Field Guides / Worksheets & decision tools
When a truck, tractor or standby engine is out of service, the price of the pump or injector is only one part of the decision. Freight, installation, substitute equipment and the value of missed work can exceed the component invoice. This calculator compares two options using numbers supplied by your organization; it does not use invented industry averages or collect your entries on a server.
Build a fair comparison
Include all relevant direct costs in the option’s repair field: evaluation, approved parts, installation, coding, freight and other required work. Set the same realistic downtime cost per day for both alternatives. A replacement may arrive faster but require an exchange core; a supported rebuild may preserve the original calibration but take longer. Verify part compatibility before comparing price.
Do not confuse revenue with lost profit. The appropriate downtime estimate is the actual economic impact of having the vehicle or machine unavailable, including any substitute or contractual consequences that truly apply. Avoid double-counting substitute expenses in both direct repair costs and daily downtime.
Compare two scenarios
Interpret the result
The lower total is not automatically the correct technical decision. Warranty terms, supported calibration, repair eligibility, expected reliability, safety and OEM procedure may outweigh a small projected cost difference. Revisit the comparison if the inspection discovers contamination or unserviceable components.

Use the authorized service inquiry to ask about testing or repair eligibility. A worksheet does not submit an inquiry or approve shipment.
