Same as the Genius Girl who is fixing every broken motor in China, the paint is the giveaway

[@kenc3288]

Not the same, that so called genius girl never grinds crankshafts or replaces bearings, piston rings or seals, never checks bore diameters or hone cross hatching. Never checks crank journals for tolerance or condition. Her projects are just rudimentary clean and paint. She may amaze the unitiated but her work is just a rough patch up job and will not give satisfactory performance.

That's a mini excavator. It's far from a giant. No torque wrench in site & reused parts in the engine is just asking for trouble. Looks like a fun restoration though.

You need to buy a torque wrench one day. I hope you made a big profit when you sold it, for all the hard work you have done.

What's amazing is that not one cylinder needed a new rod, barrel or pin rebuild, nothing on the machine was seized, all it needed was to be disassembled, cleaned and painted, NO PROBLEM, RIGHT!!!

The work was impressive. This, however, was not a solo job. Someone inventoried and documented the parts, someone did the lathe work, someone did the welding and metal fab. Two people I believe the hydraulic lines. his was good work but it was definitely a team effort.

[@mothballenema9595]

Considering the amount of work that was put into this, I’m confused as to why pins and bushings weren’t replaced.

[@top_dawg_toby]

Finally someone who can saw that. Did u see the bucket needing to be reskinned? and the main bearing between the tracks in the cab having a quarter inch of play? And the head gasket not doing its job when he started it, cuz he took a angle grinder to the milled mating surface… and he has a mill

[@deweylee2449]

I don't know what country this gentleman resides in but that is besides the point. Ive seen alot of videos of these sorts and this just shows that people everywhere are not pulling apart something like in the states to collect or refurbish forever. They take things apart and repair out of nessasaty. This is why other countries that are not as fortunate as say the US have more skilled labor in many aspects. People should take note and think twice about throwing away that lawn mower or weed eater away so quickly. Maybe box it up and send it to these people. Maybe the landfills won't fill up so quickly.

[@mickdu2515]

Here! Here! You say this again.

[@Timothy-lb2vr]

The USA went through the era that is depicted in this video back in the twenties and thirties. Minus the power tools as there was no electric power. My grand father immigrated from Italy in 1898 looking for a better life and more opportunity. He found it but it wasn’t handed to him. He was a share cropper in the rural areas around Verona Italy. He farmed some here in the US and eventually became a plumber. He said the USA was “paradisio”. He and his fellow immigrants did well here in the US. Raising large families, starting businesses,buying and selling land, raising their children who also did fine. One of my aunts actually became quite wealthy in the scrap business. The USA is all about opportunities for anyone and everyone.

It's a show why complain

[@WZDIESEL]

I’m so confused right now and have to think this is a joke but they painted most things fixed the things that don’t matter like the seat and the body but forgot about things like the track adjusters the tracks actually the whole undercarriage, as far as I can tell they didn’t put new pins or bushings in anything they didn’t even put teeth on the bucket! For those who don’t know those are the shanks that the teeth are attached to and they struck an arc many times to cold weld on some little plates to the sides of the bucket that probably fell off in the first five minutes. I can see light coming through the bottom of the bucket everywhere and then they painted it too? Why? Life in BFE I guess

genius, he's only repaired scooters in his life until this engine, on the first attempt to start, it wouldn't start because he didn't fix the engine distribution, it's clear that the start was later because he dismantled the engine again and had time to paint the writing "ISUZU" in red :)))

Nice resto, but I cringed because with all that work you put in you didn't use a torque wrench even once. That's the only downside to the whole thing. Torque specs are there for a reason, and I can see the engine going Kaput in a few months. But other than that, great job!

This repair was quite thorough, but I did not see a tension wrench being used at all. The coupling between the engine flywheel and hydraulic pump was a Centaflex Series A and has been damaged by the oil that leaked on to it during operation, was swollen by the oil and definately should have been replaced. Anyway, that coupling is not the right solution, should have been a Centaflex H series coupling of the same size, torsionally much stiffer than the A series and is not affected by oil. I worked for Centa couplings for 20 years. Cheers.
