(3) Loosen the rocker arm locknut (b) using the
SST (49 G012 004), and then turn the
adjusting screw (a) using the SST (49 G012
005) until it is separated from the rocker
bridge completely.
(4) Insert a feeler gauge between the rocker arm
and rocker bridge (e).
Standard valve clearance [Engine cold]
IN: 0.12—0.18 mm {0.005—0.007 in}
(0.15±0.03 mm {0.006±0.0011 in})
EX: 0.32—0.38 mm {0.013—0.014 in}
(0.35±0.03 mm {0.014±0.0011 in})
(5) Adjust the valve clearance by turning the
adjuster (a) using the SST (49 G012 005).
Then temporarily tighten locknut (b) using the
SST (49 G012 004).
(6) With the feeler gauge inserted between the
rocker arm and rocker bridge, verify that the feeler gauge remains firmly in place even when the adjusting
screw (c) is loosened.
•If the feeler gauge does not remain firmly in place, repeat procedures from Step 1.
(7) Turn the adjusting screw (c) using the SST (49 G012 005) until it reaches the valve stem and the feeler
gauge fits more firmly. Then tighten the locknut (d) using the SST (49 G012 004) to specified torque.

COMPRESSION INSPECTIONA6E231402000201
Warning
•When the engine and the oil are hot, they can badly burn. Be careful not to burn yourself during
removal/installation of each component.
1. Verify that the battery is fully charged.
•Recharge it if necessary. (See G–6 BATTERY INSPECTION.)
2. Warm up the engine to the normal operating system temperature.
3. Stop the engine and allow it to cool off for about 10 min.
Warning
•Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and
damage. Fuel can also irritate skin and eyes. To prevent fuel from spurting out of the glow plug
hole, do not ground the fuel injector terminal. (See F2–45 Fuel Line Safety Procedures.)
4. Disconnect the fuel injector connector.
Warning
•If the glow plug harness connector is connected, the glow plug harness and engine component
can come into contact and cause a short when the engine switch is ON. Disconnect the glow plug
harness connector before turning the engine switch on.
5. Remove the engine cover. (See B2–9 TIMING BELT REMOVAL/INSTALLATION.)
6. Remove all the glow plugs. (See F2–42 GLOW
PLUG REMOVAL/INSTALLATION.)
