    Hi.

    Was wondering if someone can shed some light on this. The excavator is tracking forward and back ok but wont track forward/left. The issue comes and goes. I just tried it now and its back working again.

    Any ideas

    Regards
    John

    Could be and issue in the brake on that side. Kinda hard to pin point if it won’t do it all the time.

    What does the hydraulic oil look like.? Clear and bright or dull with maybe a white-ish tinge to it.?
    Has the centre swivel joint been resealed recently.?

    Hi nige and db. Thank you for the replies.

    The hyd oil is a creamy colour not very bright. No matter how many oil changes we do it always stays creamy in colour.

    Havent got a chance to do the swivel. If you wait for the oil to heat up..(by raising and lowering the boom) she'll track away fine (except for maybe the tracking left issue)

    Regards
    John

    Creamy colour indicates water in the oil IMO.
    What about the reseal of the centre swivel.?

    IMO* if the oil is water-contaminated it needs to be drained from all the:-
    Cylinders
    Travel & swing motors
    Hoses
    Valves
    Tank
    (* other opinions may be available)

    You may find even with your best efforts that it takes more than one oil change to improve the oil condition to an acceptable point.

    Best is to put gauges on pilots but in my experience it's usually in the travel valve on 200 series
