    Nahh .. thanx mate ... dont go to any bother .. I think what you said about being a few bar out, and the possibility of the guages having error might be the answer .... I'll jack them up to 800 bar and see if that works ... only joking internet people

Even that extra 20bar made an enormous difference to the travel performance.
    Had another EC15 with weak tracks lately and I was speaking to Volvo's top guy for compact stuff this afternoon, and he filled me in with the settings for this job, and I had forgotten this thread existed ... but thats one EC15B back up to spec now.

    The bit Ive highlighted above is indeed very true

    Uffex's post



    sorry to tell you what you most likely do not want to hear, hydraulics are not self adjusting, a few bars pressure difference are unlikely to be reconciled by any operator. Worn machine will have little to gain by any magic adjustment. Real sorry if this is news too U.
    Kind regardUffex

    Yes I'm aware of that cheers

    Its a constant battle we have unfortunately .. keeping a forum clear of unwanted rubbish so that it keeps everything concise and on topic for the readers, means the baby gets thrown out with the bathwater from time to time

    Sadly I've lost his formatting due to my error, and had to paste it under my own post title.

    Spamming has become an art for some software engineers , and we now often get bots that 'comment spam' who look like real posters .. but aren't .. I think were 12,000 posts or so in now, .........all checked one at a time

    Question

    Remember, if your machine is older, or new to you but secondhand [like mine] the pressure relief may have been set lower to hide problems.

    Mine adjusted up to 170 Bar and there have been no problems....yet!

    I only adjusted this one setting. There are 2 others but my little EC15 is working fine, so, ".....if it ain't broke...leave it alone..."
    Following up this thread to post my findings in the right place.

    Quite to the opposite, my -15 has some 3300 hrs on it and when tested, I got 200bars. The machine is a contractor pre owned one, and obviously he's put more power in it. The Rexroth SB-12 block is rated 250 bars and all seems to work right and the engine sounds not overloaded. Should I turn the pressure down to 175bars?
