Product Description
- Part Number: 3932914
- Type: Crankshaft Main Bearing Kit
- Structure & Material: Steel back + aluminum-based/copper-lead alloy antifriction layer, surface anti-seizure coating, with locating tabs and oil grooves
- Function: Supports crankshaft rotation, forms lubricating oil film, reduces friction and wear between crankshaft and engine block, ensuring smooth power output
- Support & Friction Reduction: Acts as a sliding bearing between the crankshaft and engine block, withstands cyclic impact loads, and isolates metal contact via lubricating oil film to minimize friction loss.
- Lubrication & Cooling: Built-in oil grooves and holes guide oil to form a stable film, while carrying away frictional heat to prevent bearing burnout and crankshaft deformation.
- High Precision & Durability: Strictly controlled wall thickness tolerance and surface finish ensure concentric crankshaft operation; the alloy antifriction layer offers excellent fatigue and corrosion resistance, adapting to high-load construction machinery operation.
- OEM Compatibility: The kit includes all main bearings, with dimensions and locating structures perfectly matching Caterpillar original specifications, ideal for engine overhaul to restore crankshaft precision and oil pressure.
Suitable for powertrain overhaul and maintenance of corresponding Caterpillar engines, resolving issues such as bearing wear, burnout, low oil pressure, and engine noise. It is a core bearing component to ensure long-term stable engine operation.
