NOTICE: When disconnecting the battery negative terminal, initialize the system(s) shown after the terminal
1. DISCONNECT BATTERY NEGATIVE TERMINAL
2. REMOVE FRONT WHEEL RH
3. REMOVE ENGINE UNDER COVER RH
4. REMOVE ENGINE UNDER COVER LH
5. REMOVE FRONT FENDER APRON SEAL RH
6. REMOVE ENGINE COVER SUB-ASSEMBLY NO.1
7. REMOVE FAN AND GENERATOR V-BELT
SST 09249-63010
8. SEPARATE VANE PUMP ASSEMBLY
SST 09249-63010
9. REMOVE ENGINE MOUNTING INSULATOR RH
10. REMOVE IGNITION COIL ASSEMBLY
11. REMOVE CYLINDER HEAD COVER SUB-ASSEMBLY
12. SET NO. 1 CYLINDER TO TDC/COMPRESSION
13. CHECK VALVE CLEARANCE
a. Check only the valves indicated.
1. Using a feeler gauge, measure the clearance between the valve lifter and camshaft.
Valve clearance (Cold):
0.19 to 0.29 mm (0.0075 to 0.0114 inch) for intake
0.30 to 0.40 mm (0.0118 to 0.0158 inch) for exhaust
2. Record any out of specification valve clearance measurements. They will be used later to determine the required replacement valve lifters.
b. Turn the crankshaft 1 revolution (360°) and set the No.4 the cylinder to the TDC/compression.
c. Check only the valves indicated.
1. Using a feeler gauge, measure the clearance between the valve lifter and camshaft.
Valve clearance (Cold):
0.19 to 0.29 mm (0.0075 to 0.0114 inch) for intake
0.30 to 0.40 mm (0.0118 to 0.0158 inch) for exhaust
2. Record any out of specification valve clearance measurements. They will be used later to determine the required replacement valve lifters.
14. ADJUST VALVE CLEARANCE
a. Remove the No. 2 camshaft.
b. Remove the camshaft.
c. Remove the valve lifters.
d. Using a micrometer, measure the thickness of the removed valve lifters.
e. Calculate the thickness of a new lifter so that the valve clearance comes within the specified values.
Valve clearance:
Intake A = B + (C - 0.24 mm (0.0095 inch))
Exhaust A = B + (C - 0.35 mm (0.0138 inch))
HINT:
- Select a new lifter with a thickness as close to the calculated values as possible.
- Lifters are available in 35 sizes in increments of 0.020 mm (0.0008 inch), from 5.060 mm (0.1992 inch) to 5.740 mm (0.2260 inch).
- Refer to New Lifter Thickness table on the next 2 pages.
