Bobcat S-150 Loader arm repairs

Hey guys, Here is a rather quick video of whats needed to repair your Bobcat Skidsteer loader arms if the tapered pins are not keeping tight.
This takes a little cutting, a little measuring and a little machining. Hope you enjoy. Kick back and have a great weekend. Thanks for the support.

You can tell how much experience a guy has by the size of his umbrella. I enjoyed watching as always.

[@beyondmiddleagedman7240]

You can use a center punch to out line your circle with a series of punches. Won't disappear from the torch. I do this when blacksmithing.

[@JohnRaySalazar]

Wow! Never thought of this!!!!You’re a freaking genius bro! Thanks for sharing!

[@ypaulbrown]

I was going to suggest that......good information....

[@clintcowles7563]

I was going to tell him the same but I decided to check a few comments first to see if any other has or had...great advice !

[@Hugh1966]

Beyond middle age man , I like your method .

[@theessexhunter1305]

I have a steam valve from a wreck around 1870, it has dot punch marks where they laid out the pcd For that job I would have used a mag drill and large core bit to get the clearance with a clean cut. I use 9" slitting discs on a lot of jobs these days as a clean cut and no torch gouges. Can't use it all the time but not grinding to get a clean face. Each to their own.

[@carlinlentz6849]

You seem to be very patient with your son. I can tell he has great respect for you. You were clearly a good father and your wife was clearly a good mother. That isn't easy when you own your own business. Also wanted to say I love your videos ❤

[@freedthebeast4973]

Yeah. That time when he was punching de slag off and his father tell him to be careful to not burn himself. If he was like my father or grandfather they would let me burn my hand pretty bad and then remember me to use protective gloves haha

[@ronbuckner8179]

Gloves son? You’ll learn the hard way with scars.

[@htownblue11]

Sometimes retrofitting a wearable item into an already roached out piece of equipment is much harder than working on newer equipment. Kudos to Isaac and his son on this job.

[@anxietyislandllc]

"Roached out" gives me memories of my teen years (mid-70's) and our slang. 🤣🤙

[@neilpuckett359]

They've got you hidden out back so customers can't see the old worn out machines being fixed up 😊

[@davidjshaver3771]

My father was a machinist, everything had to be precise. His buddy who worked same place for years was a truck driver, welder, fabricator. Was fun to sit back and watch them build stuff together. Dad's buddy would tell him aw don't worry about it get it close and it'll get used to it lol. Give anything to be able to go back even if only for a short time. Glad you and your son seem to work well together and your passing along your knowledge to him. Will help him out immensely.

[@Trey4x4]

Sounds like enemies from another life 😂 a match made in hell

[@ryane6719]

One could say he’s passing the torch to his son

[@hankimus10]

Love seeing a son follow in his fathers footsteps

[@gregorycross612]

Oh my, I finally figured out what I'm doing wrong! I have been eye-ballling things with my bad eye! 16:30. 🥴

[@Popeyes66]

" Where's the hammer " "Which hammer ? " " ANY HAMMER !!!!!! " 😂

[@Froggies505]

Man I’m starting to get into some of this machinery repair and not going to lie, pretty intimidating. You wouldn’t think so since I used to work for bobcat and CNH ect ect. Built alot of huge equipment but repair is much different. Thanks for all your effort I know the videos ain’t easy to make.

[@boydovens4180]

Building something from new can be challenging , but repair work on stuff is a whole new set of problems .

[@natedoerfler652]

Great to see Jr. in a video again!

[@58unclesam]

IC your hands are as steady and precise as many surgeons I’ve watched on KZbin, you are credit to your trade!

[@Hugh1966]

“ eye balled it using my good eye “ ! Gotta love Isaac classic humour.

[@Grandpa82547]

Thanks for another visit to Isaac's Engineering Machining Welding and Education Services.

[@EFD620G]

my grandfather use to center punch a series of marks at the clock points. Even if the marker burned off, the punch marks were seeable.

[@FishFind3000]

I don’t think “seeable” is a word, I think your looking for the word “visible”

[@RowanClark-gr3cg]

I bet Kurtis watched this with great interest.

[@klausswartz3369]

Isaac, you’re a surgeon with the torch. Very informative, and the line borer earns it’s keep, once again. 👍🏻

[@lionsdejudah]

It’s GOOD to NOT hear you cursing, family oriented…

[@dylanrussell6925]

Puts ease to my mind knowing not everything has to be spot on perfect. I’m a pipe fitter by trade and always try to go for near perfect but in equipment repairs it’s not always that way haha. Awesome work

[@tacomas9602]

With as many hours that skiddy has even if it’s off a tiny bit it won’t hurt it. I’ve found maligned booms straight from bobcat, new.

[@jasonpatterson8091]

You've mentioned line boring a number of times in your videos but I don't know if I've ever seen you doing it before. Interesting procedure, thanks for sharing.

[@dirtfarmer7472]

CCE from Australia has done line boring on several jobs. Also Fire creek welding from Califorina. They’re both very interesting to watch. I’ll bet that you will enjoy both as well as Issac

[@malliz1]

​@@dirtfarmer7472 CEE cutting edge engineering on youtube

[@dirtfarmer7472]

@@malliz1 That’s correct

[@charlescastillo8870]

Everything has a bit of tolerance for adjustment plus nothing a ten pound sledge hammer can't get precise even with your one good eye. IC jr is really coming along, I can see the confidence he has doing more. Give him some time with the gas ax and plasma cutter, I see his welding has improved in previous videos. As usual great video and very informative ❤

[@shawn081082]

I just watched a video that was all about the history of the Bobcat. It was invented by two brothers who were blacksmiths and welders. You should check that out!!!

[@ICWeld]

I saw it as well. Very cool video.

[@djmips]

Thanks for the tip. This one right? kzbin.info/www/bejne/mJfKdqVjo7V2rJo I'd say the brothers were farmers! Those old time farmers were very industrious and knew how to fix and repair any machine on the farm. This tradition still lives on today and I really look up to the modern farmers who still are able to work on their own equipment.

[@goboyz8016]

I have seen and done a lot of torch cutting but I have yet to be able to perform like that. So glad your son is with you to absorb the skills of a master. Great work as usual.

[@davedavedave52]

Ya your son is a lucky guy

[@nder12345]

Man your a magician with that torch. Excellent repair as usual. Perfect to watch with my morning coffee. Thanks for the videos from Australia

[@russellgilson4072]

Surgeon with the cutting torch, great skill set! Your son has the opportunity to gain invaluable practical experience from his Dad, lucky guy!

[@AreYouAwakeYet]

True JourneyMen only come from Father/Son Teams :) Love your work and I truly admire how you are teaching your art to your Son. God Bless and teach him well. This is the kind of training schools only wish they could do.

[@dangroce82]

That boring rig is slick.

[@thomaschristensen755]

I really like your content. It is real world stuff.

[@zeke1eod]

"My good eye" and "hope you learned what not to do" my man has jokes 😂. One of the best repairmen/welders I've seen in my 30 years of welding!! Awesome job, thanks for sharing. Stay safe, and God bless

[@chrismononen663]

I like your whisper into the camera " I don't want it that tight" the truth when you need to think on your feet.

[@BrucePierson]

Another interesting repair to get yet another machine back to work again.

[@localcrew]

It’s never “Boring” around here.

[@andrewseth3998]

Look up “Presto” jumbo correction pen. It’s like a ball point white out pen. Works great for marking steel and will hold up to the high temps of a torch!

[@mikemccrea1935]

Yes I seen that on a video recently. I kept trying to say that in the comments but I mentioned the other KZbin welder I seen it on and my comment kept getting removed. I’m assuming that’s why it wouldn’t stay up

[@rugerfarming5387]

That looked like a easy one compared to the backhoe frame that was crazy. Good Job.

[@dans_Learning_Curve]

Worked at a Bobcat dealership for 2 years. They had a tapered reamer to fix the wallowed out tapper. Maybe these were past repair.

[@allenbrown7820]

That depth of cut on the last arm would have made Kurtis jealous. 👍 Keep up the good work and Be Safe.

[@57WillysCJ]

Nice work. Watched a video on the history of the Bobcat skidsteer. Invented by a guy with only a 6th grade education.

[@davidsellars646]

Probably the most precision on that old girl. When things are that worn, you just have to do the best you can and you did very well.

[@micmike]

Nice example, you had me worried about the alignment but I shouldn't have doubted you. Hahahaha, thanks for the video!

[@thedelcodave]

Thank you for these videos. I have learned how to torch like a pro from watching you work. I put my skills to the test the other day and my torch cutting project was a success.

[@bpedoniquott7971]

Patience only asking directions ..your the teacher lucky to have you

[@oldstudbuck3583]

You’re a great father and teacher.

You make CEE Engineering with his shop boring bars look like he’s working in a palace. Great on-site work.

Thank you Isaac and son. You two make the miserable jobs look easy.😊😊

[@michaelweatherhead9470]

Thanks for the video Issac great job on the Bobcat your Son is learning the Craft from a Great teacher. Take care of yourself and family and be Blessed ❤️❤️👍.

[@charliemclaughlin1042]

Freezing your bushings helps alot

[@Daniel_cheems]

Another excellent job out in the field with a hurry up customer. Well done Isaac & Son!

[@jwaterous224]

You rescued that Bobcat! And made your son very happy since he is working in the field with you. Good result well within tolerance.

[@stevebreland389]

Excellent! I’ve wondered how the line boring is done. You presented a clear picture. Thanks.

[@jeremymatthies726]

I had to laugh when you said you didn't want to bore us with the second one....but you were boring; the machine that is 🤣. I see your son is coming along in his confidence of what to do and what is needed, keep up the great job mentoring and teaching him. Looking forward to seeing what you have up next.

[@cwduch]

Totally missed an epic dad joke opportunity. Made up for it with the mega dad energy reply to the ‘which hammer’ question, “ANY hammer”

[@jerryleejohnsonjr1377]

Great real world example of how to get it done, Thanks for the video!

[@nope4239]

As usual great videos Glad to see your son help you on this one Thanks men it was awesome

[@keithficke9250]

I enjoy watching your videos

[@assassinlexx1993]

I don't have your skill with a torch. I would use a magnet drill press with Annular bits. You do a great job fixing equipment that has been thrashed. Always great to see your son learning.

[@williamthomas9463]

That was my thought as well. Might have saved the line boring but would have been harder to line up the two bushings.

[@hartex57]

I injoy watching your show. I was a finish grinder and I was working with tense of thousands but I enjoy watching do line boring

[@bradbilskie8078]

Very interesting, great job you two.

[@repairrestoreresell2026]

No sloppy holes............Tight is right. Best of Luck.........................

[@burtlade1705]

Good job as usual. I caught mine before the tapered holes were damaged. It's good to see it done once in case I ever need to do the same. Thanks guys.

After watching many of your repairs, I have improved my ability to tackle more domestic repairs. Thank you Sir for sharing you knowledge and please continue to do so.

[@davidwalk9045]

You did a great job as always.. That great fix you did on that machine. Very humble guy.

[@MrRebar15]

*I C Weld* Bravo well done, thank-you sir for taking the time to bring us along. GOD Bless.

[@earthbreaker]

Good job, steadier hand than I have with a torch. If I had that job, I probably would have gotten my big magnetic drill out. Put a small bit in that fit that bushing hole to find center.. Then back the bit out, without moving drill and put in a 1.25 annular cutter bit. Then drill the hole out. Just need plenty of coolant and should not be to bad.

[@Dave_Smith_1958]

Another fine job Issac

[@olivermulliss7114]

Top notch, I would have used a mag drill to get the line boring machine in, only because my torch work isn’t anywhere near your level.

[@dr.feelgood2358]

I think it's great that you work with your son. I used to help my father doing electrician sidework on the weekends, and I learned a lot from it, particularly that I did not want to pursue a career as an electrician! seriously though, there is no educational substitute for shadowing a professional on the job.

[@stuartlockwood9645]

Hi Isaac and Nick, nice fix, good to see how a job like this is done. Thanks for another interesting video guys, stay safe, best wishe's to you all, Stuart Uk. ,

[@dirkkelly9596]

Great job 👍👍

[@markalexander5124]

I won't bore you with that, no pun intended.

[@johnpullman3227]

As usual you make it look so easy. Having the line boring rig and knowing how to use it is the key. When we did pivots last on my brothers bobcat a gas ax is all we had and the finished job looked terrible even after the grinding. All your jobs are done in such a well thought out professional manner. Line boring is one of those mystery jobs no one seems to know about. I've never seen a line boring rig for sale used. Are they all passed down from father to son? LOL. Thank you for documenting the process and making it look so straight forward.

[@sackvilleweldingservices]

Another fine repair young man!

[@patrickcolahan7499]

You sure have picked a good grade of carbide for the job! Really like that clamp on tool setter as well. It looks really well thought out in design.

Great job! that old Bobcat lives to earn another buck for the owners. Cheers!

[@johnscheffler1514]

Abom79 would be impressed with chips. Nice work as always. Your torch skills are second to none !!!!

[@KW-ei3pi]

Excellent repair as always! Only two minutes in, I noticed the area of repair was less than waist high. The loader arms could have easily been raised and blocked at a more convenient and comfortable work height that would have also made the repair go much faster. This is almost always the case, but seldom is this realized in the industry. In addition, the wear and tear on the body will show up later in life, but sooner than it should. Trust me. I know from experience .... unfortunately. Regards.

[@glennfryer1539]

Master and son at work 👍🏻👍🏻👍🏻

[@northernexposure9066]

Excellent job considering what you had to work with, that poor old machine looked a little tweaked in the arms.

[@sawboneiomc8809]

“I won’t bore you with that”.....I get it...I won’t “bore” you wile line boring....🤣

[@GCraigmile]

Outstanding work Sir

[@johnwesner3935]

Hey Issac, when I replaced the bushings and pins on my 79 Bobcat 530 the bushing were pressed in, not welded. Easier but still a pain! After digging out a ton of grease I split the bush with the torch to get it out. "Pressing" the new bushings in involved big hammers!:( The bushings were so bad that it wore into the arms on both sides. I cleaned them up with a grinder and was then able to put a big washer ( about 1/8") on both sides which filled the gap nicely!:) Works great! Bobcat wanted over $700 for the bushings and pins but I was able to find them on line for $250. Thanks for the great videos!

[@charliemclaughlin1042]

You always do awesome work

[@baratariaelectric2415]

Great job as always! Thank you for the video. I think the title for your video should be for a S150 bobcat? Don't think they make a S120......lol..... Will make it easier for the guy searching KZbin on how to do this on their S150 machine!

[@ICWeld]

Good catch. You are correct. I'll edit it

[@legionofanon]

Even when your content is boring, it's not boring. I'm used to the line bore that Curtis has and this was cool to see. Thought about centering the hole, what about using a reamer to bring the hole to your boring bar size, set the pads for the bearings then boring it out?
