Product Description
CUMMINS Belt-drive component 0120-1369
1. Product Overview
CUMMINS Belt-drive component 0120-1369 is listed under source title “SHAFT IDLER GEAR”. It is classified for Batch 3 as belt-drive component within the accessory drive system. The source record does not establish an exact engine model. Confirm the complete engine model, serial number, arrangement, and installed reference before ordering.
2. Function and Operating Principle
A belt-drive component transfers rotation from the engine to an accessory or guides and tensions the belt path. Belt profile, effective length, pulley diameter, groove form, alignment, and tensioning arrangement must match.
Friction between the belt and pulley transmits torque while idlers and tensioners control wrap, alignment, and tension. Wear, contamination, misalignment, or bearing condition can reduce drive reliability.

4. Typical Signs That Inspection May Be Required
