SECTION 03 TRANSMISSION SUB-SECTION 05 (PULLEY DISTANCE AND ALIGNMENT)
PULLEY DISTANCE AND ALIGNMENT
GENERAL
The pulley distance we will refer to, in this section, is the space separating the drive and driven pulley outside diametersThis basic distance is provided as an assembly guide and indicates the dimensions between which satisfa ctory belt deflection will be obtainedBoth pulley distance adjustment and pulley alignment must be carried out to ensure the highest efficiency of the transmission systemFurthermore, the high drive belt operation and minimum wear will be obtained only with proper pulley alignment
Pulley distance specification

Pulley distance adjustment method
With the threaded rod and nut located between chaincase and frame, shift chaincase to obtain the specified distance
Pulley alignment specification
34 mm 75 (1 11 32" 1132)NOTE: tolerance up to 1.5 mm (116") is allowed on the offset measurement to compensate for the twist due to the drive pulley torqueRefer to the illustration
