Caterpillar Advanced Efficiency Hydraulic Filter | Part 348-1862

Product Overview

The Caterpillar 348-1862 Hydraulic and Transmission Filter is an advanced efficiency element designed to provide superior contamination control for your heavy equipment. Featuring Advanced Efficiency media, this filter is engineered to capture smaller particles than standard filters, protecting sensitive hydraulic components like pumps and valves from abrasive wear. Its robust construction includes acrylic beading to prevent pleat bunching and an integrated seal that ensures a strict barrier between clean and dirty fluid.

This filter is a critical maintenance component for a wide range of Cat Skid Steer Loaders (236D, 242D, 246D, 262D), Compact Track Loaders (259D, 279D, 289D), and Multi-Terrain Loaders (257D, 277D, 287D). It is also compatible with equipment powered by C3.3B, C4.4, and C6.6 engines, as well as several Asphalt Pavers and D3K2, D4K2, and D5K2 Track-Type Tractors. Using genuine-specification filters like the 348-1862 helps maintain system pressure and prevents the sluggish performance or "chatter" often caused by fluid contamination.
