What Is Liner Projection? What Is Liner Protrusion? What Are Counter Bores? 

This is the exact stage I am at now with my western star rebuild. I am currently doing a inframe on a Detroit 14 liter before I pour money into the interior and paint. This is the only part of the build I have to sub out. I called a few machine shops and dealers to see who will come to me and do this. Quotes range from 200-250 per hole plus 150 road call plus 140 per hour. 1500-2500. Cutting these blocks is not cheap but one of the most important things on a rebuild. Thanks for sharing and explaining.

When I was learning Detroits I learned about this very thing....Great explanation Josh I hope this helps someone

I'm always waiting for the next video... I have a 3406E 1LW and I like to watch all your videos and learn... keep going

All of your videos are helpful. I know they have helped me out thank you for the videos

Thank you i have watched lots of videos where everybody shows liner protrusion but not how its fixed if it was wrong just a look its right and build thank you

Strait to the point simple easy to listen too showing all the tools and measurements thanks very much 😎😎

Great video! Love your channel. I'm an apprentice and your channel has helped me a lot

Very good video as always You are a good man and an exelent mechanic

As always, great video. Kudos to you Mr. Ape.

good video , pretty much any cat getting an inframe will need this done especially on 3406 models

I'm in the ThinkBIG program with Finning in Canada and are learning about engines and fuel systems riggt now, so THANK YOU for the help!!! Please continue with videos like this for guys like me in school trying to get a better understanding!! Any chance of hydraulic systems videos?

Very informative Thank you

Hey man love your videos very helpful. Can you do a video on a runway engine

thank you very much

Excellent, my man!

Josh great videos. I have a quick question. Should I be checking longer protrusion Everytime I pull a head? And if it's bad, did my head gasket job just turn into an in-frame?

I’ve been cutting counters on all wet sleeved engines for over 20 years.....

I've seen all your videos You are awesome

Why do the 3400 series engines always want to sink in just one corner? I’ve seen it way more often than an “evenly sunk” liner. 3406, 3408, 3412, c15-18, c27 and c32 all seem to like to do that more than others. I also work for a cat dealer on heavy equipment in the field , and for a few years I worked in our rebuild center building engines. No one has ever had a good answer to that for me, I haven’t found one either. I also get asked this question, and all I can say to them is I wonder the same thing

what causes liner to drop and how to use shims to solve this problem?

What town do you work out of the name of the company I enjoyed this video again medicine man

where does one get the special bolts to hold the spacer plate down while checking linear protrusion?

Check out IPD parts, they have a good video explaining a lot about liner protrusion and how they drop.When I was at the dealership I wanted to cut the blocks to get a better lasting repair, but they said as long as its in spec don't cut it. engine would make it about a year before the head gasket would fail. the few I did cut never had an issue. Good video J.

is that sheet from the CAT SIS? the liner measurements?

Why is it always 5 and 6 on c15 cats it seems like?

Will you put the space shim when checking the liner protrusion

Hahaha love the crickets...

do you know cats procedure for reusing liner shims I cant find anything about shims in the manual thanks

Very informative video. The cylinder caps in that engine are a cool piece of kit to protect the crank from shavings, are they a CAT only kit ?

What engine block are you working on

Hey adept! A 3116 cat engine on a truck works fine, but when its cruising on a highway, hot burning red flames exit from the exhaust and the turbo turbine shell housi g turns very btight red, changed turbo, pistons, injectors, no change. Any help??

I'm curious to know what your daily driver is.

nice info do you see liner issues with c13 lee?

After I do the cutting how long can I run the engine without having trouble again please let me know asap thank you and very informative video.

If you bought a motor for a cargo truck, which cat model would you buy? Thanks for your good videos

I’m replacing 2 liners do I need to replace all 6 ?

Hey josh, first off love your channel and your in depth info you provide. Second, I had a question about what pitch the small head bolts to torque spacerplate are? I found the p/n on a soft washers but no numbers on the bolts. Thanks again

I need your advice forums are not helping. I know you dont work on detroit but i need your input please. I got a 12.7 series 60 no egr last week my turbo started failing smoke out of exhaust at idle i replaced with a new 171701 borg warner. 2 days after i parked to unload a load and saw that the whole engine driver side was covered in oil. I took it in they cleaned it test drove it and all they could see was small amount of oil what it looked came from intake manifold and that my cam seals are shot. Their explanation was either cam seals are leaking bad under load or that when my turbo failed oil went in to intake and blew out under heavy load. But i only saw oil in the back of the turbo hot side not in the cold side. What do you think about this they said truck runs and sounds good which it does i was afraid of Headgasket no loss of power no noise no overheating

I just bought a Truck and it has compression in the coolant. My Truck is in the shop for check up and probably getting counterbores. Can they check protrusion to make sure it needs counter bores or there is no other way to check counter bores other then remove liners ?

Any chance you can put up a link to get a protrusion worksheet?

How tight do you tighten the hold down bolts when you check the Protrusion

Hello Josh! Thank you for the great video. I still have doubts of how many thou the shim has to stick out from the block when it was cut for shims. I don't think I understood or missed it. Is it .0035- .006 higher then the block? Thank you!

Hey Josh I love all your videos and find them very helpful and informative. I have a quick question about C-15 liner protrusion. I just had to replace the entire head with a brand new one due to an exhaust valve failure and I was wondering if this is something I have to check before installing the new head with new gaskets? I never messed with any of the liners or pistons.

What made you choose Caterpillar over other diesel manufacturers?

I believe you said dodo sir! LOL

I have question for you, to check the liner protusion i also need to put the gasket below the plate ? That's the right thing to do ?

Do you think a 7.3 L International V8 is a good diesel engine.

How much cat technician can change just to fix you liner protrusion? And then my mecanic finish the head gasket work

Hey Josh how you doing,do you have a email a kind have a question about another subject thanks a lot.

Hey Mr. Adept, you've been very helpful! I've bugged you with a few questions and I've now got another. I've got an 05 C15 I bought recently and I thought the previous owner had it turned to 550 but it sure doesn't seem like it. I had it at cat a couple weeks ago hooked to Cat ET for a different problem and I forgot to ask what it was actually rated at. Is that something saved in the computer where I could just call up and ask with my engine S/N or would I have to go back and have it hooked up again for them to tell me? Thanks!

Nice video man 👍🏻. Question: what do you recommend for the bottom seals on a wet liner (3406B) . the OEM says soap but it’s hard to know what soap is not going to corrode . What do you think about using CAT rubber lubricant on the o-rings ? Cheers from Australia

Hey josh , got my 6nz pulled down due to head gasket . Checking liner protrusion and this motor has 1.4 million and 300k on platinum kit . Block is cut and shimmed. Is cutting the block a 1 time fix ? Or have you had issues after its been shimmed and sink a liner . Replace the shims ? Or is it rarely an issue after the cut ? Also have you heard of Indian head shelac on block and shim for under spacer for water sleeves ? Btw this burnt out the back side of 2nd hole not bad but enough to bubble in rad . Could it push to liner seals ? Tia

What brand is that counter bore cutter and do you know anyone with any pre owned cat or detroit tools for sale?

Hey Josh long time watcher of your videos in which are greatly appreciated, I'm working on a in -frame C-15 accert rebuild when checking liner protrusion are you pre-installing the lower gasket with the spacer plate when measuring protrusion

is there a generic Liner Puller tool that will work with the c13?

Does c7 have liner protrution??

I wish I would have watched this video before I assembled my engine...

I'm currently in school to be a diesel mechanic. Random question, how many engine rebuilds have you done due to a diesel engine runaway?

My truck is in the shop now getting an inframe because of this exact problem. Head gasket went out in April. Coolant was pressurized on a Detroit 14l 2007. Isolated the compressor and EGR and still had pressure. Bought a 40$ head test Dildo looking tool (I call it a dildo cause you know your fuked when that goes in your truck LOL) And sure enough it blew bubbles and also turned green indicating combustion in the coolant. I removed the surge tank cap off and drove it from texas to Oregon like that while empty. Made sure it always had coolant and also didnt heat up. A hole in the wall shop said block and liners are fine and installed a head gasket. 30k miles Nov comes around and guess what? It was pressurizing the coolant again. Exact same problem. Lucky I only had to make it 800 miles to the house. Removed surge tank cap again and limed it home. I took a ph video. DM me and Ill send it to you. sprayed some light coolant but never hit the low coolant buzzard the whole way home. I stopped about every 200 miles and checked coolant. Had to ad in the morning about half gallon. But I think thats cause it got cold and contracted. Vs when its hot it expands and hit the coolant sensor. Decided the dealer is the place to take it to this time. They called and said head is good but liner fell. I went to the dealer and looked at the head gasket that was removed at it was burned and cracked in the same spot as the previous one.. The first shop didnt see this video or understand the concept. Thus here I am paying for the job to get redone and now I am also getting a inframe done. Which I should of had done the first time. Im glad I didnt have that shop do it. Nothing like spending 16k for a inframe at freightliner dealer to make one feel like "badassbillybigrigger" Or brokedickownerop. Thanks for sharing. Good job on the pics and video showing the tool needed. It helps me understand what happend and how the dealer fixed it. they charged 1300 to cut the block.

Just did n inframe on an N14 an didnt get the liners perfect....well guess what...

What is meant by a "marine cam" and why do people use them

Dose anyone have a counterbore tool for sale?

Install piston rings

Don't worry about the nuke being false for me! Haha, The way My engines will run, in each cylinder, EVERY ATOM, will be SPLIT. Don't worry about my exhaust temps, I got some cool tricks! But one thing I can't stop is when that exhaust valve has to open to let it alll out... Gotta send it to space!

Crickets were a funny touch. But I could barely hear them

My truck is the year before the Powerstroke but it has a turbo

Sub titulos en español por favor 🙏

The hand tool is much more accurate than the hydraulic tool.......and the 30 shim is way to expensive ......there are steel alloy shims that are much more cost effective....cat pt#5s8142

Does adep ape have a email address My c15 is FU

You contact work

is 25 too old to start as a diesel tech

In frame is never completely accurate. Never as accurate as out of frame.
