2.1.1 Crank Mechanism Disassembly
The correct sequence is the following
A)
Drain oil and then remove:
• pump shaft key
• connecting rod cap
• side covers using 3 wholly threaded M6 x 50 screws, inserting them in the opposite holes
as shown in fig. 2
B)
Push the plunger guides and connecting rods forward in order to facilitate the lateral
extraction of the pump shaft. Two marks are visible on the crankshaft, as shown in fig. 3; they
must be turned towards the operator in order to facilitate extraction. NOTE: to extract the
plunger guide it is necessary to remove the ceramic plunger and wiper first.
C)
Disassemble the crankshaft oil seals and the plunger guides using standard tools.
