Installation
Remove your current bolts and nuts completely.
Place the bolt covers into their specific positions from the front, so they sit nice and flush with crank
Then use provided short bolts with torx T30 sockets and screw them from the back
While tightening the provided bolts to the recommended torque, it is necessary to prevent the bolt covers from spinning, by holding them down with your fingers
If the covers are not held while torqueing the bolts, they might get damaged
You should use about 5-7Nm of force. You MUST use medium strength thread locker on the bolt threads. (for eg. Loctite 243)
