I am far more familiar with 751 & 753 machines, but I would assume they are at least somewhat similar. SO, with all of that said, I would check the lever arms & linkages that connect to the pump itself. If the seals are not leaking, leave them alone. The issue you are most likely having is a issue with the spring operated 'swash-plate" no longer able to return that control to its neutral position. That is what I have found on TWO 763's (I've bought recently) have both had this exact issue. What I had to do was replace the arms that mount to the pumps shafts. I've had problems with both 763's on the left side only, but while I inspected the other side, I found the same lever arm worn too loose to consider fit for service. SO, I replaced BOTH (2) arms, the bushings that press into them & the bushings that mount in the other end of the linkages, too. After doing that, I jacked up the machine until all FOUR (4) tires were of the ground and it was placed on sturdy jack stands. Then I (very carefully) started the machine (with the cab raised), lowered the seat bar and then pressed the "traction - lock" button. By doing so, I could observe the machine while it should be in NUETRAL position at idle engine speed. After I did ALL of this, I noticed neither side was 'centered' & they both wanted to do the own thing. SO, I adjusted the left side first until it no longer moved, with the engine still running. Once that side was all squared away, I adjusted the right side the same way. (It takes some time to get it just right, as there is no simpler way to set this new neutral position.) Now that the neutral position is reset, then you can adjust the linkage adjustment. By adjusting the linkage length last, you can ensure that the machine has a similar forward & reverse speed. By doing all of this, you will most likely have a great outcome. (NOTE: Try to remember that this is your very first time doing all or some of this, so PLEASE GO SLOWLY! By going slowly, you can make sense of what you are adjusting & why this procedure works the very best!!) Keep the machine safely off the ground until it is adjusted perfectly. If you get flustered, step away from the machine to better keep your bearings.</p></blockquote><p></p>
