Jet Equipment JT9-32A5721A Replacement Gear Set Metal Lathe

Product Description

The JET EQUIPMENT JT9-32A5721A is a replacement gear set designed for metal working lathes. This set includes gears in 2.25M, 3.25M, and 2.5M 18-tooth configurations, providing the correct tooth profiles and module sizing required for precise feed and threading operations. It is a direct OEM-style replacement component sold individually and intended for installation by qualified machine tool technicians or experienced metalworking professionals performing scheduled maintenance or drivetrain repairs on compatible JET lathes.

This gear set is intended for use with the JET BDB-1340A and JET GHB-1340A metal working lathes. These are bench-style engine lathes commonly found in small manufacturing shops, toolrooms, and vocational training facilities. The gears support the change-gear drivetrain that governs lead screw and feed rod engagement, making them critical components for threading and turning accuracy. Replacement is typically performed when visible wear, chipping, or excessive backlash is detected during routine inspection.

Installation Notes

Installation should be performed by a qualified machine tool technician. Power off and lock out the lathe at the main disconnect before accessing the change-gear guard or gearbox cover. Verify gear module and tooth count match the position being replaced before assembly. Do not force mesh engagement; confirm proper gear center distance and backlash by hand rotation before returning the machine to service.
