450 hydraulic noise

Chester5731 · Sep 13, 2013

The hydraulics make a buzzing noise when the tractor is idling. At a fast idle it goes away. It is worse after the tractor has been runnig awhile. When cold it is not too bad. Where do I begin to look. I just changed the oil and put a new screen in the reservoir.

I have the same noise on my current 400 along with
the previous 300 and 400 I owned. From my
experience and what I have learned from others,
its completely normal. As long as your fluid and
filter are clean, and the pump does not get super
hot/sound like its laboring all the time you
should be good to go.

On another note, there is a small orifice and
screen in the pressure regulator block, would not
hurt to make sure that is clear as well.

Thanks alot for the insight. I will check the screen before I run it too much more. I just wanted to make sure I don't ruin an $800. pump.
