[QUOTE="Rojas, post: 31711, member: 2183"] In the second picture the fan appears to be sticking out of the plenum and there is a large gap along the back edge. Honestly, you wont stand a chance like that. The water jackets in the head were notorious for cracking in that little Kubota when you overheat. I would hate to see all your work spoiled. Take a look at the Derale 16928 dual fan setup. I know these fans work at high static pressure and you might stand a chance with something like that. Allot of small block V8s using that setup with no problems. That fan draws over 500 watts however, so you may need to upgrade the alternator. If that wont fit on the bottom side, the same fans are available individually. You could build a sheet metal plenum and mount them on the top as pushers. On the salvage side, I believe Lexus used a hydraulic puller fan on some models.... What do the factory parts run from Bobcat? Surely there's a salvage 743 setting around somewhere. [/QUOTE]
