ZF 4616.319.010 SPUR GEAR for WG65 | OEM Genuine Part

Overview

The ZF 4616.319.010 SPUR GEAR is a critical power transmission component engineered specifically for the WG 65 series. This OEM genuine part sits within the intermediate shaft assembly of the transmission, where it engages with mating gears to transfer torque from the input shaft to the output shaft. The spur gear’s precision-cut teeth ensure smooth, low-noise operation under heavy loads. The part number 4616.319.010 is a direct OEM replacement, guaranteeing exact fitment and material integrity. During installation, this gear is mounted inside the 4616101059: TRANSMISSION HOUSING, which provides the structural support and alignment necessary for long service life.

Symptoms of Failure

• Whining or grinding noise during gear engagement – Worn spur gear teeth produce a distinct metallic whine, especially under acceleration or deceleration, indicating surface fatigue or pitting.
• Intermittent gear slipping under load – As the gear profile wears, it can lose proper meshing with the mating gear, causing momentary loss of torque transfer and erratic vehicle movement.
• Metallic debris in transmission oil – Flakes or chips of hardened steel found during oil changes signal advanced gear wear, often accompanied by reduced hydraulic pressure.
• Increased operating temperature – Friction from a damaged spur gear generates excess heat, which may trigger thermal warnings or degrade nearby seals like the 0634313118: O-RING.

Technical Specifications

Compatibility

This spur gear is primarily designed for the ZF WG 65 series, but it also fits select variants of the WG180 and WG200 transmissions that share the same intermediate shaft geometry. It is commonly used in heavy-duty commercial vehicles, construction equipment, and marine propulsion systems where the WG65 gearbox is specified. For proper assembly, the gear must be secured using 0636011038: HEXAGON SCREW and 0636011118: HEXAGON SCREW for the bearing retainers, while the 0636016015: HEXAGON SCREW fastens the gear hub to the shaft. Always verify your transmission model number before ordering.
