Installing new bushings and pins on my miniexcavator

Last part of making the Kubota great again, now we are installing new bushings and bolts with my homemade tool and getting it ready for work.
Part 1 welding the stick:
• Making the kubota grea...
Part 2 removing bolts and bushings:
• Changing out all pins ...

Looks like the business is going well - building a nice fleet of equipment and the shop is filling up.

[@MiniMachines1]

Yes we had some time now for maintenance, but In a week I how we can start excavation for full this season. But right now it's snowing so...

[@TheDavidarlen]

Nice job, I enjoy watching you repair your excavator

[@arnoldromppai5395]

to get the old bushing out, weld a bead around the in side with 7018 stick rod, a little tap an they fall out, put the new bushings in the freezer over night an the slide nicely in with a fine thread rod.. by the way they are not blots, they are pins..

[@MiniMachines1]

Yes I've done that before, but here this was quicker. But it's A nice trick welding. Yes pins are more correct, thanks didn't think of it 😊

[@carjacker0]

a bit late now but i would have cut one of the old bushings down and used as a spacer at the end of the dipper rather than weld in the bore ,other wise a good job all round.

[@MiniMachines1]

I tried that the last time but it got really hard to get greas in since it comes out in the middle of the bolt. And also it's wider in the middle ☺️

[@jimwesselman]

Looks great and many more years of work. Heinrich did a great job of painting it. Sure costs alot less to refurbish it then a new one. There is a product made by Loctite, I believe it is a bearing retainer but I have seen it used to fill in the gap between a bearing in case your bushing wants to move on you again! Have a great spring and hopefully you have some interesting work to share with us.

[@MiniMachines1]

Yes it turned out looking like new😀 Yes I've think I heard of it, will keep an extra eye on those in the front so I can catch it early if somethings moves.

[@kidhenderson8260]

Wow...you been busy. Things look great!!!! I always try to keep my equipment looking good.

[@MiniMachines1]

Yes luckily I got Per Erik that works full time with me, so we are two doing maintenance, and he plows snow so I get time to do maintenance instead 😊 Yes I think it's important to keep the machines looking nice, specially when I rent them out, if it looks good the people renting is also taking better care of it.

[@kidhenderson8260]

Agree...awesome.

[@douglasthompson2740]

For high torque operations or a tool that will be used several times I use grade eight steel all thread rod with grade eight nuts. Not only is the steel stronger but the thread cut is around eighty percent or better while the galvanized rod is more expensive, made of grade five steel and because it is going to be hot dipped galvanized (or even the plated variety) its thread tolerance is in the sixty percent range to allow the coating. The hot dipping process also weakens the already weak steel as well. Great for outside work in contact with the weather but not so good for stressful applications such as your puller. These ratings are SAE but the same applies for metric fasteners.

[@odin-eliottodinson7330]

@Douglas Thompson Technically I would agree with you. Though I think his choice of all-thread might have been based purely what was readily avaliable. Don't forget that these videos are made in The Worlds Northernmost Town, and sometimes you just use whatever you have in stock to avoid breaking your wallet. :-) As a sidenote, if anyone wonders about the Metric/SAE ratings: Metric 4.6 is approx "Grade 2" for bolts, and "Grade A Nuts" for nuts. Metric 8.8 is approx "Grade 5" for bolts, and "Grade B Nuts" for nuts. Metric 10.9 is approx "Grade 8" for bolts, and of course "Grade G Nuts" for nuts. (not "Grade C Nuts", those are for "ASTM A325"...) Metric 12.9 are not graded in SAE, but I would suggest "Grade 99" and "Grade Z Nuts".

@@odin-eliottodinson7330 Good info. I fully understand the use what you got way. I live on an island with no roads in SE Alaska pop. 10K.

[@MiniMachines1]

As Odin say it's not in stock up here, but this time I just used what I had in the shop 😊

[@BertPle]

Can you put the new bushings in the fridge to cool them? Then they will shrink a little.

[@aivarg472]

good job again! must feel so good to get all your ready for the summer! hope lots of good work comed your way!

[@MiniMachines1]

Yes it's great to know that everything is serviced before summer comes, avd we have a good amount of work already booked so that is great.

[@Dashu89]

Great Job and thanks for the Video. But one question: from where you have bought the bushings? I'm searching it for my Kubota U10-3 SL here in germany but do not find it really. Thank you

[@formdog9861]

nice job new sticker will make big improvment

[@soulis1000]

Great work, turned out exelent!

[@MiniMachines1]

Thanks 😀

[@bigbenjit]

Thanks for sharing this. It's been great to watch your business grow with the channel and I admire that you are investing down time into improving the condition of your equipment. This old unit looks new again and no one will know otherwise. I'm constantly reminded on how people that weren't your competition forced you to quit your job and build your side business into a full time business. I'm sure they are regretting it as you become real competition. Keep grinding and keep thinking big!

[@MiniMachines1]

Thanks for watching 😀 Yes I always done maintenance in the of season, it's so nice to know that everything is ready for excavation season, that starts next Monday for us, if we don't get 50cm of snow this week 😏 Yes we are getting a bigger cut of the cake now that I do this full time, and so far it looks like I made an good choice, business is looking good 😊

[@hollandduck79]

from the Netherlands thanks for the video

[@MiniMachines1]

Hi thanks for watching 😀

[@geraintjones495]

Nice work looks good, have you seen the expander pins they save you on line boring, it would work ideal as a boom base pin where you had small amount of play. I bought one for my Hitachi and its done 1000 hours with expander pin and its still tight. Thanks for the videos

[@MiniMachines1]

Thanks😀 Yes I've been looking at them, that say it last longer than the original ones so should be good. I will for sure test them when I get a chance😊

[@cd1168]

Can you point out those extender pins ?

[@LoneWolf-wz9hj]

Great idea using the threaded rod and washers to install the bushings. The Kubota turned out really nice, looks new again. Is that a Honda engine in the mini dumper?

[@MiniMachines1]

Yes I used the same for installing new cylinder bushings in my old massey ferguson. Yes or an honda copy engine, cost like $300 for a new engine compared to $1200 for an Honda

[@AndrewMarsch]

Picking up a k008-3 next week. I do trenching here in Canada and am hoping this will be a good addition for smaller/shorter trenches. Great videos. I see in your thumbnail you have larger machines as well as the u10. What kind of jobs do you find yourself grabbing the small machine? Thank you!

[@MiniMachines1]

Hi and congrats on your new machine, the kubota won't let you down. Here the kubota is mostly rented out to private. We use it mainly where we can't get in with the bigger machines, we operate in a small town that is really narrow and little room between houses. Is also great for smaller jobs where we can go in with a much smaller disturbance of the yard. We also use it for going inside houses to digging out basements with it that's somthing it's perfect for. You will see a lot of videos on my channel of work being done with the little kubota 😊

[@dona6891]

I am no professional, but shouldn't you have put your socket closer to the last bushing you were pushing in. Looked like there was alot of strain on the ear that was not being bushed. I guess I would have been a little more cautious. Thanks for the video. Warren in Vermont.

[@nitramhitms1835]

It's easier to just put the bushes in the freezer over night and then they just side right in place

[@DieselRamcharger]

excellent video. i had planned to make this same tool but was unsure if it would work or not. Now i feel better with the task :)

[@MiniMachines1]

Thanks 😊 works great I've used it on cylinder inserts for engines also 😊

[@irwinmccook7942]

excellent job!! well done!!

Hi Mr Mini Machine. Great video. Still very instructive. By chance, any costumer that upgraded their manual quick bucket connector to a hydraulic one and like to sell it? Please let me know. Thanks.

[@dstevenpaisley]

That rock Hammer will distroy a set of bushings fast .Hard on a machine

[@MiniMachines1]

Yes that's why I charge extra for using the breaker 😀

Are your engine mounts ok? the engine seemed to move a lot. Nice job!

Which Model Milwaukee is your Impact Gun please ????- looks a great handy tool !!

[@petergdk]

Great video series. You have made me want to buy the small Kubota even more. I live in Sweden, and want to buy a Kubota 10-3, but i would like to transport it in a regular van, and not a trailer, since it would be way cheaper to transport - especially when going on bridges a ferry's, and could be done without having to get a trailer license for heavy trailers. Do you think it would be possible to transport it in a let's say regular VW transport T4?

[@MiniMachines1]

Thanks. I have transported it in a sprinter once, would probably fit in a T4, for sure if you get a pickup T4

[@robertrobinson6785]

Or just freeze the bushings.why complicate it..

[@hvy1ton]

The loose bushings are going to rotate in the bore. Metal on metal wear will only get worse as the bore gets looser. Needs to be line bored back to spec.

[@MiniMachines1]

Yes you're probably correct, but not this round 😬 hope it holds a bit more 😊

[@Erman456]

Very good 👏👏👏👏💯💯💯💯

[@richardjacques6370]

Nice video. I am new to your channel. Good stuff from Canada

[@MiniMachines1]

Hi thanks, and welcome😀

[@hub-p4g]

Hi, strange question.. could you give me a idea how much the boom weighs please? i purchased a used boom and dipper arm from a Takeuchi 216 for a project but have no fork lift to get it off the truck when it gets delivered, hopefully i can move it by hand to a pallet on the back of my tractor but can't find the weight of a boom from any small machine online.

[@MiniMachines1]

Hi i think that's no problem to move by hand. The one for my little Kubota i could lift by hand so i guess dragging yours should be doable

[@hub-p4g]

@@MiniMachines1 Thanks for that, hopefully the driver is a helpful type..or it arrives on a tail lift.

Use some type of pliers to hold that bar like vise grips so you don’t smash your fingers I’ve done this to many times myself before learning this it hurts me just to watch

Where do you buy original parts in sweden? They are impossible to find in Denmark and i travel to sweden 5-6 times every year. Its also time for my bushings and pins right now.
