800 Horsepower C18 in a Million $$$ Wood Chipper has serious engine problems.

In this video we are working on the most expensive machine I have worked on in awhile. Cat C18 is pushing coolant every time logs are put on the chipper belt. @AdeptApe on Venmo or [e-mail] on PayPal for donations, thank you so much for supporting the channel!

I bought the\ same impact as you have and it broke the very first time I was using it taking the wheels of my dump truck. I took it back and bought the same one you used at the beginning but with the long shaft on it and am I even glad I did.

If you watch the torque test channel they found the 1 inch pistol grip milwaukee makes all of its power in forward. In reverse it does no better than the 1/2 inch.

Always nice when the customer is willing to spend the money to make it right

[@mileaux]

100%. in my opinion, though, it’s not always about the money being spent but also who is doing the work. a lot of shops and mechanics have stopped caring about their work and have shifted more towards making money upfront than doing quality work and in turn, making repeat customers.

[@DavidTressmer-el1kg]

Hey Josh- see if you can have the owner call roto chopper to find out if the plc can be programmed to accept a EG sensor to reduce feed rate at a set point. That C18 is considered a small engine in that class of machine. The duty cycle and egt’s are at max, especially with some of the material sizes that you guys have out there.

[@Southalabamaoutdoors]

These Rotochopper machines are the best rolling drum choppers. This was invented actually by a rural Minnesota farmer. They can grind almost anything. The great thing about the company is they keep everything for the machine in house for repairs.

[@oldcatmech]

Your down this far, I would change out the springs on the oil bypass for cooler and oil filters! The spring on the oil pump as well, sense you have to pull the engine to get the oil pan off. Working at a dealer ship, had a test plate to put on the fuel injection pump test bench to check those oil cooling jets for spray pattern hitting the piston bottom, we were able to adjust them at that point. Have fun!

[@AdeptApe]

They are replacing pretty much everything on this one, including the oil pump bypass springs and plungers. I usually put the cooling jets together and make sure they flow as well before putting them back in. They are fragile little guys in such a hard environment.

[@shitindawoodsbear2798]

I remember aiming the piston cooling jets on the fuel bench..you bent them around with that goofy tool till it squirt through the target hole with the part number you were testing..haha! When I tell guys about that set up now I think they think I'm full of bologna! What dealership were you at? I still use the fuel bench now days but don't have the cooling jet set up.

[@jasonburton-j1m]

When I have been in situations where there was an egregious amount of residue stuck to the block, I use that as a springboard to have the machine shop bake the casting clean. A thorough bake job removes rust from inside the casting, as well as all of that stuff from the outside. it costs much less to have a block cleaned in that fashion then it costs the hours to manually do it. It’s followed by superior product. While the machine shop has it, it’s well worth the money to have them inspect it, including magna flux. I know that farming out work is not how you make money, but it also frees you up to do other things to make money while giving the customer a superior product. That’s just my two cents.

[@dirtfarmer7472]

That’s a good 2 cents, hope they get a chance to read your comment it might save them some $$$, they’ll like that.

[@bellabella852]

Funny thing about that pistol impact from team red, I don't know if you watch Torque Test Channel at all but I'd definitely recommend giving them a look, they did quite a few tests on that thing and it actually hits harder going forwards than reverse. It's basically designed for construction work with heavy steel!

[@brianburdine4620]

Love when a truck guy can sympathize with the equipment guys lol. Nothing I work on the pan would come off without yanking the motor. Not to mention valve cover/head access on this grinder is amazing compared to most equipment. Loaders & dozers is usually 4+ hrs to even access the valve cover.

[@butchphillips873]

Yep power screens and crushers are great for access.

[@Hybris51129]

I will admit that I would be terrified of doing any major work until after the block was cleaned to the point of being paint ready. Dust is one thing but with this stuff I could see it getting into passages, heating up under use, then cooling in a inconvenient place, and causing problems from there. Still good on the customer deciding to go the extra mile to clean and overhaul the engine.

[@snoopdogie187]

I would imagine with the cost of that machine, a good company wants to do any and all preventative maintenance.

[@jimbradd2783]

Best thing we did that stopped the cat head gasket problem, was brought the aftermarket head complete with the oring machined in the head worked great, no more head or gasket problems, and are c15 was chassis dyno checked at 1000 to crank 800 to the wheel, very reliable and fuel mileage was still decent

[@robertschemonia5617]

I am a firm believer in poking a hole in the filters too! On trucks, I have a 1" square tube thats about 4' long amd has a sharpened ⅝" bolt thats about 8" long through it. I use the leaf spring as a fulcrum to poke them open. On other stuff, I use a sharpened slag chipping hammer. MUCH less messy that way.

[@davidoneal6969]

Id get a reman short block minimum, when you start blowing head gaskets, this indicates a twisted block. You'll see when you cut counterbores, 1/2 will cut straight, 3/4 you'll have to hand cut some, and 5/6 you'll have to hand cut most of the bore to get everything straight. A twisted block happens more than you think in chipper applications.

Hey up Josh as soon as i seen this video was super interested, those chipper's only ever work hard unless there moving there track's, the lack of emissions is probably because classed as a stationery engine, really sweet to see you working on a machine rather than a truck or off road unit great video mate and so looking forward to part two

The owner is doing it right It’s cheaper to do it all when you have it out now.

[@michaelbrown6241]

The latest new C18 block for some products come from the factory with stainless liner seat and water ferrul inserts to slow up the liner recesion and ferrul seat erosion. The underlying problem though is excessive block flex under load, some machines are leaking coolant/oil externaly at less then 2000 hours, replacing head gasket and spacer plate shim alone will not fix the problem for long, always replace the head bolts. C15 C18 are the same block and have the same problem except C15 is owned by a different devision in Cat and does not get the same R & D funding as the C18, eventualy the solution for both will be the same.

[@jaydunbar7538]

IR? Fairly sure those were Milwaukee lol The 12ah battery doesn’t do more amperage it does less, if you want max output go for the 6ah. Torque test channel does full testing and breakdown of the cells to show why for those interested. The 12ah has higher mah rated cells which comes at the cost of draw rating, the 6ah is obviously the opposite so you get higher draw available for the tools that can actually use that level of power.

[@AdeptApe]

You're right, I'm not sure why I called them IR and not Milwaukee.

[@sedrickmartin5152]

So, i'm curious of the outcome of this engine teardown. Be mindful to inspect the bottom ring surface as C18 are known for having them destroyed as the liners moves. It does this because the liners are so thin compared to the C15. I just did a full one in frame on a 836H and thanks to out field machinist, we where able to do them without pulling the engine, just alot of cleaning haha

Might want to consider sending the Radiator out to have cleaned internally while you rebuild the engine. After the Rebuild that engine will make close to Factory horsepower and generate more heat than before. Spray diesel on Tar,Asphalt and it will loosen up. Old school field guys always used a tool tray to carry the basics up onto a machine so they didn't have to climb down for something somple.

Walmart (I believe) has sockets that have rounded internal lobes that contact bolt heads in the center of the flats. Originally they were patented by the Bonney (?) Corporation in 196Os. The sockets grip by attempting to remove all the corners off at the same time. They work on bolts with all the corners rounded off.

Ref emissions and why bigger engines lag in being regulated, the bigger the engine, the less they sell, and the less overall contribution is made to overall world emissions, so the regulators bias stricter regulation to the smaller more populous engine sizes. as far as I understand it - this is why on-road engines also get regulated more tightly first, because the world contribution is heavily led by cars, vs the much lower numbers of machines worldwide. there are also so many ratings, and uses for off highway, and the much harder life they get, that it takes longer to develop heavy duty versions of the technology for emissions control (I used to work for CAT.... in engine development).
