ATC 40127 Eaton UltraShift Plus Input Shaft Bearing Puller – Shaft #4308011

The ATC 40127 Eaton Input Shaft Bearing Puller is a purpose-built heavy-duty service tool engineered specifically for Eaton Fuller UltraShift Plus automated manual transmissions utilizing input shaft #4308011. This specialty puller is designed to safely and efficiently remove the input shaft bearing without damaging the shaft, bearing race, or surrounding transmission components—critical when servicing high-value UltraShift Plus units.

Manufactured from high-strength, heat-treated steel, the ATC 40127 provides the rigidity and pulling force required to extract tightly seated bearings commonly encountered during transmission overhauls. Its precision-machined gripping surfaces securely engage the bearing, ensuring straight, controlled removal while minimizing the risk of slippage or shaft scoring.

Unlike generic bearing pullers, this tool is application-specific, allowing technicians to service UltraShift Plus transmissions without disassembling additional geartrain components. This saves labor time and reduces the potential for collateral damage. The compact, balanced design makes it ideal for both in-shop rebuilds and fleet maintenance environments where efficiency and repeatability are essential.

The ATC 40127 is widely used by transmission rebuilders, dealership service departments, and independent heavy-duty repair shops working on Eaton automated manual transmission systems.
