1. Product Positioning: The "Power Transmission Core" of Construction Machinery
The C18 crankshaft 468-5119 is a critical transmission component for construction machinery (such as excavators, loaders, and generator sets). It directly impacts engine power transmission efficiency and overall machine operating stability, and is a crucial component for preventing unexpected mechanical failures and ensuring operational efficiency.
2. Core Function and Compatible Models
Compatibility: Designed specifically for Caterpillar C18 series engines, it is widely compatible with excavators such as the Caterpillar 349D2 and 352F, as well as loaders such as the 966K and 972K. It is also compatible with some third-party construction machinery of the same specifications. (Please provide your model number before placing an order, and Ningbo Qiuning Trading will assist in verifying compatibility.)
Core Value: It transmits engine power to various actuators through precision transmission, reducing power loss. Made of high-strength alloy, it can withstand the torque shocks of high-load operations, reducing downtime and repair costs caused by crankshaft failure.

IV. Correct Installation and Usage
Pre-installation Preparation:
Inspect the crankshaft's appearance (for cracks, scratches, or deformation), clean the mounting surface of the machine from oil and debris, and verify the crankshaft journal dimensions and compatibility with the equipment's bearing seat.
Prepare appropriate installation tools (torque wrench, bearing puller, etc.). This is recommended for qualified equipment maintenance personnel.
Installation Specifications:
Apply specialized assembly grease as specified in the equipment maintenance manual to prevent initial wear caused by dry friction.
When tightening bolts, adhere to the "diagonal tightening" principle. The torque value strictly complies with the engine's technical specifications (typically 180-220 N·m, refer to the equipment manual for specific details) to prevent overtightening and damage to the crankshaft.
First-Time Use Precautions:
After installation, start the machine and idle for 10-15 minutes to check whether the oil pressure is stable (normal range: 0.3-0.6 MPa).
Avoid full-load operation for the first time. It is recommended to run-in the machine at 70% load for the first 50 hours to reduce initial fatigue on the crankshaft.
5. Key Tips for Extending Service Life
Daily Monitoring: During operation, pay attention to engine noise (abnormal noise may indicate crankshaft bearing wear) and vibration frequency. Immediately stop the machine for inspection if any abnormality is detected to prevent further damage.
Maintenance: Replace engine oil with API CK-4 grade oil according to the equipment cycle. Change the oil filter every 200 hours to prevent impurities from entering the crankcase and causing poor lubrication. Regularly clean the crankcase ventilation valve to prevent excessive crankcase pressure from causing oil leaks.
Storage and Protection: Unused crankshafts should be coated with anti-rust oil, wrapped with moisture-proof film, and stored in a dry and ventilated environment. Avoid direct sunlight, humidity, or high temperatures, which can cause corrosion and performance degradation.
VI. User Guarantee
Quality Advantage: The crankshaft is made of 42CrMo high-strength alloy steel, precision forged, and high-frequency quenched, achieving a surface hardness of HRC 58-62. Its fatigue strength and wear resistance meet international standards for construction machinery parts.
After-Sales Support: We offer a 3-6 month warranty. Ningbo Qiuning Trading provides free returns and exchanges for non-human quality issues (such as cracks or deformation) during the warranty period. We also provide remote technical guidance, assisting with installation and repair questions using videos and drawings.
Payment Convenience: We accept international payment methods such as T/T and L/C. Large orders can be negotiated to reduce purchasing pressure.
