MAIN BEARING PRODUCTION:   This project started when our local John Deere dealer came to us after having bearing seizure problems caused by O.E. bearings made of Bronze material. We now make these bearings from aluminum cast material and have the patterns made, castings poured and the fixtures for machining them. Bearings are ready to install and bored to finish size. They can also be machined for a smaller undersize than the J.D. bearing or with an oversize O.D. to repair damaged housings.  Our bearings have been in service for years with excellent results.  Call or e-mail us with any questions you may have about our John Deere main bearings at info@motormachining.com.
