34333-12201 Turbocharger Oil Drain Tube for Mitsubishi S6K

34333-12201 Turbocharger Oil Drain Tube for Mitsubishi S6K

The 34333-12201 turbocharger oil drain tube is a replacement engine lubrication component for Mitsubishi S6K diesel engine applications. It is commonly identified in replacement parts catalogs as a turbocharger oil return or drain pipe and is associated with selected Caterpillar 3066 engine installations.

The tube forms part of the turbocharger lubricating oil circuit. Its purpose is to provide a return passage for engine oil leaving the turbocharger bearing housing. The replacement tube must match the original pipe routing, flange connections and engine installation arrangement.

Mitsubishi 34333-12201 and CAT 5I-7557 Reference

Replacement parts suppliers list Mitsubishi reference 34333-12201 alongside Caterpillar part number 5I-7557. Caterpillar identifies 5I-7557 as a Turbocharger Oil Lines Pipe for applicable excavator engine arrangements.

The reference relationship should be confirmed against the original part and its installation configuration before ordering. A separate turbocharger oil pipe, CAT 5I-8060, is listed in the related oil lines assembly and should not be treated as an interchangeable reference for this component.

Caterpillar Excavator Applications

CAT 320B | 320B L | 320B N | 320C | 320C L | 318C | 319C | 321C | 320D | 320D L

These model families appear in Caterpillar compatibility records for the associated 5I-7557 turbocharger oil pipe. Actual applicability depends on the engine arrangement and machine serial number. The list should be used as a starting point for identification rather than a guarantee of fitment across every production version.

Turbocharger Oil Return Pipe Installation

A turbocharger oil drain line should maintain a clear return path for lubricating oil. Incorrect routing, damaged flange surfaces, blocked passages or leaking connections may interfere with proper oil drainage and turbocharger operation.

Before installation, compare the original and replacement tubes, especially the flange arrangement, mounting points and overall shape. Inspect the related gaskets, fasteners and connection surfaces, and replace installation hardware when required by its condition.
