baerpath 517 #1 Posted October 10, 2008 Okay I usually stick with the standards for pulling but (ya here it comes) Looking at a new class for next year a V8 hydro class Nothing to far out, nothing over a small block chevy or ford Most are using cubs at this point with a few JD's mixed in. Whats your thoughts will a WH hydro hold upto a V8 ? Or is my sign :imstupid: Duane Share this post Link to post Share on other sites
TT-(Moderator) 1,162 #2 Posted October 10, 2008 A WH hydro will only be as "potent" as the pressure relief valve allows, Duane. (and if you bypass or eliminate it, something else will just disintegrate. ) Perhaps you would be further ahead to run true hydraulic drive. (like Bob Rock's articulated 418 or Mith's newest creation.) :banghead: Share this post Link to post Share on other sites
htopjimmy26 3 #3 Posted October 10, 2008 It is amazing that the sundstrands in those cubs hold up at all I've seen a couple of those small block cubs and I guess they fail kind of regularly[1/2 to a little over 1 season depending on use?] Sounds a little rich for me.[Disclaimer; I don't have any first hand knowledge as to whether or not the hydros can be made to last longer or if this is typical of all cub hydros, or just the couple guys I know.] Good luck :banghead: Share this post Link to post Share on other sites
Docwheelhorse 2,778 #4 Posted October 10, 2008 The rpessure relief valve will dump as mentioned and you won't go anywhere. Bypass the valve and your butt and associated more "more valuable parts" just ahead of your butt will be sitting on a grenade. Tony Share this post Link to post Share on other sites
baerpath 517 #5 Posted October 11, 2008 But are they as strong as a Cub or JD Peerless. The JD only had a 4 cylinder on it from an Izuzu pickup, but it pulled darn good. Has to be a stock type hydro, my other thought was a Case. Duane Share this post Link to post Share on other sites
htopjimmy26 3 #6 Posted October 15, 2008 I think a Case would probably be easier to convert to a smallblock, as I recall they are hydraulic drive using a pump and drive motor metered through a flow controller. Also the motor is oriented crank front to rear instead of left ,right. Share this post Link to post Share on other sites
Kelly 1,033 #7 Posted October 16, 2008 Duane, I have a few Case tractors and lots of parts I could set you right up and yes they are hyd. drive(with a hyd. motor running the trans) not a true hydro trans, so I don't know if it will fit in the class?
