ZF 4656.301.048 OIL FEED.HOUSG. for WG210 | OEM Genuine Part

Overview

The ZF 4656.301.048 OIL FEED.HOUSG. is a precision-engineered hydraulic component designed for the WG 210 series of heavy-duty transmissions. This genuine OEM part serves as the critical oil feed housing that directs pressurized lubricant from the pump to the clutch packs, planetary gearsets, and torque converter. Positioned within the main transmission casing, it ensures consistent fluid delivery under high-load conditions. The SKU 4656.301.048 is manufactured to exact ZF tolerances, guaranteeing seamless integration with the 4657101042 TRANSMISSION HOUSING and the 4657201028 HOUS.FRONT SECT.

Symptoms of Failure

• Oil leaks at the housing seam: A worn OIL FEED.HOUSG. often causes fluid seepage between the housing and the 4657201013 HOUSING REAR PART, leading to low transmission fluid levels.
• Delayed or harsh gear engagement: When the oil feed housing cracks or distorts, hydraulic pressure drops, resulting in sluggish shifts or clunking during acceleration.
• Overheating transmission: Restricted oil flow through a damaged housing starves internal components of lubrication, causing elevated operating temperatures and potential thermal damage.
• Whining noise from the pump area: A failing housing can introduce air into the hydraulic circuit, producing a high-pitched whine that intensifies under load.

Technical Specifications

Compatibility

This OIL FEED.HOUSG. is specifically engineered for the ZF WG 210 series, but it also fits select models in the WG180, WG200, and WG250 families when used with the correct 0631306792 CYLINDRICAL PIN for alignment. It is not backward-compatible with older WG120 or WG150 units without significant modification. Always verify your transmission’s serial number against the ZF parts catalog before ordering.
