Excavator Repair: Swing Bearing, Injectors, Injection Pump, Oil Cooler.

Happy belated 4th of July! We are making some good progress on The Beast. Big thanks to Area Diesel Service for helping me out. They are a great resource to have for a guy like me who is always working on unfamiliar engines for the first time, trying to figure them out. I hope everybody has an awesome weekend! Many people wondered where I got the plugs: amzn.to/3xJzXak. I also forgot to mention that before pulling the swing bearing out all the hydraulic lines between the house and the undercarriage would have to be disconnected. Cheers!

Ya know, work doesn't bother me, I can sit here and watch you work for hours! :}

I bet it will take a few days to get the smile off your face after finding swing bearing problem good job

This stuff beats the hell out of anything on tv or at the movies!!!❤

I see FarmCraft101. I watch. Cannot get enough of your videos. Your approach to fixing things has enspired me many times over. Do not stop what you are doing. You have the right recipe.

A quick and dirty trick with copper washers, is to heat them to cherry red with a torch, which will anneal the copper, making it soft again and allow it to seal better.

Your level of patience is staggering, the removal of those (2) nuts behind the injector pump, impressive.

Hi! Each sleeve/cylinder and it's head are all separate from each other so if one fails, you don't need to rebuild the whole engine unless it is worn out of course. All cylinders are held down by four trough bolts and if you have ever taken a cylinder off from a air cooled motorbike, it is exactly the same concept. What we usually do is we take the oil pan off, unbolt the conrod, take off the valve cover and the rockers. Take off the plugs for the trough bolts and then after taking off the bolts, take off the bolts/studs for the intake and exhaust manifolds for that cylinder and then the whole assembly with the conrod, piston, liner comes right off. This will save money a lot. And if you need to do the whole engine, you don't need to waste money machining cylinder heads. Even if one head is warped, what I did I just used valve grinding compound between the liner and the head and just rotated the liner with a drill (using some thread bar and wood blocks) and just lapped the surfaces flat again. Heads can be bought separately as well and usually cost so little that no valvejob is really worth the effort, but can still be done if needed so. This engine can also be rebuilt without even touching the bottom end. Start taking each cylinder apart from the alternator end and put things back in that same order. Pistons can be taken off leaving the conrods on the crank. At this point before just putting everything back together buy a lot of thin shims and put them between the block and the sleeve. When it is time to check the piston to valve clearance (1-1,2mm), I used solder wire trough the injector hole, you can just clip off shims until you get to wanted height. If you forgot the shims, you can also buy different thickness gaskets to do the same job. I have done both methods :D It is extremely well thought out engine and very reliable. Maybe I should stop talking about it for now :D EDIT: When you are putting back the injector make sure you have the correct washer for that job! Those are aluminium heads so if injectors leak you can't just torque it down more, it will crack. Many people use copper washer, but you need to inspect a few times after installation that you won't see a black tar coming trough the cylinder fins on the exhaust side. These engines can be used with a copper washer, but they make this sort of "cork / metal cap" washer for this exact engine. Just make sure those injectors won't slowly leak. The tar is next to impossible to get off. EDIT2: Use a brass end wire wheel to clean the injector holes :D

The brake "fails safe" so if power is lost it engages. Electrical connection powers brake off, no electrical connection, brake engages. Good job tracing the problem!

I think Farmcraft 101 is my favorite of all you tubes.....Jon does such a good job and always makes things interesting.

Always learn at least one thing on every one of your videos. Thanks for letting us watch over your shoulder.

Your vast knowledge of mechanics leaves me in awe.

I'm an inspiring to be agricultural mechanic myself at only 17, and always find troubleshooting annoying and just think 'oh it could be this' and start to take stuff off. Through watching many many of your videos now, I've gotten to understand the importance of it and how it can make your life so much easier to identifying a problem. Definitely a talent troubleshooting is but I would love to learn it as a skill. I also am amazed with your patience, it is next level and will have to learn that instead of grabbing the hammer and use brute force. These videos are great to watch and put a smile on my face with all the jokes and come to appreciate the time and effort it takes editing and preping these videos, it doesn't go unnoticed. Stay happy and healthy Jon!

What a great discovery about the swing brake 👍 Could have been money down the drain buying a replacement bearing when it's working just fine

This has become my favorite channel, only because your way of clearly explaining and showing us the actual repair. But please change the busted glass as soon as possible and show us how you do it.

And that's why troubleshooting is so important. How much money and time did you save by exploring the electrical issues before attacking the swing bearing mechanically? Always impressed by your troubleshooting.

I really enjoy your longer videos John, I do also appreciate how long it must take to edit and actually film them. Keep up the great work. I watch every video you post :)

A warm thanks from Tokyo for sharing Jon. Totally enjoy watching each episode of the “Beast’s” rebuild journey. Your mechanical/electrical knowledge, diligent problem solving analysis, persistence in difficult situations and your resourcefulness in “thinking outside the box “ are truly inspiring. Also, your timely injection of humor during difficult situations makes for a very enjoyable viewing experience. Eagerly awaiting continuing episodes of this fascinating rebuild. Cheers!

RTFM repairs are the best ones

I'm kinda impressed with your collection of rubber plugs, and the fact that you use them.
