655 bad hydraulic noises

dannyidp · Oct 15, 2023

Hey guys my first time getting to use the backhoe since I bought it and done a lot of work on it. The hydraulics in the rear or making an awful noise a little slow and jerky as if it has air. I just rebuilt the boom cylinder but all the cylinders are making that noise. I can't figure out what it is any ideas? Thanks

Is the fluid in your hydraulic tank on the low side.

That was the first thing I checked. I may
need to post a video because I've never
heard hydraulic noises like this and it's
on all the cylinders.

It's likely related to your cylinder repair somehow. It's the how that's frustrating. May be you relief valve in the backhoe valve body. If you don't have a manual, you can look at an online parts diagram. Messicks.com

That sounds like the pump is starving, is the suction filter in the reservoir clean, is the supply line to the pump ok with no kinks or other damage, is the pump drive shaft ok, oil of the right weight.
