Remarks:
1) Loctite 243 medium strength
2) Connection between crankshaft and flywheel must be degreased and oil-free
When inserting DG and P screws into an existing screw thread:
Insert the DG or P screw in the hole and turn counterclockwise until it gently drops into the hole in axial
direction.
Tighten the screw clockwise to the specified torque.
DG screws must always be tightened with a torque wrench.
This procedure ensures that the screw engages properly in the existing thread and does not form a new thread
and weaken the assembly.
Coat micro-encapsulated screws with Loctite 243 medium strength before refitting them.
Screwdriver speed when used in plastic material: DG and P screws max. 500 rpm.
Do not use an impact wrench to release or tighten screw connections.
Screws with and without locking serration must not be confused.
