Part Description
BDL, 1-1/2" primary belt drive kit. Closed. E-start
8mm pitch. Without idler. With starter ring gear. Comes as pulley & belt kit only. Stock clutch can be re-used. 61-41 drive ratio. Note: See 506915 for the replacement 1-1/2" wide 8mm 132t. - belt. Note: The difference in belts between 65-78 and 78-83 FL, FX models is due to a minor difference in primary housing length. Available belts are therefore designated as a - (minus, slightly shorter / MCS 506915) or + (plus, slightly longer / MCS 970974) belt, although the number of teeth is identical.
