Overview – 28 “SUCTION FAN 3655260-20
The Cummins 28 “SUCTION FAN 3655260-20 is a direct replacement used in Cummins engine cooling as the 28-inch suction fan, with no modification required at installation.
Parts Characteristics
A 28-inch suction fan that draws cooling air through the radiator and heat exchangers, setting the airflow the cooling system depends on. Its blade pitch and balance decide whether the engine stays in temperature or cooks – so a true, balanced fan is the first line of cooling defence.
Applicable Models & Applications
Used on Cummins cooling layouts specifying this 28-inch fan. Match the blade count, pitch and hub against your old fan – suction fans differ in how they move air and clear the shroud.
Maintenance & Replacement
Inspect the fan for cracked or chipped blades and a distorted hub at every cooling service. A fan blade that lets go becomes a projectile in the bay and takes the radiator with it.
Confirm the fan is balanced after fitting. An out-of-balance fan vibrates the water pump bearing and the radiator mounts, and the vibration it starts outlasts the fan.
Check the shroud clearance. A fan that rubs the shroud loses airflow and destroys itself; the gap is part of the cooling design, not a detail.
Keep the correct 28-inch suction fans for your cooling system on the shelf. The engine cannot run without one, and the fan ships in a box.
