Excavator Repair. Let’s Fix This Sloppy Hoe! Yanmar Vio-50.

This was a pretty involved fix, more than I was expecting when I started on it. Isn't that always the case? I got it done though, and also fixed several other problems like the thumb, side cutter, and grease zerks.

We had a similar rock that kept destroying lawn mower blades in our side yard back in the 70s. Father decided one weekend to get rid of it. Turned out it was 5 ft in diameter. We reduced that sucker to rubble with a manual star drill and a sledge hammer (free kid labor). As soon as you pointed to the top of that one I knew the story.

@@buildingsalvage Continents, and price range. I love CEE (and Homie), as do we all, as we rightly should. But to CEE, KZbin is secondary, they're a business, remember the workshop he has that we wish FarmCraft had? CEE caters to a very very boutique and heavily government subsidized market + there's a material shortage (so costs even more). The time CEE would have spent lineboring, welding, lineboring, freeze-fit, on the pin ears for this Yanmar Stick, for the money it is that you THINK they should be doing it for, he could have spent the same time and effort doing the same exact thing for 5-10 times more because that's how much their customers are willing to pay. CEE and FarmCraft could have practically been neighbors and it wouldn't have made any difference unless they were friends doing favors to one another. Not to put CEE or FarmCraft (who did an excellent repair btw) in negative light or anything of course, and if CEE wants to correct me on anything that I've said, they're free to do just that.

Just as an important note, that quick attach housing is loose because the pin is supposed to be statinary. It is supposed to turn with the pin. There are no bushings in there for a reason. Your pin is supposed to have a hole drilled in it to hold a split pin. That is why one of the bosses had a hole in the casting. If you leave it like that it will wear out again, grease or not. The only part of the pin supposed to move is the bushings in the stick and the thumb.

[@avid6186]

The first side he bored on the mill had a hole which should have had a pin though it and a matching hole (missing?) in the main pin to stop it rotating. The rear pin had an "ear" and a bolt holding the pin in and stopping it turning which will be why it wasn't as worn.

nice work, just for future reference, you can use your lathe as an impromptu line bore, as long as your bed travel is at least double the width of the part, you need to make a solid bar that you can run between centers with cutters added through the bar in 1 or more locations. takes a bit to set up but once used to it you will get perfect bore alignment every time.

If you only knew how many times I was able to say, "That's what she said." during this video. Haha! Hey great video you are a great machinist. Here's a little tip for you next time you are trying to fit a sleeve into a collar. Putting the sleeve into the freezer that was fine, that's what you should do. However when heating the collar, go to the area on the edge where the collar is thinnest and just heat the metal there. Maybe like an inch wide section with a finer Torch flame. It will actually open the hole more as it is only expanding the metal at that section which pushes outward, almost like putting a hydraulic jack in the opening of a "C". When you heat all the metal all the way around it expands inward also.

[@daverose4789]

great work done there and a fantastic improvement in the bucket. One method you could have used to get the alignment of the second hole is to use a dti to 'clock' the already machined lower hole. You'd need to mount a long shaft say 3/4" diameter in the mill spindle and attach a dti to the bottom end of it just above the lower hole. Adjust the table position to zero the dti and the mill spindle is exactly on the lower hole. Refit the boring head in the spindle again and the second hole will be bang on center to the first. Keep up the good work . Looking forward to the next installment.

[@terencem9962]

That's exactly what i was thinking about in me head! KZbin is so great to see other machinists work and then to see comments from machinists about said work. Much can be learned :)

[@DamLins45594]

I was thinking the same thing as I watched this. Not sure if he has a DRO on his mill, which may have helped him get close enough to use the DTI to zero in on the bottom hole, assuring alignment of the yet to be bored upper one.

You need to get yourself a set of feather and wedges. You just drill a line of holes a few inches apart, insert the wedges, then hit them in sequence. The rock will crack off pretty much in line with your holes. You could have dug a foot or so down and popped the top right off that rock.

When removing those two small pins for the small quick release cylinder, instead of hammering away at it use long bolt like you did, but let it do the work for you by putting a socket that's bigger than the hole you're pulling from and a nut to back the socket. Hold the bold and tighten the nut. It'll pull the pin right out regardless if it's held by setscrews.

But it worked for me.

[@nathancook5354]

Any excavator I've run that was new enough for foot pedals has them come far enough back so you can step down on them to reverse. I'd guess that the actual pedals are missing and what you have there is just the bracket that the rubber or plastic was supposed to attach to. Still better than my old CAT E70 that you just have to angle your foot against the lever though. Well done on the bushings there, that would have been an expensive replacement or even repair from a machine shop.

[@kd2eat]

I was thinking something similar. Does something fit over those foot petals that allows you to place your entire foot down and tilt forward and back.

I also have a Yanmar, albeit smaller, a Vio17, and it is the same thing. The pedals are absolutely garbage and the angles are not ergonomic at all.

[@avid6186]

Awesome job, that will keep it going a lot longer. Couple of minor points. No grease fitting required as the pin isn't supposed to move in the quick hitch. The first side you bored has a hole, looks like about 8mm through it, there should have been a matching hole in the main pin and a bolt through it to stop it turning. Of course grease will do the job as well. The second point is just a suggestion or a "I would have done it this way". When you discovered the 2 holes weren't quite lined up polishing a little out of the appropriate sides of the tightest bush with a die grinder or even a drill and flap wheel would allow the tin to tilt the fraction needed to line up. A very small adjustment to the hole allows the end of the pin to move much more. Possible to end up with a tighter fit that way? There are many ways of skinning cats, that's just what I would probably do. Thank you for posting, I was looking for inspiration, I need to do the bushes in the end of the dipper arm on my one and a new pin of course. Hopefully it should be less involved than yours ended up 😀 Hope it's going well for you.

In my opinion, the quick coupler hole was worn becouse an incorrect fitting. The pin should stay stationary with the coupler, you can see that from the fact that the coupler had holes for insert a bolt to stop the rotation of the pin. When they installed the finger has removed that feature and now the pin stay stationary with the stick arm and wear the bore. Recentrly, Dirt perfect has installed a new thumb to his new hyundai and he welded a piece to the coupler and the pin has ear to engage in it to avoid that problem.

[@joelcurcio1403]

Just so you know the reason those holes egged out is because the thumb is after market and was not installed quite correctly. From the factory the pin was designed to be fixed to the coupler and rotate in the stick. When the thumb was installed the pin now rotates in the coupler and stick and is fixed to the thumb. There are a couple ways to fix that. Ideally the thumb should have grease zercs and bushings and the pin should have stayed fixed to the coupler. Love your videos by the way.

I thought the .002 interference fit was too much but was impressed with how you did it. After you bored the first hole I would have made a fixture with just a round plug screwed it down through the center of it to the mill bed and then indicated my spindle to it. Then used that to locate the center for the other bushing hole. Also I would not have drilled the zerk fitting holes where you did because of weaking that part. I would have drilled the pin and put the zerk fitting in the end and had a hole come out into the middle of each bushing for grease.

[@mrxmry3264]

8:43 my thoughts exactly. yeah, i know what a line borer is. cutting edge engineering in australia uses one. 24:14 yep, that's the one i was talking about! 37:05 you're doing it wrong. in my job training i was told to hold the bolt and turn the nut. 40:52 more challenging than you thought? that rock puts up quite a fight. 42:18 man, that thing is STUBBORN. it just REFUSES to give up. if that rock is still a problem next winter, drill some holes into the top, fill them with water and let it freeze. no rock can withstand that kind of stress. repeat as necessary.

[@d6joe]

I am surprised you dint do new bushings for the bucket pivot in the excavator stick when you had it apart. The repair was a Huge improvement!

[@eformance]

Most mini excavators have a galley in the pin and you grease the whole shebang with the hole in the pin, so they didn't install grease zerks in the moving part. Also, before you welded it up, there were holes for a retaining pin through the bore on the outside, these are to hold the pin in place so the pin rotates in the stick, not the bucket end. Your setup was probably altered when they put the thumb on there and the pin is no longer fixed to the bucket end, so it wore. That's why there were no bushings in the bucket end to begin with, it was designed to be static with relation to the pin.

[@stephenlehr6020]

That was exactly what I was thinking, the rear pin of the coupler as a locking bolt that keeps the pin from rotating in the coupler, so all the rotation is between the pin and rear linkage. The original pin for that coupler was likely similar so no rotation happened between the coupler and pin (no need for grease or zerks then), just the end of the stick and pin. The longer pin for the thumb changed that and the coupler was not designed with replaceable bushings like in the end of the stick, so the cast coupler wore easily against the hardened pin. Hopefully the "new" bushings in the coupler will "wear" better with the grease zerks added. Probably would have been a good idea to machine a shallow grove inside those "bushings" in the coupler that aligned with the new grease zerks to make sure grease gets ALL the way around the pin (not just mostly on one side....) That is the most wearing joint on the whole machine.... Just keep that pin REALLY well greased!! All that said, great job on the repair!! On the foot pedals, just weld some extensions on the rear portion of those pedals that are horizontal (parallel to the floor), so that the heel of your foot can rest on them and push down for reverse. On many machines they are hinged so you can flip them up to lay on the portion of the pedal you already have, so they don't take up extra floor space. But if you are going to use them, they do really need to be flipped up "out-of-the-way"....

[@michaelpetersen9656]

Grinders and paint make me the welder I ain't ;-). Great video bud. Keep up the good work.

[@davidmiller2719]

The last mini excavator that I rented had a pivot point for foot operation. You may be able to simulate this by adding a leverage point on the bottom of the foot placement like the top one. This would possibly allow your heel to naturally pull back without hooking your toes.

[@edstimator1]

Wedges work fantastic. Couple of hours and you can bust that volkswagon into manageable pieces. Once you’ve done it, you will never be intimidated by a boulder again.

[@chrissmith7655]

Hi, to get out the two smaller pins, remove snap rings and set screws, pump grease into Zerk ,grease comes out of the small hole at the bottom of the pin through small hole pushing out the pin.

[@toddrife8375]

You did a damn fine job, and you had to do it the hard way. For the big rock in the field you should drill and use wedges and feathers to split the rock. Keep up the good work. ✌️❤️🍺

[@Mhakeman]

Totally getting better and better with all the videos- really digging this channel :) keep up the great work, one of my favorite channels!

[@alsaku33]

It is so nice to have hydraulic quick change...when it works...😁 Love your channel sir!

[@Ariokanikan]

That was an incredible amount of skill and effort that went into fixing the bucket slop. I was not expecting such an in depth repair. I would've had to just try to find a new part or go to a great machine shop.

[@Takman74]

For rock breaking all you needed to add to your drilling set up is some feathers and wedges. Commonly available! They work like a charm for breaking stones.

[@morganblu]

Curtis is an amazing machinist!

[@alanm3438]

Good job on the video and the repair. I know that it took a lot of time but it was worth your efforts. You did the best that you could with what you had. I think that the rock is so hard that even if you had a jackhammer on the excavator, it would not brake. It sure is something how rocks grow when you go to dig them up. It is interesting to see your talents in motion.

[@TravisMontesano]

I like this style of content. You are a man of many talents, thank you for sharing your skills with us. I have been watching cutting edge machine for a couple years now and that guy has some amazing equipment to work with. I hope you get that machine all sorted out its japanese so it should last a lifetime. Have a good weekend!

[@1960jelliott]

New to your channel: great topics and thoroughly sharing your reasoning. Folks that are willing to make parts to make things work are the life-blood of this, and every other country - GOOD ON YOU! I, too, have never had a line-boring rig, although I've seen some pretty impressive field machining operations. I don't suppose you could've fixtured to the saddle on that little 12" lathe. One thing I'd offer for consideration, though: after boring the 1st side of the yoke, make a temp. bushing (good-n-snug, and all in one setup) to center up on a known straight piece of drill rod, say some 1", or such. Then you can flip the unit, insert this temp. "transfer rod", and indicate to it, both axially and radially. Keep the rod in the back of your rollaway for future projects. Again, wonderful work on the videos!!

[@FishFind3000]

6:15 It more likely could be a BSPT 1/8” -27 thread. That’s what my Kawasaki small engine seems to be. NPT and BSTP are nearly identical with small differences. But they might have used a standard 1/8” not for easy replacements since the grease fittings might get damaged.

[@TheHomePros6221]

Yes it is British standard pipe thread

[@odiesclips7621]

I'm catching up on your older vids. There was a familiar similarity to your voice that haunted me until I finally got it. You are the doppelganger for Walter White of Breaking Bad. This was a great clip!!

[@holzmann8443]

Your vids are getting fantastic. It's great to watch your repair triumphs in a world prone to quick disposal and replacement. Keep up the fine work!

[@volps2588]

Liked and subscribed I'm new here, and just came across your videos. I have a 2.5 ton Kobelco mini escavator that I bought at an auction too which looked tired and neglected. After some TLC and a good clean and paint job, it came up like new. 3 Cyl Yanmah motor running but had blow-by and was overheating and had to be rebuilt, now It's a great little machine for my farm. Keep up the great videos I'm hooked

[@schmatzek1]

Hi, i am from Germany. Nice Work. I have a Yanmar B37V the complete diesel tank was rusty inside. all filters were always clogged. Last week I cut out the tank and I built a new tank out of 1.4571 stainless steel in the same size like the Original. it was a lot of work but it was worth it. I keep my fingers crossed for you in the future. P.S. Kurtis from CEE is Great! 👌

[@jasongarland3165]

The big rock at the end.....I was almost expecting you to drill a hole in it, pour something it, cap it with a fuse and run! 😜

[@hotflashfoto]

I know this is too late for this repair, but I thought of a way to get that pin centered in the oblong holes. 1. Repair one side with a new bushing, then insert the pin so it sticks out of the second side just a little. 2. Drop the new bushing onto the pin, then mark where it goes. 3. Machine the oblong second hole so you can insert the bushing. It should be lined up quite nicely, even if it's off a tad. But it should be pretty close to dead on. I like your videos because they show me things that interest me, and which I have never or hardly ever attempted. Thank you for sharing! After having watched a number of your videos, I'm subbing on this one.

[@tompiper3]

Years ago we had a boulder in the field that made that one look like a pebble. Had a D9 to push it out of the hole. Most larger rocks like that with an excavator that's size, we would dig a deeper hole next to it and roll the rock into it.

[@Fornaxfornax1]

When welding a heavy piece like that(repairing the cracked component) what you can do is use three or more runs instead of one huge weld. This means a smaller heat affected zone (because subsequent welds anneal the previous ones). This results is less hardening and a weld that is less likely to crack. I might have ground out a bigger weld prep and then used three small runs. Its a small thing but the previous welds did crack, so it is a point of stress. Your welds will probably hold, but next time - for the sake of 5 minutes extra work...

[@wolfpreist]

I've watched this quite a few times (I watch videos when they release, and when i need white noise while i'm busy doing other things i'll put on my favorites while i work), and i just thought of a way you could have gotten it a bit closer, but it would have been a lot of work and i dont know it would have been any better. After you bored the first side, you could have turned down a bushing to fit the pin and the new hole, maybe make the bushing out of something like delrin plastic for temporary(seeing as how you did an interference fit on the actual bushing), inserted the bushing and pin, found center on the pin, marked that on your DRO, flip the part, put the pin back in, and align the pin so the center lines up with what you set on your DRO for the other side. Not sure if that would have gotten you any closer or not.

[@DMHRC]

You're doing great with the old Yanmar. One of my best homemade tools is a pair of vice grips with a nut welded on top. I thread a small slide hammer into the nut and pop loose anything I can get the grips on. Works great on oddball projects like this and very simple. I even use it for stubborn cotter pins. Might be something you can use.

[@donanything6816]

Another great video. You had me rolling a few times. Nice bushing creation for the repair excellent use of the mill. I'd have been at best trying to use the mag drill at worst filling and grinding. New subscriber, enjoying your content. Thanks

[@jongerber3476]

Good video. I have turned a boss on a flat plate then swung that to reference alignment. Just my 2 cents. Not being a know it all by any means. Thanks for sharing. Have a good one.

[@edgewood99]

quite the massive erratic rock. Dang. Thanks GLACIER!

[@MrPatrick1968]

Great video man,,I surprised a man of your skill did not make a set of feathers and wedges to split that stone,,great endurance test for you well done

[@Slider68]

I used to dig out big, annoying rocks but recently I've realized it is much easier to just dig a big hole beside the rock and roll it into it. This technique works well for me and one big benefit is I typically don't need to reposition my backhoe...

[@unemax]

Admiring your excellent workmanship. 👏🏻👏🏻(Sweden)

[@DanelonNicolas]

is this cutting edge engineering or the farm craft 101? hahaha 😂 I love this playlist

[@DanelonNicolas]

lol I leave the comment before the CEE reference haha

[@danielyoder5928]

The struggle with machining large parts on smaller equipment can be frustrating, but you won!. Good job. The only part of the repair that should have been done differently was the crack repair on the thumb, it should have been a full penetration(sp) weld. Since the crack still exists there will be a stress point there, which in time will allow the crack to perpetuate through the rest of the metal towards the weakest point. Other then that, a good repair.

[@stevem6711]

still mad skills with the lathe. Great job! As far as the foot peddles, it looks like you are missing pieces for those. My Kubota has longer peddles that you can push down with your heels to move in reverse.

[@candynevadacinnamon5527]

@13:48 For future reference, you could have made a 1" to 2" thick plug/disc that will slip into the first hole you bored. Put a hole into the center of the plug (or anywhere really) so that you can bolt the plug to the table. Indicate the center of the plug. Slide your piece over the plug. You should now be able to bore out the opposite side in line with the first hole. You could also add additional threaded holes to the plug so that you can clamp the piece to plug. Thanks for the video!

[@josephkrug8579]

The video I watched right before this was a line boring video that Kurtis did on CEE :) I really enjoy your videos and one day hope to have more than a in-city condo to be able to have big toys and room to play with them myself.
