    Hello all, new to the site and bobcat repairs. I have a T190 that has starting issues (from not centering) and major creeping. Pulled the cab up and this is the mess I'm dealing with... its even got some wood in there.. FML any advice?

    the aluminum arm is probably worn out, somebody jammed a stick in there to keep the linkage pivot bolt from catching on the top of the hydrostat.

    looks like a pintle shaft seal is leaking as well..
    get yourself a pair of levers, bushings, cams, new bolts a seat of pintle shaft seals and orings, and replace everything while you have the centering plate off.

    wille has a nice thread on "repairing a creeping bobcat"

    Thanks crewcheif, I ripped it apart yesterday and everything you said is correct. The arm was completely loose and barely catching the shaft. Now on to finding a parts manual.

    I found willies thread and it helped a bunch.

    I appreciate your response, this is all very new to me!

    if you go to bobcat.com find the OPC (online parts catalog) you can look up the part numbers for everything you need. there is no online pricing, nor can you order parts direct from bobcat. a visit to a local dealer is in order.
    one word of warning, pay strict attention to serial number breaks within your model and SN. there have been a couple different variations of lever/cams/bushings

    Can the Pintle shaft seal be replaced in the unit? Do you know of any write ups on the process of how to do it?

    once you have the centering plate, and levers off you'll see 4 bolts around each pintle shaft, removed the bolts and the centering plate mounts, and pull the smaller plate off the top of the pump. seals are set in a counterbore in the plate. the oring (actually a square cut ring) sists in a recess around the outside of the bearing. dont panic if the bearing pushes up a little when you remove the plate, install the new seal and quad ring, and push the bearing back down with the plate.

    And be sure you clean the area around the pintle shaft thoroughly before you remove the four bolts, the centering plate mount and the pintle shaft seal plate.
