2.1.1 Crank mechanism disassembly
The correct sequence is the following:
Disassemble:
• The pump shaft key
• The rear cover
• The connecting rod cap
• The side covers using for extraction 3 fully threaded M6x50 screws, inserting them
in the threaded holes as indicated in fig. 2.
B) Push the plunger guides and connecting rods forward to facilitate lateral extraction of the pump shaft.
Two marks are visible on the crankshaft (3, fig. 3 and 3a); 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.
