Overview
This ZF 4651.351.067 is a critical OEM genuine component specifically engineered for the WG 110 Series transmission. It functions as a precision-machined internal guide or spacer element, ensuring correct alignment of the planetary gearset and clutch pack assemblies within the transmission housing. The SKU 4651.351.067 is manufactured to ZF’s exacting tolerances to maintain proper hydraulic pressure distribution and mechanical load support. When installed alongside the 4651101013: TRANSMISSION HOUSING, this part forms a sealed, stable environment for the rotating components, directly influencing shift quality and overall drivetrain reliability.
Symptoms of Failure
When the ZF 4651.351.067 wears out or becomes damaged, operators may notice specific performance issues. Look for these common failure indicators:
- Intermittent gear slipping under load – A worn part can cause misalignment, leading to clutch pack slippage during acceleration.
- Low hydraulic pressure warnings – Internal leakage past the component reduces system pressure, triggering fault codes.
- Metallic debris in transmission fluid – Friction from a failing 4651.351.067 generates fine metal particles visible during oil changes.
- Hard or delayed shifting – Misalignment forces the valve body to compensate, resulting in harsh engagement between gears.

Compatibility
This OEM genuine part is primarily designed for the ZF WG 110 Series transmission. It is also compatible with select variants in the WG 180 and WG 200 series that share the same internal architecture. The 4651.351.067 interfaces directly with the 4651301032: HOUSING and the 4651301033: HOUSING to create a sealed chamber. For proper installation, always replace the 0634303928: O-RING to prevent fluid bypass. Verify your transmission model code against ZF’s technical documentation before ordering.

Frequently Asked Questions
Q: Can I install the 4651.351.067 without replacing the O-rings?
A: It is strongly recommended to replace all sealing elements, especially the 0634303928: O-RING, during service. Old O-rings may cause immediate fluid leaks and pressure loss.
Q: How do I know if this part fits my WG 110 transmission?
A: Check the transmission serial number plate. The 4651.351.067 is used in WG 110 models built after 2015. For earlier units, verify compatibility with your local ZF distributor.
Q: What tools are needed for replacement?
A: You will need a torque wrench, snap ring pliers, and a soft-faced mallet. Always consult the ZF service manual for proper torque specifications on the 0636101032: CAP SCREW.
