Squeaking when running Bobcat 853 Any ideas?

[neonewman]

I have a Bobcat 853 skidsteer I started it today and heard a new squeaking sound coming from the tractor I cannot tell where yet. It seems to happen more when I operate hydraulics or rev the engine up. It sounds like a belt squeak like you would hear from a car alternator.

I checked the hydraulic fluid it was a bit low so I topped it off but it still was making the sound. Any ideas?

I am asking for some expertise

Have you checked your alternator and other belts?

Have you checked your alternator and other belts?

I will check now

It also has a belt that runs from the engine to the pump. It could need adjusting.

Check all the idler and tension-er pulley bearings

Mine did that it was the Fan pulley. Not sure if yours has one. I have 863.

The 853 does have a fan pulley tensioner. Fairly easy to access once you remove the guard. In addition to checking the hyd pump belt as others have noted, I would double check the alternator/water pump belt though as tension is achieved by the alternator, so the belt will lose tension as it wears. The fan belt tensioner is spring loaded so it's unlikely the cause, unless the bearing inside is bad, but it wouldn't make a squeeking noise (more of a pronounced vibration in my experience)
