ZF 4642.302.134 OUTPUT SHAFT for WG150 | OEM Genuine Part

Overview

The ZF 4642.302.134 OUTPUT SHAFT is a critical driveline component engineered specifically for the WG 150 series of heavy-duty transmissions. This OEM genuine part transmits rotational torque from the planetary gear set to the vehicle’s drive shaft, ensuring smooth power delivery under extreme loads. As a precision-machined shaft, it interfaces directly with the TRANSMISSION HOUSING (4642101109) and the TRANSMISSION HOUSING (4642301205) to maintain concentric alignment. The SKU 4642.302.134 is factory-balanced to minimize vibration and extends service life in municipal buses, construction equipment, and marine applications.

Symptoms of Failure

• Output shaft oil leaks at the rear seal area – Worn splines or bearing journals allow lubricant to escape, leaving puddles under the transmission bell housing.
• Gear slipping or delayed engagement under load – A fatigued shaft can cause misalignment between the planetary carrier and output flange, leading to intermittent power loss.
• Excessive driveline vibration during acceleration – Bent or worn output shafts create harmonic imbalances that resonate through the chassis at 30–50 mph.
• Metallic grinding noise from the rear of the transmission – Damaged splines or bearing surfaces produce a distinct chatter when shifting between forward and reverse gears.

Technical Specifications

Compatibility

This output shaft is primarily designed for the ZF WG 150 series, but it also fits select variants of the WG 180 and WG 200 transmissions when used with the correct TYPE PLATE (0730365125) for model verification. It is compatible with all WG 150 sub-models (WG150-1, WG150-2, WG150-3) produced after 2008. For installations requiring additional retention, pair this shaft with the GROOVED STUD (0631311009) to secure the output flange. Always cross-reference your transmission serial number against the type plate before ordering.
