    Tappet Clearance Cylinder Head LH Ensure "L" mark on camshaft (a) is aligned to cylinder head. Ensure the flat edge of the special tool (a) is correctly located in the slot on the camshaft on RH side AND the tool is resting correctly on the cylinder head. Gently rotate crankshaft to ensure proper seating of the tool in the camshaft slot and cylinder head. Loosen tappet adjuster screw locknut (a) with tappet adjusting tool and ensure locknut is sufficiently loose. Insert a screwdriver into the tappet adjusting tool (b) and ensure it is seated correctly on the adjuster screw (a). Locate feeler strip (a) between adjuster screw and valve stem as per thickness mentioned below. Gently pull out feeler strip (a) and check if it comes out freely OR with resistance. In case feeler strip comes out freely the adjuster screw has to be tightened. In case feeler strip movement is hard, the adjuster screw must be loosened. Tighten/loosen adjuster screw using screw driver, while simultaneously checking correct and smooth movement of feeler strip. Ensure tappet adjusting tool (a) does not rotate while adjusting the screw. After setting correct gap, remove feeler strip, hold screw driver firmly such that the setting DOES NOT gets disturbed and gently lock the lock nut against rocker arm using special tool (a). Repeat above steps to adjust the other tappet in cylinder head LH.
