1125233470 Excavator 6UZ1 diesel Generator Idle Gear

Part number 1125233470 is the original idler gear provided by ISUZU (Isuzu) for the 6UZ1 series large displacement diesel engine. This component is a key transmission gear in the engine timing system or accessory drive system, used to transmit power, adjust gear clearance, or change transmission direction. Its universal models cover specific large equipment equipped with 6UZ1 engines, usually mining power units, large generator sets, or specific models of mining machinery. As the core transmission component of the original factory, its tooth profile, module, and installation aperture are precisely meshed with the crankshaft gears, camshaft gears, and other components of the engine

This product is an idler wheel made of high-strength alloy steel casting/forging, with a dark gray disk shape as a whole. The surface has a rough texture that has not been finely ground after casting, presenting a strong industrial component feel. The outer edge processing has a uniform and sharp circle of straight or helical teeth for precise meshing. The center is a precision machined mounting hole with a brass colored wall, indicating that it is pre pressed with a copper alloy liner or shaft sleeve to enhance wear resistance and lubrication between it and the mounting shaft. This is a typical design of heavy-duty gears. Five large irregular weight reducing holes are evenly distributed on the gear body, achieving effective lightweighting while ensuring structural strength. Its tooth surface and root have undergone heat treatment, resulting in high hardness and fatigue resistance, making it the core "bridge" component in the internal gear transmission system of the engine.

Installation specifications: 1 Cleaning and Inspection: Before installation, it is necessary to thoroughly clean the installation shaft, gear inner hole bushings, and all meshing gear tooth surfaces with cleaning agents to ensure that there are no impurities. Check that there are no bumps or burrs on the surface of the new idler gear teeth. 2. Lubrication: Apply a sufficient amount of engine assembly lubricant or designated gear grease to the gear liner and all tooth surfaces. 3. Alignment installation: Insert the idler gear (1125233470) smoothly into the installation shaft, ensuring it is fully in place. Special tools and adjusting shims of specified thickness are usually required to precisely control the axial clearance and meshing side clearance. 4. Torque tightening: Use a torque wrench to tighten the fixing bolts or nuts to the specified torque.
