    Ok gentlemen, I have to respond to this. Firstly, I may be new to posting here but I am in no way new to reading here. I'm also not new to life nor machinery.

    My 1992 580sk swing..

    I go away and think for a while ,then come back...lol. So it seems like something's wrong with my cylinder rebuild(s) or.. As alrman has repeated...the valve rod needs adjusting in small increments to find the happy spot. Maybe my cam and pin work has thrown it out of whack. If the plunger in...

    My 1992 580sk swing..

    Yes this is a true statement, although I did Pull the top boom pin and weld and resurface it for wear, install a fresh alignment bolt, pull and repack the pivot and install a new cam bearing. I did not loosen the jam nuts nor adjust the link from the pivot to the valve at all. As it wasn't damp...

    My 1992 580sk swing..

    Ok ,so I went back to my service manual to the sequence valve section and I have been in there before and now realize again that the short coming here is a lack of theory of operation. I did look for a kit and I read on the forum of a connection to find one. I could definitely do a rebuild on...

    My 1992 580sk swing..

    many years ago I had to learn how the double tilt cylinder set up worked on a Cat D6C from the early 70's. There were flow directing one way check valves that had been chucked out during a replumb on the blade. Nobody realized how the set up worked. I didn't know what these check valves were at...

    My 1992 580sk swing..

    Thanks a lot to all you guys taking time to jibber about my issue. I always tell guys at work I don't have answers, .I only have ideas. I can't fix my computer either lol. So,yes I do agree that one cylinder could cause a drift in theory but I have to agree with tinkerer here.. a lot of oil has...

    My 1992 580sk swing..

    Thanks for your remarks. Everything I know I've learned the hard way . 60 yrs old now with two red seal trades and 44 years of tying up boots. Perhaps you'll be kind enough to put some links here regarding melben's numerous posts ?

    My 1992 580sk swing..

    so as I wander around pruning...in order for this "neutral" scenario to occur wouldn't both cylinders have to have a problem? as they both work in unison .. one pulls while the other retracts. I can't possibly have made a boo boo on both...

    or a stuck relief somewhere.... I'm not too sure who posted it but I did read on here that someone had a number of problems with these sequence valves...but no detail

    My 1992 580sk swing..

    Hi Melben, thanks for taking the time...Respectfully, I have quite a number of cylinder rebuilds under my belt. I did search out and buy what I thought to be quality kits as I don't want to be redoing because of crappy bits. I did inspect the pistons and the bores closely while performing the...

    My 1992 580sk swing..

    Hi there, I've just finished doing a bunch of work on my old backhoe including rebuilding my stabilizer and swing rams. Now I have an issue with the swing go figure. Yes the cam and bolt and pivot are all good and I have installed a new cam pivot bearing as well. Great! no more leaks but... now...

    Thanks for that...Ugh. not sure I'm going there. My old digger is used mainly on my 5 acre property now. I'm 59 now, my eyes are shot, knees are bad and no young fellas around to lend a hand! lol. Why did these spacers fail? Someone stepping on the diff lock under way? I'm going at the e-brake...
