Frequently Asked Questions
What does the Caterpillar Air Filter 1106326 do?
The 1106326 air filter protects your Caterpillar engine from dust, dirt, debris, and other airborne contaminants that would cause accelerated wear on pistons, rings, and cylinder liners. A clean air filter is essential for maintaining proper air-to-fuel ratio, fuel efficiency, and engine longevity in tough jobsite environments.
How often should I change the 1106326 air filter?
Caterpillar recommends checking the air filter restriction indicator at every service interval and replacing the filter when the indicator shows red or the filter is visibly clogged. In very dusty conditions ??? such as demolition, quarry, or agricultural work ??? more frequent replacement may be necessary regardless of the indicator reading.
What happens if I continue operating my CAT equipment with a dirty air filter?
A severely restricted air filter starves the engine of combustion air, leading to incomplete fuel burn, increased black smoke emissions, a significant drop in power, higher fuel consumption, and in the worst case, accelerated cylinder wear from dust ingestion if the filter fails. Timely replacement protects one of your most expensive components.
Is the 1106326 air filter a high-quality aftermarket part?
Yes. The 1106326 air filter from Propel Parts is a premium aftermarket replacement that meets or exceeds OEM specifications for filtration efficiency and air flow capacity. It is manufactured with quality filter media and proper sealing surfaces to ensure no unfiltered air bypasses the element.
Which Caterpillar models is this air filter compatible with?
The 1106326 air filter fits specific Caterpillar equipment models and engine configurations. Check your Operation and Maintenance Manual for the correct filter part number, or reach out to Propel Parts for help verifying fitment using your model and serial number.
Should I also replace the safety (secondary) air filter element at the same time?
The secondary or safety element should NOT be changed at every service ??? it is designed to remain in place as a last-resort backup. Replace the safety element only if it is visibly damaged, if the outer filter fails, or after 3???5 primary filter changes. Cleaning or disturbing the safety element unnecessarily can allow fine dust into the intake.
