{"product_id":"liftmaster-k75-33948","title":"LiftMaster K75-33948 MHS Disconnect Assembly Kit","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K75-33948 is the disconnect-assembly service kit identified in the documented MHS commercial-door operator parts arrangement. Match the exact operator and manual-disconnect configuration before ordering. This is a specific service assembly rather than a complete hoist, clutch shaft or general-purpose release conversion for every medium-duty operator. 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\u003eMHS service arrangement\u003c\/td\u003e\n\u003ctd\u003eMatch the K75-33948 disconnect callout.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther medium-duty models\u003c\/td\u003e\n\u003ctd\u003eRequire their own explicit service recommendation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClutch \/ output shaft\u003c\/td\u003e\n\u003ctd\u003eSeparate assemblies with distinct repair scope.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManual-release operation\u003c\/td\u003e\n\u003ctd\u003eRetain the exact approved disconnect and re-engagement procedure.\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\u003eInspect the disconnect mechanism, linkage and adjoining components before choosing a replacement assembly. Difficulty releasing or re-engaging the operator can involve wear, misalignment or door condition as well as the disconnect itself. Compare the actual mechanism with the correct MHS parts drawing rather than select from a generic release-kit photograph.\u003c\/p\u003e\u003cp\u003eDoor disconnect work must account for balance and support. Have a trained door technician secure the installation and follow the prescribed door position and release procedure before disturbing the mechanism. A new disconnect does not repair a damaged counterbalance system or make an unsupported door safe. Confirm current kit contents and verify manual operation, re-engagement and the operator’s required protection functions after repair.\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\u003eK75-33948\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent\u003c\/td\u003e\n\u003ctd\u003eDisconnect assembly replacement kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented model\u003c\/td\u003e\n\u003ctd\u003eMHS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eService reference\u003c\/td\u003e\n\u003ctd\u003eK75-33948\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage requirement\u003c\/td\u003e\n\u003ctd\u003eConfirm current disconnect components and attachment pieces\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 the K75-33948 disconnect callout.\u003c\/li\u003e\n\u003cli\u003eRequire their own explicit service recommendation.\u003c\/li\u003e\n\u003cli\u003eSeparate assemblies with distinct repair scope.\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 disconnect assembly kit.
