Pump boosts transmission oil flow

Concentric product story

Concentric Pumps has developed an oil pump with double the original capacity for the new XtraShift transmission fitted in McCormick's high-rated CX Series tractors.
Concentric Pumps has developed an oil pump with double the original capacity for the new XtraShift transmission fitted in McCormick's high-rated CX Series tractors.
The oil pump is designed to cope with the increased performance and torque capacity for which the XtraShift transmission has been designed.
The pump is a robust, compact design with a sintered metal rotor and plastic filter.
The increased capacity has been achieved by maximising the rotor geometry and modifying the inlet to cope with the increased flow.
There are four tractors in the CX Series all powered by four-cylinder Perkins engines and ranging from 54 to 75kW output.
The XtraShift transmission offers power shuttle for clutchless shifts between forward and reverse and a greater choice of speeds - 24 x 24 as standard or 36 x 36 with creep.
The unit's three powershift speeds help to improve field performance and drivability, while the wet clutch design has been shown to reduce service and maintenance requirements.
