Attach.(1-Rework Procedure)Rework Procedure
This Program only applies after a customer lodges a complaint concerning engine performance (either a lack of horsepower or poor fuel economy).
1. Conduct a customer interview to determine the exact basis of the complaint. Begin by asking "Why are you saying that you have a performance complaint?"A. If the customer's answers indicate a horsepower loss over time, or are specific and similar to the examples listed below, go to Step 2: A 10% fuel mileage decrease (0.5 to 0.7 mpg) is normal when comparing winter to summer operation, assuming the application of the tractor did not change (same loads, speed, idle time, etc. ...).
This procedure is not intended to correct a 1 mpg fuel economy complaint. Such complaints are usually not engine related.
B. If the customer's answers do not indicate a horsepower loss over time, are not specific nor similar to the examples listed below, STOP this Program does not apply: 2. Determine if new 1007600 Nozzle Assemblies (or 0R4337 Nozzle Assemblies) were installed in this engine during a previous repair? 3. Determine if the FARC (Fuel / Air Ratio Control) setting changed during a previous repair? 4. Perform the basic checks listed below. While performing these basic checks, the engine should NOT be operating. Some of the basic checks may have to rely on the customer's perception. The intent of the basic checks is to eliminate obvious functional problems before performing the dynamometer test. If the basic checks are all OK, go to Step 5. If the basic checks are NOT OK, fix the problem item(s). If the customer is satisfied after the basic check problem item(s) are fixed, STOP. If the customer is still unsatisfied after the basic check problem(s) are fixed, go to Step 5.
5. Perform a PAR dynamometer test. The fuel rates charts below are corrected to EPA certified fuel rates for the performance specifications and serial number ranges involved in this rework. If the engine performance is within the PAR specification band, the customer is responsible for the expense of the PAR test. If the engine performance is outside of the PAR specification band, install six 0R4337 Nozzle Assemblies
