8. Check that the crimping value of the boot band (C) is equal to the standard value.

   Standard value (C): 2.4 to 2.8 mm (0.10 to 0.11 in) 

   < When the crimping value is over 2.8 mm (0.11 in) > Readjust W in step   5  according to the following expression, and then perform the operation in step   7  again. 

   W = 5.5 - C (Example: W = 2.6 for C = 2.9)

   < When the crimping value is below 2.4 mm > Remove the boot band, readjust W in step   5  according to the following expression, and then perform the operations in steps   6  and   7  again using a new boot band. 

   W = 5.5 - C (Example: W = 3.2 for C = 2.3) 

9. Check that the boot band is seated within the installation area. If it is not seated within the area, remove the band and use a new band to perform the operations shown in steps from  6 to  8.
   CAUTION:

   • The special grease is used for the joint: Do not mix old and new grease, or grease in different types.

15. Check that the crimping value of the boot band (F) is equal to the standard value.

    Standard value (C): 2.4 to 2.8 mm (0.10 to 0.11 in) 

    < When the crimping value is over 2.8 mm (0.11 in) > Readjust W in step   12  according to the following expression, and then perform the operation in step   14  again. 

    W = 5.8 - F (Example: W = 2.9 for F = 2.9) 

    < When the crimping value is below 2.4 mm > Remove the boot band, readjust W in step   12  according to the following expression, and then perform the operations in steps   13  and   14  again using a new boot band.
