3) Rear wheel cylinder fluid pressure measurement
Step on the brake pedal until the fluid pressure of the front wheel cylinder gets to 9.8Mpa (100kg/cm
2), and
check the rear wheel cylinder fluid pressure. (Read the
value of the front wheel cylinder fluid pressure 2
seconds after the measurement. W hen measuring the
LSPV fluid pressure, keep the brake pedal pressed
down without stepping it down twice or releasing it.)

2. Oil Pressure Adjustment
1) LSPV spring length adjustment
Loosen the adjust nut of the LSPV spring joint, and adjust the length of the LSPV spring.
W hen the oil pressure is insufficient, turn the adjust nut clockwise to extend the span “A”. W hen the oil pressure
is too high, turn the adjust nut counterclockwise to
reduce the span “A”.


2) After adjustment, tighten the lock nut securely.

VALVE CLEARANCE ADJUSTMENT
1. Bring the piston in either the No. 1 cylinder or the No. 4 cylinder to TDC on the compression stroke by turning
the crankshaft until the crankshaft damper pulley TDC
line is aligned with the timing pointer.

2. Check the rocker arm shaft bracket nuts for
looseness.
Tighten any loose rocker arm shaft bracket nuts
before adjusting the valve clearance.

8. Check for play in the No. 1 intake and exhaust valve
push rods.
If the No. 1 cylinder intake and exhaust valve push
rods have play, the No. 1 piston is at TDC on the
compression stroke.
If the No. 1 cylinder intake and exhaust valve push
rods are depressed, the No. 4 piston is at TDC on the
compression stroke.

014RY00016
Adjust the No.1 or the No. 4 cylinder valve clearances
while their respective cylinders are at TDC on the
compression stroke.
Valve Clearance (At Cold) mm (in)
0.4 (0.016)

9. Loosen each valve clearance adjusting screw as
shown in the illustration.
10. Insert a feeler gauge of the appropriate thickness between the rocker arm and the valve stem end.

014RY00017


11. Turn the valve clearance adjusting screw until a slight
drag can be felt on the feeler gauge.
12. Tighten the lock nut securely.
13. Rotate the crankshaft 360 °.
14. Realign the crankshaft damper pulley TDC notched line with the timing pointer.
15. Adjust the clearances for the remaining valves as shown in the illustration.

Oil Seal Installation
Use the special tool to install the front oil seal.
Front Oil Seal Installer: 5-8840-2361-0
1. With the oil seal attached to the sleeve, insert it into the front end section of the crankshaft.
2. With the oil seal end section attached securely to the crankshaft, tighten up the center bolt until the sleeve hits
the front end reference plane of the crankshaft securely.
3. Remove the sleeve.
4. With the seal pressed in, check the dimension of the oil seal section.
Standard Dimension = 1.0 ± 0.03mm

NOTE:
Install the oil seal after assembling the timing pulley
housing. The oil seal lip section is applied with oil.
Take notice of the press-in direction of the oil seal.

2. Support the radiator upper tank with the bracket (5) and secure the radiator.
3. Connect reserve tank hose (6).
4. Install lower fan guide (3).
5. Connect radiator inlet hose and outlet hose (1) to the engine.

2. For removal of the quick connector, hold the quick
connector in one hand, and pull out the connector with the
other hand while pressing the square relieve button of the
connector, as illustrated.
NOTE: Do not use tools of any kind. Only use bare hands
when disconnecting the connector. Use a lubricant (light oil)
and/or push and pull the connector until the pipe is
disconnected.





140R100028
Cover the connectors that was removed with a plastic bag,
to prevent dust or rain water from entering.






140R100036
Reuse of Quick–Connector
• Replace the port and connector if scratch, dent or crack is
found.
• Remove any dirt build up on the port when installing the
connector. Replace the connector, if there is any forms o
f
rust, dent, scratch.
• After cleaning the port, insert it straight into the connecto
r
until it clicks. After it clicks, try pulling at 49N (5kgf) it out to
make sure that it is not drawn and is securely locked.


Assembling Advice
By applying engine oil or light oil to the pipe, port makes pipe
assembly easier. The pipe assembly should take place
immediately after applying oil (to prevent dust from sticking to
the pipe surface – which may decrease sealing ability). Test/Inspection After Assembling
1. Reconnect the battery negative cable.
2. Start the engine and observe the engine idle speed. The presence of dirt in the fuel system may affect the fuel
injection system.
3. Check for fuel leakage from the connector.

4. Install the pin to the dial gauge.
Note:
The lengths of the pins do not include the threaded portions.
Pin (L=100 mm): 157892-5200 (Bosch AS)
Dial gauge: 157954-3800 (Bosch AS)

5. Secure the dial gauge to the nozzle holder using the nut so that the pin contacts the tip of the first spring
seat.

CAUTION:
• Secure the dial gauge so that a stroke of 2 mm can
be measured.
• Do not over-tighten the nut as the dial gauge shaft
may jam. (Confirm from the dial gauge that the
shaft moves smoothly.)

6. Set the nozzle holder to the nozzle tester and put needle to zero on the dial gauge.
7. Operate the nozzle tester to bleed any air from inside the retaining nut and to confirm that no fuel leaks.
