ACTION REQUIRED
This procedure only applies to engines with less than 250 hours.
Step 1: Verify oil level on the dipstick gage is at the full mark after engine has been shut off for 15 minutes. Adjust oil level if necessary and reconfirm oil level is at the full mark on gage before procedeing to Step 2.
Step 2: Use Cat Electronic Technician to run the Injector Fuel Delivery Test and repeat test for a total of four times. Test takes approximately 7 minutes for each run and is listed under the Diagnostic Test menu in Cat Electronic Technician.
Step 3: Shut engine off and recheck oil level after 15 minutes.
Result 1: If oil level did not rise return truck to service.
Result 2: If oil level has risen on gage due to fuel dilution, obtain an oil sample and replace high-pressure fuel pump, refer to RENR9707 Disassembly & Assembly guide for proper replacement of fuel injection pump. Maintain engine cleanliness and proper oil sampling practices at all times.
