2.1.1 Disassembly of Mechanical Parts

The correct sequence is the following:

• The pump shaft tab

• 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.

Push the plunger guides forward with their con-rods to facilitate side extraction of the pump. there are two

reference points visible on the shaft, 1, as shown in fig. 3 and in fig. 3a. These must be turned toward the

operator to facilitate extraction.

Note: Extraction of the plunger guides depends on prior removal the ceramic plunger and the relative spray

hood.

• Disassemble the con-rod units:

1. Unscrew the con-rod cap fixing screws.

2. Extract the con-rod caps with their relative semi-bearings (fig. 4), taking special care of the

disassembly sequence during disassembly.

To avoid possible errors, caps and con-rod shanks have been numbered on one side (1, fig. 4a).
