Important model and position check
Match the complete model designation, including any suffix. This belt fits the listed CS-505 application in the Dual 261921 drive-belt family. CS-506 and CS-506-1 use different drive belts; this FBM 13.9 listing is not for CS-506. It is the platter-drive belt, not a toothed pitch-control belt. Where the mechanism has a separate pitch-control belt, that belt is not included.
Installation
Disconnect power before servicing. Remove deteriorated belt residue, clean the motor pulley and platter belt path, and install without twisting. Follow the equipment service manual for access and routing. The photo represents the medium-flat belt profile; the supplied size is FBM 13.9.
