Cummins engine

This coach is powered with the famous Cummin’s 5.9B inline 6, with turbo.  It is rated at 230 hp, powered thru the Allison 4 speed automatic. Foretravel spec’d this engine at 230 horsepower. Note most coaches by other manufacturers spec’d less horsepower. For instance 190 was a cheaper choice. In addition the first owner installed a Pac Brake, and dash switch as soon as he took delivery.  Pac Brake is an engine brake in the exhaust system, that works on a “no throttle” sensor to help slow the coach, or to control down hill travel.

This coach has had upgrades to the engine cooling.  The second owner installed an aluminum radiator to the front behind the grill to help with summer cooling needs.  There is a manual shut off, for winter driving.  The second owner also had the main radiator reworked, a new pump and dynoed at Cummins in OK.  We have enjoyed 7,000 miles in the last 2 years in Texas without problems.  We have replaced a number of small items on the engine.  Of note have been the D2 regulator on the air system, the air dryer, the fuel filter mounting base, and a couple of new senders.  Access is under the lifting bed deck and easy for spot checking.  No parts have been replace in over a year, and our 7 weeks of trips this year we have had zero issues.

We get on average 8 mpg, towing at speeds between 60 and 65, loaded as we like, towing a light weight Saturn station wagon.  All fuel use, mileage and costs have been recorded and the list is in the coach.

We enjoy traveling just below the posted speed limits, with the cruise on, and enjoying the views from the wrap around windshields.

The fuel filter is the white part, and mounted on a new engine mounted bracket.

The silver cylinder is mounted on the blue bracket, is the Pac Brake exhaust brake.  It is controlled by the dash switch, and closes when on, and you lift off the throttle.
