If the oil fill line decal (858-003C) requires
replacement, adjust the center border line to the
height.
Inspect Hoses and Fittings
The PTO pump system is closed, any visible fluid
may be an indication of a leak.
1. Check that all hydraulic fittings are tight and dry.
Inspect all hoses for damage, wear, and fatigue.
Replace as needed.
Oil and Filter Change
For an oil change, a dry or fully dry system may
require as much as 6.5 gallons (25 liters) of oil to fill
the oil cooler, pump, motor, hoses, filter, and valve,
and leave 5.5 gallons (21 liters) in the oil reservoir. It
is recommended to use 10W-30 good quality, mineral
base hydraulic fluid, viscosity 70 to 250 SS at 210°F
(100°C). An oil change should be completed after 25
hours of initial use and all subsequence oil changes
should be completed whenever the oil filter is
changed.
After the first oil change is completed after 25 hours
of initial use, the oil filter should be changed every
150 hours or every 2 years. It is not necessary to
replace the oil filter during the first oil change.
Contact your Great Plains dealer to order
replacement oil filters.
1. Wait for the oil to cool.
2. Place a container under the drain plug (1) of the
reservoir, with at least a capacity of:
7 gallons (26 liters).
3. Carefully remove the drain plug.
4. Allow several minutes for oil in the filter (2) to
drain into and out of the oil reservoir. Change
filter as required. Seat filter per instructions on
filter.
5. Thread the plug back into the bottom of the
reservoir tank. Seating torque is 27 to 43
foot-pounds (37 to 58 N-m).
6. Add oil until the oil level in the tank, as observed
on the sight gauge (3), reaches the fill line on the
decal. It may take as much as 6.5 gallons (25
liters).
Flow Control Valve Adjustment
The flow control valve adjusts the percent of the PTO
pump output that is supplied to the PL5500 planter
hydraulic motors. The total pump flow, in gpm or
liters/min, is also directly proportional to PTO shaft
rpm.
An adjustment typically requires two persons. Pump
oil flow is ideally adjusted with all motors active under
simulated field workload, relying on Magnehelic®
pressure gauge readout, and in some cases, the
seed monitoring system rpm readout.
Setting Meter Pressurization
Entanglement and Crushing Hazard
Use extreme caution in the hitch area when the
PTO is operating.
Meter pressurization is set as for a standard PL5500
planter, using the PTO kit valve rather than a lever for
