Dump Bed Buzzing Sound

[mtnxtreme]

When I raise the bed on my 2012 5600 Toolcat there is a buzzing sound coming from the bed. Anyone have any ideas. Only when raising the bed. All other hydraulics work quiet.

is it possible there is a restrictor in the line to slow the speed? if you raises slower does it still do it?

It does it as it痴 going up and still when I stop raising, if I just tap the lever towards down, but not actually lower it it goes away.

when you stop raising the bed there should be no flow of fluid, if you stop raising half way up and release the lever does it still buzz

I wonder if it is the bypass valve. I've noticed the same thing on 3ph - Lifting something has a slight squeal and even when it's up the squeal continues. A slight bump down and it doesn't squeal anymore.

Exactly! Yes it still buzzes !
