wheelhorse66 10 #1 Posted July 25, 2013 how strong is a 4 pinion tranny Share this post Link to post Share on other sites
BPjunk 184 #2 Posted July 25, 2013 I have always calculated the 5010 3 piece side plate transmission to be at a maximum of 25 hp (with all new components and the updated differential gear) , the 2 piece UniDrive at 35 hp and the eight pinion with 1-1/8 inch axles at 55 hp going through the transmission before things start to break under a hard pull. Keep in mind that most industrial transmissions are rated by torque (resistance to movement) and not horse power. This should be kept in mind if converting a Wheel Horse to a diesel engine.

Forest Road 594 #6 Posted July 26, 2013 I don't have any experience. But if its your only horse Id buy 4 more pinion gears. I'm pretty sure the diff housing is the same. Share this post Link to post Share on other sites
