How to check the tappet clearances
These are checked between the top of the tappet and the rocker lever (A1). For D3.152 engines the correct
clearances are 0,30 mm (0.012 in) for inlet and exhaust valves with the engine cold. For 3.1524 and T3.1524
engines the correct clearances are 0,20 mm (0.008 in) for the inlet valves and 0,32 mm (0.0125 in) for the
exhaust valves with the engine hot or cold.
Warning! Number 1 cylinder is at the front of the engine.
1 Turn the crankshaft in the normal direction of rotation until the inlet valve of number 1 cylinder has just
opened and the exhaust valve of the same cylinder has not closed completely. Check the clearances of valves
numbers 4 and 6 and adjust them, if it is necessary.
2 Make a mark on the crankshaft pulley and timing case cover and turn the crankshaft one complete revolution
(360
o
) until the marks align again. Check and adjust clearances of numbers 1, 2, 3 and 5 valves.
