Hi Sheva99,
As mentioned above by Rodney and Mdu6, all parts are dry assembled only and will require disassembly and then reassembly with loctite in the appropriate locations.
When i am building i will lay the parts out on the bench when disassembled and i will clean the areas to be loctited with a soft cloth and a cleaning solvent like methylated spirit or similiar. This removes any oil left over from the machining process or other contaminants.
Hope this helps,
Cheers,
Ross
