Spindle-Brake Disassembly
NOTE: This procedure applies only to units with integral input
brake (2).
NOTE: For this procedure, use the Brake Assembly Drawing, which
will show the proper balloon numbers for the individual
brake components. In the following instructions, if the
number has a “-” between two numbers, it refers to the
Brake Assembly Drawing only and NOT the Torque Hub
Assembly Drawing.
NOTE: The Pressure Plug (12) requires a special tool for installa-
tion. It is not recommended to remove this plug unless it is
leaking. The plug is called a Koenig Expander. The installa-
tion tool is not supplied by Fairfield manufacturing, but
can be supplied by the manufacturer of the Koenig
Expander, Sherex Industries, or one of their distributors.
