Gearbox Repair 

C-B Gear is a complete gearbox repair facility. We do bearing replacements to complete overhauls. We have the capability to manufacture gears when OEM parts are not available. C-B Gear will determine a cost-effective and high quality repair of your gearbox.  

Premature Failures

If your gearbox is failing before the expected life, please let us know so that we can work with you to extend its life.  We will use your information and examine the unit for items such as pitting, overload, misalignment, fatigue, and soft foot.

Upgrade Your Gearing

Recent technology (within the last 10 years) has allowed us to give our customers the full benefit of better gearing. Gear quality is normally increased on older gearboxes through the use of CNC Form grinding. Form grinding improves gear contact by allowing for tooth form modification.
