    Forgot to mention it, but these are thin walled chrome-plated liners on this engine and are not meant to be re-honed.

    • @ChuckThree
      @ChuckThree 10 месяцев назад +6

      Well that sucks. I know there are specialists that can machine out plasma arc transfer (harder than chrome lined…?) cylinder liners on certain automotive examples (ie. Nissan GTR R35, Ford GT500 5.4, Ford Gen 3 Coyote, etc). *BUT* I’m fairly certain those aren’t done on an individual job basis. And are small batch machining operations using a core exchange program.
      Sooo probably not applicable and almost certainly not financially logical in your case.

    Cams and tappits are case hardened so when they start to show signs of wear they must all be replaced. New tappits on old cam lobes will destroy the lobes. I recommend replacing the cam and tappits as a set.

      Also, rebuild the injection pump. I didn't catch if you where going to or not.
      Do not just have redone injectors, what went through the injectors had to go through the pump first. The crap that tore up the injector tips, did a number on the pump plungers and bores.
      Best wishes from the far North.

      Why not have them reground then? They all looked to be in good enough shape that I’d think it would be worth a shot for the machine shop to try it. If there was damage then ya toss them. But the case hardening, as shallow as it is, is still deep enough to be ground once.

    • @SuperSecretSquirell
      @SuperSecretSquirell 10 месяцев назад +7

      @@Mad.Man.Marine the lobes are already under spec, so grinding them is just going to make them even smaller. Plus, who knows how much of the case hardening is left after the wear. Could get into the "soft" core and things will wear down really fast and trash the engine.

      When you grind metal it heats it up and removes the hardening... you would have to re-harden all the lifters and the cam lobes and bearing surfaces.This would require special equipment that would cost many times what a new cam and lifter set would cost.@@Mad.Man.Marine

  • @danielyoder5928

    Matt, things did go right. The oil analysis came back showing possible problems , you investigated the possible instead of ignoring it. Saved the block. Crank and other high dollar items which would have been destroyed if that piston had let go. Replace the camshaft and lifters cheaper now then down the road. You are too far into it not to replace it.

  • @ronaldheit196
    @ronaldheit196 10 месяцев назад +40

    Well Matt, consider yourself lucky that cracked piston didn't grenade itself after you bought it.
    I've seen that on some engines where a cracked piston was the culprit in destroying a block itself.
    Not to mention the piston rod, main journals and pretty much the entire engine.
    You're definitely developing into a very good diesel mechanic and old excavation equipment refurbisher.
    Can't wait for the next episode and see how you're doing.
    Especially how the block turns out.

    Bronze = valve guides. usually. Babbitt bearings = journals, rods, usually tin/lead/copper alloy, could be a source of "bronze" in oil analysis.
    Oil analysis is good if repeated on a periodic interval. Waiting 10 years and then looking wont tell you anything useful. Your best bet is to do what you're doing.. tear down, inspect, Replace as needed (IRAN).
    carry on! :)

    Hi Matt, great video as usual, re your timing marks on your left you had two teath marked C (creating a valley) and on the right you had one tooth marked C, the one tooth fits between or in the valley created by the two C's, This may sound strange, but every full 360deg rotation doesn't mean that all your marks will line up, I've just rebuild my DB990 and it took 17 full rotations to realign the marks, which is why they tell you once you've timed it in the rebuild do not rotated it untill you've got it all back together.

    In my humble opinion, it is obvious that this machine has NEVER had any serious effort at preventative maintenance. On systems that I've managed, the numbers in the analysis are distorted as contaminants accumulate instead of being flushed out by filter and fluid changes. I'll bet that someone bought this machine used and never did anything but crank it up and go to work. That's why so many good machines end up sitting abandoned. Trends in the measurements will reveal what's going to happen in the long and short run. You have a fan club here in Georgia.

    The engine is from a standing machine, unlike a road going machine like a truck, so you don't need to give it a near full overhaul. Piston #1 and its sleeve need renewing, sleeve #2, 3, and 4 would do with just a light hone. And renew all the rings, and this should give a balanced compression on all cylinders. The cam bearings, if cheap renew all otherwise just a polish on the rough one(s). The engine will get new, good oil, so the mating parts will just bed in with time.

    One of my tasks as a QA guy in the engine plant of a large car company in the long distant past was checking the torque to yield machines were doing the job to spec. I had to take new fasteners, center drill both ends and measure the length with a ball end mike then run the fastener through the machine cycle and measure again to check the yield (stretch) using a new fastener for each spindle.
    I doubt you will pick it up with a check on the shank diam with a mike.
    When fasteners have been torqued to yield the material has been structurally changed by being plasticised. They should never be reused.

    This thing will be running like a brand new rig when you get done with it. Really enjoying the video man. After this project, you need a really good dump truck and heavy duty trailer to haul this stuff around.

    Fellow hillbilly pay the price once. Get new pistons rings all berings tappets pump rebuild everything. One old part can turn a rebuild into 2 disastrous rebuilds and double the work. 👍respect

    Keep in mind the cam only turns at half the crankshaft. Would probably go a long time yet as it is.
    Idler gear is probably a non hunting gearset so marks will likely line back up after so many revolutions. You’re balancing budget vs what absolutely needs to be replaced and its never an easy call. Myself Id probably change all 4 pistons for peace of mind.

    • @erik_dk842

      Non-hunting = having a prime number a teeth, so the same pair of teet only engage every N1times N2 revolutions , for instance 37x41=1547 revolutions.

    If your going to replace 1 piston for a crack,replace all would be best thing to do, also those are full floating pins. rod bushing “worn” piston is worn. Replace camshaft and lifters Great job as always ps have the injector pump gone through

    Another awesome Matt. There are some excellent comments here on the specifics of rebuilding. I suspect you will take them all in. I would tend to heed the warning/caution about that “chinesium” turbo cartridge (somebody mentioned it being a Subaru turbo, so probably easy to find a better quality one).
    Great video,
    Thank you sir.

    The usual source of water in tanks is caused by leaving fuel tanks low at the end of the day. The fuel gets hot when running. At the end of the day it cools off and sucks in air from outside. That air can have quite high moisture levels which accumulate over time. On larger bulk tanks you should put on a water vapour filter and on the machine itself just fill the tank at the end of the day.
    Another source used to be drum fuel. all ways store drums standing up, angled with a board or some such thing and always have the bungs at 3 and 9 oclock so rain water buildup can not be sucked in.

    i think if you change your camshaft, you should go with new lifters. concerning the crank, i can tell it is a forged unit. still, it might make sense to have it magnafluxed to check for cracks. i would also suggest that all the connecting rods should be sent to the machine shop to be checked and resized with new sleeves installed, and purchase new rod pins as well. on the flip side, have you considered purchasing another used motor, as that might be the cheaper route?

    definitely would recommend replacing the stretch head bolts. if they recommend it do it! not just one or two all of them! It's not a length problem,it's a stress thing with the bolts. everyone I ever heard of that did not replace the head bolts with new stretch bolts regretted it.

    Yes they have chrome rings. The liners are very thin and are dry liners. If you look in the manual, they have a list in the back for the tools for rebuilding. Is the machine shop doing the liners? We used to put the liners in the freezer before we installed them. The liner diameters are measured in half thousandths (.0004") First you measure the bore with the liner removed, then you calculate what liner is needed. At one time, Isuzu used to print the bore size on the top of the block. The chrome on the liners wears out first. If you examine the top of the liner where you will get a ridge, you may notice grey spots. Those grey spots are where the chrome has worn off and the steel underneath is showing through. You will need a special tool to get the liners out. Triple check the tool as you pull the liner to be sure it is seated properly against the edge of the liner. I have seen more than one block ruined by not having the puller tool installed incorrectly. These days they are making a generic replacement liner: one size fits all. The original liners were an improvement as the close fit allowed for better heat tranfer into the water jacket.
