9.7. Reducing throttle to the 1,200-1,500 RPM range,
observe the flow while pushing the loader valve
lever forward to the detent. The flow should be
around 5.0 GPM (19.0 LPM).
9.8. While holding the loader valve lever forward
gains the detent (but not into Float), slowly close
the flow valve on the test kit. See Fig-
ure 9.8.
NOTE: Because of the relief feature built into the
loader valve, as pressure approaches the relief
point of 1,500 PSI (103 Bars) more fluid will be
diverted to the return manifold. As more fluid is
diverted, the flow meter will show progressively
lesser readings while the pressure remains con-
stant at 1,500 PSI (103 Bars). If the flow valve
on the test kit is closed completely, flow will stop
completely.
CAUTION: If pressure rises substantially above
1,500 PSI (103 Bars) discontinue the test imme-
diately. Correct the pressure relief issue before
continuing.
9.9. The test described above will check the ability of
the hydraulic system to apply downward pres-
sure to the boom. The test can be reversed, to
check lifting ability by reversing the connection
of the test kit and pulling the loader valve control
lever back instead of pushing forward.
9.10. The same procedures will work for testing the
controls for the roll operation of the bucket, but
the test kit will be connected to couplers 2 and 4
(second one in, red band and far inboard cou-
pler, yellow band).

9.11. If the pressure varies slightly in above or below
1,500 PSI (103 Bars), the relief valve can be
adjusted. It is located on the top, outboard cor-
ner of the loader valve.
9.12. In order to adjust the relief valve, it is necessary
to remove the right side fender cover.
See Figure 9.12.
9.13. Remove the handles from the hydraulic lift con-
trol lever and the high-low range gear selector
lever by pulling them off.
9.14. Remove the knob and boot from the loader valve
control handle. The knob has normal right-hand
threads.
9.15. Remove the fender cover using a T-40 driver
from inside the fender. See Figure 9.15.
