4.1.7.2 Assemble Screw Connection Joint
The assembly is done in reverse of the disassembly. However, a few things must be noted before
assembly is begun.
NOTICE
• Remove old Loctite residue in the screw holes with a roll tap or forming tap
(Size 2 M4 the rest M3) for threads before assembling the joint to get the
correct torque on the new screws.
• Always use new pre-coated screws when possible. If you must assemble with
old screws, carefully clean the screws and add Loctite 243 to the screws
before assembly.
• Always replace the black flexible flat ring with a new one to maintain the IP
classification.
• Replace the wear rings if extensive wear or damage is shown
1. Orient the joints according to the marks (indicated by red arrows in the image below) and
gently push the two joints together.
