Our 8009N is a direct replacement/upgrade for Mack® applications of the HT650® / HT550® fan clutches.
The superior design of the 8009N makes for easier and more affordable long-term maintenance.
Converting your fan clutch upgrades it from a medium duty fan clutch to a heavy duty fan clutch. Our model is capable of handling a larger fan and will last longer than the competition.
When converting from an HT650® / HT550®, reverse your solenoid valve to air-to-disengage instead of air-to-engage.
