    I've developed a very slow leak but enough to cause belt slippage under machine... its coming (what I can see) from the right hydro pump... it looks or guessing its where shaft comes out. Its very minor but its causing oil everywhere under machine Ans causing belts to slip... can this be repaired as I hate to replace whole pump.... where can I get parts thanks

    Their is a shaft seal under the pulley. I had a pump bearing go out on a 152 i am pretty sure the pumps are the same hydro gears check the bearing good. That may be the reason you have developed a leak they are not hard to work on at all my dealer got me a complete seal kit plus bearings just pay attention if you break pump apart. Good luck
