gauge pressure of 28 - 31 bar (400 - 450 psi) is achieved
(see Figure 2-14).
3. Stop engine. Remove diagnostic couplers and
reconnect plumbing.
Procedure G - For Checking/Setting the
Piston Pump (ISX Engine)
1. Install pressure check diagnostic quick disconnect with
gauge onto test nipple at GP2 port of the swing and
accessory manifold (see Figure 2-14).
2. Start engine and idle. Adjust the piston pump (P)
differential pressure adjusting screw “in” to increase or
“out” to decrease so that a gauge reading of 22 - 32 bar
(325 - 425 psi) is achieved (see Figure 2-21).
3. Stop engine. Remove diagnostic couplers.
Procedure H - For Checking the Center Front
Stabilizer Pressure
1. Install pressure check diagnostic quick disconnect with
gauge onto test nipple at GP at the inlet of the center
front stabilizer relief valve (see Figure 2-22).
2. Extend the center front stabilizer to the ground and hold
switch. Verify that a gauge reading of 10-20 bar (150 -
300 psi) is achieved (see Figure 2-22). This valve is not
adjustable.
3. Stop engine. Remove diagnostic couplers.
Procedure I - Procedures for Checking/
Setting the Piston Pumps (GSM Engine)
1. Install pressure check diagnostic quick disconnect
(Parker PD240) with gauge onto test nipple @ GP2 port
of the swing and accessory manifold (see Figure 2-14).
2. Screw out pump #2 adjusting screw two turns to
decrease its setting (see Figure 2-21). Start engine and
@ idle RPM adjust the piston pump #1 differential
setting screw “in” to increase or “out” to decrease so that
a gauge reading of 325-375 PSI (22-26 bar) is achieved
(see Figure 2-21). With the engine still @ idle RPM
adjust the piston pump #2 differential setting screw “in”
to increase so that a gauge reading of 375-425 PSI (26-
29 bar) is achieved (see figure #8).
3. Stop engine. Remove diagnostic couplers.
