Overview
The ZF 2093.304.112 GEAR is a precision-engineered helical gear designed for the auxiliary drive and power take-off (PTO) circuits within the WG100, WG130, and WG131 transmission series. This OEM genuine part, identified by SKU 2093.304.112, sits directly on the intermediate shaft cluster, transferring torque from the input shaft to the differential assembly. Its hardened tooth profile ensures quiet operation and minimal backlash under heavy load. When paired with a matching DIFFERENTIAL, this gear maintains consistent oil flow and gear mesh alignment, preventing premature wear on adjacent bearings.
Symptoms of Failure
- Whining or howling noise during deceleration: Worn teeth on the 2093.304.112 gear create a distinct high-pitched whine that intensifies as the transmission cools, often misdiagnosed as a failing TAPER ROLLER BEARING.
- Intermittent gear slipping under load: Chipped or spalled gear faces cause the drive to momentarily lose engagement, particularly when climbing grades or reversing.
- Metallic debris in transmission oil filter: Fine silver or steel particles indicate the gear’s case-hardened layer has worn through, accelerating damage to the DIFFERENTIAL and DIFF.HOUSING.
- Oil leakage from the PTO cover gasket: Excessive gear vibration loosens the housing bolts, allowing fluid to weep past the seal.

Compatibility
This gear is factory-specified for the ZF WG100, WG130, and WG131 powershift transmissions used in agricultural tractors and construction loaders. It also fits select variants of the WG180 and WG200 series when used with the correct SPRING PIN and THRUST WASHER kit. Always verify the gear’s spline count and shaft diameter against your transmission’s service manual before installation.

Frequently Asked Questions
Q: Can I replace the 2093.304.112 gear without removing the entire transmission?
A: Yes, on most WG100/WG130 models the gear is accessible after removing the PTO cover and intermediate shaft retaining ring. However, you must also inspect the TAPER ROLLER BEARING for brinelling before reassembly.
Q: How do I identify a counterfeit ZF 2093.304.112 gear?
A: Genuine ZF gears have a laser-etched part number on the hub face and a distinct case-hardened blue-black finish. Counterfeits often show rough machining marks and weigh 5-10% less than the specified 1.85 kg.
Q: Is the 2093.304.112 gear compatible with the WG180 transmission?
A: It is compatible only if your WG180 uses the 32-tooth intermediate shaft cluster. Check your parts manual for the spline count; if it differs, you will need the DIFFERENTIAL AXLE adapter kit.
