The purchase of engine-rebuild parts should be the last resort for truck drivers and owners. It is possible to make common repairs on Cummins engines to prevent costly delays in shipping and delivery routes. A list of preventative measures should be applied to trucks every month to avoid engine-rebuild projects.
A typical garage at a trucking company has spark plugs, belts and other parts needed for engine repairs. An overlooked tool in diesel-engine maintenance is a stethoscope. This inexpensive tool allows mechanics to hear the inner workings of Cummins diesel engines, without expensive diagnostic methods.
The first test of a failing diesel engine should be an investigation of abrasive sounds under the hood. A few seconds with the stethoscope can help a mechanic diagnose problems with bearings, cylinders and valves. An examination of individual cylinders can eliminate pump-timing and systemic problems that lead to engine-rebuilding projects.
Another way to eliminate causes of diesel-engine problems is examining battery functions. The truck's battery can be checked out with a terminal voltage reader. The reader is attached to each battery port to assess the amount of current produced during operation. A costly engine rebuild can be avoided by switching out inexpensive parts like starter motors, batteries and cables.
A third way to diagnose diesel-engine problems is checking the dipstick. The stick can be placed against the heated manifold to create steam if the fuel has been infiltrated by water. Mechanics who note a combination of several problems may need engine-rebuild kits to keep trucks running.
The process of rebuilding a Cummins diesel engine can start with Internet Diesel. This company sells overhaul kits for Cummins, Caterpillar and Detroit Diesel engines to customers throughout North America.
