REPLACEMENT OF THE (LUBRICANT) RELIEF
VALVE
(G025 ONLY)
To protect the circulation of the lubricant
(or grease), the pump includes an
integrated pressure relief valve. This
opens at a pressure of 4060 psi
(280 bar)
.
To replace the pressure relief valve, you
first have to remove the plug (AS) using a
hex key wrench (t25). Then using a
ratchet (t67) and 9mm socket (t24),
remove the relief valve cartridge assembly
(bs25).
NOTE: When installing the assembly,
make sure that the ball (bs31),
plunger (c19) and spring (bs13)
are arranged correctly in the
relief valve housing (a68).
Further, when tightening the relief
assembly, make sure to fit it correctly in
the pump housing as it seals against a flat
surface.
After installing the relief valve cartridge,
install the plug and sealing ring.
