Cranky,
Yes, I'm an engineer with 40+ years experience in industry (Maintenance Manager position with 70 trades people working for me in a chemicial plant with ALL equipment involved) with my responsibility for keeping all plant processes and equipment safe, operational and productive, I've come to realize that NOT to cut material costs for the purpose unsubstantiated gains.
Selecting the "right" relacment part for a failed compnent is paramont to a successful recovery and long term profitable operation.
My experiences were with 100 ton overhead cranes, coal fired steam boilers, process pumps, mobil machinery (outdoor crawler cranes, 84 ton diesel locomotives, fork trucks), high temp furnaces, plant electrical power distribution equipment, etc. I believe that these items qualifies me to have and make my directed opinions.
Regarding the "Green Bearings", what is their published L-10 life expectancy based on normal operating conditions? ....maximum operating conditions?
You state Ford uses ball bearings in their axle designs...where, what positions, what type of bearing ? The Ford 9" rear uses a single row ball bearing at the end of the the pinion gear to control the separating forces at the ring gear pinion gear interface. What are the carrier bearing's? What are the pinion bearings? What are the Axle bearings?
