (2) and timing chain slack guide (1).
16. Install chain tensioner (1). • Fix the plunger at the most compressed position using a stop-per pin (A), and then install it.
• Securely pull out the stopper pin after installing the chain ten-
sioner.
17. Check matching mark position of timing chain and each sprocket again. A : Dark blue link

c. Tighten bolts in the numerical order shown.
d. After all bolts are tightened, retighten them to specified torque in numerical order as shown.
CAUTION:
Be sure to wipe off any excessive liquid gasket leaking to
surface.
22. Insert crankshaft pulley by aligning with crankshaft key. • When inserting crankshaft pulley with a plastic hamme r, tap on its center portion (not circumference).
CAUTION:
Never damage front oil seal lip section.
23. Tighten crankshaft pulley bolt with the following procedure: • Secure crankshaft pulley with a suitable tool, and tighten crankshaft pulley bolt.
a. Apply new engine oil to thread and seat surfaces of crankshaft pulley bolt.
b. Tighten crankshaft pulley bolt.
c. Put a paint mark (B) on crankshaft pulley, mating with any one of six easy to recognize angle marks (A) on crankshaft bolt flange
(1).
d. Turn another 60 degrees clockwise (angle tightening). • Check the tightening angle with movement of one angle mark.
24. Make sure that crankshaft turns smoothly by rotating by hand clockwise.
25. Install the camshaft position sensor (PHASE) to the rear end of cylinder head.
• Tighten bolts with it seated completely.
26. Check and adjust valve clearance. Refer to EM-20, " Inspection and Adjustment " .

• Make sure that there is no foreign material on the oil filter (1) and
check it for clogging.
• Check the oil filter (1) for damage.
• If there is some damage, replace t he oil filter (1), the plug, and the
washer as a set.
CAUTION:
Do not reuse the washer.
Camshaft Runout 1. Put V-block on a precise flat table, and support No. 2 and 5 jour- nals of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set a dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on the dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height 1. Measure the camshaft cam height with a micrometer (A).
2. If wear exceeds the limit, replace camshaft.

2. Install a dial indicator (A) in thrust direction on front end of cam- shaft. Measure the camshaft end play on the dial indicator when
camshaft is moved forward/backward (in direction to axis).
• Measure the following parts if out of the standard.
- Dimension “A” for cylinder head No. 1 journal bearing
- Dimension “B” for camshaft thrust
• Follow the standards above, and then replace camshaft and/or cylinder head.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journals of camshaft. CAUTION:
Never support No. 1 journal (on the side of cam shaft sprocket) because it has a different diameter

Measure the outer diameter of va lve lifter with a micrometer (A).
VALVE LIFTER HOLE DIAMETER
Measure the diameter of valve lifter hole of cylinder head with an
inside micrometer (A).
VALVE LIFTER CLEARANCE
• (Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter outer diameter)
• If out of the standard, referring to the each standard of valve lifter outer diameter and valve lifter hole diame-
ter, replace either or both valve lifter and cylinder head.
