Caterpillar SIXTY Rebuild Project - Disassembly Part 4 removing #1 and #2 cylinders 

Quality audio is by far the most challenging part of making videos like this in my opinion. Keep up the good work!

Might have to change your name to Ironing Board Man. Seriously, I’m enjoying watching you work. My 6th grade teacher said, “always show your work”. I never learned.

Seized cylinders are always a challenge. The best way to do it is hydraulically. Before you get started save at least one head gasket. You just have to clean up one head. Make sure the valves are seated positively. I like to blast the trash out of the cylinder with light sand. Blow it all out and soak it down with weasel pee (PB Blaster, Nut Kracker or Sea Foam are my favorites). Put the head back on and torque it down. Then fill the cylinder completely with old crankcase oil (or transmission oil, whatever takes your fancy). Take a piece of shaft and spin out an end like a spark plug so that it will thread into the hole; a couple of flats on the outside will accomodate a wrench. Bore a hole down the center and then carefully cut a female 1/8" NPT into the opposite end (Use a good sharp tap). Thread a Lincoln grease gun or equivilant directly into the adapter and start pumping. A good grease gun can put out 3,000 psi. I came across a John Deere D that was just as hopeless as this. One piston went solid a few times but after a couple of coffee breaks (not to mention several stories about the good ol' days), and it gave a grunt and broke loose. The other cylinder wasn't so reluctant. Made kind of a mess pouring that oil out of the cylinder but the pistons came free. Took a good Sunnen hone to the cylinder. There were lots of 'freckles' but the ring lands were still good on the pistons. A new set of rings and the tractor was on its way to an otherwise complete restoration.

An older gentleman near me who has since passed was a wealth of knowledge. He said he would pour about an inch of diesel fuel on top of piston and light it on fire that the fuel oil would help to keep piston cool as cylinder wall would warm up slowly and fuel oil would soak down. I did that with the one of mine which was incredibly tight, I don’t know if it helped but I got it out. Oldfarmjunk101 has a video of doing that on a Farmall H.

Very very very inteligent machine..... majectic work for construction!!!!!!.. I admire these engines!!!.. .....................

Cracking series, each episode just the right length, leaves me wanting more. 🇬🇧🎅

The audio was just fine. New to your channel, enjoying it very much.

Can't wait for the sound to be fixed. Keep at it Nathan.

Glad to see you're making progress Nathan! 😁👍 Sorry to hear the cam is not usable, but I'm glad you could scavenge other parts you need. Like you mentioned, numbers matching isn't always possible on old iron. Sometimes you take what you can get. Either way it's gunna be a neat machine once it's up and running. Take care, be safe and keep wrenching. Talk to you later 🔧🔩

I free'd up a stuck Cat 20 by setting a chunk of dry ice on each piston.

Poor audio? Lol We are all armature audio video recorders. It’s all about putting your heart into the restore of these giants. Love the smoking con rod bolts!

I have been using acetone & automatic transmission fluid as a rust remover/penetrant. I am a real fan of PB Blaster but the home-made version seems to work even better than PB Blaster.

The crank on mine had a fair amount of pitting, I polished it and I’m sure it will be fine. On mine the biggest concern is the center main with the thrust bearing surface. I took the main caps off before I even thought about turning the crank. With the main caps off I jacked under the flywheel and a little pry under the front of the crank to take pressure off and it was possible to rotate the bottom half of mains out and facilitate polishing the crank all the way around. Numbers matching may be nice but having a running one to enjoy for me would be the priority. I’ll keep watching, it brings back good memories but I’m glad it’s behind me!

I just figured the audio problems were because I live in Australia and it's a long way for sound to travel......🤔

Awesome. Thanks Nathan.

Great progress Nathan! Sometimes viewers forget this isn't the Discovery Channel with professional audio techs, cinematographers, and state of the art equipment; it's RU-vid. I didn't think your audio was all that bad compared to others. Enjoy the content my friend; keep em coming!

Thanks Ironman, love this old machine and being with you on this journey.

Keep up the good work! Love your channel and what you're doing.

Thank-You for doing this series on the Cat 60. When I worked Road Construction we never worried about numbers matching, we only cared how quickly we could return a piece of Equipment back to work which usualy ment a short block and sometimes no matter how good You take care of stuff the Companies would buy auction Equipment that would just make You shake Your head on how the previous Owners managed to crack the Block or put stress fractures completely throughout the Transmission Case.

The rust when you took the side covers off looked bad but when you got the rod caps off it looked surprisingly decent. Thanks for sharing and saving the old iron!!

Your doin a hell of a job and the end result will be well worth it , this old stuff throws us curve balls now and again as we all know , great job

Nathan, what I have found is use a wire brush to clean the rusty threads before you take them out off. And perhaps you ought to put the side covers back on the Block and just fill the crankcase up with diesel and acetone and let it soak for a couple weeks.?

About 7:00 ----- had a bed that sounded like that.

Cool been waiting to see how rough it was inside it wasnt to shabby crank wise I sure hope that cam cleans up good sugar rust can be a real pain but should clean up fairly well providing it's not putting big pits in the machined surfaces. So far so good best of luck in getting it all apart and cleaned up.

The last Avery 50 that i did the cylinders on, i sleeved the sleeves, I do not know your shop well but a good 4 jaw and time and you can make them just like new. also if the pistons are rough they can be turned down a skosh and sleeve to fit, good as new. no matter what way you go good luck. great series.

I was going suggest the block of wood and a hammer 🔨 but 😊👍 I love the ironing board work bench !!!! I have 2 of my own lol 😆 😅

I use a front end loader for pulling engine parts like you do but since I don't have anyone to operate the lift I position the forks above the load and use a chain hoist hanging from the forks as my mobile crane. This way I can lift with the chain hoist and monitor the part I am lifting.

Thanks for sharing I seen a old guy put wd40 in a gas engine through the spark plug hole and he rigged up a couple to his air hose and put pressure to it seemed like it helped force it into the rings cause after he did it the engine started to free up but it could have been barely stuck hard to say I just

I’m for doing what you have to and save the crawler.

NICE JOB

I don’t know how I did it but I had to lift the cylinders with piston and rod assembly by hand as my ceiling was too low for any kind of lift. I don’t think I could do it again.

Hope you don’t get tired of me commenting. Are the cam followers stuck in the guides, mine were stuck very tight. I hate to admit it but I broke one cam follower guide pressing the follower out. One piston took 20 ton jack in my press and heat to get it to move, kind of scary. I had an inch thick plate just slightly smaller than piston to press on as I was worried about possibility of breaking top ring land but all turned out well. The press really jumped when the piston first moved. Good luck!

"... these heads are heavy ..." Is there anything on the SIXTY that isn't heavy?

After the first holy moly I said to myself, you’ll be saying that quite a few more times before this is done, not much later heard it again already.

Oversized Brass Nuts? Yup, my Cats have Oversized Brass Nuts. All my pony motor exhaust manifolds have Oversized Brass Nuts.🙄

I feel so bad, 😱 how the HELL did I miss this series ? Sorry Nate, 😳🤷‍I'm at a loss. WWii well that don't look nor sound right - Worth Watching Twice WWT much better.👍

The keyboard mechanics are all going to gripe when they don’t like what you are doing. Fuck em. Let them post their own RU-vid videos!!!

Paul, you have it all wrong. I am just kidding with that reply and Nathan knows. I have talked to nathan and he and I know about the sound
