- Remove the rocker cover.
- Turn the crankshaft at the sprocket fastening screw until the
cams of the tappets to be checked are pointing upwards.
- Determine the clearance between cams and tappets.
- If the clearance exceeds 0.1 mm, replace the tappet. If the
clearance measured is less than 0.1 mm or nil, continue the
check as follows:
- Press the tappet down with a wooden or plastic wedge. If free
travel in excess of 0.1 mm is perceptible before the valve
opens, replace the tappet.
NOTE: After installing new tappets, wait for approx. 30
minutes before starting the engine. The hydraulic
compensating elements must settle (valves could
strike pistons).
