Overview
The ZF 4646.302.147 CONVERTER BELL is a critical structural component engineered specifically for the WG 260 Series transmission family. This OEM genuine part, identified by SKU 4646.302.147, serves as the rigid housing that connects the torque converter assembly to the main transmission casing. It precisely aligns the converter with the pump and turbine, ensuring efficient power transfer from the engine to the drivetrain. Without this bell housing, the converter would lack the necessary support and alignment, leading to severe operational instability. The 4646.302.147 is machined to exacting tolerances to withstand high torsional loads and thermal expansion, making it indispensable for heavy-duty industrial applications.
Symptoms of Failure
When the ZF 4646.302.147 converter bell begins to fail, operators often notice oil leaks around the bell housing joint, which can be traced to warping or cracking of the casting. Another common symptom is gear slipping under load, caused by misalignment of the torque converter relative to the input shaft. You may also experience vibration during acceleration, as a worn bell housing fails to dampen rotational forces. In advanced cases, difficulty engaging gears occurs due to the converter shifting out of its proper axial position. Addressing these issues promptly with a genuine replacement prevents cascading damage to the TRANSMISSION HOUSING and other internal components.

Compatibility
This converter bell is primarily designed for the WG 260 Series transmission, but it also fits select models in the WG180, WG200, and WG240 families due to shared bolt patterns and converter dimensions. It is a direct replacement for units requiring the 4646.302.147 casting. For proper installation, always pair this bell with the HOUSING and secure it using 螺栓 or CAP SCREW fasteners. Verify your transmission model number before ordering to ensure a perfect fit.
