ZF 5838.300.223 LUBRICATION TUBE | OEM Genuine Part

Overview

The ZF 5838.300.223 LUBRICATION TUBE is a precision-engineered OEM genuine component designed to direct pressurized oil flow to critical bearing surfaces and gear meshes within heavy-duty ZF construction machinery transmissions. This tube sits inside the transmission housing, routing lubricant from the main oil gallery to the differential and axle assemblies. The SKU 5838.300.223 ensures consistent oil delivery, preventing metal-to-metal contact during high-load operations. Without this tube, internal components such as the 5838022003: REAR AXLE and 5838109001: DIFFERENTIAL would suffer from inadequate lubrication, leading to premature wear and costly downtime.

Symptoms of Failure

• Oil leaks near transmission housing: A cracked or corroded lubrication tube allows pressurized oil to escape, leaving puddles under the vehicle. This is a common long-tail search query for “ZF transmission oil leak from tube.”
• Gear slipping under load: Insufficient oil flow to the 0750117075: TAPER ROLLER BEARING causes bearing seizure, resulting in intermittent gear engagement and power loss.
• Overheating differential: When the tube fails, the 5838300128: DIFFERENTIAL HOUSING receives inadequate cooling, leading to thermal expansion and whining noises from the rear axle.
• Metal shavings in oil: A blocked or collapsed tube starves gears of lubrication, causing accelerated wear and contamination of the transmission fluid.

Technical Specifications

Compatibility

This lubrication tube is engineered for ZF WG180, WG200, and WG250 series transmissions commonly found in wheel loaders, excavators, and telehandlers. It also fits select ZF Ecomat and Ecolite models used in construction machinery. Always verify your transmission serial number before ordering. The tube interfaces directly with the 5838300128: DIFFERENTIAL HOUSING and the 5838022003: REAR AXLE assembly.
