ZF 4657.354.068 INPUT GEAR for WG210 | OEM Genuine Part

Genuine ZF INPUT GEAR (Part No. 4657.354.068). This part fits: 5 WG 210. Found in: Power Take Off. Also referenced as: 4657354068 / 4657.354.068 / 4657 354 068.

Overview

The ZF 4657.354.068 INPUT GEAR is a critical OEM genuine component engineered specifically for the WG210 series transmission. This precision-machined gear serves as the primary torque input interface, transferring rotational force from the engine directly into the transmission’s planetary gearset. Positioned at the front of the main shaft assembly, the 4657.354.068 input gear meshes seamlessly with the clutch pack and the TRANSMISSION HOUSING to ensure smooth power delivery. As an OEM genuine part, SKU 4657.354.068 guarantees exact fitment and metallurgical integrity, reducing the risk of premature wear in heavy-duty industrial applications.

Symptoms of Failure

  • Transmission gear slipping under load: A worn input gear loses tooth engagement, causing intermittent power loss during acceleration or uphill operation.
  • Whining or grinding noise from the bell housing: Damaged gear teeth produce a high-pitched whine or metallic grinding, especially noticeable at low RPMs.
  • Metal debris in transmission fluid: Flaking or chipped gear material contaminates the oil, often visible during routine drain intervals.
  • Hard shifting or delayed engagement: Excessive backlash from a degraded input gear disrupts synchronization, leading to clunky gear changes.
