62.Place two pieces of about 10mm long, 3mm 

diameter solder on the converter housing at the 
locations indicated in the drawing.

63.Use the special tools to drive the outer race into 

position.

• Installer adapter (MB990935)

• Handle (MB990938)

64.Install the converter housing on the transmission 

case without applying FIPG. Tighten the mounting 
bolts to the specified torque of 48 

± 6 N⋅m.

65.Remove the bolts and converter housing, and 

take out the solder pieces.

66.Use a micrometer to measure the thickness of the 

crashed solder.

67.Select a spacer of the thickness equivalent to the 

micrometer reading plus the standard preload 
value.

Standard preload value: 0.045 

− 0.105mm

68.Install the spacer selected in step 67. into the 

converter housing and drive the outer race into 
position using the special tools.
