General recommendations when performing locksmith work (Range Rover 3)

Removing components

Before removing a component, clean the installation site.

• Close the holes created when the component was removed with process plugs.
• To prevent fluid from escaping and foreign particles from entering the system, immediately close the ends of the fuel, oil, and hydraulic lines disconnected during component removal. Plastic caps or corks are suitable for this.
• Seal the open ends of the oil passages with wedge-shaped, wooden plugs or easily visible plastic plugs.
• Immediately after removing the component, put it in an appropriate container, use an individual container to store the removed component and the 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. Particles of dirt or cleaning cloths can cause serious damage if they enter these systems.

• Blow out all internal cavities, slots, oil passages and fuel passages with compressed air. Replace any rubber O-rings damaged during disassembly.
• Mark mating surfaces with paint for proper assembly of the unit. Do not use a scriber or a cutter for these purposes - mechanical influences can cause cracks or damage parts.
• Fasten the mating parts with wire. This will prevent the possibility of incorrect assembly (e.g. roller bearing components).
• Using wire, 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.
• Never dispose of components before purchasing new parts. Only after making sure of their identity, you can dispose of the old part.

Detergents

Use only recommended detergents or equivalents to wash parts. If volatile substances are used for cleaning, ensure that the workplace is well ventilated. If the units contain components that can be damaged by detergents, then their use should be discarded.

Inspection

Before reassembly, all components must be carefully inspected for signs of wear and damage.

• Inspection of components should only be carried out after they have been thoroughly washed. Even minor oil stains can hide incipient defects.
• If it is necessary to measure the dimensions of a part in order to compare its dimensions with the allowable dimensions, then an appropriate measuring tool should be used (Johansen tiles, micrometers, dial gauges). Make sure that the measuring tool and fixtures are checked and in good condition.
• If the dimensions of the part are outside the limit values or the part shows signs of damage, then it is subject to rejection.
• A part is considered fit for reinstallation if its dimensions are within the established tolerances and it does not show signs of damage. To measure plain bearing clearance, use 'Plastigauge' 12, type PG-1.
