Installation: 

The specified torque moment (MDE) (see 1AZ in 51 32 FRONT DOOR WINDOWS ) is reduced when using special tool 51 3 310 . Depending on the torque wrench used, this must be calculated in accordance with the adjacent overview:

MDE = Torque to be set

MDV = Prescribed torque (without special tool)

lj = Standard adjustment length with adjusting tool

l1 = Effective length of torque wrench

l2 = Inside dimension of adjusting tool

lw = Inside dimension of insertion tool (here lw = 145 mm)
