Original Excavator Fan Guard 1215514641 for ISUZU Engine 6BG1

This high-strength heavy-duty fan guard assembly (Engine Fan Guard) is an Isuzu original high-quality power peripheral protection component, with the original core part number 1215514641. This high-end safety protection unit is specially designed for various high standard hydraulic excavators equipped with the classic Isuzu 6BG1 inline six cylinder engine (such as Hitachi ZAXIS200, ZX210-5G and other 20 ton industry absolute flagship models). The product is based on first principles optimization of the fluid dynamics intake and exhaust grille architecture, providing absolute physical and mechanical protection, preventing external foreign objects from entering the high-speed rotating fan area, while ensuring that the engine core cooling flow field is in a low entropy, efficient and absolutely smooth state. The physical dimensions of the product packaging are approximately 680mm × 660mm × 120mm, with an overall net weight of approximately 4.2kg, perfectly aligned in place.

"Extreme power-off and dust-free cleaning (core avoidance pit): Before installation, the engine must be forcibly turned off, the key must be removed, and the main power switch of the entire vehicle must be cut off. It is strictly prohibited to work recklessly when the fan is not absolutely stopped. Use a wire brush to thoroughly scrape off rust and mud on the mounting holes of the frame and water tank bracket, ensuring that the reference surface is extremely flat.

Torque tightening and absolute clearance verification: During installation, high-strength anti loosening bolts with spring washers from the original factory must be rigidly matched. All fastening bolts must be tightened symmetrically and in stages using torque wrenches in strict accordance with the original factory standards. After tightening, the fan must be manually rotated several times by hand, and the physical gap between the fan blades and the protective cover mesh must be verified in three-dimensional cross validation to be no less than 15-20mm, to prevent slight deformation from causing scratches and jamming after ignition."
