{"product_id":"liftmaster-041b0139","title":"LiftMaster 041B0139 Motor Vibration Isolator Bushing and Spacer Kit","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster 041B0139 is the isolator spacer kit used to isolate motor vibration in selected belt-drive garage door openers. The manufacturer identifies a set of isolator bushings and spacers and lists the 3280 application. Select it by the exact motor mounting arrangement; it is not a universal rubber mount or a complete replacement motor assembly. 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\u003e3280 belt-drive opener\u003c\/td\u003e\n\u003ctd\u003eManufacturer-listed application; verify installed revision.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther belt-drive models\u003c\/td\u003e\n\u003ctd\u003eRequire their own explicit service match.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor mounting\u003c\/td\u003e\n\u003ctd\u003eCompare the original bushing and spacer positions.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComplete motor replacement\u003c\/td\u003e\n\u003ctd\u003eThis kit does not identify a motor, bracket or drive rebuild.\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\u003eWorn or missing isolators can affect the intended motor mounting arrangement, but vibration can also come from a damaged drive, loose housing or a door that does not move freely. Have the complete system checked before assuming that new bushings alone will resolve noise or movement.\u003c\/p\u003e\u003cp\u003eThe bushing and spacer arrangement must preserve the manufacturer’s mounting geometry. Do not replace the specified parts with improvised rubber washers or tighten the assembly according to a guessed compression amount. Compare the exact service instructions and current package so every required isolator and spacer is installed in its intended location.\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\u003e041B0139\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eMotor vibration isolation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIdentified contents\u003c\/td\u003e\n\u003ctd\u003eSet of isolator bushings and spacers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented model\u003c\/td\u003e\n\u003ctd\u003e3280\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAlternate reference\u003c\/td\u003e\n\u003ctd\u003e41B0139\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\u003eIdentify the complete opener model and motor arrangement.\u003c\/li\u003e\n\u003cli\u003eConfirm the 041B0139 service match.\u003c\/li\u003e\n\u003cli\u003eInspect the mounting points and surrounding drive for damage.\u003c\/li\u003e\n\u003cli\u003eVerify the supplied bushing\/spacer set and installation instructions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThe manufacturer identifies a set of isolator bushings and spacers.
