Gearbox Rebuilding in Fontana
A gearbox rebuild at our Fontana shop is a manufacturing job, not a wash-and-reseal. The box is torn down, every gear, shaft, bearing surface and housing bore is measured and documented, worn components are renewed or manufactured in our own shop, and the rebuilt unit is assembled to specification and tested before it leaves.

What a proper rebuild includes
Complete disassembly and cleaning; inspection of gear teeth for pitting, scoring and fatigue; bearing and seal renewal; shaft repair or manufacture; housing and bore restoration where fretting or spin damage has occurred; correct backlash and bearing preload on assembly; and run testing. The failed parts and the measurements behind every recommendation are photographed — you see what we see.

Frequently asked questions
How long does a gearbox rebuild take?
It depends on the box and what inspection finds — a straightforward bearing-and-seal renewal is days; manufacturing obsolete gears adds machine time. The quote includes the practical timeline.
Can you rebuild a gearbox the manufacturer no longer supports?
Yes — that is one of the most common reasons boxes come to us. We reverse engineer and manufacture the discontinued components.
