CATERPILLAR-3054-3056-REAR-CRANKSHAFT-SEAL-Viton

4W5360 is a rear crankshaft seal for Caterpillar's 3054 and 3056 engines, made from Viton rather than standard nitrile rubber. Viton holds up significantly better against heat and oil additive chemistry over time, which is why it's specified at the rear crank position on some builds where seal life under sustained running temperature matters more than the cost difference.
