7.1: Removing the Rear Modular Dropouts from the Swinging Arm.
Tools Required:

7.1.1: From E-120

Reference figure 18. Both Left (4) and Right Hand (2) dropouts are a modular design, that
can be replaced if damaged. They are each attached to the Swinging Arm (3) by two bolts
(1a & 1b) . To remove either Right Hand (2) or Left Hand (4) dropout apply heat to the
assembly - to reduce the Loctite strength - then using the 5mm Allen key for the outside
bolts (1a) and 6mm Allen key for the Inside Bolts (1b), undo both bolts and remove them
from the assembly. The Dropout (2 & 4) should now be detached from the Swinging Arm
(3). Take care not to loose any of the components & also handle hot parts with care.

7.1.1: From T-120 or 146

Reference figure 19. Both Left (2) and Right Hand (3) dropouts are a modular design, that
can be replaced if damaged. They are each attached to the Swinging Arm (4) by three cap-
screws (1) . To remove either Right Hand (3) or Left Hand (2) dropout apply heat to the
assembly - to reduce the Loctite strength - then using the 6mm Allen key undo all three
bolts and remove them from the assembly. The Dropout (2 or 3) should now be detached
from the Swinging Arm (4). Take care not to loose any of the components & also handle
hot parts with care.
7.2: Assembling the Rear Modular Dropouts onto the Swinging Arm
Tools Required:

7.2.1: To E-120

Reference figure 18. It is important to make sure the Swinging Arm (3) and Dropouts (2 &
4) are clean and free from mud, grease and other dirt, which could prevent the Dropouts
(2 & 4) and Swinging Arm (3) from fitting together perfectly. Before assembling the bolts
(1a & 1b), apply a small amount of Loctite 638 retaining compound to the threads of each
of the bolts (1a & 1b), as well as to the outside of the Female Chain Ring Bolts (1b) so an
even covering is achieved. Next, assemble the parts as shown in Fig 17. making sure the
Bolts (1a & 1b) are correctly positioned as shown. Using the Torque Wrench, tighten the
bolts (1a & 1b) to the correct torque as specified in Section 8.0. Wipe off any excess re-
taining compound.

7.2.2: To T-120 or 146

Reference figure 19. It is important to make sure the Swinging Arm (4) and Dropouts (2 &
3) are clean and free from mud, grease and other dirt, which could prevent the Dropouts
(2 & 3) and Swinging Arm (3) from fitting together perfectly. Before assembling the screws
(1), apply a small amount of Loctite 638 retaining compound to the threads of the screws
(1) and Swinging Arm (3). Next, assemble the parts as shown in Fig 18. making sure the
screws (1) are correctly positioned as shown. Using the Torque Wrench, tighten the screws
(1) to the correct torque as specified in Section 8.0. Wipe off any excess retaining com-
pound.
