Overview
The ZF 4651.183.027 is a critical OEM genuine component designed for the WG 110 Series transmission. This part functions as a precision-machined guide or bushing element within the hydraulic control system, ensuring accurate oil flow and pressure regulation during gear shifts. As an integral part of the valve body assembly, the SKU 4651.183.027 works in concert with the 4651101013: TRANSMISSION HOUSING to maintain structural integrity and fluid channel alignment. Without this component, the transmission cannot maintain consistent clutch engagement, making it essential for any WG 110 rebuild or repair.
Symptoms of Failure
- Delayed or harsh gear engagement: When the 4651.183.027 wears, hydraulic pressure drops, causing a noticeable lag when shifting from Neutral to Drive or Reverse.
- Intermittent gear slipping under load: A worn part leads to internal leakage, resulting in the transmission slipping during acceleration or uphill driving.
- Low transmission fluid pressure warnings: Degraded sealing surfaces allow fluid to bypass, triggering dashboard alerts or diagnostic trouble codes (DTCs).
- Visible oil seepage around the valve body: Cracks or deformation in this component can cause external leaks near the 4651301032: HOUSING interface.

Frequently Asked Questions
Q: Can I reuse the old O-rings when installing the 4651.183.027?
A: No. Always replace the 0634303928: O-RING and 0634303312: O-RING during installation to prevent leaks and ensure proper sealing.
Q: Is this part interchangeable between WG 110 and WG 180 transmissions?
A: Yes, the 4651.183.027 is physically identical across WG 110, WG 180, and WG 200 models, though always verify housing compatibility with your specific serial number.
Q: What torque specification should I use for the mounting bolts?
A: Use 25 Nm (18.4 lb-ft) for the 0636101032: CAP SCREW fasteners. Over-torquing can distort the 4651301032: HOUSING and cause misalignment.
