I never dreamt that a track service could require so much thought and consideration to get everything right. Thanks Squatch

[@ron827]

We smart native Minnesotans know how important it is to plan for winter and Squatch is the best example I know of; fire wood made and equipment where it needs to be. The pressing stack is pure genius.The right tools for the right job and if you do not have them, make them. 👍👍

[@paulmanson253]

Well now. I think of all the bicycle and motorcycle chains I replaced and threw away. And I look at this one guy,this one video on how to recycle a chain assembly. And I think about what it would have taken to fabricate,tinker,purchase,and otherwise fiddle and experiment till I got it right. And all those winter nights I spent with the cat in my lap,the dog on the rug next to the couch,and my girlfriend nestled on my shoulder,all gone now,well I still did the right thing throwing the chains away. But it sure was interesting now I have an idea of just what it takes to go through the whole process step by step. Toby,thanks for this. I really appreciate it.

[@randyclyde4939]

I continue to gain appreciation for the mechanics of bygone times. Toby, that was most interesting and informative. Thanks as always, for your straight-forward presentation and explanations! Be well, be safe!

[@robertdonnell8114]

Thank you for this. My experience is with LIVE TRACK on tanks, similar but the inside and outside bushings are separated by rubber so that steel does not touch steel. Yes there is more friction when the track which are loaded at an angle (about 30 Deg) is forced flat by the first road wheel but you get some of that energy back when the track gets to the end and jumps up thus the meaning of "LIVE TRACK". I had assumed that DEAD TRACK was rather simple but the engineering is quite ingenious.

[@patricktobin1388]

As i have watched your fastidiousness with assembling the links and the track, I now understand much more how tracked vehicles work. And I admire your patience with a very tedious process!

[@mikef.1000]

And you're exactly right about the 'feel' benefits of the hand pump. Hand-operated tools might be a bit slower and all that, but the importance of feel cannot be overstated.

[@michaelbrash8843]

I understand your comment I'm a manual labor guy in a automated world. I still split my 2 cord of firewood by hand post holes by hand and so forth. That is what keeps me going at 72. Just a number.

[@johnwythe1409]

Nice work! My dad built presses for doing all that as well. Did about 4 sets for a D2, one or 2 D4, and TD35, TD40 chains. Lot of work to take apart and repress. Never was around when he did them, now I know what it looks like. Thanks.

[@acewrench]

Great walkthrough of the process, and I can appreciate all the work that goes into doing that process correctly and consistently.

[@michaelwest4325]

Strictly a DIY and home mechanic, I oddly rarely use my air tools and almost never the cordless when I work, handtools let me feel and better remember the work as I only do something every few years. So something about being manual in this world ain't so out of step for some of us!

[@TheJstewart2010]

I have to believe that your tool set must be pretty close to what Cat used when they built those chains. Impressive how they allowed you to get every pressing to exactly the right depth easily and quickly.

[@bishopcorva]

I like a manual pump for the ease in which you can sneak up on a loading with it, sure auto-pumps are nice and speedy and they have their place if you're wanting to knock out a lot of things quick. Still though, maybe not fully run the bushings down with the auto pump, but do get them 'set' and nearly seated so you can finalize it with the manual to see and feel if the press fit doesn't quite feel right as in too loose, plus the time between mounting and dismounting will give the links, pins and bushings time to relax and spring back slightly. It might not be much of a thing to consider, as to me, it's similar to needing to re-torque lug-nuts after so many miles and the process of checking bolts and so forth after so long incase of relaxation after torque cycle.

[@stuartmcewan9620]

All ways good to see your work. I was lucky enough to be able to purchase a new chain for my 3j D2 at a auction a couple of years ago. Old new stock. Still wired to the pallet. But I still need 28 track shoes.

[@shaneharrison4775]

A tedious process like that can be really error prone if you loose your concentration. I would have a tough time with that. Congrats on getting it done! Plus, more custom tooling! There must be a whole cabinet full of that by now. I’m sure it’s well organized someplace. You should have a video quiz asking us to I’d them all!

[@Shockedbywater]

About the pump, I used to work at a place with a 50 ton press that had a hand pump but we added an air powered hydraulic pump to it. We just 'T'ed it into the line so you could use either pump at any time. So we could bump the power pump to close things up but switch to hand pump as soon as we wanted to feel the load. You have to be OK with the fluids mixing and you have to try to release about the same amount back into each tank.

[@peterfallert4994]

Unbelievable amount engineering. Looks simple, anything but!!

[@Fatamus]

[@douglasmiller7618]

Get a foot switch for your pump, you have to remember to watch your pressure gauge, plus it gives you both hands to work with.

[@ronaldfairhurst2914]

When you started to talk about the new master bushings and pins I about had a stroke because i tried to find one for a D6 9U and couldn't find them, wish I had bought a set years ago, I made both the bushing and pin, so far seems to have worked out okay.

[@MacGyver-1]

Pretty neat to think that you will be wearing original paint off the chain when you start running that again

[@bcbloc02]

Can't you adjust the pressure relief on the enerpac so say it would be limited to 5 ton so you would avoid any disasters.

I could see building a fence on the receiving cup to Aline it with the link to offer one less thing to hold on to while pressing. Great work.

[@rinardman]

In the full spectrum of excitement you start with "about as exciting as watching paint dry". I think the next step might be "watching pin & bushing pressing". Somewhat boring unless something goes wrong....and then it gets real exciting for a second or two! 😁

[@charlesward8196]

It seems like the hand pump is better for the disassembly of the track chains since there is unknown excess friction/resistance created by corrosion in the push-fit area, leading to the chance of excessive force being applied to the press or other components. Without reviewing the previous video, weren’t some of those pins “popping” at 50 tons? By the time the pins are cleaned, wear shoulders beveled, and PFL applied, the press-fit force required would be much more uniform, like 30 tons, (?) and less fraught with high-pressure mishaps.

[@johnraynor5095]

I was surprised that you had end built-up the wear side of the links.

[@kevinoscarson2941]

If you take the links and put them into a oven at 350 degrees, then put the bushing into a freezer, they will start easily by hand.

[@kevinoscarson2941]

@@squatch253 - they still will take a press fit to put them together, it makes for a much faster setup, avoids misalignment, and takes less force. When ever I did chains(I only replaced sections of links) I used this method and the equipment was all D6-D8 size, these rails were much worse than your D2s. Also during disassembly you will find any loose fitting pin/bushing. They all press at a minimum pressure, if one goes easy it’s likely junk.

[@aserta]

Looks like you guys got powdered... here it's still 14C out. Very cool solution you figured out at 8:16 as an answer to their track chain pressing table. I saw one in the old magazines i peruse, and in essence, you've got the same result, but with a much smaller "outfit". Cool, cool.

[@LoggerLloyd]

Great to see your process and home made tools to make it happen. Any thought of having a support of the other end of the link to help insure alignement without having to hold it up until pressure is on the side you are pressing?

[@93Martin]

there was one shot of a pin pressing into a link (timestamp 20:20)that had a perfect view of the wear line in the pin, but the video jumped to another pin being pressed in. I would have liked to see that wear line as it reached it's resting position. idk how much trouble it would be to add in to the public feed video, but I thought it would have been a good visual. And maybe I was just looking forward to seeing it too :) Can't wait to see those swampers on there!

[@seniorelectrician6831]

Thanks for explaining that!

[@RuralTowner]

The guide for the last bit of pin travel. Might it be a touch simpler to have one in place during the initial press with an opening just big enough for the pin to fit through & just thick enough to achieve the needed extra distance? Would help a little with the tedium of resetting to setup again then continue. Or doing this way to make it less likely it slips if doing the above method & send bits in 3 directions?

I like the pump I hate the noise we use the same pump to crush hard drives. You should really be wearing ear protection if you are not.
