2.2.4 Assembling the Plungers - Supports - Seals Assembly
Proceed with the reassembly, following the reverse of the disassembly procedure shown in 2.2.3.
Replace the pressure gaskets, moistening the lips with silicone grease (without
covering the gaskets), and taking great care not to damage them while inserting them
into the liner.
At every disassembly, the pressure gaskets must always be replaced, together with
all the O-rings.
Insert the low pressure gasket into the gasket support (pos. 1, fig. 149), taking care to follow the direction of
assembly: the seal lip goes in front (towards the head).
Insert the head ring (pos. 1, fig. 150), the high pressure gasket (pos. 1, fig. 151) and the restop ring
(pos. 1, fig. 152).
Place the O-ring for the gasket support on its seat (pos. 1, fig. 153).
