ZF 4657.199.060 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.199.060 LOOSE PARTS set is a critical service kit designed specifically for the WG 210 series transmission. This assembly contains the essential fasteners, seals, and positioning components required to secure and align the main housing sections during a rebuild or overhaul. As an OEM genuine part, SKU 4657.199.060 ensures that the structural integrity of the gearbox is maintained, preventing internal misalignment that can lead to premature wear. This kit sits directly between the main casing and the front/rear housing sections, acting as the final locking mechanism for the transmission’s core assembly.

Symptoms of Failure

When the components within the ZF 4657.199.060 LOOSE PARTS kit begin to fail or are not replaced during service, operators often notice specific performance issues. Transmission oil seepage around the mating flanges of the housing is a primary indicator, as degraded fasteners lose clamping force. Another common symptom is abnormal gear engagement noise or a “clunking” sound during shifting, caused by slight housing movement. You may also experience intermittent loss of hydraulic pressure due to misalignment of the valve body passages. Finally, vibration at highway speeds can occur if the rear housing section becomes loose, compromising the output shaft alignment.

Technical Specifications

Compatibility

This LOOSE PARTS kit is engineered for the ZF WG 210 series transmission. While primarily designed for the WG210, the fastening geometry and seal dimensions are shared with the WG180 and WG200 series in certain production years. It is also compatible with the WG211 and WG212 variants that utilize the same housing bolt pattern. Always verify the housing casting numbers before installation. This kit is frequently used in conjunction with the TRANSMISSION HOUSING, the HOUS.FRONT SECT, and the HOUSING REAR PART to complete a full structural rebuild.

Related Components

For a complete overhaul, we recommend pairing the 4657.199.060 kit with the following genuine ZF parts. These components work together to restore the transmission’s structural integrity and sealing performance.

Frequently Asked Questions

Q: Can I reuse the old bolts from my ZF WG210 instead of buying the 4657.199.060 kit?
A: No. ZF specifies that all fasteners in the LOOSE PARTS kit are torque-to-yield and must be replaced. Reusing them can lead to uneven clamping force and eventual oil leaks around the HOUS.FRONT SECT interface.

Q: Does this kit include the alignment pins for the rear housing?
A: Yes. The 4657.199.060 set includes the CYLINDRICAL PIN (0631306816) necessary to align the HOUSING REAR PART correctly during assembly.

Q: How do I know if my WG210 uses the 4657201103 or the 4472239184 rear housing?
A: Check the casting number on the rear bell housing. The 4472239184 variant is typically found on later-model transmissions with a reinforced output flange. Both housings are compatible with this LOOSE PARTS kit.
