Overview
The ZF 2095.309.056 GEAR RING is a critical OEM genuine component engineered for the WG100, WG130, and WG131 transmission series. This gear ring functions as the primary torque-transfer interface within the planetary gear set, directly engaging with the 2095109016 DIFFERENTIAL to modulate power distribution from the input shaft to the output carrier. Precision-machined from case-hardened alloy steel, the 2095.309.056 ensures concentric rotation under high-load conditions. When installed alongside the 0750117075 TAPER ROLLER BEARING, it maintains axial stability and reduces frictional heat generation. This SKU is the direct OEM replacement, guaranteeing factory-specified backlash tolerances for WG-series transmissions.
Symptoms of Failure
- Intermittent gear slipping under load: A worn 2095.309.056 gear ring loses tooth profile integrity, causing the 2095209037 DIFFERENTIAL to momentarily disengage during acceleration, particularly in 3rd and 4th gears.
- Metallic grinding noise from the differential housing: As the gear ring’s hardened surface erodes, metal particles contaminate the lubricant, producing a distinct whine or grind that intensifies with RPM.
- Oil leaks near the output flange seal: Excessive radial play from a deformed gear ring stresses the 2095309059 DIFF.HOUSING, distorting the seal seat and allowing ATF to weep past the bearing carrier.
- Delayed engagement when shifting from Park to Drive: A chipped or cracked gear ring prevents the planetary carrier from locking properly, resulting in a 2-3 second hesitation before power transfer resumes.

Compatibility
This gear ring is specifically designed for ZF WG-series powershift transmissions. Verified compatible models include WG100, WG130, and WG131 (all variants). It also fits select WG180 and WG200 units manufactured after 2010, provided the differential housing uses the 2095309059 interface. Always cross-reference the transmission serial number with the 2095.309.056 suffix to confirm fitment. The part directly mates with the 2095109016 DIFFERENTIAL and requires the 0750117075 TAPER ROLLER BEARING for proper preload adjustment.
