The CSW200U repair-parts drawing lists this reference as the top gearbox assembly, separate from the lower gear reducer and output shaft. Choose it for a repair whose exact operator documentation calls for this complete part number. The #70 designation is an assembly identifier, not a stated 70:1 reduction ratio. Confirm the operator generation, mounting and required kit contents before ordering.\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\u003eCSW200U\u003c\/td\u003e\n\u003ctd\u003eManufacturer drawing identifies K75-50224 as the top gearbox assembly.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther CSW200 generations\u003c\/td\u003e\n\u003ctd\u003eConfirm this exact service number; do not assume every older Elite gearbox is the same.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQ216 output-shaft kit\u003c\/td\u003e\n\u003ctd\u003eA separate service item; shaft-only replacement and gearbox replacement are different repair scopes.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eK32-34655-1 CSW24 top gearbox\u003c\/td\u003e\n\u003ctd\u003eA different service reference; similar location does not establish interchangeable fit.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLower gear reducer\u003c\/td\u003e\n\u003ctd\u003eSeparately identified in the operator drawing; not the component offered here.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eConfirm Which Gearbox and Associated Parts Need Repair\u003c\/h2\u003e\u003cp\u003eA gate drive can contain more than one gear-reduction assembly. Identify the failed stage before ordering a top gearbox. Noise, excess movement or failure to transmit motion may also involve a shaft connection, chain, belt or arm hardware. A technician should inspect the complete drive rather than assuming all motion problems originate inside this assembly.\u003c\/p\u003e\u003cp\u003eDocument the operator model and the existing gearbox arrangement before disassembly. Older equipment may have undergone prior repairs, so compare the installed part with the correct service drawing. Check the output-shaft and mounting condition at the same time.
