Guys I am. Complete new to the forum and I need some help with my new 3901 4 wd HST. I have a FEL and BH77 backhoe mounted from the factory. Literally 2 hours on it.
...
Forgive for being a novice and making I'm freaking out for nothing. I just know 100% that this noise I'm hearing did not happen until after I operated the backhoe.
THANK YOU in advance for your help.
Hey,
JimmyT, welcome to the
OTT! Sorry your first post had to be such a traumatic one. I'm not clear -- did this just happen and now you're off to fish for oil, or are you now back home and ready to dig?
In any case, it sounds like your new baby is making a horrible noise that is not actually something going horribly wrong. The first thought that occurs to me is what you've suggested: some leaver isn't set correctly. The second is that the hydraulic fluid may be low (did you check it after the noise started?) Sadly, I'm not knowledgeable about your machine, but I can reassure you that you haven't broken anything, and likely won't. I'm just chiming in here cuz I can feel yer pain, and you don't need to be tearing your insides out frettin about it.
Hopefully some of the gurus will chime in soon. In the meantime, one thing that occurs to me is to tie up the BH and stabilizers, then take all to pressure off them and disconnect the hydro lines. Then drive it and see if the sound is different. (Or gone!) Instead of tying it up, you may prefer to just remove the BH, but I'm the lazy sort who wouldn't want to do that just to check for noises.
The think I'd like to rule out is the use of the BH being the reason the noise started -- were all the cylinders and lines full, or were there substantial voids in the system? It seems unlikely the BH could be mounted and have enough air in the system to cause your tractor to scream when the voids got filled, but that's all I can think of.
Hang on, the folk who know stuff will be here soon!
