ZF 0730.200.270 THRUST WASHER | OEM Genuine Part

Overview

The ZF 0730.200.270 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 gear sets and stationary housings, this thrust washer absorbs end-play forces that would otherwise cause metal-on-metal contact and premature wear. The SKU 0730.200.270 is specifically machined to exact OEM tolerances, ensuring consistent oil film distribution and stable gear alignment under high-torque conditions in construction machinery. When installed alongside a 5838109012: DIFFERENTIAL, this washer prevents axial displacement that can lead to differential gear misalignment.

Symptoms of Failure

• Transmission whining noise under load — A worn 0730.200.270 thrust washer allows gear end-play, producing a distinct metallic whine during acceleration or uphill operation. This is a common long-tail search query for “ZF transmission whining noise when accelerating.”
• Intermittent gear slipping in forward gears — As the washer loses thickness, axial clearance increases, causing clutch packs to partially disengage. Operators often search for “ZF transmission slipping in forward gears construction equipment.”
• Metal particles in transmission oil — Flaking or spalling of the hardened steel washer surface introduces ferrous debris into the lubrication system. This symptom triggers searches like “metal shavings in ZF transmission oil after rebuild.”
• Hard shifting between ranges — Excessive end-play from a collapsed thrust washer prevents smooth engagement of planetary gear sets, leading to “ZF transmission hard shifting between ranges” queries.

Technical Specifications

Compatibility

This thrust washer is a direct OEM replacement for ZF WG-series transmissions commonly used in wheel loaders, telehandlers, and graders. Compatible models include the ZF WG180, ZF WG200, and ZF WG210 series. It also fits select ZF 4WG-200 and ZF 4WG-210 powershift transmissions. When servicing these units, always inspect the mating 0750117075: TAPER ROLLER BEARING for wear, as bearing preload directly affects washer life. Additionally, verify the condition of the 2093209023: DIFFERENTIAL assembly, as a damaged differential can cause uneven loading on the thrust washer. The 5838300626: DIFFERENTIAL HOUSING must also be checked for scoring or warping to ensure proper washer seating.

Frequently Asked Questions

Q: How do I know if my ZF 0730.200.270 thrust washer is worn out?
A: Measure the washer thickness with a micrometer. If it measures below 2.50 mm (original is 2.70 mm), replacement is required. Also check for uneven wear patterns or scoring on the face.

Q: Can I reuse the old thrust washer during a transmission rebuild?
A: No. The 0730.200.270 is a wear item that should always be replaced with a new OEM part during any major transmission service. Reusing it risks premature failure and damage to the differential housing.

Q: Does this thrust washer require lubrication before installation?
A: Yes. Apply clean transmission fluid or assembly lube to both faces of the washer before installation to prevent dry start-up wear. Ensure the mating surfaces on the differential housing are free of burrs.
