    Bobcat 853 movement and hydraulics go extremely weak, seemingly at random

    I actually left the old belt in there but it did not seem too hard to remove. Yes, this was the belt on the right side, it was really tight in there especially with the rusted up bolt holding the tensioner in place, but I managed to get it with a cheater bar. It was certainly more roomy on the...

    Bobcat 853 movement and hydraulics go extremely weak, seemingly at random

    I wouldn't put it past myself, but thankfully this time I didn't screw up that bad! After changing all hydraulic filters and removing obstructions, the issue persisted. Finally found that the drive belt was loose and tightening it up solved all of my power issues. Probably should've checked...

    Bobcat 853 movement and hydraulics go extremely weak, seemingly at random

    My tank only has two ports, one (larger) seems to be going back to the hydraulic pump near the back-center of the machine, the other one is coming up from the case drain filter. Does the case drain filter also pass fluid from the rest of the hydraulics? Or do those not return to the tank in the...

    Bobcat 853 movement and hydraulics go extremely weak, seemingly at random

    Alright, pour filter was indeed swimming around at the bottom of the tank, may have been restricting the flow there when it got sucked into the outlet there. Also, I got the chance to remove one hydraulic filter and tear it apart. I confess I don't really know how to diagnose blockage in these...

    Bobcat 853 movement and hydraulics go extremely weak, seemingly at random

    Yes, it looks like my screen for filling has been busted off. Under the cab It looks like I do have that in-line case drain filter. It does not appear to be listed as a replacement part for my machine on the service decal on the back door. What is the purpose of that filter? I was under the...

    Bobcat 853 movement and hydraulics go extremely weak, seemingly at random

    Thanks for pointing me to this. Got a chance to take a look today at the tank and I could not find any hydraulic suction screen near the bottom of the tank. I do not see that in the diagram here either, but I suppose it could be built in. Maybe I should look in there with a borescope or...

    Bobcat 853 movement and hydraulics go extremely weak, seemingly at random

    I would think I would notice the auxiliary hydraulics moving if that were the case. I have a grapple bucket on there right now so it would be quite visible. I don't think they were maxed one way or the other. I will run out and check that right now. Did not know my 853 had that functionality...

    Bobcat 853 movement and hydraulics go extremely weak, seemingly at random

    Having an issue with a skid steer I bought a while back. I expected to have to do some maintenance and repairs on it since it is a pretty old beast (2622 hours now). I recently repaired a leaky left side lift and tilt cylinder and those no longer go down over time. Ever since I've owned the...
