Subscribe to our blog. # How NOT To Rebuild a Gear Drive Posted by [Marc Bekolay](https://www.bhmachine.com/blog/author/marc-bekolay) on Wed, Oct 21, 2020 @ 12:56 PM - [Tweet](https://twitter.com/share) We recently had a customer say he could get a rebuilt Dodge shaft mount for cheaper than we had quoted him.  After some further discussion, the customer gave us the link to the reducer he was considering. ![s-l1600 (6)](https://www.bhmachine.com/hs-fs/hubfs/s-l1600%20(6).jpg?width=182&name=s-l1600%20(6).jpg)![s-l1600](https://www.bhmachine.com/hs-fs/hubfs/s-l1600.jpg?width=181&name=s-l1600.jpg)![s-l1600 (1)](https://www.bhmachine.com/hs-fs/hubfs/s-l1600%20(1).jpg?width=180&name=s-l1600%20(1).jpg) This rebuilder thinks throwing a fresh coat of paint and maybe changing the seals qualifies as a rebuilt gear reducer.  - They ground the input shaft with a hand grinder and it is clearly no longer round.  - The cavity of the reducer has rust on all surfaces including the bearings.  - The bearings are frosted.  - The bore of the output hub is rusty. - Did they remove all the cups and check the housing for wear? - If no bearings were removed or replaced.  What is the integrity of the bearing areas on the shafts? - We checked availability of the Timken bearings on this unit and a pair of them were 6-week lead time.   To see how gear drive repairs should look [check out this story](https://www.bhmachine.com/blog/industrial-gearbox-repair) of how we took a severely damaged shaft mount Dodge gear reducer type TA3203 Check out our [gear drive and repair page](https://www.bhmachine.com/gear-drive-repair) to see how we would rebuild a gear drive.
