What are the primary benefits of fitting the GPM STMX1200 gears?

The set offers increased wear resistance and stable tooth engagement compared with softer materials, helping to reduce maintenance frequency and improve drivetrain consistency under repeated load.

Any installation notes for technicians?

During assembly ensure correct mesh and backlash, verify bearing preload and confirm shafts are free of play. Clean mating surfaces and apply appropriate grease to protect gear surfaces.

How should the gears be inspected over time?

Perform regular visual checks of tooth faces for pitting or uneven wear, monitor bearing condition that affects alignment, and replace components at first signs of progressive damage to protect the differential assembly.
