Overview – BELT-FAN 31PK-1805 J0130-8257
The Cummins BELT-FAN 31PK-1805 J0130-8257 is a direct replacement used in Cummins engine accessory-drive positions as the multi-rib fan drive belt turning the fan and the driven accessories, with no modification required at installation.
Parts Characteristics
A belt-fan 31pk-1805 that turns the fan and the driven accessories from the crankshaft in the engine accessory drive, so the cooling and charging stays driven as specified. It carries the service life the engine accessory drive depends on, so a true, correctly specified unit keeps the glaze, crack and slip from the engine overheats and the battery goes flat.
Applicable Models & Applications
Used at Cummins Engine Parts positions specifying this BELT-FAN 31PK-1805. Match the profile, length and mount against your old unit – Engine Parts parts differ in how they seat and bolt.
Maintenance & Replacement
Inspect for wear and a loose fit at every service. A belt-fan 31pk-1805 that has begun to fail lets the cooling and charging drift, and the drift is what causes the glaze, crack and slip.
Confirm the belt-fan 31pk-1805 seats and the fixings hold on fit. A unit canted in its bolts lets the cooling and charging move, and the move is where it fails.
Replace rather than repair a failed one where the part allows. A belt-fan 31pk-1805 reused past its life returns the same fault, and the fault is what stops the machine.
Keep the correct belt-fan 31pk-1805 for your engine parts on the bench. It is cheaper than the downstream failure, and it is exactly the part missing when a service needs doing today.
