468-5121 crankshaft AS CAT spare part

Advantages

• Helps minimize vibrations and ensures the overall smooth operation of the engine
• Withstands high mechanical loads and rotational forces, ensuring reliable and continuous operation

1. Integrally forged steel blank delivers strong torsion resistance and fatigue resistance, suitable for mining impact working conditions.
2. Main journals and connecting rod journals are precision machined with stable wear-resistant layer, slowing bearing wear effectively.
3. Integrated timing gear with high tooth accuracy ensures precise timing transmission and reduces valve train failures.
4. Pre-assembled counterweights with factory dynamic balance calibration reduce engine vibration and extend service life.
5. Built-through lubrication oil passages provide even and stable oil supply for high-speed heavy-load operation.
6. OE standard dimension for direct replacement, no extra machining required.

FAQ 

Q1: Can 468-5121 replace 430-2593 directly?
A1: Not interchangeable. They differ in timing gear and counterweight structure.
Q2: Can the crankshaft be reused if timing gear teeth are slightly worn?
A2: If pitting, chipping or excessive wear appears on gear teeth, the whole crankshaft must be replaced instead of changing gear separately.
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 timing gear during crankshaft storage?
A4: Coat gear with anti-rust grease and wrap with protective film. Support the crankshaft on multiple points to avoid gear impact and bending.
