I've just removed the 853 engine, hydrostatic system and fuel tank. I replaced the two o-rings on each neutral steer spline and shaft assembly (which was a very easy job BTW), repaired the fuel tank and reinstalled the whole thing. The neutral steer assembly leakage problems are corrected, the neutral steer is adjusted to the best its ever been, but now I notice that I'm having to push more left stick than right to travel in a straight line. I pretty sure I've seen this addressed in the service manual but can't for the life of me find it again. Does anyone have any experience with this (hopefully just an adjustment)? Any input is appreciated.
