Great info. I’m in the market for a mini and this video helps me understand some of the wear items I should look at on a used machine. Camarata has track replacement down to a low effort art. He uses the machine for 95% of the effort.
Thanks for the comment! I watch Andrew's channel as well, good stuff. Check out my new track install video, I've learned a few lessons lol. ruclips.net/video/JJr77EuR13k/видео.html
The Kubota WS manual specifies 30w motor oil is added to the rollers through that allan wrench plug. 80cc's for the KX040 rollers. The carrier roller assembly doesn't specify adding oil, but under fluid capacities, it shows that it takes the same 30w motor oil.
Hey Steve I appreciate the comment! It prompted me to go back through my WSM for the KX71-3. It states similar information. SAE30w oil. The front idler gets 75cc. The bottom track rollers get 80cc and the top carrier roller gets 60cc. I think most of the ones i replaced were too-far-gone for new oil, but i might check that on my front idlers and see if i can get them to quiet down! Thanks again!
Nice! I think someone mentioned previously you might be able to just loosen the track and pry it down far enough to change out a roller instead of removing the entire track. But make sure to check you top while you're at it! I couldn't believe how toast mine were!
Hi Neal i just watched your video ,i would suggest that you let all the grease out of the front idler ram to make it to remove and replace the track , as it looked like the idler could have went back further into the track frame i normally put the back of the bucket against the track and push the idler in , as for the noise your front idler may have a piece of rock jammed between the idler and the idler frame as this happens to my 5.5 tonne kubota when you had the track off you can remove the idler and frame just by pulling the idler forward with your hands and then you can check for rocks caught or if you leave it and it is a rock it will wear down and drop out and the noise will stop hope this helps
Hey thanks for the tips Bill! I actually just ordered new tracks, so i should be putting them on in the next week or so. I'll be sure to make a new video with all the advice i have received and hopefully it goes much quicker!
"Let me show you what the trick was". Uses two crowbars and a sledgehammer for 20 minutes... :D I'm a new owner of my first excavator. I predict similar learning experiences in my near future. ;)
Hey Travis i just saw this comment! I would say if rollers are not spinning, that would really make the tracks not want to spin. But it could also be your drive motor. I would lift the tracks off the ground and try to spin them without weight on them and see if the motor is having issues spinning by itself. When its in the air you can probably check most all of your rollers as well.
Glad to hear this video helped you! I have another video putting new tracks on this machine where i used a tractor to assist and it went much faster! But yes as far as the roller and idler replacements, not a tough job. Thanks for the comment and make sure to subscribe for more DIY equipment videos!
Thanks for the comment! Glad I could help! I have a newer video of putting new tracks on this machine with my tractor assisting. It was much easier! Check it out on my channel
Thankfully my sprockets are still in good shape! It appears those are fairly easy to replace by removing some bolts holding the sprocket to the final drive.
Cool video man. So little videos about diggers. Wish someone would do full repair videos on these too. I got a Kobelco and love doing things myself but scary when bugger all info
Thank you Chase. I agree there isn't a lot of information on these. I replaced the head on this machine's engine last year as well, i wish i had gotten some video of that. I ended up purchasing an electronic version of the factory service manual and it makes the projects a lot easier to tackle.
You can replace just the bearings TIMKEN 6206-2RS in the upper rollers at a fraction of the price of a new roller...The bearings cost about 10 bucks each. Total repair cost 25 bucks at most.
Hey thanks for the note on that! I'll write it down in my service manual. The left side top roller shown at 3:47 was pretty much roasted, but bearing replacement may have been an option on the right side.
Thanks for showing us these things it helps me understand the workings of my mini digger ,just a point why not weld a flat bit of plate on that top roller pinch boly just a strip of 3\4 by 1\8 strip .wouldn't be difficult if you can weld ,hell pay my air fare from UK and will come do it for you lol ,take care great work. Ive subd.
Thanks for the comment and sub! I did weld a piece of plate for the roller pinch bolt area. You can see it around 11:58 in the video. I think that's what you were referring to.
I realize it’s a bit more money, but if half or more of my rollers were bad, I think I would replace all of them at once. Seems like they reached their lifespan. I hate waiting for the next one to break. Now if money is tight of course only fix what you must. On test drive after repair, it definitely sounded as if you had at least one more bad roller. I think you can replace the rollers without completely removing the track. Just loosen it.
Hey thanks for the good advice! Buying the machine used, i wasn't sure if any rollers were already replaced prior. I think this year it might be getting new tracks so i'll get another chance to inspect!
Thx professor, really enjoyed the class today, what do you use this for, I'm looking for one for my farm, do you feel it has enough power to take down some trees, I need to build a road around my property, not sure what size and what horsepower I need, Ty, God Bless you and yours.
I use it for grading with the smooth bucket and digging trenches mostly. Subscribe to my channel and check out my other videos to see the machine in action! I've taken down some trees, but I really don't like digging stumps with it. Its a good size for me because it does not damage lawns much and its light enough I can haul it with my skid steer on the trailer at the same time. I have been keeping my eyes out for a good deal on a KX121-3 or a KX040. That's the largest machine Kubota makes that has my same quick coupler so all my buckets would still fit. Otherwise you could bump up to the U55, KX057, or KX161.
Does your grease gun and you impact driver use the same battery? What voltage is you impact driver? I need to get one for working on my machine. I have the grease gun already.
I was using older dewalt 18v nicd tools. I have since switched to makita 18v lithium. I am still using my dewalt 18v grease gun with an adapter that converts it to use my new makita batteries. The 3/8 impact is a great tool I use it on almost every project. It's compact and fits a lot of places and so much faster than a ratchet. Thanks for the comment!
Excellent video you got right to the repairs no bullshit no promoting the channel. Not many kx71 repair videos on you tube. Just curious how many hours you had on your machine when you made these repairs? I rent out 2 of these machines and work on them myself. Thank you for making this.
Thanks for viewing! It had about 2700 when I did the video. Probably around 2800 now. It is a 2007 machine I believe. Runs good but I’d like to have a kx040 now. Subscribe to my channel I plan to post some more videos on this machine!
No. I’m assuming it’s the large front idlers. Mainly the left side. But it’s hasn’t been bad enough to bother me anymore. I have pushed and pulled on the idlers and they aren’t loose or wobbly but I’m guessing the bearings don’t have much life left. Those replacements are about $350 each.
Has anyone had experience trying to “patch” a track that’s torn to the center of the track but not thru the other side? I am just trying to limp thru my homesite and need another 100 hours out of it to be finally done. My other track is in decent condition and replacing one track seems kinda ….eh?
I maybe with steel straps and bolts like a conveyor belt is mended together. But I would just try to find used tracks off another machine. People usually try to get rid of them because they're so expensive to take to the landfill. I sold my old set for $100 or so if I recall
You worked WAY too hard to put that track back on. Get yourself a cheater bar (3 or 4 foot piece of 2" metal pipe). Lift machine, (with tensioner retracted) and get track on the sprocket end. Get the front mostly lined up with the idler. Insert the cheater behind the idler, lift up on the pipe and slowly run the track forward with the control as you lift with the cheater. It'll drop onto your idler easily. Properly tension your track running it both directions while you have it in the air. You don't need to "horse" the track at all this way and it lines itself up naturally as it's supposed to be. I'm nearly 66, have been in excavating all my life, and have a bad back. It takes me under 10 minutes to handle a track in the field alone.
The Spook thanks for the advice. I’ll try that next time I have the tracks off and report back. I think it could have gone much smoother with two people! One person to run track while I use a crowbar.
Tony, no the rollers did not have grease fittings. I show the details of the new Prowler rollers around 8:05 in the video. They are sealed and there is a small allen head oil plug.
I just recently had my metal track broke , due to no been able to find the part . I had to replace with rubber tracks . Everything fits fine but seems like the rollers need to be change ,I wonder if these would work in a komatsu PC50UU . The track is 16" wide . Any info is highly appreciated.
@@NealORussa That excavator has to have a lot more hours than that with that much wear on the rollers. That hour meter was either replaced before you got the excavator or they forgot to put oil in the rollers at the factory.
Kirk Palmer yea it was 2700. Also the previous owner did concrete demo with it and probably saw a lot of pavement. I can tell he also never used a breaker, just bashed with the bucket and teeth. I’ve rebuilt every cylinder on it. Boom cylinder was bent.
Machine has been working great though. I do light commercial and residential grading and drainage and it’s been reliable for me. Also now I have a hydraulic thumb, quick coupler and 3 buckets that have really allowed me to do a lot more work.
Does anyone even look over their machine before they run it? Surely missing a roller is pretty obvious... oh wait no one ever cleans their machine either so you cannot see a thing..
I know what you mean Wes! I actually acquired the machine in this condition and being new to equipment I was not aware of the issue when I made the purchase. Live and learn!
Thanks for making this man. You did a great job filming and showing the problems you could run into and also how to fix them.

While you have the track off, check the drive sprocket spokes for wear. When the teeth get thin or sharp, time to replace. $100-$160 per sprocket.
Thankfully my sprockets are still in good shape! It appears those are fairly easy to replace by removing some bolts holding the sprocket to the final drive.
