{"product_id":"liftmaster-ma005","title":"LiftMaster MA005 Mega Arm Gear Reducer — 60:1","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster MA005 is a 60:1 gear reducer identified in the documented Mega Arm barrier-operator drive. It is a separate mechanical component from the MA003 motor, belt and pulley assemblies. Select it by the complete operator revision and approved service reference rather than by reduction ratio alone. Shaft fit, mounting and the associated barrier-arm mechanism must match. Replacing the reducer does not correct a damaged arm, worn pulley connection or another fault elsewhere in the drive.\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\u003eDocumented Mega Arm assembly\u003c\/td\u003e\n\u003ctd\u003eManufacturer parts list identifies MA005 as the 60:1 reducer.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMega Arm Tower equipment\u003c\/td\u003e\n\u003ctd\u003eShared manual covers Tower configurations; confirm the installed drive reference.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther Mega-family revisions\u003c\/td\u003e\n\u003ctd\u003eNo universal fit established; use the specific operator diagram.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther 60:1 reducers\u003c\/td\u003e\n\u003ctd\u003eRatio alone does not establish shaft, mounting or load compatibility.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eInspect the Reducer and Its Drive Connections\u003c\/h2\u003e\u003cp\u003eBarrier movement passes through the motor, belt, pulley and reducer before reaching the arm mechanism.
