Engine Valve Clearance
Adjusting The Valve Clearance
After the first 1000 hrs. the cylinder head bolts should be
re-tightened to a torque as recommended. The bolt in the
center should be tightened first and then work outwards.
Check the valve clearance as given in specifications.
Following this a further check should be made after every
1000 hrs.
1. Remove the valve housing.
2. Turn the engine until the No. 1 cylinder is at the top
dead center of the compression stroke.
3. Loosen the locknut and adjust the screw in each valve
lever so that the feeler gauge slips snugly between the
ends of the valve lever and the valve stem.
4. Tighten the locknut and re-check the clearance.
5. Crank the engine for 2/3 revolutions in case of
3 cylinder engine in order to bring the TDC position of
subsequent cylinder number as per the respective firing
orders. Now adjust the valve clearance as explained
earlier.
Repeat the process until clearance for each set of valves is
adjusted.
Replace the valve housing and ensure that the valve
housing gasket makes an oil tight seal with the cylinder
head. Use a new gasket, if necessary.
Be accurate - use a feeler gauge for checking
the valve clearance.
