• High-strength cast alloy construction. Formed by precision casting and stress-relief annealing treatment. Outstanding structural rigidity and impact resistance. Effectively disperses cyclic vibration load generated by fan high-speed rotation. Not easy to deform or crack under long-time high-temperature vibrating environment, keeps stable supporting performance continuously.
• Precision machining of mounting holes. Flange hole positions, aperture and thread are strictly machined according to OE drawings. Guarantees good concentricity after installation, reduces fan shaking and eccentric wear. Minimizes extra vibration transferred to fan motor and adjacent parts.
• Strong adaptability to harsh construction environments. Anti-rust protective coating is applied on all surfaces. It can withstand dust, mud, temperature fluctuation and continuous vibration at job sites. Reduce the risk of rusting, corrosion and fatigue fracture during long service cycles.
• Strict multi-stage inspection before shipment. Each bracket is checked for dimension accuracy, casting defect inspection and thread integrity test. Surface finish and flatness are fully verified. Consistent dimensional accuracy batch by batch. Non-conforming products are eliminated before packing.
• Stabilize the whole cooling assembly. Reliable supporting structure reduces vibration transmission. Protect fan motor, oil seals and bearings from excessive eccentric load. Prevent secondary damage and extend service life of the entire cooling package.

FAQ 

Q1: Which machine does 200-3313 fan motor mount fit? Can it replace other part numbers?
A1: It is specially designed for CAT345C excavator C11 engine cooling system. Not universal for other CAT models. Mismatched brackets may cause fan shaking, concentricity deviation, crack and damage to fan motor. Please carefully verify machine model and OEM part number before purchase.

Q2: What tests are performed before shipment?
A2: Every fan motor mount is 100% inspected. Tests include dimension check, casting flaw detection, thread inspection and flatness verification. Simulated vibration assessment to guarantee stable performance after installation.

Q3: What is your warranty, and what is excluded?
A3: 12-month warranty under correct installation, proper torque and normal operation. Warranty excludes damage from over-tightened bolts, violent impact, welding modification, overload vibration and poor maintenance.

Q4: Is special adjustment required after installation?
A4: Precisely machined according to OE dimensions, direct installation normally. After fitting, check fan runout and tighten bolts to specified torque. If severe shaking exists, recheck concentricity of fan assembly.
