I got this motor off ebay and thought it was the same size as what I have in my 2-6-8-0 (see photos ) ,but it is smaller. It has the same brush mount as the Mantua stock motor, but is 7 poles compare to the stock 5 pole motor. Can any one give me some specs on the new motor? I have a flywheel that I think could work. The engine runs good, but I would like to improve the crawl. My Mantua 2-6-6-2 with the newer stock can motor with flywheel has worse crawl then this older open frame motor.
