2.
Slide the TCB-7 onto the machine shaft (See Figure 1).

Tighten Set Screws (Item 3) to 7 Ft. Lbs. [9.5 N•m]
torque (See Figure 1).
NOTE: Runout of the Friction Disc Hub (Item 2)
must be less than 0.015'' [0.381 mm] TIR.
Runout is minimized if a dial indicator is used
as Set Screws (Item 3) are tightened. Place
