ZF 4657.130.403 ENGINE CONNECTION for WG210 | OEM Genuine Part

Genuine ZF ENGINE CONNECTION (Part No. 4657.130.403). This part fits: 6 WG 210. Found in: Engine Connection. Also referenced as: 4657130403 / 4657.130.403 / 4657 130 403.

Overview

The ZF 4657.130.403 ENGINE CONNECTION is a critical OEM genuine interface component designed specifically for the WG 210 Series transmission. This precision-engineered part serves as the primary mechanical link between the transmission assembly and the engine flywheel housing, ensuring accurate alignment and secure power transfer. As an original ZF part, SKU 4657.130.403 guarantees exact fitment and durability under high-torque industrial applications. It sits at the input section of the transmission, directly interfacing with the TRANSMISSION HOUSING to maintain structural integrity and prevent misalignment during operation.

Symptoms of Failure

  • Oil leakage at the engine-transmission interface: A worn ENGINE CONNECTION often causes hydraulic fluid seepage, leading to low transmission fluid levels and potential overheating.
  • Vibration during gear engagement: Degraded mating surfaces result in excessive play, producing noticeable shuddering or shaking when shifting between forward and reverse.
  • Delayed or harsh shifting: Misalignment from a failing part disrupts hydraulic pressure, causing erratic clutch engagement and sluggish response times.
  • Metallic grinding noises: Advanced wear allows metal-on-metal contact between the engine connection and adjacent components like the HOUS.FRONT SECT, indicating imminent failure.
