I have a Federal Signal STH10 and require a new motor. I am looking for the motor shaft dimensions, diameter and length.
We recently had the motor rebuilt on this siren and on the first run of the motor it tripped on overload. We discovered the siren requires a 10 HP motor (by amp draw) and we only have a 7.5 HP motor installed. As this siren is in service, I would prefer to not to pull the siren down and rip it apart again to get these dimensions.
Cheers
