SHANTUI 705-51-30190 Bulldozer Hydraulic Gear Work Pump Assembly

● SHANTUI 705-51-30190 Pump Technical Support

● Part number 705-51-30190 (also recorded as 7055130190) is the genuine heavy-duty hydraulic gear work pump assembly engineered for SHANTUI crawler bulldozers.

● Material number 705-51-30190 is driven via the engine rear power take-off (PTO) splined shaft, continuously pumping pressurized hydraulic fluid into the main control valve bank. Its precision-ground external gear set generates high volumetric flow to power dozer blade lift, lower, tilt, and rear ripper hydraulic cylinders during demanding earthmoving and heavy grading tasks.

● Inspect suction line flange seals, ensure hydraulic fluid cleanliness with timely filter replacements, and monitor pump casing operating temperatures to maintain optimal volumetric efficiency and bearing life.
