ZF 4657.199.017 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.199.017 LOOSE PARTS kit is a critical service assembly designed for the WG 210 Series transmission. This genuine OEM part set contains the essential fasteners, seals, and positioning components required to secure internal sub-assemblies during a rebuild or major repair. Specifically, this kit interfaces directly with the main casing structure, ensuring that the TRANSMISSION HOUSING and the HOUS.FRONT SECT maintain precise alignment under high torque loads. The SKU 4657.199.017 is the definitive reference for this loose parts bundle, which is often overlooked during routine maintenance but is vital for preventing oil migration between chambers.

Symptoms of Failure

When the components within the 4657.199.017 kit degrade or are improperly torqued, specific operational issues arise. Look for these failure indicators:

• External oil seepage at the housing joint: Worn gaskets or loose fasteners from this kit cause fluid to weep where the HOUSING REAR PART meets the main body.
• Intermittent gear engagement hesitation: A loose CYLINDRICAL PIN within this set can allow the shift rail to drift, causing delayed or missed shifts under load.
• Abnormal vibration from the bell housing area: Missing or damaged loose parts can lead to micro-movement of the front section, creating a low-frequency rumble during acceleration.
• Contaminated transmission fluid: Failure of the sealing elements in this kit permits dirt ingress through the housing interface, accelerating wear on internal clutches.

Frequently Asked Questions

Q: Can I reuse the old fasteners from the 4657.199.017 kit?
A: No. ZF specifies that all bolts and pins in this loose parts kit are single-use due to stretch and thread deformation. Always install the new components from the kit to maintain clamp load integrity.

Q: Does this kit include the gasket for the HOUSING REAR PART?
A: Yes. The 4657.199.017 set contains the sealing ring and the CYLINDRICAL PIN required to align the rear housing. However, the main housing gasket is sold separately under part number 4657101033.

Q: How do I verify if this kit fits my WG 210 transmission?
A: Check the serial number plate on the HOUS.FRONT SECT. If the casting number ends in “210”, this kit is the correct match. For WG 200 units, measure the bolt spacing to confirm compatibility.
