8. Check that the crimping amount (C) of the boot band is at 

the standard value.

Standard value (D): 2.4 

− 2.8 mm (0.09 − 0.11 inch)

<If the crimping amount is larger than 2.8 mm (0.11 

inch)>
Readjust the value of (W) in step 5 according to the 
following formula, and then repeat the operation in 
step 7.
W = 5.5 mm (0.22 inch) 

− D

Example: If D = 2.9 mm (0.11 inch), then W = 2.6 mm 
(0.10 inch).

<If the crimping amount is smaller than 2.4 mm (0.09 

inch)>
Remove the EBJ boot band, readjust the value of 
(W) in step 5 according to the following formula, 
and then repeat the operations in steps 6 and 7 
using a new EBJ boot band.
W = 5.5 mm (0.22 inch) 

− D

Example: If D = 2.3 mm (0.09 inch), then W = 3.2 
mm (0.13 inch).

9. Check that the boot band is not sticking out past the place 

where it has been installed. If the boot band is sticking out,
