・307-3063 gear hydraulic fan motor, OEM replacement, perfectly matched with supporting fan pump for CAT426F backhoe loader cooling system
307-3063 hydraulic fan motor is custom fitted for CAT426F backhoe loader cooling circuit. It converts hydraulic pressure into rotary torque to drive cooling fan. Stable torque output ensures fan can adjust speed flexibly under continuous earthmoving and loading operation, preventing engine overheating.
・Precision hardened alloy steel gear pair, stable torque output and low running noise
Alloy steel gear pair adopts precision hobbing 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.
・Optimized internal flow channel structure and upgraded FKM sealing assembly, good anti-cavitation & medium temperature resistance
Optimized internal flow path reduces oil turbulence and cavitation risk. FKM seal set delivers outstanding medium-temperature and hydraulic oil aging resistance. It effectively prevents internal and external oil leakage, avoiding premature component wear caused by oil contamination, minimizing unexpected machine downtime.
・Compact lightweight design, convenient installation and maintenance to protect radiator and engine assembly
This 307-3063 fan motor adopts compact lightweight structure, easy for disassembly and maintenance. It provides stable rotary power for cooling fan. It maintains cooling hydraulic system operating normally, preventing radiator overheating caused by insufficient fan torque or unstable rotation, ideal replacement for overhaul and daily maintenance of CAT426F backhoe loader.

FAQ 

Q1: What machine models can 307-3063 fan motor fit?
A1: Mainly for CAT426F backhoe loader, also interchangeable for CAT415F,420F,427F,428F F-series backhoe loaders. Confirm part number before purchase.

Q2: What is the main advantage of gear type fan motor on F-series backhoe loader?
A2: Small footprint, simple structure and lower failure rate. It is well suited for medium-load digging, backfilling and road maintenance jobs.

Q3: What causes the fan to rotate intermittently after motor replacement?
A3: The common reason is air trapped in hydraulic circuit, or insufficient oil supply caused by blocked filter. Complete air bleeding and filter replacement can solve most of this issue.

Q4: How to check whether the gear pair inside this motor is worn?
A4: Check external leakage and monitor fan speed under load. If speed drops sharply under load without pressure change, internal gear wear is highly suspected.

Q5: What maintenance tips to extend service life of this gear fan motor?
A5: Keep hydraulic oil clean, avoid long-time overpressure operation. Inspect seal leakage and abnormal noise every 1000 working hours.
