Flender Gearbox Repair in Fontana
Flender drives — built under Flender, Siemens and Winergy badges over the years — power some of the heaviest lines in the region. When one needs more than a seal kit, our Fontana shop does the full job in-house: teardown, inspection, rebuild, and manufacture of replacement gears for Flender units the factory no longer supports.

Helical, bevel-helical and planetary Flender drives
We rebuild Flender helical and bevel-helical gear units, planetary stages and the shafts, bearings and gearing inside them. Every unit is measured before it is quoted, so the repair scope is based on the actual wear in your drive — not a guess over the phone. Gears worn beyond limits are re-cut or manufactured new in the same building, matched to the housing and the duty the drive sees.

Factory support ends. Ours doesn't.
Badges and ownership around the Flender lines have changed repeatedly, and support for older units can be slow or simply unavailable. A local rebuild bench with its own gear manufacturing closes that gap: your drive is assessed on its condition, not its catalog status. Regular hours Monday–Friday 6 AM–5 PM; rush and emergency repair runs 24 hours a day, 365 days a year, with free quotes and free pick-up and delivery.

Frequently asked questions
Can you get parts for an older Flender gearbox?
Where factory parts are unavailable or too slow, we manufacture the gearing and shafts ourselves from the original parts — that is the core of our gear shop.
How fast can a Flender rebuild turn around?
It depends on the damage found at teardown. Rush work is what our 24-hour line exists for — call (800) 821-3404 and we will give you a straight answer on timing.
