    bobcat 853 hydrostatic pump leaks heavy between right and left side

    Thanks for the tips, I will try and get into it to check the wiring this weekend. In the meantime, I've seen where others have installed a pressure gauge on some sort of T so they can monitor charge pressure in the system from the cab. Can anyone recommend a kit to do this?

    bobcat 853 hydrostatic pump leaks heavy between right and left side

    Latest update. Played with the machine a bit over the weekend. First thing I noticed was the Red Transmission error light pop up after using the hydraulics for a few minutes (not BOSS equipped) in the good manual it says this "The transmission warning light comes ''ON'' when hydraulics are...

    bobcat 853 hydrostatic pump leaks heavy between right and left side

    Thanks to this forum My 853 is back alive! No major issues putting the pump back together and the engine back in. The M46 pump gasket kit I bought did not have the correct O rings that go in between the right and left side pumps so I had to order them directly from bobcat (as well as the two...

    bobcat 853 hydrostatic pump leaks heavy between right and left side

    Got my pulley off last night, what a bear! MAP gas wouldn't get it hot enough and had to switch to some light torching then some hits with a hammer and it finally popped off using the good puller. One question. I bought a new fuel pickup line to replace as was mentioned earlier in this...

    bobcat 853 hydrostatic pump leaks heavy between right and left side

    Got my engine out yesterday and found the cause of the leak. the drive pumps only have the two bolts holding them together, well the bolt on the backside (next to engine) is broken off, I can see what is left of a stud. Not only that bolt is broken but the mounting bolt for the entire pump on...

    bobcat 853 hydrostatic pump leaks heavy between right and left side

    Thanks for the insight!!! I hope to have my motor removing jig built by new years. I've got a cherry picker to get it out but no forklift etc, so going to build their tool and do it right. On the case skidsteer tandem pump I previously did, I pulled it out, fixed a broken shaft in the center...

    bobcat 853 hydrostatic pump leaks heavy between right and left side

    wow, many thanks for the tip. Ive pulled a tandem pump apart once for an old case skidsteer but i'm no expert on this. Is that pin something that will just fall out when I split it or if I am careful will things stay in place so I will know how to put them back in? I dont plan on doing a...

    Update, found a newer service manual (rev 1996) that shows some of the pump breakdown. Much more helpful. Bobcat dealer will not rent or allow a borrow of the engine removal tool so I guess I am stuck building one.
