Overview
The ZF 2093.298.135 GEAR is a critical power-transfer component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part sits within the gear train assembly, directly meshing with adjacent shafts to modulate torque and rotational speed during gear shifts. As a hardened steel component, it ensures precise engagement and minimal backlash under heavy industrial loads. The SKU 2093.298.135 is machined to exact ZF tolerances, making it a direct replacement for worn or damaged gears that compromise driveline efficiency. When paired with the 2093101016: HOUSING, this gear maintains proper alignment within the transmission casing, reducing vibration and extending service life.
Symptoms of Failure
- Audible gear whine or grinding noise during acceleration: Worn teeth on the 2093.298.135 gear create uneven contact patterns, producing a high-pitched whine that intensifies under load. This is a common long-tail search query for “ZF transmission whining noise WG100”.
- Intermittent gear slipping under heavy torque: As the gear’s tooth profile degrades, it fails to maintain positive engagement with mating shafts, causing sudden power loss or “slipping” during uphill climbs or loaded starts.
- Metallic debris in transmission fluid: Flaking or pitting on the gear surface releases fine steel particles into the oil. This often triggers filter clogging and is frequently searched as “metal shavings in ZF transmission fluid”.
- Hard shifting or delayed engagement: Excessive wear alters the gear’s helix angle, making synchronizer engagement difficult. Operators may notice a “notchy” feel when moving through the WG130 gear range.

Compatibility
This gear is specifically designed for the ZF WG100, WG130, and WG131 transmission models. It also fits select variants of the WG180 and WG200 series when used in the auxiliary drive position. The gear interfaces directly with the 2093301030: TRANSMISSION HOUSING to ensure correct shaft spacing. For proper identification, always verify the 0730365092: TYPE PLATE on your unit, as it lists the exact model code. The gear is secured using a 0631311009: GROOVED STUD that prevents axial movement during high-RPM operation.

Frequently Asked Questions
Q: Can the 2093.298.135 gear be used in a ZF WG200 transmission?
A: Yes, this gear is compatible with WG200 models that share the same auxiliary drive configuration. However, always cross-reference the tooth count and helix angle with your existing gear to ensure proper mesh.
Q: What tools are needed to replace this gear?
A: Replacement requires a bearing puller, torque wrench, and a press for the interference fit. The 0631311009: GROOVED STUD must be removed and replaced with a new one to maintain clamping force.
Q: How do I confirm this is the correct part for my WG130?
A: Locate the 0730365092: TYPE PLATE on the transmission housing. The model code will include “WG130” followed by a variant number. If the plate is missing, measure the gear’s outside diameter and tooth count to match the specs above.
