Thanx Hotratz!... I just bought a 1957 OC-4 and wanted to run a small 12V winch on the back, this conversion did the trick... I didn't change the drive pulley, used the one that came with the alternator (but used the belt you recommended), added another toggle switch for alternator excitement... Would have been an extremely simple conversion except for having to pull the hydraulic pump to change the belt... Pump had rigid pipe fittings and I didn't want to R&R the radiator, so I cut the pipe nipples with a hacksaw to remove the pump... Once I pulled the pump I decided that I didn't need hydraulics, so I pulled the whole system off the crawler... If I ever find a 3 point setup I can buy, I'll reinstall the hydraulics... I would have spent hours/days trying to reinvent the wheel if I hadn't had your instructions... Thanx again, David
