ZF 4660.152.004 REVERSING GEAR for WG200/WG92 | OEM Genuine Part

Overview

The ZF 4660.152.004 REVERSING GEAR is a critical component engineered for the WG200 and WG92 series transmissions. This OEM genuine part facilitates the directional shift mechanism, allowing the operator to seamlessly transition between forward and reverse motion under load. Positioned within the lower planetary gearset assembly, the reversing gear directly engages with the output shaft to manage torque flow. The SKU 4660.152.004 is precision-machined to ZF’s original tolerances, ensuring exact fitment and long service life. When paired with a properly maintained 4660198001 PERIPHERALS kit, this gear maintains consistent hydraulic pressure for reliable shifting.

Symptoms of Failure

• Delayed or harsh reverse engagement: A worn 4660.152.004 gear often causes a noticeable lag when shifting into reverse, accompanied by a clunking noise. This is a common long-tail search query for “ZF WG200 reverse engagement delay.”
• Oil leaks near the shift housing: Degraded gear teeth or bearing surfaces can increase internal pressure, forcing transmission fluid past seals. Look for drips around the 0501209818 RANGE SELECTOR assembly.
• Grinding or whining in reverse only: If the gear surface becomes pitted or chipped, a distinct metallic grinding sound will occur exclusively during reverse operation. This symptom often leads to searches for “ZF WG92 reverse gear noise.”
• Intermittent loss of reverse drive: As the gear wears, it may slip out of engagement entirely, leaving the vehicle unable to reverse. This is frequently misdiagnosed as a 4660101011 TRANSMISSION HOUSING crack, but the reversing gear is the primary culprit.

Technical Specifications

Compatibility

This reversing gear is designed for ZF’s WG series powershift transmissions. It is a direct fit for the WG200 and WG92 series, commonly used in industrial forklifts, reach stackers, and heavy-duty material handlers. The part also retrofits into earlier WG180 and WG120 models when paired with the correct 4660301018 HOUSING adapter. Always verify your transmission serial number before ordering, as minor spline variations exist across production years.
