Sorry, but I am actually very disappointed in the motor I received. it is simply the wrong part. I should have known when the installation had to be modified. The hold-down bolts where threaded on the original and thru-bolted and had nuts on the replacement. However, everything else looked good and I know small product changed take place during the assembly sometimes, so I went forth with the installation. However, when complete, the motor shaft was orientated too high in the mounting and the blade could not turn.
