In general, overhaul includes total disassembly of machine, exchange of bearings, seals, worn gear wheels, spindles, reinforcing of guideways with hardened steel plates (or their regrinding, if these are already on the machine), and their grouting with plastic material, complete machine geometry, replacement of covers, new electric installation and surface treatment. A necessary prerequisite is meeting the requirements of current legal regulations and technical standards, mainly in relation to the operational safety of the machine.
