Original Excavator Fan Blade Protective Net 1215111141 for ISUZU Engine 6BG1

This premium heavy-duty engine Fan Blade Protective Net features the genuine part number 1215111141 (1-21511-114-1). This high-end safety protection unit is deeply engineered for various mainstream hydraulic excavators (such as 12 to 20-ton Hitachi and Sumitomo models) powered by the classic Isuzu 6BG1 industrial inline-6 engine. Based on first principles, it is constructed from premium thickened anti-vibration alloy steel wire via fully automated mesh welding, with an optimized fluid-resistance design. It delivers extreme resistance against physical impacts and high-frequency thermal vibrations, seamlessly countering high-heat impulse flow fields inside the pump bay to ensure absolute low entropy and human-machine physical isolation safety when the cooling fan rotates at high speeds. The product packaging physical dimensions are approximately 620mm × 620mm × 45mm, with a net weight of around 2.15kg.

"Extreme Clearance Verification & Flatness Correction (Core Pitfall Avoidance): Installation must only proceed after the engine has completely cooled down. After removing the old part, completely clean the bracket mounting surfaces. During assembly, rigidly verify the physical safety clearance between the net, the fan blade tips, and the pulley (ensure a full-circumference clearance of ≥ 20mm). Any mesh deformation or misalignment will trigger fatal black-box rubbing at the instant of startup, causing lightning-fast fan blade shattering.

Stress-Free Alignment & Anti-Loosening Fastening: Position the new protective net smoothly, ensuring the grid streamline direction is perfectly correct. It is mandatory to pair it with brand-new genuine anti-vibration rubber gaskets and lock bolts (never reuse aged old parts). Use a precise torque wrench to execute a cross-pattern, multi-stage uniform tightening strictly matching OEM torque specifications, preventing local stress concentration deformation caused by one-sided over-tightening."
