About This Product
MCS mainshaft for five-speed Sportster gearboxes. It replaces OEM 35640-89. It fits 1991 to 2005 XL Sportster models. You fit this when you split the cases for a transmission rebuild. A worn mainshaft causes poor gear alignment and rough shifting. Check the end float and torque the fasteners to spec before you seal the cases back up.
Manufacturer part number: 991664.
