Information:
Checking Backpressure with Manometer/Gauge
Remove the plug from the pressure tap coupling located on the manifold immediately after the engine and install a manometer or pressure gauge. Use a gauge with a minimum range of 0 to 20 kpa (0 to 80 inch of H2O).
After completely warming up the engine, run at no load, wide open throttle (W.O.T.) for 2 to 3 minutes. Record the pressure reading while the engine is running at no load, W.O.T. Repeat 2 to 3 times.
If the observed backpressure is less than 10.20 kPa (41 inch of H2O), the DPF can continue to be operated without further maintenance.
If the backpressure is greater than 10.20 kPa (41 inch of H2O) at the time of installation, contact your Caterpillar dealer. If the backpressure is greater than 10.20 kPa (41 inch of H2O) during a maintenance check, contact your Caterpillar dealer. Your Warranty Rights And Obligations
VERIFIED PRODUCT WARRANTY
Caterpillar Inc. warrants the diesel emission control system in the application for which it is sold or leased to be free from defects in design, materials, workmanship, or operation of the diesel emission control system which cause the diesel emission control system to fail to conform to the emission control performance level it was verified to, or to the requirements in the California Code of Regulations, Title 13, Sections 2700 to 2706, and 2710, for the periods of time listed below, provided there has been no abuse, neglect, or improper maintenance of your diesel emission control system, vehicle or equipment, as specified in the owners manuals. Where a warrantable condition exists, this warranty also covers the engine from damage caused by the diesel emission control system, subject to the same exclusions for abuse, neglect or improper maintenance of your vehicle or equipment. Please review your owners manual for other warranty information. Your diesel emission control system may include a core part (e.g., particulate filter, diesel oxidation catalyst, selective catalytic reduction converter) as well as hoses, connectors, a backpressure monitor (if applicable), and other emission-related assemblies. Where a warrantable condition exists, Caterpillar will repair or replace your diesel emission control system at no cost to you including diagnosis, parts, and labor.WARRANTY COVERAGE
For engines used in verified applications, the warranty period will be in years or hours or miles of operation, whichever occurs first, based on the following chart:
Table 1
Engine Type Engine Size Minimum Warranty Period
On-Road Light heavy-duty, 70 to 170 hp, Gross Vehicle Weight Rating (GVWR) less than 19,500 lbs. 5 years or 60,000 miles
Medium heavy-duty, 170 to 250 hp, GVWR from 19,500 lbs. to 33,000 lbs. 5 years or 100,000 miles
Heavy heavy-duty, exceeds 250 hp, GVWR exceeds 33,000 lbs. 5 years or 150,000 miles
Heavy heavy-duty, exceeds 250 hp, GVWR exceeds 33,000 lbs., and trucks are:
1. Typically driven over 100,000 miles per year, and
2. Have less than 300,000 miles on the odometer at the time of installation. 2 years, unlimited miles
Off-Road (includes portable engines) and Stationary Under 25 hp, and for constant speed engines rated under 50 hp with rated speeds
