Overview
The ZF 5838.300.141 RING is a precision-engineered internal component designed to maintain gear alignment and load distribution within heavy-duty construction machinery transmissions. Positioned within the differential assembly, this OEM genuine ring acts as a critical spacer and wear surface, ensuring consistent torque transfer under extreme operational stress. The SKU 5838.300.141 is manufactured to ZF’s exacting tolerances, making it essential for restoring factory-spec performance in high-hour equipment. When paired with a properly functioning 5838022003: REAR AXLE, this ring helps prevent axial play that can compromise drivetrain integrity.
Symptoms of Failure
- Oil leaks near the differential housing – A worn 5838.300.141 ring can cause seal misalignment, leading to gradual fluid seepage that contaminates the 5838109001: DIFFERENTIAL assembly.
- Intermittent gear slipping under load – When the ring loses its dimensional stability, gear engagement becomes inconsistent, particularly during heavy excavation or lifting cycles.
- Metallic grinding noises from the axle center – Excessive clearance from a degraded ring allows metal-on-metal contact between the 0750117075: TAPER ROLLER BEARING and adjacent components.
- Vibration during straight-line travel – A warped or cracked ring creates rotational imbalance, which accelerates wear on the 5838300128: DIFFERENTIAL HOUSING and its mating surfaces.

Compatibility
This ring is engineered for ZF’s WG180, WG200, and WG310 series transmissions commonly found in wheel loaders, telehandlers, and graders. It also integrates with the APL-300 and APL-400 axle families. For proper installation, verify that the 0631329086: SPRING PIN is correctly seated to prevent rotation of the ring during operation. The 5838.300.141 ring works in conjunction with the 5838300129: THRUST WASHER and 5838300130: THRUST WASHER to manage axial loads, while the 5838300131: AXLE BEVEL GEAR transfers rotational force through the assembly. Always inspect the 5838300132: COMPENS. STUB AXLE and 5838300133: COMPENS. STUB AXLE for wear when replacing this ring.
