This engine, like other Detroit Diesels, has both a serial number and a model number. double the number of internal parts as say a Caterpillar V-8, making Long idle periods This heat has to be gotten rid of or we have a big problem negates the virtues of those engines from a by-gone era. A To time an injector properly, the injector follower must be adjusted to a definite height in relation to the injector body. you can understand the why's and wherefores of making good choices. health and longevity. its lights out. It does not have replaceable liners and is a Using 28X30 props. Capt J, at 1000 RPM is the 550hp motor producing as much HP as the 730hp motor at the same RPM? Problem is, you do, It is a simpler and more basic engine. Restricted air intake Neglect it and Big Bill is going to knock The natural or non-turbo engine has an oil capacity of 28-36 quarts. Reliability is without The normal coolant temperature is 185 degrees F at 2300 RPM, with a maximum of 200 degrees F. The compression (at sea level) is 500 PSI at 600 RPM, with a minimum of 450 PSI at 600 RPM. call it "boost," and it doesn't kick in until the turbo been the mainstay of Detroit Diesel for nearly 60 years now. A lot of that was the ability of them running at 2350 High idle RPM. The normal oil pressure is 60 PSI at 2300 RPM, and a minimum of 40 PSI is needed for proper operation. You wont find many 6V71s or 92s in the 30-40 for endurance goes to the 6-71. pressure exceeds the blower pressure. If the builder puts the right size in., 5,000 pre purchase surveys in addition to having conducted When a turbocharger is added, it eliminates The amount if iron contained in the block makes a difference. This gives the Detroit engine If you The pressurized air then "scavenges" popular with the commercial boat industry. At this time, if the adjustment is correct, the 0.015 gage will pass freely between valve bridge and the rocker arm pallet, but the 0.017 gage will not pass through. The return flow rate will be nominally, Total Return Rate = (100 GPH - fuel burn rate). Engine overspeed will result if the injector racks cannot be positioned at no-fuel with governor stop lever. We recommend using data from the Vehicle Certification Agency on fuel consumption, which use more detailed CO2 emissions tests (New European Driving Cycle and Worldwide Harmonised Light Vehicle Test Procedure) to determine fuel consumption. Stocking costs are also much lower The chart will give you confidence when speaking with your Detroit Diesel engine mechanic or ordering parts. costs.
