Overview – PULLEY ADAPTER ASSEMBLY 3376087 Series
Built to Cummins specifications, the PULLEY ADAPTER ASSEMBLY 3376087 serves Cummins drive positions as the pulley adapter assembly mating the pulley to the shaft; the cross-referenced series below covers the most common substitutions.
Parts Characteristics
A pulley adapter assembly that locates and secures the pulley to its shaft, so the belt drives true and the accessory turns in line. It carries the alignment that the belt cannot hold alone, so a true, seated adapter keeps the drive from walking off.
Applicable Models & Applications
Used at Cummins drive positions specifying this pulley adapter assembly (series). Match the bore, the keyway and the bolt circle against your old adapter – pulley adapters differ in how they locate and clamp.
Maintenance & Replacement
Inspect for a loose fit and elongated holes at every accessory service. An adapter that has begun to shift lets the pulley wobble, and the wobble is what throws the belt.
Confirm torque and alignment on fit so the pulley runs concentric. An adapter canted on its shaft vibrates the belt and the bearing behind it.
Replace rather than shim a damaged adapter. An adapter shimmed past its limit flexes under load and the pulley drifts.
Keep the correct pulley adapter assembly for your drive on the bench. It is cheaper than a thrown belt, and it is exactly the part missing when a pulley needs remounting today.
