466-4921 Crankshaft AS CAT spare part

Advantages

1. Integrally forged steel blank resists alternating load, suitable for frequent start-stop and variable load in earthmoving jobs.
2. Main journals and connecting rod journals are precision machined with wear-resistant treatment, slowing bearing wear effectively.
3. CNC machined signal pickup ring with stable position accuracy ensures continuous and reliable speed signal.
4. Integrally formed counterweights with factory dynamic balance calibration reduce engine vibration and protect electronic parts.
5. Built-through lubrication oil passages deliver smooth oil flow, stable lubrication under idle and heavy load switching.
6. OE standard assembly dimension for direct replacement without extra machining, compatible with engine calibration.

• It is designed to withstand the rigorous conditions and demands of continuous operation
• Machined with precision to achieve the necessary balance and ensure accurate conversion of motion
• Undergoes careful balancing to minimize vibrations, ensuring smooth operation and reducing wear on other engine components
• It is designed to be robust and capable of handling high rotational speeds, continuous operation, and the stresses and loads generated during power generation

FAQ 

Q1: Can 466-4921 interchange with 448-2620 directly?
A1: Not interchangeable. They differ in signal ring, journal size and crank throw, fit different equipment versions.
Q2: Can light scratches on signal ring affect operation?
A2: Scratches that do not damage the sensing profile and stay within tolerance are acceptable. Replace it if deformed or chipped.
Q3: Which spare parts should be renewed together with crankshaft?
A3: Main bearings, connecting rod bearings, thrust washers, front and rear oil seals and main bearing bolts are recommended.
Q4: How to protect the signal ring during storage?
A4: Coat the signal ring with anti-rust oil, wrap with soft protective film and support on multi-point fixture to avoid impact deformation.
