Overview
This OEM genuine ZF 4657.130.114 ENGINE CONNECTION is a critical interface component designed for the WG191 and WG211 transmission series. It serves as the primary link between the engine flywheel housing and the transmission bell housing, ensuring precise alignment and secure torque transfer during operation. The part number 4657.130.114 is engineered to ZF’s exacting tolerances, reducing vibration and preventing misalignment that can lead to premature wear on adjacent assemblies. It is frequently replaced alongside the TRANSMISSION HOUSING and the HOUS.FRONT SECT during major overhauls.
Symptoms of Failure
When the engine connection wears or cracks, operators may notice these specific failure indicators:
- Oil leaks at the bell housing joint: A degraded seal surface on the 4657.130.114 can allow transmission fluid to weep past the mating flange, often mistaken for a rear main seal failure.
- Abnormal gear engagement noise: Worn mounting points cause the transmission to shift slightly under load, producing a metallic clunking sound during acceleration or deceleration.
- Increased driveline vibration: Loss of concentricity between the engine and transmission leads to harmonic vibrations felt through the chassis at highway speeds.
- Difficulty in transmission removal or installation: A warped or cracked engine connection can bind against the HOUSING REAR PART, making service procedures significantly more labor-intensive.

Compatibility
This genuine ZF engine connection is specifically engineered for the WG 191 Series and WG 211 Series transmissions. It is also compatible with earlier WG180 and WG200 variants that share the same bell housing bolt pattern. For proper installation, always verify that the CYLINDRICAL PIN is correctly aligned to prevent rotational misalignment. The part is not backward-compatible with WG120 or WG150 series without adapter kits.

Frequently Asked Questions
Q: Can I reuse the old engine connection if it looks clean?
No. ZF recommends always replacing the 4657.130.114 when the transmission is removed, as microscopic stress fractures can develop from thermal cycling. A new part ensures proper sealing against the TRANSMISSION HOUSING.
Q: Does this part come with mounting hardware?
This listing is for the engine connection casting only. You will need to order the CAP SCREW (0636102489) and CYLINDRICAL PIN (0631306816) separately for a complete installation.
Q: How do I verify this fits my WG211 transmission?
Check the casting number on your existing part. If it reads 4657.130.114, it is a direct replacement. For WG191 units, also confirm the HOUS.FRONT SECT part number to ensure bolt pattern compatibility.
