Our Boston Gear Repair Process
- Incoming inspection. We record the model, ratio and mounting, and check for leaks, noise and backlash.
- Teardown. We drain the unit and inspect gears, worm, bearings, seals and housing.
- Failure analysis. Wear patterns tell us whether the cause was lubrication, overload, misalignment or contamination.
- Written quote. You receive a rebuild quote, and a replacement quote when a new Boston Gear unit is the better choice.
- Rebuild. New bearings and seals, gear sets where needed, shaft machining and fresh lubricant.
- Run testing before the unit is returned.
Common Reasons Boston Gear Gear Reducers Come In
- Oil leaks from worn seals
- Worn worm gears and bronze gear sets
- Bearing failure and excessive backlash
- Overheating from overload or low lubricant
- Cracked housings and damaged shafts
What to Send for a Quote
Send a photo of the reducer’s nameplate. On Boston Gear reducers, the catalog number identifies the series, size, ratio and mounting. Include the motor nameplate if one is attached, and how quickly you need the unit back.
Frequently Asked Questions
Is it worth rebuilding a Boston Gear reducer?
Larger reducers and hard-to-get configurations are usually worth rebuilding. Small, common reducers are often cheaper to replace. We will quote both.
Can you repair the motor and gearbox together?
Yes. We repair the motor and the reducer in the same job, so the assembly comes back ready to install. See our gearbox repair page.
