• **Heavy-duty AT405846 variable piston fan motor tailor-made for John Deere E360LC, perfectly matched with A10VO45DFR/52R fan pump**
AT405846 hydraulic fan motor is custom designed for John Deere E330LC/E350LC/E360LC excavators. It converts adjustable hydraulic pressure oil into powerful rotary torque. Reliable variable speed performance ensures the cooling fan can automatically adjust speed under heavy-load rock excavation and long-hour continuous operation, preventing engine overheating.
• **Precision hardened piston & cylinder block assembly, stable torque output and fast solenoid response**
Alloy steel piston and cylinder block assembly adopts precision grinding and surface hardening process. The built-in solenoid valve can quickly change motor displacement according to engine temperature signal. Volumetric efficiency is kept at high level to guarantee stable fan speed regulation for cooling circuit.
• **High-rigidity ductile iron housing with stress relief treatment, excellent anti-vibration and pressure impact resistance**
Ductile cast iron housing after stress relief annealing eliminates internal residual stress. It can resist continuous heavy vibration and high pressure impact in quarry sites. The housing is not easy to deform, slowing down wear of internal piston, valve plate and bearing components and extending service life.
• **Optimized internal flow channel structure and upgraded FKM sealing assembly, good anti-cavitation & high temperature resistance**
Optimized internal flow path reduces oil turbulence and cavitation risk. FKM seal set delivers outstanding high-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.

FAQ 

Q1: Can AT405846 fan motor work with other brand fan pumps?
A1: It is originally matched with A10VO45DFR/52R fan pump for John Deere E360LC. If matched with other pumps, flow and pressure parameters must be recalculated. Mismatched parameters will lead to overheating or early damage of the motor.

Q2: What inspection items are required before installing AT405846 fan motor?
A2: Check hydraulic oil cleanliness, clean the hydraulic pipeline thoroughly, and test the output performance of the matched fan pump. Contaminated oil or abnormal pump pressure will cause overload and damage the internal piston components quickly.

Q3: What causes fan speed cannot rise after replacing AT405846 fan motor?
A3: Common reasons: air trapped in hydraulic circuit, clogged hydraulic filter, solenoid valve stuck, or insufficient pump output flow. Bleed air and check solenoid valve and hydraulic pressure step by step.

Q4: What is the difference between AT405846 fan motor and A10VO45DFR/52R fan pump?
A4: A10VO45DFR/52R is hydraulic power source which generates variable pressure oil. AT405846 fan motor is the actuator, converting hydraulic power into rotation to drive cooling fan. They are a complete matched cooling system set.

Q5: What maintenance requirements for AT405846 fan motor in mining working condition?
A5: Replace hydraulic oil and filter elements on schedule, keep hydraulic oil cleanliness at NAS7 level or better. Check shaft seal leakage and solenoid valve response every 1500 working hours.
