Engine: ISB Cummins 7
Capacity: 84 Passenger***
Condition:* Bus has leaking steering gear box
Below are some notes I conjured up which speak to the reliability and longevity of the engine and trans. Correct me if I'm wrong but the repair it needs and the mileage shouldn't be a deal breaker being that's it's all good under the hood. Am I right? Auction guy says he'll let it go if it's in the neighborhood of $4k.
"The MD3060 is a four speed with overdrive and* lock-up torque converter. Go with a trany that has the* lock-up torque converter. You will usual get better gas millage over all and engine braking on the down hills. MD3060 on 1998 and newer. I also read that the MD3060 has the internals to be re-programmed with 2 overdrives. Making it a six speed."
*What bus to get, that is the question, part tali (two) | the journey visvi
*"I have an ISB in a 34' Newmar. On my last trip I got 8.73 mpg over 2760 miles towing a 4x4 extended cab ranger with 3 motorcycles (dirt bikes) and traveling 60-65 mph. It does slow considerably on the long steep climbs, but even there I manage to pass a lot of the semi trucks. I don't how much difference the extra 4 or 5 feet will make but obviously it will make some difference. If you can handle being a little slower on hills then I think you could be very happy with the ISB"
