{"product_id":"liftmaster-k87-p-075","title":"LiftMaster K87-P-075 Push-On Fastener —3\/4-Inch Designation","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K87-P-075 is the push-on fastener service reference identified with a 3\/4-inch designation in manufacturer commercial-operator parts information. It is a retention component rather than a bearing, washer or complete shaft kit. Match the exact shaft location and repair drawing before ordering. A fastener that appears to grip a shaft is not necessarily the specified retaining part, and the size designation alone does not establish fit for every3\/4-inch connection. Inspect the shaft and adjoining components before treating a new fastener as the whole repair.\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\u003eAssemblies specifying K87-P-075\u003c\/td\u003e\n\u003ctd\u003eMatch shaft and retention arrangement.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3\/4-inch designation\u003c\/td\u003e\n\u003ctd\u003eOnly one selection detail; exact fastener must match.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBearings or ordinary washers\u003c\/td\u003e\n\u003ctd\u003eDifferent components and function.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDamaged shaft or retention surface\u003c\/td\u003e\n\u003ctd\u003eRequires separate assessment.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReusing removed hardware\u003c\/td\u003e\n\u003ctd\u003eFollow exact manufacturer instructions; do not assume serviceability.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eInspect the Shaft and Retained Components\u003c\/h2\u003e\u003cp\u003eRecord the operator and photograph the fastener location before removing retained parts. Have the technician inspect the shaft surface, adjoining washer or bearing and the reason retention failed. A new push-on fastener cannot restore a worn shaft or a component that is moving because another support is damaged.

Avoid selecting a generic clip based only on approximate diameter, and do not assume a removed fastener can be reused. Support connected components while retention is disturbed.
