High Pitch Whine after removing and replacing loader and lines (2010 Boomer)

KnottsIslandNH · Apr 7, 2014

I disconnected my front end loader before going on deployment and once I got home I reinstalled it and at high rpm 1500-2500 it has intermittent squealing/whining. And I can't seem to figure it out. I hope one of you guys has a clue before I have to take it to the dealer for trouble shooting.

Hydraulic fluid level is good ?

We need a little more info. Does it whine when you just rev the motor or do you have to be moving or do you have to be using the loader. The first thing I would do would be to unhook and rehook the quick couplers.

Ok Fluid level is normal. And its fine at idle and when sitting still with it revved up its fine. But as soon as I start going and give it gas it starts whining on and off. It whines for a bit then fades out then comes back. I disconnect the loader and it didn't make a peep. Reconnected and it started again. I have a new Hyd filter that I'm going to change and see if that helps but I'm not sure. The tractor has 168 hours on it. When its whining using the loader doesn't effect the sound.

Do you have the hydraulic connectors inserted all the way on all of the couplings, and do you have the right on in the right hole? That isn't a smart *** question just a possibility.
