The supplier describes its CSL24V application, so earlier-model fit must be checked against the installed operator’s drawing. These pulleys belong to the belt connection between the motor and reducer. They are separate from the output-chain sprocket and chain idler, and replacing them does not provide a complete motor, gearbox or timing-belt assembly.\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\u003eCSL24UL\u003c\/td\u003e\n\u003ctd\u003eManufacturer service drawing identifies the pulley set.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEarlier CSL24V \/ CSL24VDC\u003c\/td\u003e\n\u003ctd\u003eVerify the exact drawing and installed drive before ordering.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eK16-GT2-7 timing belt\u003c\/td\u003e\n\u003ctd\u003eA separate component in the documented drive; confirm whether it also requires replacement.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eK75-50090 chain idler\u003c\/td\u003e\n\u003ctd\u003eDifferent function and position; not the motor\/reducer pulley set.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther operator families\u003c\/td\u003e\n\u003ctd\u003eNo universal fit based on motor horsepower or belt appearance.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eCheck Pulley Alignment and Belt Condition Together\u003c\/h2\u003e\u003cp\u003eThe pulleys and belt need to operate as a matched mechanical system. Inspect the belt teeth, pulley engagement, shaft fit and retaining hardware when diagnosing slipping, unusual noise or visible wear. A damaged belt or loose shaft connection can remain a problem even after both pulleys are renewed.\u003c\/p\u003e\u003cp\u003eDo not substitute a pulley with a different profile or diameter simply because it fits the shaft. The documented components establish the intended drive relationship. Have the technician check alignment and belt adjustment using the operator instructions, and investigate any binding in the gate or reducer before normal service resumes. A pulley replacement is not a way to increase gate speed or overcome an overloaded drive.\u003c\/p\u003e\u003ch2\u003eSpecifications and Product Identification\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003eK17-36530\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent description\u003c\/td\u003e\n\u003ctd\u003eGear-reducer pulley and motor pulley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVerified diagram\u003c\/td\u003e\n\u003ctd\u003eCSL24UL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupplier application label\u003c\/td\u003e\n\u003ctd\u003eCSL24V; verify the applicable revision\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeparate belt reference\u003c\/td\u003e\n\u003ctd\u003eK16-GT2-7 in the documented CSL24UL arrangement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeparate output sprocket\u003c\/td\u003e\n\u003ctd\u003eK15-41B17LKGH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eBefore Ordering\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMatch K17-36530 to the exact operator service diagram.\u003c\/li\u003e\n\u003cli\u003eIdentify both pulley locations and the installed belt reference.\u003c\/li\u003e\n\u003cli\u003eInspect shafts, retention hardware, alignment and belt condition.\u003c\/li\u003e\n\u003cli\u003eDetermine whether the repair also requires a belt, motor or reducer component.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThe manufacturer names a gear-reducer pulley and motor pulley under this reference.
