What size is the nut for the track adjuster? Every tractor is always different you never find two identical ones in terms of wear and tear. The chain might be wasted but be lucky it's not a D8 or D6 than your in a very expensive territorry. To me it seems the back end might be very good on this machine. The upper carriers are done cause sometimes people don't know there are grease fittings on them. This can not just happen from pulling to the one side.
The adjustment nut size is a 2-3/4 inch. 9F3869 caterpillar adjustment wrench. Fortunately the size is the same on all of the first generation D4s. The bad thing is there are no chain replacements. I have heard there is a place in Italy that makes some that could be modified. Unfortunately a donor tractor or donor chains are the only option. 👍
@@lifeafterourloss With chain replacements the modern excavating equipment tends to use metric links instread of Imperal size links. So finding something that fits without modifing the sproket is going to be a impossible challenge. Might still be worth investigating but i doubt there is a modern analog chain in use that would fit a D2,D4 or RD-4. 2-3/4 inch would equal a 69.85mm so the closest is nr 55 metric wrench that is in use as a track adjusting wrench for the Soviet CAT clones.
When you adjust the tracks on the early 4G's the whole recoil spring and front carrier roller move forward (or back). The other nut that is inside of the adjusting thread holds the tension on the recoil spring and that tension is determined by the length of the spring as referred in the manual. Cat changed to single carrier rollers because of dirt and trash build up around the roller causing excessive wear and also the grease point was often hidden. Would love to have a collection like you guys have got
The design evolution, just in the 4G series is fascinating to me. I've noticed certain wear patterns on the tractors we have. Many of them indicate exactly what you mentioned. The more I learn about them, the more I appreciate them. Design changes, engineering, logistics and manufacturing during a production run is impressive. It is truly a testament to caterpillars commitment to quality.
@@lifeafterourloss Absolutely from 1931( first diesel) to 1940 Caterpillar went from all gas models 30,40,50,70 to nearly all diesel D4 D6 D7 D8. They were also being pushed by Alice Chalmers and IH as well
Interesting combo of worn and not so worn undercarriage on old Right Guard there. Good looking tractor under that mess of hydraulics. Good plan to run-in those stuck chains. That little pony exhaust flapper is a great find!
I hope you make as much as possible d4's running ones and take off stuff that does not belong to them, like all home made stuff (or it is a working blade) and not put paint, just patina with a coat of boiled lindeed oil, so less work not painting them. made technical perfect or at least running. (Just like you were doing on this one.)
We have big plans. Some will be restored. Others will be fixed to working condition. We also have some "special" projects planned for at least one. 👍The home made stuff drives me nuts. 😊
Thank you for saving the tractors. Would have been a scrapers dream. I love the videos glad to see big stripes is doing good. What is your guys goals with the collection ? Any special machines you are searching for
We're always on the lookout. Ideally if we had a 2T series D4 we would have one from each model of the first generation D4s. Some will be completely restored others will be restored to working order. Sadly some are just relegated for parts because they are just too far gone. 👍
Hello Greg and Aaron, you guys have a great addiction. Everything you both do is a challenge, sometimes I watch you and think, they just keep on going, WOW. Ha Greg thanks for buying all those old Caterpillars. Lefties tracks may free up. Also, Greg you do love the touch, and Aaron knows it. Thanks again for sharing. Glad Big Strips is doing well. Aus Peter✌

@@lifeafterourloss PS! the home made tool is for removing keepers.
It's good to see the smile that Big Stripes brings to you! I think your Dad got himself a nice Cat too.
It was a good day when you got Big Stripes back.👍😎
She is a sweetheart! 😺
Wonderful plan. You are getting a significant cat collection. Nice to see these old machines staynout of the scrap yard.
We have definitely committed to these pieces of History. 😊
That’s a nice machine. Lots of possibilities with it.
Is a very good runner too! Unfortunately it has to be push started at the moment.
Buzzsaw is a great name 🤩👍🏻😄
❤❤❤❤Good job the collection grows its not easy to strip one for parts as they are all good 👍👍👍👍👍👍
We are very happy with the condition of these machines!
That is too nice machine to be parts tractor, it needs to be used like that, thanks for showing us. Little kitties need attention too.😁
I think down the road we will get the pony motor working and just keep this as he is. 😺

You are liked a great mustachioed Squatch teacher on what makes these so great to collect 🤩🤔👍🏻😀

Thank you! You will see in some future videos that this tractor and I actually form a bond. 😊
You guys have been bit by the old iron bug!
We definitely have! Thanks for supporting the channel! 😁
Hoping all the family gets well!
Thank you!
Nice intro to the fleet...really like you video! Another good and fun one.
It was actually quite a bit of work to get those arms off of the tractor. But it really looks a lot better.
I've never met a stock bolt/nut that varying amounts of heat won't persuade one way or another!
Thanks! Anxious to see how your plan works!
We have our fingers crossed! Thanks for supporting the channel.
really cool

Wire that gen. in right and you'll be able to start the pony motor and charge the battery that runs it

Is Big Stripes cat scanning the machines before you work on them?
😺, definitely! 🤣😂🤣
👍👍
