24、n tools 5.1 General In order to facilitate the correct assembly of the inserts use the appropriate tools. It is necessary to use one tool by insert reference. 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
26、the locking zone of the insert or the component into which it is being installed.

Inserts installed in aluminium or magnesium alloy components shall be lightly smeared externally with a suitable compound to prevent galvanic corrosio
30、n if required on the assembly drawing. b) Fit into place and screw the insert by two turns into the component. c) Fit into place the screwing nose of the tool onto the keys, then screw the assembly into the threaded hole until the screwing nose mates the component surface as shown in Figure 1 a). d)
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. After broaching of keys, the component surface shall not show any distortion or cracks. Dimensions in millimetres 12X =0,130,75Y =0,250,75Key 1 Installation depth of the keys 2 Install

40、ert shall conform to Table 5 and shall be checked using a low third pitch diameter passivated stainless steel test bolt (see Table 5). Bolts shall not be lubricated. The test bolts shall be periodically checked for wear and damage, any bolt falling outside the tolerances in Table 5 shall not be used
41、 for this check. The sample size/frequency for this check shall be at the responsibility of the installer.
