What a proper rebuild includes
Gearboxes are opened and measured gear by gear in this shop — bearings, seals, shafts and housings renewed or restored, gearing re-cut where the wear demands it, and discontinued parts manufactured on our own machines. The rebuild is quoted from the measurements, not from a guess, and the finished drive is checked before it leaves Fontana.

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.
