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)
