MAINTENANCE

Oil Cooler

The HCU uses an oil cooler with an internally plumbed design to minimize the failure of hoses/fittings, cost and
space. The oil cooler is rugged aluminum, bar-plate construction, and has a non-fouling fin type that works well
in all environments. Moreover oil coolers have AKG's patented flex profiles to reduce thermal fatigue and
increase the service life of the cooler. The cooler volume is approximately 0.45 gallons.

Fan Hydraulic Motor

The HCU has a bi-rotational motor with anti-cavitation check valve and does not require a case drain port. The
hydraulic fan drive motor receives the high pressure flow from the manifold and the outlet is connected to the
hydraulic reservoir.
Displacement: 0.1102 cu. in.
Nominal Pressure: 3000 psi
Nominal Speed: 4000 rpm
Port: SAE-8, 3/4-16 UNFTHD
The max torque required for the SAE-8 port is around 54 ft-lbs. per SAE guidelines

Full System Relief manifold

The full system relief manifold is designed to simplify connections to the tank, pump and motor to reduce
complexity in the system during installation. The manifold is installed at the bottom of the HCU for easy
plumbing and serviceability.
System pressure on this manifold is set to 2500 psi and the flow control pressure compensated valve bleeds
the flow to the hydraulic fan drive motor. The flow control pressure compensated valve is set to 2 gpm for the
hydraulic motor to run the fan.
