    Hi Everyone,

    I have an older model Encore Z48.

    It has the BDP 10-L-117P hydro pumps.

    I have an issue where after about 15-25 minutes of use (assume after the oil heats up?), I experience a power loss on the right wheel/hydro only, I also hear a chattering sound while either going in reverse or forward. I can't tell where the chatter is coming from - pump or wheel motor. If I hold the lever there, eventually power gets there, just takes some time and the chatter goes away.

    I can’t figure out where to start from here. Wheel motor or hyrdo pump. Mostly because it works great for the 1st 20 minutes, It almost seems like the oil heats up and starts to slip past an o-ring.

    Things I have done:

    Changed the belt
    Changed the hyrdo fluid and filter - It was clean, no metal.
    Checked all hoses for tightness and leaks, nothing to be found.

    Any suggestions on where I should start?
