Understanding system diagrams helps technicians identify faults more efficiently.
Bearings, Shafts and Rotating Equipment
Rotating machinery requires careful inspection and alignment.
Technicians may inspect:
- Bearings
- Shafts
- Couplings
- Pulleys
- Gears
- Sprockets
- Drive belts

Incorrect alignment can cause vibration, premature bearing failure and excessive equipment wear.
Welding and Fabrication Skills
Some maintenance departments value technicians who have basic fabrication abilities.
Useful skills can include:
- Basic welding
- Metal cutting
- Grinding
- Drilling
- Bracket fabrication
- Pipe repairs
- Equipment modifications
These skills can be particularly useful for emergency maintenance and workshop repairs.
