ZF 0730.104.241 WASHER | OEM Genuine Part

Overview

The ZF 0730.104.241 WASHER is an OEM genuine shim component engineered for precision load distribution within heavy-duty construction machinery transmissions. This hardened steel washer sits between the planetary gear carrier and the sun gear shaft, maintaining critical axial clearance in the rotating assembly. As part number 0730.104.241, it prevents metal-to-metal contact under extreme torque loads, ensuring consistent oil film thickness between moving parts. When installed alongside the 4143101009: HOUSING and 4143301025: HOUSING, this washer forms a sealed boundary that directs hydraulic fluid through the clutch pack circuits.

Symptoms of Failure

• Transmission oil seepage at the bell housing – A worn 0730.104.241 washer allows lateral movement, breaking the seal between the 0634313603: O-RING and the housing face, leading to visible drips after shutdown.
• Gear engagement delay in forward/reverse – Reduced washer thickness increases end-play, causing the clutch piston to travel further before engagement, resulting in a 1–2 second lag when shifting.
• Metallic grinding noise during low-speed maneuvering – As the washer surface degrades, the sun gear contacts the housing directly, producing a distinct high-pitched chatter under 5 mph.
• Erratic pressure readings on the main regulator valve – Excessive axial play from a collapsed washer causes the 4475280018: SCREW PLUG to back out slightly, altering hydraulic backpressure.

Technical Specifications

Compatibility

This washer is dimensionally validated for the following ZF transmission families used in wheel loaders, graders, and dozers: WG180, WG200, WG210, and WG250 series. It also fits the 4WG-200 and 6WG-250 variants where the sun gear shaft uses a 42 mm journal. Always verify axial clearance during rebuild; the 0730.104.241 is typically used in stacks of 1–3 washers to achieve 0.10–0.25 mm end-play.
