Installation:

The tightening torque (3.5 Nm) is reduced when special tool 51 3 310 is used. Depending on the torque wrench used, this must be calculated according to the adjacent equation:

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)

NOTE: If screwing is performed from the inside of the door (removed door trim panel), the tightening torque (without special tool) must be observed, see 51 37 SIDE WINDOWS, ELECTR. ACTUATED .
