Drive shafts – a wide variety of options are available to suit every need.

High strength swashplates on variable pumps and motors – resist deflection under high load.

High strength cast iron housings – provide greater noise damping and wall strength.

High flow check valves in pumps – keep the system primed with minimal pressure drop.

Charge pumps on pumps – gerotor type, several displacement options are avail- able to suit the needs of every application. All cast iron construction.

Cartridge shaft seal – lends itself to easy serviceability. Mechanical face seal design tolerates high speed and high case pres-

Advanced cylinder barrel design – permits high speed and pressure.

Fixed clearance slipper hold down – on Models 33 through 64 allows operation at high speed and reduces friction. Model 76 is a ball guide unit.

Pistons – have long engagement with cylinder bore resulting in low leakage.

Hydraulic servo control – provides low effort operation with low control pressure. Large servo pistons hold swashplate position and provide damping.

Large case drain ports – minimize case back pressure.
