Overview
This OEM genuine ZF 0501.211.371 is a critical internal component designed for the WG150, WG160, WG210, and WG65 series transmissions. It functions as a precision-machined spacer or thrust washer within the planetary gear set, ensuring correct axial clearance and load distribution during operation. The SKU 0501.211.371 is manufactured to ZF’s original tolerances, making it essential for maintaining proper gear alignment and preventing premature wear on adjacent assemblies. When rebuilding a transmission, this part is often replaced alongside the 4616105402: OUTPUT and the 4005303005: OUTPUT FLANGE to restore factory clearances.
Symptoms of Failure
- Whining or grinding noise from the transmission housing: When the 0501.211.371 wears beyond specification, metal-on-metal contact occurs inside the gearset, producing a distinct high-pitched whine during acceleration or deceleration.
- Intermittent gear slipping under load: Excessive axial play caused by a worn spacer allows the planetary gears to shift out of alignment, resulting in sudden loss of torque transfer when climbing or hauling heavy loads.
- Metallic debris in transmission fluid: A failing 0501.211.371 sheds fine steel particles into the oil, which can be detected during routine fluid changes or filter inspections.
- Oil seepage near the output flange interface: Worn clearances can distort the sealing surface, leading to slow leaks around the 4616101119: TRANSMISSION HOUSING joint.

Compatibility
This genuine ZF spacer is engineered for the WG 65, WG 150, WG 160, and WG 210 series transmissions. It is also commonly used in the WG 180 and WG 200 models when specified in the original planetary carrier assembly. Always verify the part number against your transmission’s parts manual before ordering. For a complete rebuild, consider inspecting the 0636011038: HEXAGON SCREW that secures the output flange, as thread wear can compromise torque specs.

Frequently Asked Questions
Q: Can I reuse the old 0501.211.371 spacer during a rebuild?
No. ZF recommends always replacing this thrust washer with a new OEM part because it work-hardens and loses its original thickness, which directly affects planetary gear end-play.
Q: Does this part fit the WG 180 transmission?
Yes, the 0501.211.371 is compatible with WG 180 models that share the same planetary carrier design as the WG 160 and WG 210 series. Cross-check your transmission serial number for confirmation.
Q: What torque should I use for the hexagon screws that secure the output flange?
Refer to the ZF service manual for your specific model. Typically, the 0636011038: HEXAGON SCREW requires 85–95 Nm with thread locker applied.
