Component Testing

Engine parts and industrial components can be expensive and complex, making the troubleshooting process difficult. D&W maintains a wide variety of testing equipment and a library of manufacturer testing specifications so you don’t have to. We can help you determine if a suspect component is performing properly or needs to be repaired or replaced. The testing services offered by D&W include:

Some tests are performed at no charge, while some are more involved, take more time and carry a nominal charge. Even so, a small fee spent to determine whether or not a unit needs to be replaced can save you a lot of time and money in the long run.

If your unit fails the test(s) you request, D&W offers repairs, remanufactured exchange and new replacement programs for many product lines. If the unit in question passes the tests but your system continues to malfunction, our product experts can work with you to identify the cause of the underlying problem.

D&W also has a variety of testing equipment available for customer purchase. Your local D&W location can provide you with more information on specific testing equipment options.

It’s a lot cheaper to test than it is to guess. Call D&W about component testing options.
