I know all manuals on the machines specify to replace the hydraulic oil periodically. Most at around a 1000hrs.
However is flush the system damaging?
Here is what i have experienced
I reasently bought a used ASV. Before buying it, i had the oppertunity to work the machine all day on a job.
At day end i had a good look over the machine as i new i might be buying the machine. On oil leaks i found only 2 of the rams leaking oil(everything else was dry).
After the purchase i had the machine at an ASV expert for some repairs on the undercarrage, it was ponted out to me the badly conatamined hydrailic oil. They then flushed the system several times. (See the picture of oil samples as provided to me). This all seemed like a good thing.
However 1st job out, after the simi-rebuild.
Now a lot more oil leaks
4x of the rams was o/hauled in the rebuild, the remainding 2 rams started leaking. That means all 6 rams started leaking.
On the bottom transmission showing leaks
One of the hydraulic drive motors started leaking badly(the ASV specialised suspecting o'rings in the motor as the cause of oil leak).
I started with only 2 rams as oil leak, now multiple leaks. The machine now have knocking sounds if operated on a bank (the leaking side of the track)
What could have caused this?
Was the flushing of hyfraulic oil the cause?
On some motor vehicles i know the differentials oil will be specified to be topped up only, as complete drainage or flushing will cause failures in the unit.
Is this what is happening to my machine?
