Valve Clearance Check: Check
- Remove the following items:
- Valve cover.
Refer to: VALVE COVER .
- RH fender splash shield.
Refer to: FENDER SPLASH SHIELD .
- Valve cover.
-
NOTE: Turn the engine clockwise only, and only use the crankshaft bolt.NOTE: Measure the clearance of each valve at base circle, with the lobe pointed away from the tappet.
Use a feeler gauge to measure the clearance of each valve and record its location.
Use the General Equipment: Feeler Gauge
-
NOTE: The number on the valve tappet only reflects the digits that follow the decimal. For example, a tappet with the number 0.650 has the thickness of 3.650 mm.NOTE: Select tappets using this formula: tappet thickness = measured clearance + the existing tappet thickness - nominal clearance.NOTE: The nominal clearance is:
- intake: 0.25 mm (0.0095 in).
- exhaust: 0.36 mm (0.0142 in).
NOTE: The acceptable clearances after being fully installed are:- intake: 0.19-0.31 mm (0.007-0.012 in).
- exhaust: 0.30-0.42 mm (0.012-0.017 in).
Select the closest tappet size to the ideal tappet thickness available and mark the installation location.
- If any tappets do not measure within specifications, install new tappets in these locations.
