Valve Timing, Checking: Procedure
-- Follow repair instructions. Refer to GENERAL INFORMATION .
-- Remove the cylinder head cover. Refer to CYLINDER HEAD COVER .
-- Lock the crankshaft in place for checking the valve timing. Refer to CRANKSHAFT, LOCKING TO CHECK/ADJUST VALVE TIMING .
Setting Valve Timing
Valve timing is correct when bolts of Camshaft Clamp T40070 can be screwed in easily to the end into camshafts as depicted. Support surfaces of Camshaft Clamp T40070 must lie flat on flats of camshaft when doing this.
-- If the bolts are difficult to install, position an 18 mm or 19 mm open-end wrench -A- at the opening on the exhaust camshaft and rotate the camshaft slightly in the -direction of the arrow- to remove any play in the chain drive.
If bolts of Camshaft Clamp T40070 can now be screwed in easily with chain drive tensioned in this manner, valve timing is also correct. Possibly the crankshaft was not secured correctly.
Valve Timing Is Not Set
Valve timing is not correct when bolts of Camshaft Clamp T40070 cannot be screwed in easily to the end into camshafts despite the tensioned chain drive.
- In this case it is necessary to adjust the valve timing. Refer to VALVE TIMING, ADJUSTING .
