How it works
How a Rebuild Works
Back to original specification.
Replace What Wears
A Horton kit replaces the friction linings, bearings, seals and springs, so the drive goes back to its original specification for less than a new one.
Quick Fit: Pre-Assembled
Quick Fit kits come with the front fan mounting assembly, liner and clutch pack already built. They bolt on with eight screws – no left-hand thread, no special Torx Plus bit and no air needed to seat the assembly.
Test It
After every HT/S or DMA repair, an air decay test (ADT150) confirms the seals are seated and the drive holds air.
