I recently changed the hydraulic oil on my tractor as I'd noticed that the Aercore was dropping after switching the tractor off. Didn't change the filter, unfortunately. However, since changing the oil I'm still having issues. I've read a number of posts/threads regarding this and it looks as though air entry is favourite.
Since the oil change the low range selection is very 'spongy' and not positive at all, and the 540E doesn't completely engage (though that could be the linkage). I also noticed that when I had the Aercore in the air on a few revs that, after a while, it started 'bouncing' (intermittent pressure?)
Obviously the first thing to do is change the filter and then check for anywhere where air may be entering (haven't spotted any leaks) and take it from there but I wondered if anyone has any ideas/experience about this.
As an aside, when I changed the oil I drained from both plugs at, more or less, the same time. I got to wondering if, perhaps, I should do them one at a time and, if so, in which order. Any advice?
