Operate the machine until the hydraulic oil reaches normal operating temperature.
Stop the machine on a hard, level surface. Move the transmission control lever to NEUTRAL. Lower the bowl. Stop the engine. Engage the parking brake.
Remove plug (1) .
Assemble the following components and connect to the open port: 9T-6865 Adapter Plug, 5P-2937 O-Ring Adapter and 6V-3966 Fitting As .
Connect 198-4240 Digital Pressure Indicator to the 6V-3966 Fitting As .
Start the engine. Run the engine at 1000 RPM.
Move the ejector control lever slowly toward EJECT position and observe the pressure gauge. The reading on the pressure gauge should be 12765 170 kPa (1850 25 psi).
As the load flows out of the bowl, the reading on the pressure gauge will decrease. When the reading decreases to 6035 515 kPa (875 75 psi), the valve stem in the ejector valve will shift and the ejector will move faster.Note: If the control lever is held in EJECT position, the reading will increase to the relief valve pressure.
If the high pressure setting requires adjustment, continue to Step 10. If the high pressure setting is correct, continue to Step 16.
If it is necessary to change the high pressure setting of the ejector valve, stop the engine.
Remove four bolts (9). Remove cover (5) .Note: Shims (6), springs (7) and (8), a retainer and a valve stem can come out of the ejector valve when cover (6) is removed.
Remove shims (6) in order to decrease the high pressure setting of the ejector valve. Add shims (6) in order to increase the high pressure setting of the ejector valve. Refer to Table 2 for the pressure change of the shims.
Install shims (6), springs (7) and (8), the retainer and the valve stem.
Install cover (5) and four bolts (9) .
Repeat Steps 6 through 9.
Stop the engine. Remove all test equipment.
Install plug (1) .
