Additional cross-references associated with this assembly include 307085008, 08-10169 and 085008. Cross-references should be verified against the exact operator manual because commercial trolley systems have used different rails, chains and carriage assemblies across production generations.
Inspect the rail, chain, front idler, drive sprocket, door arms, release components and chain tension before installation. A damaged rail or incorrectly tensioned chain can cause premature failure of the replacement trolley.
Disconnect and lock out operator power, close and secure the door and relieve drive-chain tension according to the service manual before removing the existing assembly. After installation, verify trolley engagement, emergency-release operation, travel limits and required safety-reversal functions.
