These components belong to the gate-drive arrangement and should be selected against the exact operator drawing. They are separate from the output sprocket, motor and limit mechanism. When diagnosing chain tracking, noise or wear, inspect the mounting and surrounding drive components as well as the idlers; a new pair cannot correct a bent support or an incorrectly routed chain.\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\u003eHDSL24UL\u003c\/td\u003e\n\u003ctd\u003eVerify the exact idler kit in the model-specific service drawing.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eINSL24UL \/ IHSL24UL\u003c\/td\u003e\n\u003ctd\u003eDifferent industrial parts references; no automatic fit established.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHDSW24UL swing operator\u003c\/td\u003e\n\u003ctd\u003eA shared HD label does not establish this slide-drive application.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGarage-door rail idlers\u003c\/td\u003e\n\u003ctd\u003eDifferent service components and mounting arrangements.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChain or output-sprocket damage\u003c\/td\u003e\n\u003ctd\u003eInspect separately; neither is promised in this idler kit.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eInspect the Chain Path and Idler Mounting Together\u003c\/h2\u003e\u003cp\u003eWear at an idler may be a symptom of misalignment, damaged mounting hardware or incorrect chain adjustment.
