Shuboxlover 478 #1 Posted March 30, 2011 Been messing around trying to get this thing going that I picked up a while back. I got the engine running (K341), the mid lift and the three point lift go up and down easily, but the thing won't move back and forth. Can you have one without the other, meaning if the lift cylinders work, should the tranny work, or is it separate from the lift cylinders? The tranny's oil is full. :thumbs: Share this post Link to post Share on other sites
canam1991 2 #2 Posted March 30, 2011 Is the hand lever shifting the pump forward and reverse? Share this post Link to post Share on other sites

stevebo-(Moderator) 8,351 #4 Posted March 30, 2011 Sounds like the pump is working however the shaft/coupler is your issue. Share this post Link to post Share on other sites
Shuboxlover 478 #5 Posted March 30, 2011 what is that, where is it, and how do you fix it?...... Share this post Link to post Share on other sites
pfrederi 17,868 #6 Posted March 30, 2011 If the lifts work I would guess the connector (Engine to pump) is not the immediate problem. There are several easy to follow diagnostic charts in the Sundstrand Manual. That would be where I would start. Is the push valve closed ??? I Share this post Link to post Share on other sites
Shuboxlover 478 #7 Posted March 30, 2011 :D ummmmmm......aaaaaa......... there is a teenie tiny little thing called the "tow valve" (that I apparently opened last fall) which I forgot to close.

Kelly 1,029 #8 Posted March 30, 2011 Don't feel to bad I just did the same thing, with the C-160 I just got running hopped on and no go, I was bummed thinking it had a bad trans, then a light bulb went on, I opened the tow valve when I bought it to load it last fall.

halbert 0 #9 Posted April 5, 2011 Just for the record: There are two different pumping elements within the one Sundstrand pump. Both are driven off the same input shaft. 1.) There is the main hydrostatic pumping element composed of a variable displacement, axial piston type pump. This pump can be varied from zero to maximum displacement on both sides of zero--one direction is forward, the other is reverse. This pump is referred to as a "closed loop pump", meaning that the oil moves from the appropriate discharge side of the pump, through the motor (which is a fixed displacement, axial piston motor) and then back to the other side of the pump in a Share this post Link to post Share on other sites

halbert 0 #11 Posted April 5, 2011 pfrederi, I see you have a D200 "FEL"... I've been racking my brain, but haven't figured out what the "FEL" means. Enlighten me if you don't mind. Though I've been a member here since '07, I haven't been very active and am on a learning curve. Thanks, Henry Share this post Link to post Share on other sites
