My old Webster YC hydraulic fan motor was 1.94 cu.in./rev. I'm seeing lots of Webster K fan motors on eBay for cheap (WAY less than I paid for my YC that burst apart after 6 miles), but they're all 1.63 cu.in./rev size. However, would a 1.63 motor turn faster than a 1.94 if it's powered by the same pump? Gillig used the Webster 1.63 motors in their Phantom buses to turn fans slightly larger than mine, so I'm thinking that a 1.63 motor should be plenty powerful to turn my fan, and if it turned slightly faster then that's a benefit - more air through the radiator is A Good Thing. My assumption is that a smaller motor will turn faster but produce less torque - am I right?
Who knows if Quality Control Corporation will warranty my burst motor or not? They're still "evaluating" it after having it almost three weeks. If they replace it, great, and if they don't I now have a Plan B that uses any other motor instead, but mounted differently than before.
Thanks, John
