Motor pulley liftboard

Hello everyone , Is there an outer circlip holding the motor pulley on ? ive removed the grub screw, im guessing this is factory oem , ive yet to use a puller or heat my next step…im a 25yr motorcycle mechanic- but 1st belt drive board total drivetrain rebuild, these motor mount bolts are soft junk, now i have 2 sheared off studs to remove…any help will be extremely welcomed.thanks.

drilling it out is the best. Or cut thous off with Dremmel cut not to far use a flat head screw driver in between the cut and hit it with a hammer it should fall apart in 2 pieces
