INSTALLATION
TABLE 1
1. Before mounting, ensure Cylinder (Item 10) has
adequate clearance to move freely (See Figure 1 and
Table 1).
2. Remove any dirt, grease, or foreign material from
the Friction Disc Hub (Item 1) bore and the tapered
surfaces of the Q.D. Bushing.
NOTE: Do not use lubricants when installing
Q.D. Bushing.
Do not strike Q.D. Bushing to “set” it in the bore
of the Friction Disc Hub.
3. Slide Q.D. Bushing into the bore of the Friction Disc
Hub (Item 1) (See Figure 2).
4. Insert cap screws into Q.D. Bushing, aligning them
with the tapped holes in the Friction Disc Hub (Item
1) (See Figure 2).
5. Position TSE Brake on the shaft (See Figure 2).
NOTE: There should be an 1/8 - 1/4" gap between
the Q.D. Bushing flange and the Friction Disc Hub
after the cap screws have been tightened to the
recommended torque.
Runout is minimized if a Dial Indicator is used as
the Q.D. Bushing cap screws are tightened. Place
contact tip of Dial Indicator on smooth surface of
the Friction Disc Hub (Item 1) to measure runout.
Runout on this surface must not exceed 0.005 TIR
when cap screws are tightened (See Figure 2).
6. Alternately and evenly tighten Q.D. Bushing cap screws
to the recommended torque (See Table 2).
NOTE: Keep torque pin as short as possible.
7. Secure brake Spring Housing (Item 4) to prevent
rotation and take up brake torque. A torque pin slot
is provided in the Spring Housing flange (See Figure
2).

CAUTION
Do not flange mount TSE Brakes.
Bearing preload will result after bushing
is installed and premature bearing
failure will ensue.

Do not install bolts into the threaded holes
of the Q.D. Bushing. The threaded holes
in the Q.D. Bushing are only used for
removal of the Q.D. Bushing.
