    First a little background
    I have a Toro Z Master Model 74225 62" SFS. It is approximately 4-5 years old. I bought it used last year from a person I know takes care of his equipment. Yesterday, my crew leader was operating it and felt the right rear wheel wouldn't turn. In a quick review he thought that a Hydraulic hose was leaking. A closer look at the shop showed that the pully going inside the right Hydraulic pump was knocking and not stablized. One of the guys that works for me, has some background in mechanics suggested that it may be a blown seal and bearing.

    My dilemma and need for advice.

    I called my equipment supplier (whom I trust) and he gave me the name of a mobile mechanic who specializes on industrial equipment. I called him and described the problem. He indicated that the Hydraulic pump would need to be replaced along with the wheel motor on the right side. He told me that if you just replace the pump and not the wheel motor evidentally you would need to change the wheel motor and then a vicious cycle would begin. He indicated that its best to replace both parts and clean out the lines and replace fluid. I'm no expert so I just want to get some other opinions, experiences or insights on what you think about what this guy is suggesting.

    The pump model is BDP10 .

    Thanks to all that offer any suggestions or comments.

    Let me use this as a example Danny,If the seal in water pump on your truck started leaking would you replace the Radiator also ?
    The Mobile Mechanic is right about one thing, The hydro system MUST be cleaned and flushed THOROUGHLY even removing the tank and washing clean.
    I would not replace the wheel motor in this case.
    Now you have another problem, If you ask this Mechanic to replace the pump only and he looses the money for a wheel motor replacement will he do a proper clean job on your system !
    And the fluid should be changed again after about 5 or 10hrs.

    Good Luck !
