Just started with CAT this year, your videos help a lot.

outstanding .... i wish everybody's videos were as clear and businesslike

Great video. I have worked at Cat Dealer for 25years & Been rebuilding 3406B,C,E C-15, C18,3412E,C27/32. Love 3400serirs engines. Looks like I've been doing everything the same. Keep up the great work.

Gotta say Josh, probably the one and only video that explains the setup for cutting counterbores on a 3400 series. I just learned the hard way how to do it last week. Couldn't get anyone to cut them, so we ordered a Monaco tool. I won't get into the "how far too cut them" discussion, but other than the slop in the adjusting nuts, you are spot on on the setup. Also have to say I thought to use the ear plugs for gallery plugs. Might recommend, masking tape to cover the oil drain back holes...

Very nicely done! Used powered one and hand one for 47 years at a Cat dealer! Spent18 of those years doing field jobs just like this! Enjoyed the video, keep doing them!

Awesome work Josh. All your videos are well narrated and concise, I'll probably never work on this type of engine, however, as a mechanic I greatly learn and enjoy all your videos. Thank you. Jim.

I'm getting ready to do one of my 2ws engines. Haven't cut a hole in 2 years but I do my own work so this was a nice refresher for the memory before I start.

Wonderful content that helps the Cat community keep those terrific engines running.

Thank you for providing this content. It beats my math class

That Monaco counter boring tool is the best I had mine for 6 years and use the heck out of it.

I learn so much from these videos! Thank you

Can hear the baby having its own good time in the baclground :)

That's amazing, you really do great work !!!

Man ive learnt alot from your video's, and i use that knowledge in my trade. Im very grateful you share this and go into alot of depth in procedures and what tooling you use. Your easy to understand and clear. Thank you @Adept Ape!

The shop I worked in had the Kent Moore setup. Great for Cat, Cummins and Detroit. With add ons it also did the lower press fit Cummins and the bottom of the Cat blocks from erosion. Those inserts were pricey!!!! I always did 2-4-6 then 1-3-5.. A sanding block and 14 inch mill file for cleaning and de- burring. The Cummins used an insert. On most of the 855 blocks your actually cutting the insert next to each other. The Kent Moore tool was powered by a right angle driver.

Awesome information. Thanks for sharing 👍

Very informative video, you really know your stuff

Very precise work

Great video Man, good to know the new thing I never dine this before. Thanks

Nice! 2 parts and nice length!!!!

straight edge and feeler gage probing footage in this nicely done video documents deck flatness outside of bore planes--i.e.--lateral block margin--some authoritative sources also perform mid axial and diagonal gaging of deck looking for "torsades de plan"--twisting of block--a condition much more commonly found in warped cylinder heads

Excellent video, I would say basically anyone who's truck/engine you work on can breathe a sigh of relief, it'll be right. Nice work!! Can only imagine the stories them .200" shims could tell...

Fascinating video thank you!

Great work

I learn a lot from this video

Great video, very interesting

Thanks 👍 I have an old deuce and a half Hercules multi fuel engine that blew a head gasket between the 1-2 cylinders so now I know what to look for

Nice video.

Another good video once again. Crazy how many technicians I know who use die grinders to prep block decks….

Excellent

good job.

Nice job very good video

Fascinating

Thank you

great video...

very interesting!

Awesome !

very nice great and smart man

Been at a cat dealership most of my 30 years. This is exactly how I was taught. One thing I added was a suicide knob to the handle.

Have a link to the pneumatic vacuum you like to use?

Slow and steady wins the race when doing that for sure. People don't realize how much time is spent cleaning and measuring and taking notes when doing it properly.

Do you do anything to bottom ridge when counter boring. Great job on your video

I could have sworn I saw a video like this before

It seems crazy to me that you guys get this level of work, now granted our work is to turn around as many 3500s as possible for all the different FRAC companies we serve. If it needs any machine work they send the blocks off. For a bit they were even sending every 3300 out and letting the machine shops tell us if they needed any work.

Josh - I have a question - when you are setting your depth of cut on the tool do you have to account for the depth that the liner has sunk? In the one example the liner measured -.005 on the initial measurements......does this mean you would set the depth of cut to .024 instead of .029 on that particular cylinder if using the .030 shims on all six cylinders?? Thanks dude!

Hey Great video tutorial. Who sets cutting width , is there a chart or work sheet ? Thank you

That cutter seems like a nice tool for squared-away results. I wonder if they make one with a low-speed powered drive like a pipe threader has. That would be cool.

I'd solved this liner issue with a specially redesigned liner with a special chamfered sleeve with a special square seal at the top and illuminating a lower one.weve used these in bull haulers engines big stupid power 90 ,000lbs to the mat..no issues with any or the mining pistons they created with fusion welding..if only cat would listen to us they did..and now they have a redesigned water pump works great.all I have is cats,my dad had cats,my grampa had cats,my great great gramps had oxen😂🤣😁😁

What happens if you put shims with part numbers facing down? Tech who shimmed my block said to install leters facing down? Thanks alot!

So using the feeler gauge to set the spacing between the two stops, is the space your closing up by moving the bottom stop up one click. Then when you’ve done it 29 times, both stops should be touching and you can’t move anymore clicks right?

That was awesome like all your vids. Question - why do you have to cut the counterbores in the first place......just curious

What is your tolerence with the staigh edge for knowing if its surface is ok

Just can’t help but notice that water pump inlet hose just open this whole time while you were working on the engine, I’m just usually careful about getting any kind of dirt into there without noticing, but awesome job showing details of this process

What’s the labor time for a job like this? Complete Inframe.

I hope I don't have to do that anytime soon thanks for sharing...

There’s a new channel I just came across called Jim’s automotive and machine shop. He’s working on an Allis Chalmers tractor that he just rebuilt. It launched the oil fill plug across the field and had coolant under the valve cover. Seemed like a liner issue to me but there is no talk of it in the comment section and and no mention on the videos and they installed the liners by hand with no tool to set them in straight. What’s your thoughts?

A lot of the mystery of liner protrusion has been answered

You heard of ZK Mastertech? Would be interesting if you go the same route with video style or something. You both show what goes on in your careers, but you may not want to go that far into it like zk does.

03:03 Wow that's a narrow area for the liner to sit! If the liner had more area to sit on do you think it'd wear less or not at all? Are cylinder blocks deliberately designed with extra thickness on top to accommodate resurfacing (re-leveling)? I have so many questions lol.

Ipd has solved cats sunk liner issues with a redesigned slefve with a speacial square chamfered o ring

Just read a Cummins ISX forum the other day discussing dropped liners and how a "counter bore" must be cut. I said: "What the hell is a counter bore..??!!" Now, after watching this video, I know.

Hey mate , what size brake booster diaphragm do you use??

What caused the liners to sink?

Is your headlamp a Nitecore brand?😁

I know your a cat guy so am I Josh.. but IPD solved this liner issue on cats by redesigning a better liner with a special square top seal and now have another option available thats even better.and trust me 75 cattle haulers here running them along with the better aftermarket head have had zero issues..

I use a die grinder to get off the heavy-duty stuff with a very light cookie disc then I go on the doing my scraping and sanding at no point do I ever cut into the deck with a cookie you're asking for problems with the new gasket it'll never seal-rite or if it does it's not going to last very long if there's not a lot of gasket material stuck to the head sometimes I just use a simple wire wheel to break down all the heavy stuff and then again do my scraping and sanding

what if the spacer is installed upside down?

I have a completely unrelated question to this video and I was wondering if you could please help? I am a heavy diesel apprentice and I've asked all my trainers aswell as my supervisor and no one knows the answer. I've also searched Google relentlessly but still come up empty handed. #pleasehelp

Anyone have a good price on shims for the 3406b ? I need six .034" 6i4362 and six .061" 6i4363

Was wondering why sleeves needed shims, now I know.

😎👍

What happened to alien technology carbide edge tool?

💯👍

What causes a liner to drop?

I have never use that style of tool. Our tool you use a electric drill and takes about thirty seconds to cut the hole once set up. I put two plugs in the block, one at the lower deck and one at the top. Since a drill is used on our type of machine the metal expels out. So I use masking tape and tape the top deck closed to prevent any metal from getting into other cylinders. When I set my depth, I measure all of my shims and use the thinnest one. They are not always the same and I place my shims in order from thinnest to thickest unless my depth is not the same on all cylinders. I place my shim in the tool and measure the gap between the bit and the block. I locate the best place to make this reading. Naturally you don't want to use a low spot to do this. If a spot is not available, I slide my bit out and get a section where the flange is not setting on. The pitted side of the liner, the exhaust side in this case. Is called the high load side. Most of your problems will be on that side, cavitation erosion, piston slap, driving the liner into the lower deck wearing it out. Basically the liner receives the shock load and vibration resonates from that side.

Don't turn backwards, can break, chip, and does dull the carbide bit.

Use thread chaser not a tap to clean threads

Why do the protrusion specs change to .0035 after the shims are added?

I would just go ahead and get a rebuild

I emailed you boss

Hi

80$ each

I thought you hated air ratchets 😉

The only people that use this tool are truck mechanics, to do the job correctly pull the engine out do upper and lowers and water ferrals then the engine will do another life any thing else is a short term repair. We do 100s of blocks a year.

I just looked up that cuter $2300 seems a little pricey when you only have and plan on having one truck. Lol

Counter bore... Why everyone doesn't have a 3406b in their classics.. Super expensive and time consuming...

First!

All this to change a fuse? Just kidding!, the guys in Pakistan would have just rolled it in the dirt and hit it with a rock. Slap back together and send it out. Only to come back next week, but that's called "repeat business"... Josh, you guys fix it too good, no repeat business

Liner protrusion isn't that when the engine get too many little blue pills in the radiator?😎

I always just buff the hell out of the spacer plate, problem solved

If they installed the shims at the factory then you would be out of a job. Too bad the liners sink all the time and blow those head gaskets. it could be fixed but that would cost more money.

If you’re receiving gifts in exchange for product placement, you need to clearly disclose it. The FTC has been cracking down on undisclosed sponsorships.

where do you see yourself in five years?
