Overview
The ZF 2093.349.027 INPUT SHAFT is a critical torque-transfer component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part serves as the primary interface between the engine’s output and the transmission’s gear train, converting rotational force into controlled forward motion. As the first rotating element in the driveline, it must withstand high torsional loads and maintain precise alignment with the 2093109008 DIFFERENTIAL assembly. The SKU 2093.349.027 is manufactured to ZF’s exacting metallurgical standards, ensuring minimal runout and optimal load distribution across the gear mesh.
Symptoms of Failure
- Transmission gear slipping under load: A worn input shaft can cause intermittent disengagement between the clutch pack and planetary gears, leading to power loss during acceleration or hill climbs.
- Oil leaks near the bell housing: When the shaft’s sealing surface becomes scored or pitted, transmission fluid seeps past the front seal, leaving visible drips on the ground.
- Abnormal whining or grinding noises: As the splines wear unevenly, the shaft produces a metallic chatter that intensifies with engine RPM, often mistaken for bearing failure.
- Vibration through the gearshift lever: Excessive shaft play transmits harmonics into the cab, particularly noticeable when coasting in neutral.

Compatibility
This input shaft is designed exclusively for ZF’s WG-series transmissions with a 100–131 torque rating. Verified compatible models include WG100, WG130, and WG131. It also fits select WG180 and WG200 variants when paired with the correct 0750117075 TAPER ROLLER BEARING and 2093209096 DIFFERENTIAL assembly. For installations requiring a new housing, the 2093309073 DIFF.HOUSING provides the necessary structural support. Always verify the transmission serial number before ordering to ensure correct spline count and pilot bearing fitment.

Frequently Asked Questions
Q: Can I install this input shaft without replacing the taper roller bearing?
A: It is strongly recommended to replace the 0750117075 TAPER ROLLER BEARING simultaneously, as worn bearings accelerate shaft wear and cause premature failure.
Q: Does this part fit the WG180 transmission?
A: Yes, the 2093.349.027 is compatible with WG180 models that use the same spline profile, though you should verify the pilot bearing bore diameter against your housing.
Q: What is the typical service life of this input shaft?
A: Under normal operating conditions with proper lubrication, the shaft lasts 8,000–12,000 hours. Frequent heavy loading or contamination can reduce this interval significantly.
