Custom 274-4553 Transmission Clutch Friction Disk Replacement for Cat Loaders Suppliers, Factories

274-4553 / 2744553 is a Caterpillar (CAT) original equipment replacement planetary system wet clutch friction plate, applied for small construction machinery power shift transmissions. It is mainly used in the planetary assembly of industrial loaders such as the 415F2 and backhoe loaders such as the 420XE and 427F2.

Product Description

Product Overview

Product Name: Clutch friction disc
Part Number: 274-4553, 2744553 (CAT OE)
Product Type: Transmission clutch friction disc
Fitment: Planetary gear transmission systems
Temperature Range: -30℃ ~ +130℃

Main Application: Specifically designed for CAT 415F2 industrial loaders, 420XE/427F2 backhoe loaders, and 414F. Compatible with heavy-duty engines including C3.4B, C4.4, and C7.1 series.

Packaging: Supplied in standard industrial cartons. Support for customized packaging solutions is available.

Important Note: This friction disc is an external spline friction plate. It must be used in pairs with internal spline steel plates of the same series (such as 274-4554). During assembly, it is critical to control the total thickness according to original specifications to ensure proper transmission performance.
