    I've got a hydro pump that when it runs for about 5 minutes and warms up starts sputtering. I just replaced the wheel motor it had a broken shaft, and drained the system and put new oil and filter on. It runs great when its cold. Anybody have any ideas? The only thing I can come up with is maybe some debris ended up in the pump.

    Since one of your wheel motors failed metal shavings from the motor going bad may have ended up in your pump.

    Is the pump on the same side as the failed motor was ?
    And did you change the hydro filter when replacing motor and fluid ?
