My friends mini digger was running rough and noisier than usual so I helped him diagnose the problem and get the machine working again.

When I grew up in my home town,street machines in Windsor Ontario Canada,were some if the fastest cars in Canada! One day a fella pulled in the drive of a friend's house,his 1970 Chevrolet was running very rough, so he parked it and shut it off,he tried to start it again,but it misfired,that's when his suspicions came true ,he had broke either the Crankshaft or camshaft street racing! Another thing that I know of,is one day my mother came to where I worked after driving 240 miles,she said something was wrong with our 1972 Buick. I cranked it over and I could hear a noise coming from near the transmission. So,I pulled thr engine out at work,then inspected the flywheel,it had cracked around the bolts,in a triangular pattern,with a very unique twist to it,each break,acted like an interlocking puzzle,some of the metal had formed a tapered edge going in an angle on all 3 sides preventing the flywheel from becoming part if the bellhousing or falling away from the crankshaft, so it stayed in place till she got to my work! God had his hand in this,although the car might have kept running,if she had shut it off if the flywheel has completely separated,I know it wouldn't have started ,as the ring gear is on the flywheel,which in an automatic,is just a thin steel disc,with gears!

Yes there are quality issues, but the Chinese manufacturers are learning and improving - and with a three year warranty I am very comfortable. I'll turn the machine over when the warranty expires and pick up a new one. And the purchase price is vastly lower than any of the big name brands. For *me* and my needs, it's compelling.

I bought my son a 72 Dodge Charger that he put a lot miles on to college and work everyday for a couple of years. Then he was driving to work in Orlando Florida 30 miles one way. One night he was late coming home so I asked him what happened. He said his car was using about a quart of oil a day and was now making a noise and vibration. I went to check it out and when he cranked it up, I knew it needed internal fixing. The machine shop showed me the broken crank. I couldn't believe he had driven it home 30 miles on the interstate highway (65 mph speed limit) and no one rear ended him since he was going so slow. I fixed the engine and my second son drove it afterwards for a couple of years. Tough 8 cylinder.

With the substantial cross section of that crankshaft I think you are spot on from my armchair there doesn't seem evidence of fatigue and given that it is just turning the hydraulic pump (almost constant load) there doesn't seem the mechanism for sudden shock. It was a failure waiting to happen. The replacement power unit dropped in just like a bought one. Great job.

@maxtorque2277 2 жыл бұрын
There is a HUGE cyclic load between the crankpin and the flywheel every time the cylinder fires, even at net zero crank torque! On a single cylinder diesel, the cylinder pressure is very high and the rate of pressure rise high (which is why diesels (and modern DI petrols) sound so "knocky" in fact) resulting in huge torsionjal vibrations. Look at the size and inertia of the flywheel, it's massive to damp those individual firing pulses out to try to get a smooth output speed and torque. On this engine, the flywheel is on the other side of the crankpin, so working loads also go through the pin to flywheel joint as well.
@bluegrallis
@bluegrallis 2 жыл бұрын
The "sudden shock" is every time the engine comes up on compression, then combusts. If that is a cast iron crank, I would say there is the problem. A forged steel crank would do much better service, as long as it had proper radii in the corners.

I have a similar machine with the Koop engine. And it's great. I get over a full day's work out of a 10 litre jerry can of diesel, so it's pretty economical for the amount of work it can do in that time.

How many people do you know that get to trouble shoot a motor issue for Sean Connery! Lucky guy. Those little ridges in the fracture surface are fatigue striations. Referencing the view at 5:48, it looks like the fracture started at the bottom and as the fracture moved up it beat the lower part smooth. Then when it got to the top it was catastrophic.

I cheered when I saw the new engine. Sometimes, you just have to jack up the radiator cap and drop a new machine under it! Good call. I know in my heart you could have fixed the old one. But, let's just say I have paid more a new VCR, and that was money well spent on future labor that will not be needed. Time is money. You ROCK!

There's something about hearing "There's your problem" when they're looking at a crank that's snapped in half that removes all confidence in the mechanic for about 3 seconds until you realize they were joking. Hopefully. 🙊🔧

Years ago, a neighbor had an M Farmall develop a "noise". He had just started corn picking for the year and finished, using that tractor to haul loads up from the field. That winter he and his son tore the engine down and found the crankshaft broke in two, similar to this one.

5:48 -- You can see the beach marks, the striations which represent the advance of the fatigue crack over time. The top was the last part to go, because it's shiny and crystalline, where the metal crystals have been cleaved apart.
