{"product_id":"liftmaster-k80-5001","title":"LiftMaster K80-5001 Shaft Key — 3\/16 x 3\/16 x 1-3\/4 Inches","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K80-5001 is the shaft-key service item described in the supplied record and service listing with a 3\/16-inch by 3\/16-inch by 1-3\/4-inch designation. Manufacturer catalogs shorten the description to keyway. This identifies a mechanical drive key, not a cabinet or access key. Match the exact shaft, hub and service drawing before ordering. Select the replacement by the complete part number and the installed equipment configuration. A similar photograph or a shared LiftMaster brand name does not establish interchangeability. Confirm the applicable service drawing before ordering so the repair addresses the correct component and its related mounting, connection and operating requirements.\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\u003eSpecified keyed drive\u003c\/td\u003e\n\u003ctd\u003eMatch K80-5001 in the actual service drawing.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKey dimensions\u003c\/td\u003e\n\u003ctd\u003eConfirm all three listed dimensions and end form.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShaft and hub condition\u003c\/td\u003e\n\u003ctd\u003eInspect keyway wear before selecting a key-only repair.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccess or cabinet locks\u003c\/td\u003e\n\u003ctd\u003eThis mechanical key is not a lock credential.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eIdentify the Assembly and Plan the Repair\u003c\/h2\u003e\u003cp\u003eA keyed drive depends on the fit of the shaft, key and hub together. Inspect both mating keyways for wear or damage and identify the cause of a loose or displaced key. Replacing the key alone cannot correct an enlarged keyway, cracked hub or another attachment fault that continues to allow movement.\u003c\/p\u003e\u003cp\u003eConfirm the approved key form and any required separate retaining hardware before service. The catalog term keyway should not be interpreted as a complete replacement shaft or machined hub. Do not grind or shorten a replacement as an improvised repair without an approved specification. Restore the documented drive alignment and retention and complete the affected operating and protection checks after installation.\u003c\/p\u003e\u003cp\u003eCompare the replacement with the installed service arrangement before dismantling the equipment. Photograph the part’s location and record the complete model and visible service numbers. Inspect the surrounding attachment points and mating components for wear, impact damage or misalignment. Replacing one worn item will not correct a damaged support or another component that continues to impose abnormal loads on the repaired assembly.\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\u003eOrdering reference\u003c\/td\u003e\n\u003ctd\u003eK80-5001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent\u003c\/td\u003e\n\u003ctd\u003eMechanical shaft key\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize designation\u003c\/td\u003e\n\u003ctd\u003e3\/16 x 3\/16 x 1-3\/4 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCatalog wording\u003c\/td\u003e\n\u003ctd\u003eKeyway\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSelection check\u003c\/td\u003e\n\u003ctd\u003eActual shaft\/hub keyways and approved retention arrangement\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\u003eRecord the complete equipment model, serial information and installed service reference.\u003c\/li\u003e\n\u003cli\u003eMatch K80-5001 in the actual service drawing.\u003c\/li\u003e\n\u003cli\u003eConfirm all three listed dimensions and end form.\u003c\/li\u003e\n\u003cli\u003eInspect keyway wear before selecting a key-only repair.\u003c\/li\u003e\n\u003cli\u003eConfirm the current supplied inventory and exact installation and final testing instructions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis offer identifies the shaft-key service item.
