NOTICE
Never run the hydraulic pump unless the hydraulic
oil tank is full (indicated in sight level gauge).
1. Place a large waste oil container under the
tank drain port. The hydraulic tank holds
approximately forty gallons of oil.
2. Drain the hydraulic tank by removing the drain
plug from the tank. Remove the fi ll cap to
allow faster draining of oil. Allow the tank to
drain completely. Replace the drain plug.
3. Replace the fi lter by following steps one
through three in Section 10.2.1.
4. Fill the tank to the fi ll line at the top of the
gauge with approximately forty gallons of AW
HVI Hydraulic ISO 32 oil. Replace the fi ll cap.
5. Start the engine and cycle all the cylinders
several times.
6. Recheck the oil level in the tank and add as
needed.
10.2.3 Hydraulic Pressure Relief Valves
NOTICE
The pressure relief valves have been factory preset
for the most effi cient operation of the seed tender.
Do not adjust these relief valves. If the unit is not
operating properly, call your authorized Meridian
dealer.
10.2.4 Hydraulic Pump Coupling
Changing the pump coupling does not require the
hydraulic tank to be drained. If the pump must
be disconnected, drain the hydraulic tank and be
prepared to catch any oil that remains in the two
hydraulic hoses.
1. Remove the two pump mounting bolts.
2. Pull the pump away from the adapter to
separate the coupling halves.
3. Loosen the setscrews in each coupling half
and remove the old couplings. Install new
couplings on the engine shaft and the pump
shaft. When completely assembled, the shaft
length in each coupling half should be the
same. Tighten the pump end setscrews to 78
to 87 lb-in. Do not tighten the engine shaft
coupling at this time.
4. Place the urethane spider in the pump coupling.
Align and install the pump and pump coupling.
5. Tighten the pump bolts to a “Grade 5” bolt
toque for that size of bolt.
6. Slide the engine coupling against the other
coupling half and tighten the setscrew.
Note: If the adapter plate was removed, tighten
the four retaining bolts to “Grade 5” bolt
torque for that size of bolt.
