    Tilt cylinder wont hold position (853)

    Ok, changed the sensor and AF2 and AF6 will no longer been shown. Control valve and steering spools are no longer leaking, however, there is an other oil leak i have to find. Would assume there is something between the engine and the hydro pump. Will check that when i'm back home (2 weeks).

    Tilt cylinder wont hold position (853)

    Tazza, thanks for the answer. I already checked the wires from the sensor to the BOSS unit yesterday. I had a little bit time after work today and removed the sensor. When i short the wires, BOSS no longer shows AF6 so the sensor switch has to be closed when engine is off. (As shown in the...

    Tilt cylinder wont hold position (853)

    Installed the seals today and it seems to be ok, will see when i will work a bit with the machine. However, BOSS now shows AF2 (Air Filter) again, both filters are new. In addition is shows AF6 (Air filter sensor). Does someone know how that sensor works, there is no description in the service...

    Tilt cylinder wont hold position (853)

    had a few hours today after work so i drained hydarulic fluid, removed the hydraulic tank and removed the spool for the steering levers at the hydrostatic block. I'm wondering that there are no o-rings on the spool: I dont really understand the drawing on pdf page 93 of the parts list. Should i...

    Tilt cylinder wont hold position (853)

    sorry, can not post pictures, i dont have a windows pc with office in my workshop. I have removed the cab, the lift arms and hand controls to work on the control valve. I also have a small leak at the point where the steering levers join to the pump (both sides) (as Tazza has already assumed)...

    Tilt cylinder wont hold position (853)

    thx. I have not counted the hours. It is only for my private use otherwise it would not make sense at all. Btw, ordered the rubber boots and got new filters, will try to fix the control valve next weekend.

    Tilt cylinder wont hold position (853)

    Thanks for the answers. I had already cleaned as much as possible before spraying. The power wash was only for the remaining that were not reachable before. However, in the meantime i found at least one leak, it is the control valve (near part 37/38) 2 Questions: For the seals i plan to order...

    Tilt cylinder wont hold position (853)

    Hi, no post for a long time but i have made some progress. After ordering the new seal kit for the tilt cylinder, i decided to make it look a little bit better than before, this is how it looked like (i have not made photos before started to dismount) There was "a little bit" dirt in the...

    Tilt cylinder wont hold position (853)

    Yes, the nut was loose, see pics: First had to build a wrench to open the cylinder it was fairly easy to open the cylinder. The piston main seal is broken (assume part 5), there was no o-ring ? The nut holding the piston was loose, i could remove it by hand. I hope this one will work again...

    Tilt cylinder wont hold position (853)

    Thanks for the hint, removed the cylinder and tried it with air (about 140 psi) and there is a huge internal leak. Will try to open the beast before ordering a new seal kit.

    Tilt cylinder wont hold position (853)

    My tilt cylinder works and has power in both directions. However, the cylinder wont hold its position (both directions) even if not loaded. I would assume the cylinder is leaking internally. Could it be some other fault ? I plan to test as follows: disconnect return (down) line from the cylinder...

    Bobcat 843 engine type

    ok, thanks for the hints. Today i made a trip to the netherlands to have a look at another 853 with 2300 hours. Everything seems to work ok. This one was also equipped with a isuzu engine but a different one than in the 843. Due to the fact that this one was sold for the same price than the 843...
