D. Install the Wastegate Controller Conrod Fail-Safe Bridge
There are two procedures to secure the bolts on the Wastegate Controller to prevent rotation:

– By use of Nord-Lock washers under the head of the bolts.
If Nord-Lock washers are used to secure the bolts, use new Nord-Lock washer
every time the bolts are loosened.
Nord-Lock washers are for one-time use only!
