The MED crankshaft pulley bolt is CNC machined from EN24T steel. The bolt is longer than standard to give a more positive location of the pulley on the crankshaft, with an in-built washer.
See the MED Heavy Duty Flywheel Bolt for the fixing on the opposite end of the crankshaft (pre-Verto setup).
In place of the lock washer, we recommend to apply a drop of 27-01 thread lock and torque to 70lb/ft.
