Coach Engine Alternatives

Many owners consider the power of the older coaches to be insufficient especially when driving in mountainous regions. Most of the converted Eagles have a Detroit Diesel 8V71 or a 6V92 engine, but with some engine compartment and cooling system modifications, the engine can be replaced. The replacement Cummins engines provide increased durability, increased torque and decreased emissions. The new engine includes the power steering pump, jake brake, alternator, starter housing and flex plate.

With our procedure for installing four-cycle inline 6 engines, we can retrofit the 855 Cummins (electronic or mechanical), the Big Cam 3 Cummins 400 horsepower, the Series 60 Detroit (electronic only) and the Caterpillar 3406 (electronic or mechanical). An engine replacement can be accomplished in about 30 days.Adding a turbo to a 8V71 engine is another alternative, which requires a complete engine overhaul, cooling system modifications, changing the pistons and changing the cam timing.

We can rebuild your Eagle engine compartment to accommodate a Cummins engine.

Engines purchased through our shop are built by the manufacturer, Williams Detroit or Cummins. They also come with a written warranty from the manufacturer. We install them at our shop and then a qualified mechanic from Williams Detroit or Cummins will come and do whatever is necessary to hook it up, start it and make any adjustments needed so it remains fully warrantied.
