The tools and their methods of application described in this standard are not mandatory and show only the basic principles to be observed to

25、achieve the satisfactory installation and subsequent broaching and the satisfactory removal of the inserts. The maximum dimensional requirements provided shall be achieved and on no account shall the design of the tools or their methods of application be such that damage may occur to the threads or

31、 Adjust the insert position within the X limits given in Figure 3. e) Turn the tool on the broaching nose side as showed in Figure 1 b). f) Apply a sufficient load in the direction indicated Figure 1c to broach the keys by stamping or by pressing on the tool. The keys are fitted in the proper positi

32、on corresponding to Y dimension given in Figure 3. g) Remove the tool from the insert. h) Remove excess sealing compound or lubricant if any. 5.3 Air pressure installation 5.3.1 Installation tool Figure 2 illustrates a tool for screwing, broaching and unscrewing assembled on an air pressure gun.

35、e insert with the lubricant referenced on the assembly drawing. Inserts installed in aluminium or magnesium alloy components shall be lightly smeared externally with a suitable compound to prevent galvanic corrosion if required on the assembly drawing. b) Screw the insert on to the threaded mandrel

36、until it is fully seated on the installation nose. c) Using the tool, screw the insert into the tapped hole until positioned: The screwing/broaching tool comes into contact with the surface of the component, when operating the air gun. The insert comes in position as shown in Figure 3 below the surf

37、ace of the casing. d) Use the air gun in the percussion mode to broach the keys. e) Unscrewing is automatic to extract the tool from the crimped insert. f) Remove excess sealing compound or lubricant if any. 6 Checks of insert position and keys broaching These checks shall be carried out with an ins

38、pection gauge common to all insert dimensions. Check dimensions X and Y which shall be in accordance with Figure 3.
