T1510 Squealing Sound

ChuckTyler · Apr 5, 2015

Hi Folks. I'm new to this forum, but hope y'all can help. My NH T1510 has 400 hours on it, and noticed today that as I push down on the hydrostat pedal to increase speed, I hear a squealing noise that seems to be coming from the front. If I ease up on the pedal, the sound goes away. It seems to be more prevalent in the Medium and the High Ranges; I don't hear it in the Low Range.
Have any of you come across this?

Thanks,
Chuck

Assuming it's FWD, grease the drive shaft. There are bushings in the shaft that will squeal in they get dry.

Thanks for the info Agriman. I'll give it a good lube job today and see if that resolves the problem.

I just posted the same issue with my JD 4120. Curious to see what you find out. I'm thinking a relief valve?

Sorry, Jmer817, I haven't got to it yet. My wife's 98 year old uncle is living with us, and the last few days have been kinda rough. Hopefully tomorrow. I'll let you know.

Well, I finally crawled under the tractor and it turns out that all it was, was the boot that covered the front U-joints on the driveshaft tore loose and the clips that hold it in place were rubbing when the shaft rotated. Should have looked earlier, but it's tough for this old body to lay down on the ground, let alone get back up.
