AMPCO Pumps SX11000037-ND Front Seal Driver

AMPCO Pumps SX11000037-ND, also listed as 131160 757 Front Seal Driver, is a service tool designed to assist with installation and seating of the 757 front seal on Ampco LF-series pumps. The item is described as Driver, 757, Front Seal, New Design LF, and is explicitly marked as sold separately from the pump assembly, signaling its role as a maintenance accessory rather than a standalone pump component. In Ampco’s 2025 replacement-parts documentation for LF-series components, SX11000037-ND appears in the front-seal category, confirming its compatibility with the New Design LF front-seal configuration used by Ampco LF pumps. This driver supports front-seal maintenance within the LF design, a front-loading seal arrangement that differentiates LF pumps from other Ampco series.
