Overview
The ZF 4657.130.067 ENGINE CONNECTION is a critical OEM genuine component designed specifically for the WG 210 Series transmission. This part serves as the primary interface between the transmission assembly and the engine bellhousing, ensuring precise alignment and secure torque transfer during operation. As a structural link, it absorbs vibrational loads while maintaining a sealed connection to prevent fluid contamination. The SKU 4657.130.067 is machined to exact ZF tolerances, making it a direct replacement for worn or damaged units in heavy-duty industrial applications. When installed alongside the 4657101051: TRANSMISSION HOUSING and 4657201151: HOUS.FRONT SECT, this engine connection restores factory-spec integrity to the drivetrain.
Symptoms of Failure
When the ZF 4657.130.067 ENGINE CONNECTION begins to fail, operators typically notice three to four distinct warning signs. First, oil seepage at the engine-transmission mating surface occurs as the gasket seat degrades, often visible as dark streaks on the bellhousing. Second, intermittent gear engagement hesitation arises from misalignment, causing the transmission to struggle when shifting under load. Third, abnormal driveline vibration at cruising speeds indicates the connection has loosened, allowing rotational play. Fourth, metallic debris in the transmission fluid may appear if the connection fractures, contaminating the oil system. Addressing these symptoms early prevents cascading damage to the 4657201103: HOUSING REAR PART and other internal components.

Frequently Asked Questions
Q: Can the 4657.130.067 be reused after removal?
A: ZF recommends replacing this engine connection with a new OEM part whenever the transmission is separated from the engine, as the sealing surface may deform during disassembly.
Q: What torque specification should I use for installation?
A: Tighten the six M12 bolts to 85 Nm (63 ft-lbs) in a star pattern, then apply a final 90-degree angle turn. Always consult your service manual for exact values.
Q: Does this part include the gasket?
A: No, the 4657.130.067 is sold as a bare component. You must order the corresponding gasket separately from the ZF seal kit for your WG210 model.
