I'll bet you miss the good old days, when you could just go into your workshop and fiddle with your Johnson for a few hours...

[@carsonwashburn1]

We have all made stupid mistakes, but I give you a lot of credit for leaving those parts in your videos. I have learned so much from your videos over the years.

Anyone who's done heavy equipment repair fully understands your sentiment regarding winning against that pin!

Yes my back hurts as I watch his videos

[@carrollfranklin9807]

Worked in shop that rebuild tracks . We had a 100 ton hydraulic jack and i have heard that pump scream pushing pins out . When u started that job I was glad it was u and not me . U did good .

[@Notsoshadyacres.]

Good morning John, I’m not a metallurgist but I do work in a very industrial zone in Canadas far north. We recently have had a series of injuries caused from swinging sledge hammers on hardened steel surfaces. One guy had a chunk fly off and insert itself in his hand, another in the face and another in the chest. The fix was leather wear, face shield, and a brass or soft sledge. I know it doesn’t seem practical for all of that but I thought to share some news. Your one of my favourite channels to watch I’d hate for anything freak like that to happen. Keep up the great work!

[@erikcourtney1834]

Hardened steel should never strike each other. There’s a reason blacksmith’s striking tools have been tempered way back or not hardened at all on the struck end. Or even use a soft face hammer. When they chip, those pieces are flying extremely fast. But I doubt those pins are very hard at all. I’d bet there made of 4140 or 4340 and heat treated to be very tough and not Hard. They aren’t going to chip.

[@RossReedstrom]

@@erikcourtney1834 Right, if they were hardened, they first one wouldn't have mushroomed like that.

[@SantaClaw]

My Grandfather lost an eye drilling using a chisel and sledgehammer whilst doing his job as a road worker in the 70's. In Norway, sledgehammer work safety is taught in school now for construction workers. Basically, the real "killer" is when the sledge or the chisel gets mushroomed, the sledge will knock the slivers off the chisel and those come at you at supersonic speeds.

[@SantaClaw]

@@Channel-gz9hm OOO look at me being all hip and down with the kids. Based on how this particular youtuber seems to be somewhat safety oriented, the OP's point is absolutely valid, it's what you don't know about, that will injure and kill you. Ignorance is bliss. Until someone loses an eye, or gets a metal fragment stuck in another rather important bit of your body. I mean, I could have made a stink about using a 7" grinder disk on a 5" grinder, and how that is insanely dangerous, as the smaller the grinders are, the faster they are made to spin, so using a 7" disk on a 5" grinder can cause it to explode, sending shrapnel into you since the disks are not rated for that speed.. Goddamit, look what you made me do.

[@anonyymi7630]

A long time ago i struck the edge of an anvil hard and a very tiny piece of metal flew into my knee. Didn't even notice it at first, but soon my jeans were soaked with blood down to my ankle on that side. Luckily it didn't cause any actual damage.

Try Sampson Boat Co with the rebuild of Tally Ho. It's great. There's still a long way to go with that one but the craft of wooden boat building s over the top. Paid for by viewers. Another one is binge watch Project Binky. Apart from being hilarious what they do is amazing. It started in 2014 and they're still going. Blondihacks, This Old Tony and of course AvE.

Best of all is Marty T from New Zealand. Very skilled and makes do with parts he makes himself. His recent conversion of a gas powered ATV to electric battery was amazing. Check him out.

[@GrowthCurveMarketing]

I've finally figured out the main appeal of these wonderful videos. It's not the practice of excellent general mechanical skills, although there's that. It's not learning about the demands of a modern small farm, although it certainly shows that. It's really about persistence overcoming adversity. LOL! Great stuff...

Welcome to the world of iron tired tractors!! The big rule heat is your friend!

[@RichardSothern]

Been doing this for 50 years. I’m 75 now. Torch a 3\4 inch deep hole in each end of the pin. Let the pin cool. Drive the pin out . Using a smaller hammer and punch. The cost of a new pin is nothing compared to the labor cost. Also relieve the track tension before doing any of this.

I love when you buy a piece of used equipment, as it leads to a series of great content from you (boom lift, dump truck, excavator, and especially this dozer). I also love that you always share your struggles (even when you do find them embarrassing during the editing process). Can't wait for your next project.

It's such a treat to see you use so many improvised tools that allow you to use basic machines in interesting combinations to put force where you need it. Also, the joy of having to do the process twice, you get to swear and curse during the first go round and feel like a genius on the second once you know what to do.

Sitting down after a long day at work and watching John use his brain always makes my brain happy. Thanks John!!

[@InLineDiesel6]

Flipping the bird to the pin was simply priceless! I'm still LMAO, even showed the wife, she said you definitely earn the right to do it.

[@tallokie67]

Great work! In my experience, I've mushroomed more pins/shafts with a sledge than an impact hammer. Adding support like you did on the left side probably helped the most. The key is to try not to put too much heat on the pin and keep it on the collar. Heating the pin just makes it bigger and if too much heat, like you showed, will forge/mushroom it.

[@Bob_Adkins]

Not having a helper was the biggest handicap of all. A helper could have held a pointed punch that fitted the dimple, which would have prevented the mushrooming.

[@wxfield]

We use a demolition hammer on our farm. It's heavy so there's a bit of an effort with the forklift to hold the hammer at the right angle/height. We also tack-weld a cutoff piece of pipe around the pin. The hammer goes down inside the pipe and centers on the pin. The pipe is there to act as a guide. Try to hammer anything with the demo hammer freestyle and it's uncontrollable. Pins always come out very easily for us using this tool. But like I say, a bit of a setup.

[@akdoug6437]

I came here to say the same thing. We use a 20# Makita electric demo hammer to remove pins on all kinds of machines.

[@jpolish420]

The thing about heating metal to make it easier to get out the pin is that its not about just getting it hot, its about getting it hot fast. Once the heat transfers to the pin, it also grows in size and just as tight as when you started. Use your biggest rosebud heat the link fast, take your best shot and if you don't get it you'll have to wait until they both cool down before you should take another shot.

[@brian_2040]

Ive always heard the wet pin rail has the gator clamp. The dry rails have a master pin with a big cotter pin or similar pin holding it in. The welded pin is probably the most common though. Mr John you worked your tail off on this job. I can't help but say this, when you were showing how great of a job you did fixing the slides I see the mast for the blade frame has a fair amount of movement in the pins. I wish I could be right beside you, getting to know you and get some work done. I love these old machines too. I'm sure Kurtis from CEE Australia would be proud of you on this job.

[@Golden_SnowFlake]

The best part is where you spent all that time taking it apart and welding it due to all the years of abuse, and while everything is still loose and easy, decided not to put the washers in. I am like that too. I also often regret my past decisions. :D

[@gordonagent7037]

Jon, I know you keep having little problems but we both know that in time they will be resolved and it will be a pleasure to work this little cat without those worries. Buying anything second hand is basically buying other peoples problems but for sure, you are the man to sort them out. Well done mate, that was a really great repair and another problem ticked of the list.

[@dennisfoltz7880]

It ,s common for the tracks to be serviced by pressing out the pins and bushings and rotating them so they wear on the other side . It might be worth it to see if you have anyone in your area to do that .

[@johnhook5755]

I have a 1974 CAT D3 dozer almost identical to yours. To easily remove the tracks, just push the blade all the way down, completely collapse the track adjusting cylinder and lift the track out over the front idler. Very easy and quick method of removal without driving out a track pin. I also noticed on another video that it looks like the brake pedals need adjusting. Look in the manual how to do this correctly.

[@ronm3245]

It's so satisfying when slop in the system is reduced.

[@WonkyStud]

I'm a sysadmin myself, I guess problemsolving is a glitch we all share :)

[@neffk]

At 35:35, you pre-heat and say something about penetration. I think pre-heat helps avoid cracks due to the rapid cooling because the casting is a giant heat sink. Pre-heating is probably the right thing to do. Depending on the AR alloy, I think post heat might be good, too. The Lincoln Electric book says you've got to be careful if the carbon is above 0.4%. Cast iron is 10x that and I think some of the AR alloys are pretty high. Hopefully it won't be an issue.

I’ve always used a stick welder on equipment like this. I’m able to really burn her weld in compared to wire. Always felt it was stronger/better. 😊 Enjoying the maintenance videos. 😎

[@FarmCraft101]

I need to get at stick welding. It’s on the list!

[@justinthomas2458]

Should have thrown some 7018 rod in there, the mig wire is really soft in comparison.

[@InsanePacoTaco]

I have a question: when welding on something from the underside, does the weld behave differently? Like does it tend to form peaks instead of flattening out if you were welding on the topside? Or does it just cool down & set so quickly that it doesn't really change much? I suppose it also could vary on operator skill and the welder settings? Have it put too much energy into it or go too slowly and it'll stay molten longer and do odd things?

[@robertmencl9169]

@@justinthomas2458 mig wire tensile, like stick wire, is first 2 numbers of the filler material. It doesn't matter if it is stick or mig, 70 Ksi is 70Ksi.

[@robertmencl9169]

@@InsanePacoTaco welding from the underside is called overhead position. Overhead is simply a flat weld being applied from the other side of the steel. The heat setting, travel speed, rod angle, etc technique are the same as flat position, the only difference is psychological, and to a great extent, there is difficulty in seeing the puddle which is obstructed from view by the stick or mig gun.

Made it like new. But still a rough riding...dippy machine. I was good at operating it because I was energetic and going. Had fast feet for the pedal steer and quick hands for the shifter with spin throttle knob. I would try hard. My older dad couldn't stand running it...and all the older operators as well. Had to sell it cause I couldn't hire any help that would run it. But, if you slow down...it's a sweet unit for home and farm use. At least it has no electronics!!! Good job on the video! Keep it up.

46:50 it still helps when the nut breaks loose that it doesn’t bind up when running down the bolt.

[@David-yf5fo]

I have done several of these things longer ago than I care to remember. Park the machine where it is flat and level. On the starboard side of the machine, position the master pin on the front idler, between 5 & 6 o'clock. On the port side, that would be between 6 & 7 o'clock. That helps use the weight of the tractor to hold things firm. Do not remove the track pad! The track pad helps hold the links firm, keeps the links from moving about or bending, and holds the bores in the links true to one another so the pin does not bind when driving it out. In a vintage 1950s manual for a D-7 (17-A), Cat shows a jig for holding a punch that clamps to the track pad. If I did it more often than I did, I would have made such a jig. I often used lumber and mounded soil to create a cradle for holding my punch at the correct height. An 18" long piece of 1-1/4" mild slick rod is recommended for use as a punch though that might be too large for this tractor. Please do not use you foot for holding the punch in position while hitting it! Hitting the punch square and with nothing less than a 20 lb. hammer is normally what it takes to drive these things out. Heating the links to remove the pin is not recommended for reasons shown here. Always replace the seal on adjustment cylinder when breaking the tracks on an old machine like this.

Great videos, as a dozer owner you were right! Just a little painful watching you learn to back up the pin and get the biggest hammer in the shed. Always use new hardware, bolts and nuts.

[@johnmiley458]

used to work at a large construction shop years ago. Your second hammer and the bucking pipe and letting the track adjuster lose helps. We always had someone handy with a railroad pin hammer to hold against the pin. The best hammer for that job is a 16lb hammer. The 12 is a too light and the 20 takes a real big real good hammer person. You are doing a good job . Especially working alone.
