448-2620 crankshaft AS CAT spare part

Advantages

• Manufactured with precision machining, heat treatment, and balancing processes for durability and optimal performance.
• Counterweights reduce vibration and ensure smooth operation.

1. Full-process CNC precision machining ensures accurate position and dimension of signal pickup ring, stable signal for crankshaft position sensor.
2. Forged steel blank with good toughness and alternating impact resistance, suitable for frequent start-stop conditions of small and medium construction machinery.
3. High precision grinding on main journals and connecting rod journals reduces bearing friction loss and extends overhaul interval.
4. Integrally formed counterweights with factory dynamic balance calibration reduce engine vibration and protect electronic components.
5. Built-through lubrication oil passages deliver smooth oil flow for stable lubrication under idling and variable load conditions.
6. OE standard assembly dimension for direct replacement without extra machining, compatible with electronic engine calibration.

FAQ 

Q1: Can 448-2620 interchange with ordinary C4.4 crankshaft without signal pickup zone?
A1: Not interchangeable. Ordinary crankshaft lacks sensor pickup structure, ECU cannot read speed signal.
Q2: Can the crankshaft be used if the signal pickup ring has light scratches?
A2: Light scratches that do not interfere with signal reading are acceptable. Replace it if dents, deformation or chipping occur.
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 pickup area during storage?
A4: Coat the signal ring with anti-rust oil and wrap with soft protective film. Support on multiple points to prevent impact and deformation.
