I finally bought, for my S130, the 607 backhoe along with auxiliary rear stabilizers. The 607 works great but after the bobcat engineer installed the extra hydraulic "plumbing" kit needed for the rear stabilizers, the Bobcat then produced when I started the engine a loud nasty " vibrating buzz" like sound in the hydraulics, this sound would stop only when I would slightly increase the engine rpm or activate any hydraulics. After complaining to the Bobcat people they told me I needed to buy, in order to stop the sound, a "hydraulic muffler". So I did, got it installed… but it changed nothing! So my question is, I want to remove and return this expensive muffler but I need to know if this sound is normal and I will then have to learn to live with it or on the contrary that it is an indication that something somewhere is taking "a beating" and will therefore wear out/break faster than it should… in which case what should I do?
