60277674 Hydraulic Gear Motor Assembly Sany SAT40C Articulated Dump Truck Spare Parts

60277674 Proportional Hydraulic Fan Gear Motor for Sany SAT40C

The 60277674 Hydraulic Gear Motor Assembly (frequently referred to as the Hydraulic Fan Motor) is an advanced fluid power component that drives the engine cooling fan on the Sany SAT40C articulated dump truck. Heavy-duty dump trucks working in abrasive mining zones require highly adaptive cooling capabilities. Instead of a standard, belt-driven fan that runs relative to engine speed, the Sany cooling package uses this independent hydraulic gear motor. Driven by pressurized hydraulic oil, the motor’s speed is regulated dynamically by the truck’s engine control unit (ECU) via an integrated proportional solenoid valve. This on-demand speed modulation ensures maximum cooling capacity while reducing fuel consumption and engine noise.

We supply the fully integrated 60277674 hydraulic motor group as well as its core serviceable sub-components, including replacement solenoid coils, valves, flat keys, and high-integrity shaft oil seals. Both genuine Sany OEM motors and highly reliable aftermarket options are in stock for rapid international shipping.

60277674 Assembly Component Parts List

Below is the detailed parts catalog list for the sub-components of the 60277674 Hydraulic Gear Motor as referenced in the Sany SAT40C technical manual. These components can be ordered individually for targeted motor servicing or overhauls:

Features & Benefits of Our Hydraulic Fan Motor Assembly

• ECU Proportional Speed Control: The integrated solenoid valve stem (150204010018A003) and coil (150204010018A002) modulate bypass hydraulic flow. This allows the truck’s engine ECU to adjust cooling fan speed smoothly based on real-time fluid temperatures.
• Dual-Lip Shaft Sealing: Equipped with a high-pressure Shaft Oil Seal (150204010018A001) and an external Dust Oil Seal (150204010018A005). This dual-barrier system retains high-pressure hydraulic oil internally while blocking abrasive mining dust from entering the bearing cavity.
• High-Torque Gear Drive: Built with robust internal spur gears machined to close tolerances, delivering consistent torque and rotating the heavy cooling fan blade efficiently under maximum thermal demand.

Ordering & Technical Maintenance Guidelines

1. Verify Electrical Connector Compatibility: The proportional solenoid coil (item 2) uses a specific electrical connector. Please provide your Sany SAT40C’s chassis serial prefix or engine identification plate so our technical team can verify the plug wiring and voltage configurations.
2. Always Change Seals on Motor Rebuilds: High-pressure oil seals (item 3) and dust seals (item 7) are wear items subject to friction and heat. Always replace these seals during any hydraulic motor service or fan overhaul to prevent hydraulic fluid leaks onto the cooling fins.
3. Purge Hydraulic Lines on Installation: Air pockets in hydraulic fan motor lines can cause localized cavitation and pressure shocks, damaging the internal gears. After installing the 60277674 motor, bleed the air from the supply and return lines before running the fan system under full load.
