Overview
The ZF 2093.368.105 SPUR GEAR is a precision-engineered component designed for the gear train assembly within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers rotational force between parallel shafts, ensuring smooth power delivery and load distribution under heavy-duty operating conditions. Positioned within the countershaft cluster, the spur gear (SKU: 2093.368.105) meshes directly with mating gears to maintain correct gear ratios and reduce drivetrain noise. Its robust construction minimizes backlash, directly supporting the longevity of adjacent components such as the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING that support shaft alignment.
Symptoms of Failure
- Whining or grinding noise during gear engagement: Worn gear teeth cause irregular contact patterns, producing audible metal-on-metal sounds that intensify under load.
- Transmission oil leaks near the countershaft area: Excessive gear wear can increase internal pressure, forcing lubricant past seals and gaskets.
- Gear slipping or delayed engagement: Damaged spur gear teeth fail to maintain positive mesh, leading to intermittent power loss or hesitation when shifting.
- Metal debris in transmission fluid: Flaking or pitting on the gear surface contaminates the oil, accelerating wear on the 2093209023: DIFFERENTIAL and other rotating assemblies.

Compatibility
This spur gear is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It also fits select variants of the WG180 and WG200 series where the countershaft gear cluster shares identical tooth profiles and spline dimensions. For proper installation, verify the gear’s backlash clearance with the mating 5838300626: DIFFERENTIAL HOUSING to ensure correct alignment.

Frequently Asked Questions
Q: Can the ZF 2093.368.105 spur gear be replaced without removing the entire transmission?
A: In most WG-series transmissions, the countershaft must be extracted to access this gear. Partial disassembly of the differential housing and taper roller bearings is required. We recommend inspecting the 5838300811: THRUST WASHER simultaneously.
Q: What causes premature wear on this spur gear?
A: Common causes include insufficient lubrication, misaligned shafts due to worn taper roller bearings, or contamination from debris generated by a failing differential. Always replace the 0631329088: SPRING PIN when reinstalling.
Q: Is this gear compatible with aftermarket differentials?
A: The 2093.368.105 is designed for OEM ZF differentials. Using non-OEM parts like the 2093209023: DIFFERENTIAL may alter tooth contact patterns and reduce service life.
