Removing components
Before removing a component, clean it and its mounting location.
- Close the holes created when the component was removed.
- After removing a component, immediately close the ends of the fuel, oil and hydraulic lines with suitable caps or plugs.
- Seal the open ends of the oil passages with wedge-shaped, wooden plugs or easily visible plastic plugs.
- Immediately after removing a component, put it in its appropriate container, use an individual container to store the removed component and parts removed from it (tray).
- Before removing a component, prepare a workbench for its disassembly, a container for its storage, and markers or stickers to mark it.
Disassembly
Maintain extra cleanliness in the workplace. This requirement must be strictly observed when working on components of the brake, fuel or hydraulic system. If particles of dirt or rags get inside these systems, serious malfunctions can result.
Blow out all internal cavities, slots, oil passages and fuel passages with compressed air.
WARNING: Adequate eye protection must be worn.
For proper assembly of the unit, mark the mating surfaces with paint. Do not use a scriber or a cutter for this purpose, as this may lead to cracking or distortion of the nodes.
Wire or tape the mating parts together to prevent misassembly.
Attach tags to those parts that need to be replaced with new ones, as well as to those parts that need to be troubleshooted. Keep these parts separate from re-assembly parts.
Dispose of any part only after you have compared the old part with the new one and made sure they are identical.
