...I think its a stretch to believe there would still be oil on the dipstick after a weekend of hanging in no oil.
A drop hanging on the end sure, but definitely not inside the marks. Tough situation there.
...I think its a stretch to believe there would still be oil on the dipstick after a weekend of hanging in no oil.
Operator said he was about a half a mile (1km) before any light came on, also showed low oil pressure on the screen, he shut down, when the mobile mech showed up and they restarted the engine to here what was going on it sounded a lot like a couple of injectors was going, they shut down then pulled the stick, nothing on the marks, they then added oil restarted and major noise shut back down, what ever was laying in the pan was now pushed through to the oil filter and plugged it solid.... panic set in....mother Cat was called.I would guess it played out something like this. Machine did not have oil in it Monday morning, operator may/may not have pulled the dipstick before starting the engine. After starting and lights flashing/warning buzzer not shutting off due to lack of oil, operator shuts off engine and proceeds to investigate. After discovering the engine had no oil, and proceeding to $hit in his pants, he fills engine with oil. Crosses fingers, starts engine, lights go out, and he breathes a sigh of relief. At this point, the damage was done. Backs out of shop, loads up lunch box, heads out. We know what happens next. I don't believe that the engine would run more than a minute or two with no oil, even if it had been running synthetic and Lucas. JMO.
Mate, it's surprising just how long an engine will run without oil. Many moons ago I was operating an excavator when the sump got smashed. It couldn't be repaired were it was so I had to climb it out from were it was and park it in a better location. It took about 15 minutes at idle. After the repair that machine went on to many thousands of trouble free hours on 30 grade mineral oil..

Tractors aren't even as good as they once were, and the really good ones were done away with after the Challenger name was sold to AGCO.As far as I'm concerned, the only thing Cat makes that is any good any more is
a tractor. The last good loader was the F. I think that in order to stay competitive, that quality has gone out the window
Interesting comment. Maybe the idle situation helped? All I have for a testimonial is some 20 odd years ago, my dad was driving our 1978 IH with a DT466 home, and the oil plug fell out. Judging from where the slick started to where he coasted to a stop on the shoulder, the engine ran for maybe a minute before locking up tight. I'm not disputing your story, actually kind of wish that truck engine would have fared as well as your excavator. That was a $10,000 bill back in 1993 that we really didn't need at the time.Mate, it's surprising just how long an engine will run without oil.

Sorry, when I say tractor around here it means a bull dozer. But I do agree about AGCO.Tractors aren't even as good as they once were, and the really good ones were done away with after the Challenger name was sold to AGCO.
Didn't you say the filter was full of metal? Wouldn't it take some oil to get the metal there?I would say the block is a reman, what I think happened was the pm was done on the grader late Friday afternoon by our mobile mech he was called away on a emergency call out before finishing the pm but failed to tag out the machine before leaving, that same week the operater for that machine was on vacation he came in the following Monday pulled the dipstick in the machine when finishing up his pre trip and seen the old oil leftover that was drained on the safe operating marks on the stick and thought every thing was fine he didn't wipe and recheck, he did not see any tag out card on the machine and thought every thing was good to go, low and behold we lost a engine, both the operator and the mobile mech aren't saying much, this is why following pre trip procedures to the letter for your machine is so important. any opinions on this issued are welcomed thanks

They added oil and started it up and shut it back down when the noises got real bad. Post 23.
I see you point but my argument is on start up if there is not sufficient oil pressure the alarms go off and engine shuts down to protect the engine from damage before moving the machine,(engine monitoring system) this is the safe guard Cat should have in place, manufactures have many safe guards in place in their machines to protect humans (seatbelts, back up beepers, signal lights, brake lights, buzzers and alarms, ergonomics, back up electric brake, just to name a few) but nothing in place to protect the heart of the machine the engine. thanks for opinion.The manufactures don't put shutdowns on engines to protect humans. Sentinels have the possibility of shutting down an engine with a human in a precarious place. The decision to shut down an engine for whatever reason is always in the operator's hands. There are indicators and alarms in machines to alert operators of the current status. One would assume the human running the machine has the proper training and the physical ability to operate the machine safely.
Turn your argument around the other way and assume the operator is running down the road at forty miles an hour and the engine suddenly shuts down from a loss of oil pressure. Now you have twenty to thirty tons of dead steel careening through what ever traffic or pedestrians that have the misfortune to be in the way. Now the manufacturer is responsible for that unfortunate accident.
I agree, in you last post you mentioned machine shutting down running down the road, Cat has a back up electric brake in the m series for that very scenario, you have 10 seconds to pullover and stop before that safe guard electric brake burns up, $5000 to replace after using it, if this back up failed and did not come on and you ran over somebody Cat would be liable, especially if there was no code prior indicating it was not functioning properly. thanksYou are free to add a Murphy system at your own expense. I've looked a plenty of machines that have them. Don't expect to ever see a manufacturer do it though.
Also keep in mind that the functions you have listed were mandated by government.
This new stuff doesn't even have a oil pressure gauge. My pickup is the worst- there's a gauge in the cluster but it's just showing an algorithm programmed into the ECM.
