When u overhaul this family of engines liner lip must make 100% contact on deck so if it doesn't counterbore it and try to get all protrusions within a thou .when installing liners soak filler bands for about 20 minutes in engine oil .manual says 5 mins but I have had them in oiluch longer and they are still not swollen too much to install .lubricate orings well fill grooves with lubricant and push in gently .torque head to specs and use manual specified lubricant on bolt threads and note well all bolt holes need to be cleaned well so no thread binding can occur .I always ran a tap down EVERY HEADBOLT HOLE IN BLOCK EVERY ENGINE. 1 tight bolt hole can cause a problem later .Anyway 3406 lubricant was 5p copperkote quoted in manual don't add extra torque when tensioning head ..There was a lot of cracked liners years back and I used workshop manual as bible and never had this happen .lol .basic sense .I just had 2 bobs worth here for old times sake .I did the odd Cat engine long ago .and insisted on the manual being followed in the workshop .Using other lubricants on threads of head bolts and giving 10% extra on torque wrench can lead to fuck ups . Obey the correct manual relating to the engine you are doing is my golden rule

[@kylew657]

Hey Josh. Thanks for helping me and my buddy out. You recently sent him a manual for a c-15(I think). We are overhauling it, leaking liner o-ring on cylinder 1.

[@ianloy1854]

The liners are exactly what they should look like - the same as the day they went in. With Long Life Coolants you should never see any rust or cavitation these days (should never have seen significant cavitation. 3306/3406/C15/18/3500 are all old style liner designs. They had improved designs in having the spacer plate so to remove the counterbore for the liner lip. The liner the is supported down near the bottom of the liner. Newer design 3176/C10/11/12/13/C175 (Series 60) are mid supported liners. They have no flange at the top and they rest about midway down the liner (hence the name) at about where the piston changes direction. This means the liner is thicker than otherwise and the combustion part of the liner is supported top and bottom. A much better system and one that rarely if ever needs to have counterbores done.

[@jkontons6340]

My personal preference is to put main bearings in before cutting the block. For one to make sure the crank is in good shape and also I feel better about no chance of getting metal in them because they are already in and toqued.

[@UrsulavonB]

Shavings cen still ingress because of the large crank radius.

[@johnstuart3851]

Piston rings rotate in the grooves when the engine is running. (Unpinned 4 cycle,) The end gaps occasionally align, but not for long. It is abnormal if the rings get stuck in the grooves and stop rotating during operation. At maximum engine speed, the rings rotate +/- ~ 6 RPM according to Ricardo.

[@erikegeland9853]

Thanks for the video! Not surprising the sunk liners. We see it quite often on c18 and c32 since they share the same liner. Since they updated them back in 2019 or so, just chew up block counter bores. Once you counter bore them, they don't seem to have an issue again. I had to cut a whole alittle over .100" to get it to finally clean up. Plus on the c32 they wear out the lower receivers usuallyhave to insert them at everyrebuild to. Take care

[@vandall2518]

@AdeptApe, Josh, the 3/4” Milwaukee is a lot better than the 1” pistol grip. If you put the 12.0 amp battery and adjust the setting on the app, for the 3/4”, it’s the same as the 1”. Food for thought.

[@deanriley5690]

And the makita 40v is even better😊

[@1320pass]

Nice c-bore cutter Josh, wow. 😍I want one and I'm not even a big truck mechanic.

[@kanemcdougall8337]

Put a bigger battery in your impact, makes a fair difference in the Milwaukee guns

[@seananderson5601]

Good point on the ring gap. The reason they want us to separate ring gaps is strictly for break in. Align all rings and compression will be the same.

[@crandonborth]

If you wanna really good 1" handheld impact go with the 40V Makia XGT... i have used both and its not even close to the same. That Milwaukee you have makes more power in forward where as the Makia makes its power in reverse which is personally where i prefer it.

[@DanWoelders-fd5zd]

Those 40 volt are monsters. Soooo bloody expensive tho

[@crandonborth]

@@DanWoelders-fd5zd Yeah they are pricy but it’s not much different in the terms compared to the 1” Milwaukee he already has.

[@Arnthorg]

wondering if you could make an adapter for a battery drill to turn the counterbore cutter, seems like it would make for a better time, if careful at least heh

[@douglasmayherjr.5733]

I got one of the new Milwaukee 1/2” High Torque Impacts with the Forge Batteries for some stubborn bolts on a job 5/8” and up. Oh my gosh, it is an absolute monster and will snap off a grade 5 5/8” bolt way to easily. I have a lot of red tools, some are worth the hype, some are not. That one is definitely worth the hype. The Forge Batteries are impressive in whatever tool I use them in. Extremely long runtimes and compact size. I hear they have even better tech on the way. Those sleeves look thin, better heat transfer. Thanks for the Videos, Josh. Looking forward to the next video on the C18.

[@oldcatmech]

The exhaust valves are to that side of the cylinder, so the liner expands ans contract the most on that side of the cylinder! Also when the engine stops air can come back from the exhaust to cool the open exhaust port and the liner cools and shrinks, over time it wears the block. The stainless steal shim-inserts spread the cooling area out from under the liner lessening this effect on the block area! Watch on the engines you find the erosion, and it is in the exhaust valve side of the cylinder!

[@AdeptApe]

You are correct in that it is usually on the exhaust valve side of the liner, never really thought it could have anything to do with the valves, you might be onto something.

Hey Josh, ever notice that the head gasket fails the most on number four cylinder on in-line six cylinder engines. Also the coolant use to enter on number four and Cat changed it to the rear now. Had one come in a few years ago, that entered in number four. The customer used the block heater plug and put a hose to the rear as well.

[@UrsulavonB]

Adaptape...if you can find a Autocrane electric crane, they work great floor mounted in the shop for lifting, turning engines, trans, etc. Torquing mains, rods with the block laying on it's side is easier, faster and you can see 👀 better.

Relating to you comment about liners not being easy to pull, we had a series 60 detroit that bound up on of the seals. Welded a bar in and tried to pull it out with the crane, ended up lifting the front of truck off the ground by the liner. Ended up having to remove the engine and get the liner out with the press

[@AdeptApe]

Haven't had one that tough, but have had them where the pack puller wouldn't pull them out and you have to pull the pistons and then use the puller assembly. Strange that the little seal you can probably bite in half with your teeth will bind that liner in there so tight.

[@jonathancunningham2686]

The 14 L 60 series big rod end won't fit through the liner. The pack puller wouldn't grab the liner so we ended up putting a sheet of heavy grit sandpaper around the tool to get them out.

On an F150 I did front struts on, I think it was a 2004-2008 body style, it had a large bolt and captured nut. Torque spec on that was 450ft/lbs. Thankfully my shop has a OTC 3/4 torque wrench that goes up to 600ft/lbs. Even with me kind of hanging on, I could barely get it to click, but was able to do it. Kind of scrawny at 5'9 and 170lbs.

[@elroyelblander6277]

👍👍like anyone cares, but I've deduced from various sources,that the liner issues that engine and others can potentially have is very likely from the low rod/ stroke ratio ...long stroke with a connecting rod that is too short..it side load's the piston/ liner to the passenger side.. causing it to vibrate/ wear more so that direction.... perhaps that isn't the entire story and i know someone else out there knows more on the subject....it doesn't really matter...great engine's either way... thanks for another video 👍👊

As far as Milwaukee impacts rank, Torque Test Channel has "Dyno chart of every Milwaukee Fuel Impact". The 1" is basically same as 1/2 or 3/4 as far as removal torque. 1" is better at tightening though. There is newer impacts since this video, not on graph.

[@MDLyles33]

Off topic a little but you are my go to so… I am doing injector seals in a 97 Ford L8501 Dump truck with a 3126. My issue is, this 3126 has the injectors that require me to remove the rockers and I wasn’t aware that there are cups between the pushrod and rockers. I did manage to not drop them but somewhere between my work bench and the truck, I’ve lost 1 of them. So I have 2 questions. 1. What does cat call them in case I have to order? 2. For peace of mind, I ran my bore scope down in the hole and while I didn’t see anything, theoretically, could one of these make it all the way to the pan or if not, how far could it go? Sorry for the long post.

[@JewsRock-ILJ]

What do you think of intake manifold water injection for turbo diesel? I heard it keeps the valves clean and helps cool the engine down more efficiently while allowing more reliable boost and fuel efficiency. I bet it would prevent dpf blockages and egr carbon buildup and or blockages.

[@dcviper985]
