The correct sequence is the following:

• pump shaft key

• rear cover

• connecting rod cap

• side covers, using 3 wholly threaded M6 x 50 screws, inserting

them in the holes as shown in fig. 2.

B) Push the plunger guides and connecting rods forward in order to facilitate the lateral extraction of the

crankshaft. Two marks are visible on the crankshaft (3), as shown in fig. 3 and fig. 3a; they must be turned
