60 Series Detroit Diesel

Recommended Posts

Does anyone have information on 2005, 515 HP 60 Series Detroit Diesel? How do they compare to a 500 HP Cummins? More or less Maintenance? I know there differences with power to weight ratio but generally how is the economy (mpg)?

More intercity busses in that time frame ran the Detroit 60 series than any other. Very dependable and repair shops easier to find than other engines for coach use. Cant compare fuel mileage though.

What is the displacement on the 60 series DD and the weight of the coach?

Herman, if it was maintained properly you should have no issues. We have them at work with over 1 million miles. IMHO that was the best engine Detroit diesel made pre-emissions.

As for fuel mileage, with 515HP 1650 ft lbs torgue @ 1200 rpm, the determining factors as to how good that is, is weight, how you drive, how you drive, and how you drive. The weight factor for a MH, (unless of course your wife is a rock collector like Lucy), is almost negligible for that engine.

Sun, that is one that I would definitely take pictures of if I had to replace any one of the four belt.:wacko:

That is barley broken in. My ISM Cummins came to me with 125,000 miles on it and I wasn't concerned.

As a comparison, my DD 13 is 12.8L, 781CC, 500 HP, 1650 ft/lbs torque and weighs about 2,580 with it's 42 quarts of oil.

Wow that is a lot of oil. I am glad my ISM only takes 40 quarts of oil. :P By the way I am running Shell Rotella T-6.
