The supplied catalog identifies K75-50090 as the manufacturer part number for this Q013 item. The CSL24U repair-parts diagram identifies Q013 as an idler pulley with hardware. Match the exact operator configuration and mounting location before ordering, and have the surrounding chain path and drive components inspected so a new idler does not leave an underlying alignment or wear problem unresolved.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eQ013\u003c\/td\u003e\n\u003ctd\u003eSupplier item reference for the idler pulley with hardware.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eK75-50090\u003c\/td\u003e\n\u003ctd\u003eManufacturer cross-reference recorded in the supplier catalog.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSL24U\u003c\/td\u003e\n\u003ctd\u003eThe manufacturer parts diagram identifies Q013; confirm the exact operator configuration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther slide-gate models\u003c\/td\u003e\n\u003ctd\u003eRequire their own parts-diagram confirmation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrive sprocket \/ belt pulley\u003c\/td\u003e\n\u003ctd\u003eA different component function; do not select by the word pulley alone.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eIdentify the Idler’s Location Before Ordering\u003c\/h2\u003e\u003cp\u003eA gate drive can contain several rotating components with different functions.
