    Bobcat e20 blade dropping

    No sir youd see it in the prints. Could be any number of reasons they chose to fit that to the machine

    Which way does this seal get installed?

    Looks like it was flattened out from being in backwards and rotating. They typically have a gradual taper, not a ridge like this one. If you’re not in a rush maybe wait for a seal. Easiest way to put those spring seals on is to slide it over the shaft first, and then tap it down into its...

    Bobcat e20 blade dropping

    You should'nt have an issue, aside from what you've described if that is the fault. If you do start tearing things apart, make sure to keep things clean. Normally the cavity in the track frame where the swivel joint is located is packed full of dirt, which you don't want entering your hydraulic...

    Bobcat e20 blade dropping

    Typically this is due to a bypassing swivel joint, but it should be confirmed before you actually tear it apart. There are different ways of testing it of course, but in the past ive hooked a portapower to the supply line feeding the side of the cylinder that is losing fluid / the direction of...

    Sullair 185 Compressor stalls

    That makes perfect sense to me, I just can’t see how / what operates the clutch, or if the clutch is even functioning. The more I think about it the more I’m starting to think the compressor isn’t being unloaded.

    Sullair 185 Compressor stalls

    Hi bill, eastern Canada so somewhat of a mild winter. Average temp of maybe -10 c. That said, it’ll get to -30c for a week or so normally every winter. It’s now a manual choke. There was a check valve and filter in the carb bowl to keep fuel from draining back to the tank that was jammed...

    Sullair 185 Compressor stalls

    Good day, I’ve an older (80s model) compressor that stalls when cold. To allow the machine to run, I’ve got to crack open a hand valve to take the load off the compressor. Once everything is heated up (15 minutes or more) I am typically able to close the hand valve and the compressor will run...

    Pintle / Lunette ring selection

    I am in the process of building a 20+4 deckover equipment trailer. At the moment I am putting 2 7k axles under it as I have them as spares, but may somewhere down the line put larger axles or a third axle under the trailer. I am tryin to decide between pintle / lunette rings. I can’t decide...

    JR, https://www.parker.com/literature/Literature%20Files/hydraulicpump/training/Acrobat/Industrialtrainingtemplatebasics.pdf Good bit of information there if you’re curious. “Parker” is a fluid power equipment manufacturer. Basically all the hydraulic equipment in the facility that I work at...

    Troubleshoot excavator not tracking straight. Yanmar VIO 50

    JR, The way I look at it, if the pressure compensator is capable of being cranked “all the way up” then the pump must be designed to output that pressure / flow. I can’t imagine these pumps were designed for your machine only so the manufacturer has to give the end user the capability to match...

    Troubleshoot excavator not tracking straight. Yanmar VIO 50

    JR, I haven't had the chance no, have been working the machine. I did crank the pump up some more though. If you push enough material with it i imagine i can just about get it to stall, so i just go easy on it. So far it has dug 3 utility trenches and grubbed and levelled a yard. Not being able...

    Troubleshoot excavator not tracking straight. Yanmar VIO 50

    Good to hear (kind of) JR. Too bad the pump is on its way out, but maybe you can find something in the mean time while you can still run the machine. I'll just reiterate my symptoms- - Lack of power when tracking / pushing material - No difference when high speed is selected while traversing...

    Troubleshoot excavator not tracking straight. Yanmar VIO 50

    Uffex, In your experience, what have you seen as the normal/typical cause for a reduced flow capability of an axial pump? Is it more often that the valve plate becomes worn? or is it that the pistons or their bores become worn, causing a reduction in flow?

    That sounds like good advice to me. I will be doing that to my machine once I’ve had a nap after my backshift. How many hours on your machine JR?

    Also, on the end of the valve bank should be a sticker with the manufacturer of the valve bank. Mine was made by “Wabco” I imagine you’re may be the same.

    Troubleshoot excavator not tracking straight. Yanmar VIO 50

    Not a clue. I can’t seem to find much aftermarket for mine, mind you I haven’t called the dealer. That said, when I priced the swivel seal kit, dealer wanted 650$. Found a genuine NOK seal kit online for 250$ cad. I know that komatsu had a pc27 of the same vintage that is an identical machine...

    Troubleshoot excavator not tracking straight. Yanmar VIO 50

    JR, I just got in from doing the same thing. I found nothing out of the ordinary in regards to the spool. That said, I was checking the main control valve, not travel motors control valves. You can see where it has rubbed in normal operation but nothing you can catch with your fingernail. The...

    May be able to put the tank under vacuum?

    Jrhook perhaps this could indicate a leak on this section of the valve? May be worth pulling the spool and seeing what it looks like. The farthest passages on either side go back to tank.
