AMT 1509-000-09 Shaft and Bearing Assembly in 1070 Steel

AMT 1509-000-09 Shaft and Bearing Assembly

The AMT 1509-000-09 is the genuine replacement shaft and bearing assembly, supplied as a finished unit machined from 1070 steel. It arrives as a matched set — shaft and bearings already pressed and aligned to the factory fit — which is the whole point of buying it as an assembly rather than chasing individual bearings. Getting bearing preload and shaft runout right on the bench is fiddly work; AMT does it for you, so the rotating assembly drops straight into the pump.

This is the part that carries the impeller and transfers torque from the motor, and it is also the part that tells you when a pump is in trouble. Rumbling or grinding from the bearing housing, a shaft that feels notchy when you turn it by hand, visible end play, heat at the housing, or a mechanical seal that keeps failing prematurely all point the same direction. A worn shaft and bearing set lets the impeller wobble, which wrecks seals, opens up running clearances and eventually chews the housing itself — so replacing the assembly early is far cheaper than waiting.

1070 is a high-carbon steel chosen for strength and wear resistance at the bearing journals. When you fit this assembly, replace the mechanical seal at the same time and inspect the bearing housing bore: a housing that has been spun by a failed bearing will not hold the new one either. AMT builds several shaft and bearing assemblies that look similar but differ in shaft length, thread and keyway, so check the part number in your pump’s parts breakdown before ordering.

Key Features

• Genuine AMT (Gorman-Rupp) service part — built to the original drawing
• Supplied as a finished, pre-assembled unit — no pressing or setting up bearings on the bench
• 1070 high-carbon steel shaft for strength and wear resistance at the bearing journals
• Restores factory shaft runout, bearing preload and impeller clearance in one part
• Direct replacement — no machining or modification required

Applications

• AMT pump rebuild work where the shaft or bearings are worn, notchy or noisy
• Repairing a pump that is running hot at the bearing housing
• Correcting repeat mechanical seal failures caused by shaft wobble or end play
• Restoring impeller running clearance after bearing wear
• Marine, dockside, washdown, dewatering and general water transfer service
