Do not operate or work on this engine unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings could result in injury or death. Contact any Caterpillar dealer for replacement manuals. Proper care is your responsibility.
Keep hands clear of fan and belts while engine is running.
Making contact with a running engine can cause burns from hot parts and can cause injury from rotating parts.When working on an engine that is running, avoid contact with hot parts and rotating parts.
Specifications
Table 1
Air inlet Vacuum Pressure Specifications
Test location is anywhere on the air inlet pipe between the air filter and the turbocharger
Maximum Vacuum Pressure
For a used engine air cleaner 5 kPa (20 inch of H2O)
For a new engine air cleaner 3 kPa (12 inch of H2O)
Table 2
Exhaust Outlet Pressure Specifications
Test location is anywhere on the exhaust pipe between the exhaust manifold and the muffler
Maximum pressure is 10 kPa (40 inch of H2O) Introduction
This inspection checks the inlet air system for restrictions and checks the exhaust system for excessive back pressure.Required Tools

(1) This sensor must be purchased separately and is not included in the 198-4240 Digital Pressure Indicator Gp
(2) This sensor can only be used on large diameter pressure taps like 6V-3965 Fitting.Test Preparation
Remove all covers that obscure the air inlet and exhaust systems.Test Procedures
Air Inlet Restriction
There will be a reduction in the performance of the engine if there is a restriction in the air inlet system or the exhaust system.
Inspect the engine air cleaner inlet and ducting in order to ensure that the passageway is not blocked or collapsed.
Inspect the engine air cleaner element. Replace a dirty engine air cleaner element with a clean engine air cleaner element.
Check for dirt tracks on the clean side of the engine air cleaner element. If dirt tracks are observed, contaminants are flowing past the engine air cleaner element and/or the seal for the engine air cleaner element.
Use the differential pressure gauge of the 198-4240 Digital Pressure Indicator Gp.
