FAQ

Q: How do I know if this bracket fits my specific Cummins 6BT engine?
A: Please check the casting number on your old bracket or your engine’s parts manual. This part is a standard replacement for most 6BT and 4BT engines using a belt-driven fan, but variations exist between industrial and automotive versions. If unsure, contact us with your engine serial number for verification.

Q: What is the installation process for this bracket?
A: Installation is straightforward. First, disconnect the battery. Remove the fan, pulley, and belt. Unbolt the old bracket from the timing case cover. Bolt the new bracket into place using the original hardware. Reinstall the pulley, fan, and belt, ensuring correct belt tension. Torque all bolts to manufacturer specifications.

Q: Can a worn bracket cause other engine problems?
A: Yes. A cracked or worn bracket can cause the fan to wobble, leading to water pump seal failure, belt damage, and engine overheating. Replacing a damaged bracket promptly prevents more costly repairs and ensures the cooling system operates efficiently.
