Thrust plate for Caterpillar 330D

The thrust plate 246-3150 functions as a component within the crankshaft assembly of the Caterpillar 330D engine. Its primary purpose is to control the axial clearance of the crankshaft, limiting lateral movement within the engine block. By absorbing thrust forces generated by the transmission and other drivetrain components, the plate prevents the crankshaft from shifting, which protects the main bearings and internal engine surfaces from contact and accelerated wear.

This component is compatible with the Caterpillar 330D excavator. It is associated with the crankshaft group 164-6148. Proper installation ensures the crankshaft maintains its intended position during operation, which is necessary for the mechanical integrity of the engine assembly.

In internal combustion engines, thrust plates or thrust washers are used to manage the end play of rotating shafts. They provide a bearing surface that supports the axial loads that occur during the operation of the engine, ensuring that the rotating assembly remains aligned and that the clearance between moving parts stays within the manufacturer's specified tolerances.
