Each cylinder must be checked by taking it to the T.D.C. (top dead centre) at the end of compression and adjusting the clearance of both valves on the cylinder in question.
Figure 49
Position the crankshaft at TDC of cylinder 1. Rotate crankshaft as required (see table) and check that intake and exhaust valves are both closed and not in a balanced position. For cylinder 4 it is possible to check the correct position of the crankshaft with tool 99360612. Adjust the clearance between the rockers and valves using a pair of pliers (2), a wrench (3) and a feeler gauge (1). Clearance shall be as follows: - intake valves 0.5 ± 0.1 mm - exhaust valves 0.50 ± 0.1 mm. FIRING SEQUENCE 1 - 3 - 4 - 2
