Hydro squeals in Forward after warming up

Recommended Posts

Smitty
A hydro squealing in forward only not in reverse on a 7018h. After about 5 minutes of use the hydro makes a highpitched squeal as if bearings are going bad. I can't quite find the source of the noise, maybe gear box? or one of the pulleys? What gives? I can't figure it out?

Are you sure the squealing is not coming from the cone clutch on the mid PTO. I has this problem last summer. Bearing siezing up and spinning the internal sleeve on the shaft. This was on an AC716H (7016H) The only other thing that I know will make a squeal is if the fluid is low and you may be sucking foam into the pump.
