FRAME MOUNTED TCB
REFER TO FIGURES 1-4.
1. Install Stud Bolts (Item 9) into a mounting bracket that
has been machined with 3/4-10 UNC tapped holes.
Tapped hole location requirements are:
TCB-10 2 holes @ 180 o on a 12-1/8" B.C.
TCB-14 3 holes @ 120 o on a 15-1/2" B.C.
TCB-20 4 holes @ 90 o on a 21-9/16" B.C.
NOTE
An alternate method for mounting this unit is to
secure the Stud Bolts by using angle brackets
located at the proper angles.
2. Secure Stud Bolts (Item 9) using Jam Nuts (Item 10).
3. Install an Elbow Fitting (Item 15) or a Tee Fitting
(Item 16) as required into each caliper half.
4. Using Lock Washers (Item 19) and Cap Screws
(Item 18), secure one-half of a Caliper Assembly to
the flange side of the Housing (Item 8). Tighten the
Cap Screws to 7 ft-lbs [9.5 Nm] torque.
NOTE
Internal springs return the Caliper Piston to the
disengaged position to guarantee clearance
between Friction Facing and Rotor when no air
pressure is being applied. The use of this spring
is optional; the low air pressure setting is more
sensitive without the springs. Refer to PARTS
REPLACEMENT for spring removal.
5. Install a Jam Nut (Item 10) onto each Stud Bolt (Item
9) and place Housing (Item 8) on Stud Bolts.
NOTE
Provide a minimum clearance of 3" between both
sides of Housing (Item 8) and other machine
components.
6. Secure Housing (Item 8) to Stud Bolts (Item 9) with
remaining Jam Nuts (Item 10).
7. Using the Machine Screw provided with each
Friction Facing, secure a Friction Facing to each
caliper. Tighten screws to 10-19 in-lbs [2.0-2.1 Nm].
8. Install rotor Hub (Item 1).
NOTE
See Page 4 for ROTOR HUB installation.
