    Caterpillar 226B drive joystick testing

    Hey, my machine is a 2008 with 2700hrs. The left joystick is very slow to react and also overreacts. The right joystick is perfect and works like a charm. Both have very slight external sweating, but nothing I would consider a “leak” From forward to reverse or reverse to forward, it has a full...

    Bobcat 435 slow and weak travel

    Hello again. My 2007 bobcat 435 has seemed like it has weak travel since I have owned it. It travels pretty straight, but struggles to turn in high or low. You can feel it shift from low to high, so I dont think its stuck in high. With the tracks in the air it free spins quickly, and it travels...

    2014 bobcat t590 10w30

    I have a NH 218 skid steer that the dealer recommends running 10w30 for the hydraulic system. Is it ok to do the same in the bobcat t590?

    Leaking Tilt Cylinder

    I just installed a complete seal kit on this tilt cylinder on a Hyster H150F. It's leaking a smaller amount from the threads in one spot (yellow arrow) where the cap screws into the end of the cylinder. It only leaks when the cylinder is going out (tilt forward). What could I do to fix this?
