ZF 0730.150.238 THRUST WASHER | OEM Genuine Part

Overview

The ZF 0730.150.238 THRUST WASHER is a precision-engineered OEM genuine component designed to manage axial loads and maintain critical clearances within ZF heavy-duty transmissions. Positioned between rotating shafts and stationary housings, this washer absorbs end-play forces that would otherwise cause metal-on-metal contact. The SKU 0730.150.238 is commonly found in the clutch pack or planetary gear set area, where it prevents scoring on adjacent surfaces. When installed alongside a TRANSMISSION HOUSING, it ensures the shaft assembly remains properly centered under high torque conditions.

Symptoms of Failure

When the ZF 0730.150.238 thrust washer wears beyond tolerance, operators often notice these specific failure modes:

• Transmission gear slipping under load – Worn washers allow excessive shaft movement, causing clutch packs to lose engagement pressure.
• Metallic grinding noise during gear changes – Thinned washers permit gear teeth to contact housing walls, producing a distinct scraping sound.
• Low oil pressure warnings – Debris from a disintegrating washer can clog oil passages, reducing hydraulic pressure to clutches and valves.
• Visible metal particles in transmission fluid – Flakes or shavings on the dipstick or drain plug indicate advanced washer degradation.

Technical Specifications

Compatibility

This thrust washer is engineered for ZF power-shift transmissions used in construction machinery. It is a direct fit for the WG180, WG200, and WG250 series, as well as the 4WG200 and 6WG200 variants. The washer also appears in certain Ecomat and Ergopower models where axial thrust loads are present. For proper installation, ensure the mating HOUSING bore is clean and free of burrs. Always replace the SCREW PLUG and OIL LEVEL GAGE seals when servicing this area to prevent leaks.
