Overview
The ZF 4651.152.006 CLUTCH is a critical torque-transfer component engineered specifically for the WG 100 and WG 110 transmission series. This OEM genuine part sits within the planetary gear set assembly, where it engages and disengages power flow between the input shaft and the intermediate housing. The SKU 4651.152.006 is precision-machined to maintain exacting hydraulic pressure tolerances, ensuring smooth gear shifts under heavy-duty industrial loads. When installed alongside the 4651101005: TRANSMISSION HOUSING, this clutch forms the core of the torque management system, directly influencing driveline efficiency and operational longevity.
Symptoms of Failure
- Delayed or harsh gear engagement — A worn 4651.152.006 clutch often causes noticeable hesitation when shifting from neutral to drive, or produces a jarring engagement that worsens as the friction material degrades.
- Transmission fluid overheating — Internal slippage from a failing clutch generates excessive heat, leading to burnt-smelling oil and potential damage to the 0634303928: O-RING seals.
- Intermittent power loss under load — When climbing grades or hauling maximum payloads, a defective clutch may cause the transmission to momentarily lose torque, often accompanied by a high-pitched whine from the gear train.
- Visible clutch material in the oil pan — Metal or friction particles found during routine fluid changes indicate advanced wear of the 4651.152.006 assembly, requiring immediate replacement to avoid contaminating the 4651301010: HOUSING.

Compatibility
This clutch is directly compatible with ZF WG 100 and WG 110 transmissions. It also fits select variants of the WG 180 and WG 200 series when used in conjunction with the 4651301017: HOUSING adapter. The 4651.152.006 is not interchangeable with earlier WG 80 models due to spline count differences. Always verify the clutch pack clearance using the correct shim specifications when installing this part into any WG-series gearbox.
