First post, my topic dont seem to be discussed...
EX100 -3 1995, 9000h
the hydraulics in the levers seem to pulsate, and the whole machine starts to jump, somtimes you can fel that the levers looses pressure if you are using all functions, turning arm and boom and when pressur comes back (it just falls out for a super short millisecond) as you understand it will be a war between what will hget the oil and its starts to be wery unsmooth. just relese the handles and start over.
The pressure to the pilotcircut is about 45bar
the main pressure is 300bar if i remeber correct. +-.
changed out the acumulator for the pilot circut (it was dead) to a new with 25 bar gas, it seems to be 5% worse with a working accumulator. that is just a feeling, hard to say.
been serching youtube, and it looks like all 100-3 is a little bit unsmooth in the hydraulics, but i dont know...
More rpm, wors it gets.
Does anybody hawe any clue where to search? is the 25bar accumulator to low pressure? it shall be about 0,75 x pilotpressure generally in that kind of setup of other machines...
Excuse me for my missspelling, do not speak english normally, lives in the same country where thay say that Santa lives (Finland).
