    Anyone have a hydraulic schematic of the Hi-Low system on a 3140/2940 or similar? I want to know the flow paths in the top cover/valves. Thanks

    Kobelco SK200mk5 travel motor

    Anyone know where I can source a good, inspected, used travel motor for a SK200 mk5, YNT0568. Just need the rotating group with valve plate. I believe it's the same motor as a SK210 mk5, I'll dig through my book for the #s off the final. I tried getting parts for this a few years ago, H&R...

    07 Bobcat S130

    First time having the joy of wrenching on one of these little buggers, I used 2/3 of the curse words in my dictionary... The cheesy hyd cooler push connect fitting popped out on the RH side of the cooler while he was running full throttle, pumped copious amounts of oil straight into the...

    Zx60usb-5

    I try to stay away from these newer machines but a customer of mine has a 2016 Hitachi ZX60USB-5, it is off warranty, only got a one year warranty on a $100k machine! Yikes! John Deere must have had something to do with the diagnostic end of things, the display is locked, alarm sounding...

    Rode hard, put away wet..

    Acquired a new project, not that I need anymore but everyone needs a Swiss Army knife! Straight 410 Deere John, has 12" and 30" dig buckets, overall well worn and extremely farmerized, just the way I like... Pretty straight though! Hadn't run in 12 years, all fluids look good, nothing...

    Does anyone know the part# or a source for the C.V. joint at the base of the steering column shaft? I believe all L series have this same joint but not having any luck finding one. Thanks for any info, Greg

    New to me JD 790D LC

    Howdy! Been away from the forum for a while, bought a quarter section of raw land recently and just got a 790D to clear etc with. She's a project but overall in decent shape, it's a very basic machine (no electronics) which I like!! I'm wondering if anyone out there has a wiring diagram...

    Grey market Komatsu Pc75uu

    Worked on this little hoe for an older gentleman the other day, the boom and stick were locking out constantly and code 34 was showing (defective offset potentiometer) I traced the wiring and fixed a bad connection, but noticed that pot took a hit at some point (I should have checked the...

    Back Killer 963C

    Just finished a nightmare job on this stinky garbage pig of a 963C, 6 out of 12 manifold bolts broke flush with the head, manifold was warped close to 1/8" from being run so long, soot everywhere! Luckily I only had to drill out one stubborn bolt, all others came with an ez out, which was good...

    963b.....

    I wish these machines worked in the nice clean dirt. But they don't... I haven't worked on this 963B before, one of the cooler lines rubbed through the clamp above this tank in the rear, thought the pan was just full of crap from the top, haven't seen a tank like this on any of the other 963's...

    Service/PM Stickers

    Wondering what you guys use for service stickers, I've used little sticker machines which I find tedious, and static cling which stay on some of the time. I always write on the filters the due at hours with a sharpie but that isn't good enough for some operators. Any recommended sticker...

    Volvo A25C No steering

    Howdy! 1997 Volvo A25C Ser # 5350V61047, has no pressure for steering while sitting, when moving the ground dependent pump kicks in and steers fine... Is there a priority valve that could be preventing flow from the engine driven pump to reach the steering valve? The truck is 500km away from...

    2002 963C drive problems

    Hi, This 963C (Ser no. 0963T2DS02599) which has the brilliant non tilting cab is causing grief. When turning hard either way it stops and the idiot light flashes, put it back in neutral and it comes back to life, as long as you never fully depress either steering pedal it will run all day with...

    Kobelco SK200 Mark 5

    Hi, I need to know the approximate weight of the counterweight on an SK200 Mark 5, both RH bolts are broken off and would be much easier to get them out with the counterweight removed and upside down. Worst case scenario I'll use an old 980C, she'll lift it ha ha! Thanks, Greg

    Sad Volvo EC210 issues, and more issues

    Howdy! Been lurking around for a while, finally figured out the security caption thing and joined up! Working on a 05 Volvo EC210 with the D6D electronic engine, no power, can stall it before it goes over relief, continuous black smoke even under slight load, found the obvious stuff, pressure...
