Product Overview
The 708-1T-00540 is a high-performance axial piston hydraulic fan pump purpose-built for Komatsu D51-22 series bulldozers. As a core component of the engine cooling system, it delivers stable hydraulic flow to drive the cooling fan, maintaining optimal engine operating temperature under heavy-duty earthmoving, grading and site preparation working conditions.
This aftermarket replacement pump is manufactured strictly to original OEM specifications, with fully interchangeable mounting flanges, port sizes and performance parameters. It requires no modification during installation, directly replacing the failed original fan pump to restore your dozer's cooling efficiency and prevent engine overheating failures.
Key Functions & Applications
Transmits hydraulic power to drive the engine cooling fan
Automatically adjusts fan speed with hydraulic pressure changes
Ensures stable engine temperature during long-hour heavy load operations
Widely applied to construction, landscaping, road building and land clearing D51 series dozer fleets
Quality Control
Every 708-1T-00540 fan pump undergoes rigorous factory testing including pressure resistance test, flow rate calibration, seal leak test and load simulation test before packaging. We adopt high-strength cast iron housing, wear-resistant copper alloy valve plate and precision-machined piston assembly to guarantee long service life even in harsh dusty and high-temperature environments.
