Dealer Cost Justification for Vibration Diagnostic System

Truck Vibration Technology 2

Premise

Using accurate, objective data to diagnose truck vibration problems saves significant time and money. This will pay for the cost of the diagnostic system very quickly, likely in one incident.

Using the Tool Two Components of Savings

• Hard-to-solve trucks present the biggest opportunity for cost savings with the tool. The wasted cost in a single truck of this type can easily exceed twice the cost of a diagnostic system. An effective diagnostic system saves this cost.

• A vibration diagnostic system saves time in the day to day process of solving vibration problems by eliminating wasteful diagnostic steps. This is accomplished by keeping you focused on the root cause of the issue as directed by the diagnostic system.

Part 1: Ineffective Parts Changing• Eaton studied the cost of “bad actor” vibration problems• 237 “stumper” vehicles were studied• The average cost of attempted repair was $9326 per

vehicle without the diagnostic tool• Ineffective parts changes drove this wasted cost. Typical

unrecoverable costs in ineffective diagnosis were:– Drive shafts $550– Master clutch $2600– Tires $4700– Transmission $8400

• When used, the Eaton diagnostic tool pinpointed the problem within two hours (setup and drive)

• Targeted diagnosis was then effectively completed and a fix was directly implemented

Conclusion 1

• Parts changing as a diagnostic procedure on problem trucks can be very expensive and wasteful.

• 30 minutes invested at the start of diagnosis to generate effective data can save thousands of dollars.

• $5200 invested in a diagnostic tool can pay for itself very quickly, likely in one incident.

Part 2: Every Day Savings

• A standard vibration diagnostic procedure is four hours without the tool

• Typical follow-up diagnosis without the tool takes eight hours

• The tool takes 30 minutes to install and 1 hour to use on a test drive

• After using the tool, time can be spent effectively on targeted final diagnosis and fixing the problem

• Using the tool saves wasted time on diagnoses that aren’t directed at the real problem

Existing Diagnostic Process (without data)

• Receive truck• Take for ride – 1 hour• Check ride height – 15 minutes• Check driveline angles – 15 minutes• Check yoke run-out - 30 minutes• Balance driveline – 2 hours• Check tire run-out – 30 minutes• Balance tires – 2 hours• Diagnose engine –30 minutes• Total – 6 hours• Additional time is incurred as issues are found,

corrected and verification road test performed.

Proposed Process

• Receive Truck• Instrument – 30 minutes• Take for ride – 1 hour• Do appropriate diagnosis – as dictated• When the DVA was used on the trucks

listed in the previous slide the average time to pinpoint the issue was 2.0 hours.

Key Concept

It is worthwhile to invest 30 minutes to setup for truck measurement to pinpoint the problem area so that you can save hours in going through diagnoses that are not relevant to the problem.

Overall Conclusion

A $5200 investment in a vibration diagnostic tool can pay for itself in one hard-to-solve incident or in just a few incidents of average complexity.
