Overview
The ZF 2093.322.032 SPUR GEAR is a critical power-transfer component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part directly engages with the countershaft to manage torque distribution and rotational speed within the gear train. As a precision-machined gear, it ensures smooth synchronization between input and output shafts. The SKU 2093.322.032 is specifically designed to maintain the exacting tolerances required for heavy-duty industrial applications, reducing vibration and mechanical noise during operation. It sits within the main gear cluster, interfacing directly with the 2093101052 HOUSING and the 2093298063 TRANSMISSION HOUSING to form a sealed, lubricated assembly.
Symptoms of Failure
- Whining or grinding noise during gear engagement: A worn spur gear produces a distinct high-pitched whine or metallic grinding sound, especially under load or during acceleration. This indicates tooth surface pitting or chipping.
- Intermittent gear slipping under heavy torque: When the gear teeth lose their profile due to fatigue, the transmission may momentarily slip out of gear, causing a sudden loss of power to the drivetrain.
- Metal particles in transmission fluid: Inspecting the oil pan or filter often reveals metallic debris or glitter, a direct sign that the spur gear’s hardened surface is deteriorating and shedding material.
- Hard shifting or gear clash: Worn gear teeth prevent smooth synchronization, leading to a noticeable clash or resistance when moving the shift lever between positions.

Compatibility
This spur gear is a direct-fit OEM replacement for the following ZF transmission models: WG100, WG130, and WG131. It is also compatible with certain variants of the WG180 and WG200 series that share the same gear train architecture. Always verify the tooth count and spline configuration against your existing part. For proper installation, ensure the 2093301069 TRANSMISSION HOUSING is free of cracks, and secure the assembly using the 4475280015 SCREW PLUG to prevent lubricant leakage.

Frequently Asked Questions
Q: Can I replace the ZF 2093.322.032 spur gear without removing the entire transmission?
A: In most WG100/WG130 applications, the spur gear is accessible after removing the side cover and the 2093301033 COVER. However, full transmission removal is recommended to inspect all bearings and seals.
Q: What is the expected service life of this spur gear under normal operating conditions?
A: With proper lubrication and no contamination, the case-hardened steel construction typically delivers 8,000–12,000 operating hours before measurable wear appears. Always replace the 0634304731 O-RING during installation to prevent fluid ingress.
Q: Does this part include the necessary fasteners or seals?
A: No, the spur gear is sold individually. You will need to order the 0636015073 HEXAGON SCREW and 4475280150 SCREW PLUG separately for a complete rebuild.
