Leaf-Eater Motor Assy,for LE900

I received the motor, it looks brand new but there are no installation instructions. And while it might be simple to figure out, I'm stuck on removing the flange that the spinner head attaches to...I don't want to break anything by applying too much force and need to know if it is a press fit or a screw-on. And what's the best type of puller to use if that's what is needed. Some simple online instructions would go a long way.

No instructions which didn't help matters. However took my time and figured it all out and replacement went well. Tested unit and all worked great. It's good that Flowtron provides replacement parts for its equipment. Again though some instructions would have been useful. But all's well that ends well .... my Flowtron is back in service! :-)

nice an clean and installed
