    JLG LJ500 Little John stand-on mini skid steer

    Also, from one of the threads I posted a link to in the first post- this valve might work with some fabrication if the Duke's can't be rebuilt...

    JLG LJ500 Little John stand-on mini skid steer

    Did I send you the manual and parts manual? I can't remember. In any case, I replied to your PM. I'll post the info here as it's relevant to others who might be having this issue. The Duke control valves appear to be rebuildable, but there's not much to them. Looks like maybe just a couple of...

    JLG LJ500 Little John stand-on mini skid steer

    It's got an 11hp Wisconsin Robin single cylinder, pump is a Webster, 3 section, gear type. Drive motors are Nichols 12.9 cubic inch, Duke Control vavles, open center, 2500psi relief. Machine weighs about 1200lbs. From what I can gather, the pump can flow up to around 9gpm, maybe a little more...

    JLG LJ500 Little John stand-on mini skid steer

    Interesting, there's an LJ-500 on ebay right now for sale in Vermont for... *gulp* $5500. Makes me feel like I got a damn good deal at $300. :) Note- the one in the eBay listing is missing the auto-leveling linkage for the bucket. It's modified for a different cylinder. Looks to be done well...

    JLG LJ500 Little John stand-on mini skid steer

    Yeah, they're pretty neat. I find that instead of using it for myself that I end up trailering it someplace else to use it for whatever reason. Or if I have to fit into a tight area. It doesn't get used often, but when it does it renews my affection for it. Snag a pic and post if if you get a...

    JLG LJ500 Little John stand-on mini skid steer

    That's excellent! Aside from compression and timing, you need three things to run. Air, spark, and fuel. If something is heating up and causing the engine to break up, I'd look toward the coil maybe? With a brand new engine that's odd. I'd LOVE to put a 20hp Honda on mine, the extra...

    JLG LJ500 Little John stand-on mini skid steer

    Hey, been really busy lately without much forum time. I have a manual for it, if you send me a PM with your email address I'll forward it to you. I ended up using regular 10w30 engine oil, as that's what the manual calls for. As for your machine nearly dying as it gets warm, check spark...

    So I went to rebuild this cylinder (tilt/curl) two nights ago, it seems like the parts kit is incorrect. Maybe JLG recycled the part number or something. First kit was perfect, lift cylinder is strong as it should be. The tilt/curl is weak, really needs a rebuild. I'll have to bring it to a...

    Forgot the pic of the pin that popped like a shotgun: If this isn’t the poster child for “install a grease fitting!!!”

    JLG LJ500 Little John stand-on mini skid steer

    20T press popped the pin after I put my weight into it. Sounded like a shotgun when it let loose. I’ll have to clean up the pin and bore. Couldn’t get gland nut off at first, 36” pipe wrench with a cheater bar and my 150lbs on it cracked it loose. Next, repack the cylinder and reinstall...

    JLG LJ500 Little John stand-on mini skid steer

    Little more work to the mini skid steer. Got the tilt cylinder removed. Upper pin is seized BADLY. Hopefully it'll come out in the 20T press. I don’t want to mushroom the end. I’ll put a bit of heat on it to warm it up if need be, after I disassemble it. It’s so worn I can move it with my...

    JLG LJ500 Little John stand-on mini skid steer

    Not sure if anyone is actually following this, but it’s nice at least for me to keep a timeline of what I’ve done with and to the LJ500. Last night, in lieu of a Nor’easter, I decided that it’s been left out in the cold for long enough. The tarp was getting tattered and I figured that if I’m...

    JLG LJ500 Little John stand-on mini skid steer

    Pulled this old sled out to sell it. No problems at all... pushed it right onto the new owner’s trailer. Really loving the light weight and four wheel drive on this thing. It’s handy. Slow or not, it’s staying with me! It marks up the lawn but doesn’t make ruts like the MF35 does. Also much...

    JLG LJ500 Little John stand-on mini skid steer

    Snagged a cheap doghouse to modify for my generator (seen in background) Also sold my old (junk) pickup. Sad to see it go, but it was long dead, parts only, sold for more than twice scrap value so I’m happy. The brakes were all locked up, the LJ500 lifted the front corner one side at a time...

    JLG LJ500 Little John stand-on mini skid steer

    Put the LJ to work a bit this weekend, not much, but it sure is better than a wheelbarrow! Random piece of concrete (apparently with an embedded pipe!) that has bothered me since we bought the property. Makes a nasty bump with the zero turn: Pried it up with a railroad bar after a good...

    Haven't fixed the broken zerk yet, nor have I rebuilt the curl cylinder (though the more I use this the more it's very obvious I have to get on that!!) I did, however, use it to move a dead deer found in my back yard. It was nasty, I'll spare you the details. Scooped it up, covered it in lime...

    JLG LJ500 Little John stand-on mini skid steer

    Got the cylinder mounted, used a 10.25” long x 1” pin to secure the top of the cylinder. Made a neat little captured setup out of it. It’s not 100% square but I *needed* the machine today so it is what it is. First time I’ve fired up my plasma in a while. Hand cut and smoothed with a flap wheel...

    JLG LJ500 Little John stand-on mini skid steer

    New pin is on the way. Not greaseable, but I think I’ll drill the rod ends for grease zerks. Maybe... Good news is I found packings for the lift and tilt cylinders and they’re actually correct. Not many pics because of time constraints and being covered in oil, but here are a few pics of the...

    JLG LJ500 Little John stand-on mini skid steer

    Got it going yesterday. Put the carb back together and bolted it on, put the new (used, but good) gas tank on, put some fuel in it. Took the battery off trickle charge (it was dead), bolted it in and bumped the key. It came puttering to life. First impressions- I wish it moved a bit quicker...

    JLG LJ500 Little John stand-on mini skid steer

    Got a few minutes and snapped more pics of the (potential) donor engine. Carb is in great shape, it’s got the right air cleaner housing on it, the tank is clean, the filter bowl/screen is clean, overall, well worth $20! And lastly, I’m apparently blind because my LJ500 DOES indeed have...

    JLG LJ500 Little John stand-on mini skid steer

    Small update: The tank is pretty well trashed. There's so much junk in it that I'm going to have to either coat it or keep constantly shaking nuts and bolts around in it with some thinner to get all the crap loosened up. I'll continue that route for now, but once I get the carb back from my...

    JLG LJ500 Little John stand-on mini skid steer

    So, I pulled the carb off today, when I removed the bowl I found this: So I figured it needs a gasket, a washer for the bolt, and since it’s so dirty in there, I checked the tiny bowl filter/screen on the petcock. Wow. PLUGGED! This is what came out! So, pulled the tank. Yep, that’ll be...

    My thoughts exactly! Definitely going to peel the decals off. I’ll try to preserve them as best I can. Should be welded from both sides for sure, wasn’t really thinking earlier. I’ll drill out the ends of the cracks, burn them in hot from both sides, then grind smooth and probably fishplate just...

    JLG LJ500 Little John stand-on mini skid steer

    A few pics of the cracks at the upper cylinder mount at the back of the machine. Looks like it goes under the information tag. I'll have to peel 'em off and check, or lift the loader arm all the way up, block it (set it on my retaining wall?) and see if I can weld it up from the back side. Not...

    JLG LJ500 Little John stand-on mini skid steer

    I recently acquired this little guy, haven't gotten a chance to work on it yet but figured I'd make a thread about it. Shouldn't need *too* much tinkering to get it going. I know it ran last year, and I did get it to "pop", albeit for just a few seconds. I'll post updates as I find time to mess...
