Spindle-Brake Disassembly
NOTE: This procedure applies only to units with integral
input brake (2).
NOTE: For this procedure, use Brake Assembly Drawing,
which shows proper balloon numbers for individual
brake components. In the following instructions, if
the number has a “-” between two numbers, it refers
to Brake Assembly Drawing only and NOT Torque
Hub Assembly Drawing.
NOTE: The Koenig Expander Pressure Plug (12) requires a
special installation tool. It is not recommended to
remove this plug unless it is leaking. The installation
tool is available from KVT Solutioneering Group
(http://www.kvt-koenig.us) or their distributors as of
