Pump To Drum Bearing

The Coan Racing COA‑32430 Pump‑to‑Drum Bearing is a precision-engineered component designed to support the interface between the transmission pump and drum in Turbo Hydramatic 350 transmissions. Manufactured to Coan’s exacting standards, this bearing ensures smooth, low-friction rotation at a critical junction, helping to prevent premature wear and maintain proper alignment under high RPM and pressure loads. As indicated in Coan’s transmission component catalog, it is required for installations featuring lightened input ring gears and other high-performance modifications to reinforce structural integrity and hydraulic efficiency. This bearing is essential for both competition and performance street builds, offering durability and reliable support in demanding transmission environments.
