ZF 5838.300.101 BUSH | OEM Genuine Part

Overview

This genuine OEM ZF 5838.300.101 BUSH is a precision-engineered component designed to serve as a critical wear surface within the differential and axle assembly of heavy-duty construction machinery transmissions. The bushing reduces friction between rotating shafts and stationary housings, ensuring precise alignment and load distribution under extreme torque conditions. As a factory-spec replacement, the SKU 5838.300.101 directly restores factory tolerances and prevents premature wear on adjacent components such as the 5838109012: DIFFERENTIAL and the 2093209023: DIFFERENTIAL assembly. Without this bushing, gear mesh accuracy degrades rapidly, leading to costly drivetrain repairs.

Symptoms of Failure

When the ZF 5838.300.101 bushing wears beyond service limits, operators will notice distinct mechanical issues. 1. Driveline vibration under load – excessive clearance allows the shaft to wobble, creating harmonic vibrations felt through the chassis. 2. Metallic grinding noises from the axle housing – worn bushings permit metal-on-metal contact between the shaft and housing, producing a distinct scraping sound during turns. 3. Oil seepage around the differential housing seal – a worn bushing misaligns the shaft, distorting the seal lip and causing gear oil to weep onto the housing. 4. Intermittent gear slipping in forward gears – when the bushing fails, the 0750117075: TAPER ROLLER BEARING loses its preload, allowing the differential gears to momentarily lose engagement.

Technical Specifications

Compatibility

This bushing is engineered for ZF heavy-duty powershift transmissions commonly found in wheel loaders, graders, and excavators. It is a direct fit for the ZF WG180, WG200, and WG211 series, as well as the ZF 4WG-200 and ZF 6WG-250 transmission families. The bushing seats inside the 5838300626: DIFFERENTIAL HOUSING, where it supports the axle shaft and maintains concentric alignment for the differential gears. Always verify your transmission model code before ordering.

Frequently Asked Questions

Q: How do I know if the 5838.300.101 bushing is the correct replacement for my ZF transmission?
A: Check your transmission model plate. This bushing is standard in WG180, WG200, and WG211 series. If your machine uses a 4WG-200 or 6WG-250, measure the axle shaft outer diameter (45 mm) to confirm fitment.

Q: Can I reuse the old bushing if it shows only minor wear?
A: No. Even minimal wear alters the clearance tolerance, leading to accelerated damage of the 0750117075: TAPER ROLLER BEARING and differential gears. Always replace with a new OEM bushing during overhaul.

Q: What other parts should I replace at the same time as this bushing?
A: It is strongly recommended to replace the 5838300811: THRUST WASHER and 5838300818: THRUST WASHER simultaneously, as they share the same wear cycle and clearance specifications.
