Selling the pony motor off my 1954 D69U. I pulled the motor off when restoring the dozer. Pony is complete, but locked up. It was easier for me to just to convert to 24 volt starter than mess with rebuilding it. Pistons seem to move, but valves are rusted solid. Located in NC, about an hour southwest of Raleigh. Make a reasonable offer... 919-930-9200
