CHARGE PUMP SYSTEM PRESSURE TEST - Continued
NOTE
Pressure tap is labeled "CP."
2.
Connect pressure gauge to pressure tap (Figure 1, Item 3) to vibratory control valve (Figure 1, Item 6).
NOTE
The charge relief pressure setting should be 360 + 20 psi (2,482 + 138 kPa).
3.
Start and run engine at HIGH idle, 2,325 + 25 rpm. Record pressure gauge reading.
4.
If needed, adjust as follows:
a.
Loosen locknut (Figure 1, Item 4).
b.
Turn adjustment screw (Figure 1, Item 5) clockwise to increase pressure, counterclockwise to decrease
pressure.
c.
After adjustment, tighten locknut (Figure 1, Item 4).
d.
Lower rpm to LOW idle and recheck pressure. Pressure should be greater than 300 psi (2,068 kPa).
5.
Shut engine off.
6.
Remove pressure gauge from tap (Figure 1, Item 3).
