Service Parts Information:
Due to changes in the driven sprocket support for 1987, the new vespel (TM) oil seal rings and 4-lobe ring seals are not interchanged with the cast iron
oil seal rings on models built prior to 1987 start of production (SOP). Changes made to the driven sprocket support included deeper seal ring grooves
and "cutouts" to accommodate the ring tangs which prevent the vespel (TM) oil seal rings from rotating (refer to Figure 3).
The new vespel (TM) oil seal rings, 4-lobe ring seals and driven sprocket support are included in the following service package assembly and services all
model years:
