Valve Clearance Check
Valve Clearance Check1. Remove the valve cover.
2. Remove the 5 bolts, the pin-type retainer (not shown) and the RH splash shield.
^ To install, tighten to 9 Nm (80 lb-in).
3. NOTE: Turn the engine clockwise only, and only use the crankshaft bolt.
NOTE: Before removing the camshafts, measure the clearance of each valve at base circle, with the lobe pointed away from the tappet. Failure to measure all clearances prior to removing the camshafts will necessitate repeated removal and installation and wasted labor time.
Use a feeler gauge to measure the clearance of each valve and record its location.
4. 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: A midrange clearance is the most desirable:
^ Intake: 0.22-0.28 mm (0.008-0.011 in)
^ Exhaust: 0.27-0.33 mm (0.010-0.013 in)
Select tappets using this formula: tappet thickness = measured clearance + the base tappet thickness - most desirable thickness. Select the tappets and mark the installation location.
5. If any tappets do not measure within specifications, install new tappets in these locations.
