ZF 4657.199.003 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.199.003 LOOSE PARTS set is a critical service kit designed specifically for the WG 210 series transmission. This assembly contains the necessary loose components required to rebuild or service the internal clutch and valve body area, ensuring precise hydraulic pressure control and smooth gear engagement. As an OEM genuine part, the SKU 4657.199.003 guarantees exact fitment and material integrity, matching the original factory specifications for ZF’s heavy-duty powershift transmissions. When installed alongside the 4657101033 TRANSMISSION HOUSING, this kit restores the sealing and alignment integrity of the main gear train.

Symptoms of Failure

When the components within the 4657.199.003 LOOSE PARTS kit begin to degrade, operators often notice specific operational issues. One common symptom is erratic gear engagement or delayed shifting, particularly under load, which indicates worn sealing elements or loose fasteners inside the valve body. Another frequent failure mode is low hydraulic pressure accompanied by transmission overheating, as degraded parts fail to maintain proper oil flow channels. You may also experience intermittent oil seepage from the front section where the 4657201027 HOUS.FRONT SECT mates with the main housing. Finally, metallic debris in the transmission oil pan often points to loose or fractured internal hardware from this kit.

Technical Specifications

Compatibility

This LOOSE PARTS kit is engineered primarily for the ZF WG 210 series transmission, but its design allows cross-compatibility with earlier WG 200 and WG 180 models that share the same internal architecture. It is essential to verify that the 4657201012 HOUSING REAR PART and the 0631306792 CYLINDRICAL PIN are in good condition when replacing this kit, as these components work in tandem to maintain concentric alignment. The kit also fits ZF’s off-highway and industrial transmissions used in construction equipment, agricultural tractors, and material handlers requiring a WG-series gearbox.
