Caterpillar SIXTY Rebuild Project - Disassembly Part 7 pressing out pistons 

Grandpa said, “Take that big hammer and give it a whack”. Out it came.

I'm not mechanic, but I enjoy watching your videos.

As a young engineer in the 70's, I came across piston pins that did not have circlips to retain them, instead they had aluminium pads that fitted into the pins and ran up against the cylinder. These were British made Gardner engines. I know the Cat C12 don't have circlips. This video has just told me that this arrangement for retaining the gudgeon pins (British terminology) has been around a longer than any engine I ever worked on. Thanks for educating me Nathan.

A hammer is a good tool when used correctly, the amount of persuation applied is tied directly to the size and force of will the man swinging it puts into it. Good stuff Nathan, been fun to watch so far

You know the pistons are stuck when you gotta break out the porta-power *and the sledge!* 😮 Nice work getting them free fellas! 😁👍

Missed the last couple episodes but really enjoying these. There use to be a old Cat sixty where my grandparents live. Last I heard it’s long gone, went for scrap unfortunately. Use to be used for plowing the roads in Mine Centre

Working with your Grandfather. What a blessing. Good for you

What a battle it's going to be to get that machine running.

I’m glad it worked for you. I wouldn’t have had the nerve to put that pressure on 4 studs.

Them were in there pretty tight!! Hydraulics for the win!!

I was literally doing the safety squints with my eyes when you grabbed the sledge and smacked the jug 🤣

I've got a sixty that needs the engine unstuck and rebuilt, also on mine the tracks are rusted solid. Haven't worked on it for a few years as time don't permit.

I love these Sixty Cats, I get to operate one every Labor Day weekend (about 30 years now). The 2021 show I was even able to bar start it for every parade, after the owners rebuilt the carburetor, but the 2022 show the float in the carb was giving us problems so I took the 10 Ton Holt through the parades. I hope the owners can find a better carb. I love these Sixties.

Excellent use of porta-power.

WOW !

Good job. Happy new year Ironman 13:58

Well that worked! Good job!

Wow those pistons were in there pretty solid my dad had an old GMC tractor late 40s early 50s the pistons were seized solid and dad wanted me to try and make it run as it was a rare engine that werent widely used with a binary transmission. Lol i sealed up the crankcase and had 4 five gallon pails of deisel additive a company used as parts washing solvent. I put all the covers back in with double gaskets. And filled the engine and its cylenders and upper valve assemblies and left it to set for a few weeks ended up leaving it for a month. Dad was not happy in my choice to let it set so long. Anywho when i retuned from a job i took miles away and pulled the tractor into the shop and drain the engineof the contents and most of the seized parts had loosened up in varied degrees but did disassemble with relative ease. And most of the engime was salvaged except for the paper pressed timeing gearswhich were well passed their prime. It was a lengthy process but the additive did make short work of the recovery.

"There is nothing that the proper application of hydraulic pressure cannot overcome! Which I've adapted from my Jar Head buddy's that say "There is nothing that the proper application of Cemtex and Detcord cannot overcome! LOL!

Happy to see a new episode! Just in time for me to relax with a beer! Happy New Year IronMan!

That works. I was wondering about the 4 bolt plate but I see that you already addressed that. Thank you Nathan.

this and forgotten weapons "rico special" video could make a really cool edm trap dub. As is, very cool video, really appreciate the time and effort you took to make this video, since i will never see a 60 otherwise. great series. thank you.

HAPPY NEW YEAR I'm looking fwd to all the trails and tribulations of this rebuild.

Happy New Year! and yes I am enjoying this Channel of yours as it is just great to share what I have done all my life to recover all gear similar to this, and I know how you feel. Just keep on getting on and you will be quite impressed with your results I am sure!

It worked out good!! The one gave you some trouble but a couple of 'love taps' with the sledgehammer and it seen things your way.

Happy New Year Nathan!

Thanks Nathan and Happy New year.

That's rather ingenious. What's the bore & stroke on it? Those pistons are fairly impressive.

It looked like it worked good 👍 👌 😅

just wondering, could you put the good parts in the original block, so it is still close to as ship?

Why are you swapping entire blocks? Why not swap just cranks? Then you could retain a numbers matching tractor. Just wondering if I missed something. Those pistons are amazing! They are like locomotive size! What was the design reason for the individual jugs and why did they stop building engines like that? Good series.

Whats the otc power pack cost? i had one given to me hoping it will run my 30 ton hollow Ram! single hose spring return !

When you look at it torn down,There really isnt much metal in that block!

Glad to see the Rocanville oil can being an integral part of the teardown any chance i can get your email Nathan ??
