: Blower speed sensor

05-21-11, 02:50 PM
I haven't poked around the Eaton yet to see what spare orifices there may or may not be for an external sensor to be added. Heck, I've hardly pulled off the plastic cover yet...

Is there an open port anywhere to install a sensor? Seems pretty easy to put something in the lid; however, probably not the best for picking up shaft speed.

Hey Eric,

FYI, the blower speed is proportional to the engine speed, unless you suspect the belt is slipping.

If you measure the crank and blower pulley diameters, the blower speed is (crank dia/blower dia) * engine RPM.
