|Threaded Joints - Course: Techniques of Fitting and Assembling Component Parts to Produce Simple Units. Trainees' Handbook of Lessons|
- Bolts and screws which have grown rusty should be treated with a suitable rust solvent, to loosen them.
- Bolts and screws which cannot be loosened despite the use of a rust solvent must be bored out. Bore when you have removed the head and the nut with a chisel.
- Where component parts are to be taken apart, all screwed joints should be loosened before the parts are fully dismantled.
- Use a suitable support for large parts which are to be dismantled so that they cannot drop onto the ground. Put the support in place before you unscrew the joints.
- Make sure that you remember the correct mounting position of parts which were removed for repairs.
Mark the parts suitably for re-assembly.
Use the right size of tools for disassembly work.
Beware that bolt threads or nuts are not damaged or you slip and cause injuries.
