I have driven every kind of truck with every kind of engines, Detroit, Cummings, gas ,diesel and when I started driving, I could not get enough. Yep those were the days
Yes it's a disaster youth has the ability to make you think your having fun, but trucks are dangerous, now I think about my days of driving as a Morron behind a wheel, if your are beside the wheel of a trucks, and it expires, it can hurt anyone beside the truck with pieces of debris
@@michaelclendenen4005.... Bath tubs and showers can be dangerous to... you might slip and break your neck, and it's "lights out" for you! Perhaps we should try and "outlaw" them as well. Trucks, hammers, Guns, knives, 2x4's, kitchen knives, baseball bats, Roller Skates, Skate Boards, Ultralight Aircraft, Parachutes, table saws, band saws, etc, etc, etc.... in & of themselves, are inanimate objects that pose No danger to anyone..... it's only either by purposeful intent, or by accident of the person in control of it, or by some other unforeseen situation that "may" cause said object, injury or even death to anyone.. who just happens to "be in the right place, at the wrong time". National Documented Statistic.... More car/semi accidents, are proven caused by the "4 wheeler" (of whatever type) in over 76.8% of the accidents... National Hwy Patrol Assoc. and Assoc. of National Insurance Agency Records are within .5% percentile of each other, last time I checked. With the ever increasing combination of Arrogance and Stupidity of many "4 wheeler" drivers around semis and other loaded trucks these days, that I've been seeing in the last 10 years or so.... that percentile is growing. Have a safe life.... and have & show respect for the trucks and the weight thereof, if not for (some of) this younger generation of truck drivers....
Yes, I have seen a lot of 6v71s in our construction equipment, I don't care... They are loud but nothing sounds like a Detroit! I did some clutchless shifting in an old Chevy Brigadier and the only way to run that thing was to put it to the mats and make it scream!
A 6-71 Detroit in a B or L model Mack rare as hens teeth. I once saw one repowered in a Flintstone as a circus truck hauled 3 elephants around with belly tank of water underneath.
I work for a company in santa maria california back in 1984 we had an air compressor and it said joy on it and it had twin 871 jimmy's called a set from a tank I had to start it at the job site and it just about scared the b jigger's out of me when all of a suden it went to full throttle I was about 3 feet from it I never heard something that loud and from then on I would start it and run like the devil was on my but just a memery
Ah.. dude.... you described a 4 stroke diesel engine. Old Detroits are 2 stroke. First, there are no fuel injectors on a 2 stroke Detroit, instead a blower forces a fuel/air mixture towards ports near the bottom of the cylinders. When the piston is at bottom, the ports are uncovered allowing the fuel/air mixture to be forced up into the cylinder, pushing the exhaust gasses out the valves at the top. As the piston moves to top it covers the ports while the exhaust valves close, allowing compression to be achieved. The combustion then pushes the piston down in its power stroke. The process then starts over with the exhaust valves opening and the cylinder ports being uncovered. Every revolution of the engine has a power stroke unlike the every other revolution in a 4 stroke engine. This is what gives old Detroits their unique sound and why they had higher power to weight ratios of similar sized engines back in the day. This also gives way to the legendary reliability of the two stroke Detroits, no injectors or ignition systems to fail.
Everything you said was correct except that it does not have injectors. It does have injectors. It has one for every cylinder. The center rocker arm pushes on the injector and squirts diesel in the combustion chamber. The only thing it does not have is air intake valves.
Alan Zimmer. Check out other RU-vid vids showing tuning and maintenance on Detroit’s they certainly do have injectors. Otherwise it is all as you described. Cheers
