description

MSF16N fan piston motor is the core actuator of cooling hydraulic circuit for construction machinery. Driven by pressurized hydraulic oil supplied by matched fan pump, it converts hydraulic power into rotary power to drive cooling fan and dynamically adjust fan speed for stabilizing engine operating temperature. Internal piston, cylinder block, valve plate, bearing and control valve adopt precision grinding and surface hardening technology, maintaining stable torque output and low internal leakage under medium-high working pressure and frequent variable load. During long-time excavation and loading operation, the motor housing can withstand cyclic pressure impact and high oil temperature. The housing is made of high-strength cast iron with stress relief annealing treatment, featuring high rigidity and anti-deformation performance. All friction mating parts are precision processed to reduce abrasive wear caused by tiny solid particles in hydraulic oil. Each fan motor passes strict hydraulic bench inspection before shipment, including torque test, speed test, starting performance test, durability test, internal leakage test and noise detection, ensuring high interchangeability.

advantage

・MSF16N axial piston hydraulic fan motor, aftermarket replacement, perfectly matched with supporting fan pump for construction machinery cooling system
MSF16N hydraulic fan motor is designed for construction machinery cooling circuit. It converts hydraulic pressure into rotary torque to drive cooling fan. Stable torque output ensures fan can adjust speed flexibly under continuous excavation and loading operation, preventing engine overheating.
・Compact piston and cylinder block assembly, stable torque output and low flow pulsation
Alloy steel piston and cylinder block adopts precision grinding and surface hardening process. It maintains steady torque output under variable inlet pressure. Volumetric efficiency stays high to guarantee consistent fan rotation for cooling circuit.
・Full hydraulic bench inspection before delivery, high interchangeability for direct plug-and-play replacement
Each MSF16N fan motor passes torque, speed, starting performance and durability hydraulic bench test. All mounting dimensions, port positions and spline shaft match the original specifications. Direct installation without modification, shortening equipment downtime and cutting maintenance cost.
・Lightweight structure, fast speed response to protect radiator and engine assembly
This fan motor adopts lightweight compact design and rapid response to pressure changes. It provides stable rotary power for cooling fan. It maintains cooling hydraulic system operating normally, preventing radiator overheating caused by insufficient fan torque or speed attenuation, ideal replacement for overhaul and daily maintenance of construction machinery.

FAQ 

Q1: What machine types is MSF16N fan motor suitable for?
A1: It is widely applied on multiple medium-sized excavators of XCMG, Sany, LiuGong. Confirm installation dimension and oil circuit before purchase.

Q2: What is the outstanding feature of MSF16N?
A2: Small displacement with compact outline, it saves installation space while maintaining stable torque output, fits limited engine compartment layout.

Q3: Why does the fan rotate slowly after installing MSF16N?
A3: Check if hydraulic oil viscosity is correct and whether air remains inside the circuit. Insufficient supply pressure from fan pump is another common cause.

Q4: What inspection should be carried out before installation?
A4: Check the motor shaft for damage, inspect sealing surfaces, and clean the hydraulic pipeline to stop solid particles entering the motor.

Q5: How to reduce wear for small-displacement fan motor?
A5: Keep hydraulic oil clean, avoid frequent sharp pressure surges. Carry out regular inspection of oil quality and seals.
