Odd, how would one know how far to screw them in?
I just looked at the instructions in the kit. Step 21 says: "(Refer to Service Manual) Check rudder for proper deflection and direction of travel when operated by the rudder pedals.
Adjust 0433142-1 Stop Bolt as required . Tighten MS21042-3 Nut to secure adjustment of stop bolt".
The mechanic might have done that while I was in the cockpit removing the instrument panel cover to install the oil temp gauge.
