CtG Posted February 19, 2020 Share Posted February 19, 2020 Just thought folks might appreciate this. ~5000lb 18L diesel, hydrolocked and bent a rod, as well as the crank. The rods and crank are forged. The crank is 47" long, and the main journals are just over 4.75" diameter. High quality steel, forged well, heat treated and shot-peened. Talk about some force to distort those pieces cold. Well, ~200°F operating oil temp anyway. Quote Link to comment Share on other sites More sharing options...
Chris C Posted February 19, 2020 Share Posted February 19, 2020 That's the biggest darned go-cart engine I've ever seen! Quote Link to comment Share on other sites More sharing options...
Jasent Posted February 19, 2020 Share Posted February 19, 2020 Looks like the motor in our backhoe. Quote Link to comment Share on other sites More sharing options...
swedefiddle Posted February 19, 2020 Share Posted February 19, 2020 Good Morning, When something goes stop and inertia says I'm still moving, something WILL fail. Machinery can be repaired or replaced, not so easy on a person. I hope nobody got hurt!! Neil Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted February 19, 2020 Share Posted February 19, 2020 Will all that broken stuff get to follow ya home? Quote Link to comment Share on other sites More sharing options...
CtG Posted February 19, 2020 Author Share Posted February 19, 2020 No worries Neil, the operator is healthy and well- not happy, he is in the old compactor until we get this sorted, but he is well! Certainly. The engine is mated to a 3 speed planetary gearset, as well as 5 hydraulic pumps. While I couldn't nail down an accurate rotating inertia energy, I can tell you it is SUBSTANTIAL. Even at low idle, you are looking at 700RPM, and we are talking over a quarter ton of rotating components. Your backhoe (if the right color of yellow!!) Is a 4.4L 4 cylinder manufactured in England. A Perkapillar as it were haha Though.... if you mean an excavator/track-hoe, it would be an AWFULLY big unit to have an 18L in it!! 100 ton plus class! Chris, if you make a 600HP(1500RPM), 2400ft/lb(1300RPM) Go-Kart.... I WANT A RIDE!! Unless the EGR cooler fails, these babies can make that kind of power for 20,000+ hours of use. The C15 and C18 engine family is tried and true- soooo many truckers would love to have the 15L CAT back in trucks IF&C, unfortunately not. This unit is under warranty, and Big Momma CAT is going to want E-V-E-R-Y-T-H-I-N-G back for testing.... That, and I don't think my JABOD could handle that crank hahaha Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted February 19, 2020 Share Posted February 19, 2020 Too bad; that's the sort of failures folks would put on the shop walls as warnings to new people. (In IT we would hang up the "best" disk crashes with a sign saying: "Have you backed up your critical files lately?") I would not want to ride in a go cart powered by that because at some point---you gotta STOP! Quote Link to comment Share on other sites More sharing options...
CtG Posted February 19, 2020 Author Share Posted February 19, 2020 Eh, just build in a ripper- when you gotta stop, drop the shanks! Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted February 19, 2020 Share Posted February 19, 2020 It turns out that racetracks frown on that sort of thing---like bringing a cannon to a shooting range. Probably need some good design engineering not to flip it when you pop the clutch....I've seen the V8 motorcycles; but after seeing a Saturn 5 launch in person everything below a million hp is just paltry...

CtG Posted February 19, 2020 Author Share Posted February 19, 2020 Yeah, Saturn 5 would have been an incredible sight. Amazing the engineering, sticktuitiveness, and genius that went into that series of monsters. And what they overcame. To think, with the primitive systems they had at the time they still were able to detect and shut down pogo'ing before catastrophic failure. There is a C12 Rat Rod out there that would be pretty cool to duplicate. Or maybe Pissed Off Pete (8V71). Just get the appropriate flywheel housing and an RTLO22918 will mount right up. Looked it up, the crank is 495lbs. So between it and all the rotating assembly in the powertrain, it is probably closer to 1/2-3/4 ton of rotating mass, in neutral and parked.

Charles R. Stevens Posted February 19, 2020 Share Posted February 19, 2020 I want to know how the men who climbed aboard a Saturn V walked, the suits didn’t look like they had enough room for a pair of bowling balls... Quote Link to comment Share on other sites More sharing options...
