2.2 Fluid End Repair

2.2.1 Disassembly of the Head - Liners - Valves

The pump head does not require periodic maintenance. Service operations are limited to valve inspection or

replacement if needed. To extract the valve units proceed as follows:

A) Loosen the M8 x 100 screws that fix the liners to the head as shown in fig. 12.

B)

Unfasten the head screws M12 x 260, #5 and #6 as shown in fig. 13, replacing them with two

auxiliary screws (p/n 27508200) as shown in fig. 14; then remove the remailing screws.
