Loctite 620 must be applied to the assembly screws for the aluminium housing:
- Clean the threads in the aluminium parts using a ¼” UNC tap.
- Use compressed air or similar to blow out all blind holes to remove all debris.
- If re-using hardware, thoroughly clean cap screw threads using a wire wheel or similar to remove
all residual thread retaining compound. If new hardware is being used, thoroughly clean all
threads using aerosol tool cleaner or similar.
- Apply a bead of Loctite 620 to each screw and to each female thread. Beads should be
approximately the size of a match head.
- Assemble the parts, using the “solid laminate” torque specified in Table 2-8.
Ensure fresh nyloc nuts are used.
