R  (step 3). 
R 
R  - To make sure that the hole in the braid cannot move with relation 
R  to the holes in the convoluted hose, use cable ties to prevent 
R  braid displacement, at each side and at a distance of approx. 10 mm 
R  (0.3937 in.) to 15 mm (0.5905 in.) from the hole (step 4). 
R  - Insert an applicable mandrel in the hole and solder the braid 
R  around the hole over a width of approx. 2 mm (0.0787 in.) to 3 mm
 (0.1181 in.) (step 4).
 - Only for conduit with halar sheath (step 5):
 Slide a heat-shrinkable sleeve E0718 over the drain hole. The 
R  heat-shrinkable sleeve must also have a drain hole.
 Shrink the heat-shrinkable sleeve.
 (2) Wire protection at conduit end
 (Ref. Fig. 004) 
R  At the end of the conduit and in the area of connecting parts or 
R  transitions, the cables and metal parts must not touch. 
R  You must thus protect the harness with a sleeve NSA937210MB, split, 
R  then rolled at least twice around the cable bundle and attached with
 lacing tape NSA8420 or ASNA5107 wrapping tape. 
R  You must hold the full bundle at the conduit outlet to prevent all 
R  movement.

 (3) Conduit end with backshell or end fitting assembling procedure
R  ____NOTE : If necessary, apply the locking procedure after you tighten 
R  the backshell. 
R  (a) For conduit without halar sheath (ABS0330, ABS0492, ABS0631, 
R  ABS0887B, E0469, E0560, NSA935805T and NSA935806T)
 (Ref. Fig. 005)
 With backshell (ABS0581) or with end piece and conduit fitting
 (ABS0513, ABS0519, ABS0582, ABS0584 and ABS1023): 
R  Select the conduit end fitting size in relation to the size of 
R  the screened convoluted conduit. 
R  - Slide the related crimping sleeve over the end of the conduit.
 - Slide the braid back over the convoluted conduit. 
R  - Shorten the conduit by length "A".
 - Select the applicable size for the expansion tool ICORE 16-0987
 (Refer to chapter: Wire protection tools - 20-25-52).
 This tool is used to enlarge the convoluted conduit for easy
 assembly with connecting part. 
R  - Insert the convoluted conduit up to the shoulder, on the 
R  connecting part.
 - Slide the braid over the shoulder (cut any frayed material at
 the braid edge).
 - Slide the crimping sleeve over the braid up to the stop on the
 connecting part.
 - Select the applicable size for the hydraulic/pneumatic crimping
 tool ICORE 16-0803 or ICORE 19600 or REMA 58006-00 (Refer to
 chapter: Wire protection tools - 20-25-52).
 - Crimp the sleeve with this applicable tool. 
R  - A gap of 0.4 mm (0.0157 in.) maximum between the sleeve and 
R  connecting part is permitted after crimping.
 - Protect the gap with DINITROL AV30 (Material No. 15-008). 
R  (b) For conduit with halar (E-CTFE) sheath (ABS0510, ABS0511 and 
R  ABS0887C)
 (Ref. Fig. 006)
 With backshell (ABS0327, ABS0581) or with end piece and conduit
 fitting (ABS0519, ABS0582, ABS0584 and ABS1023): 
R  - Slide the related crimping sleeve over the end of the conduit.
 - Shorten the E-CTFE braid by 10 mm (0.3937 in.)
 - Slide the braid and E-CTFE braid back over the convoluted
 conduit.
 - Shorten the convoluted conduit by 5 mm (0.1968 in.).
 - Select the applicable size for the expansion tool ICORE 16-0987
 (Refer to chapter: Wire protection tools - 20-25-52). 
R  This tool is used to enlarge convoluted conduit for easy 
R  assembly with the connecting part.
