TA Removal Tool
2. Loosen the setscrew on the O.D. of the bushing nut
and select the most convenient of the tapped holes in
the housing face for the threaded adapter. Figure 2.
INTRODUCTION
The patented TA removal tool offers a positive method
for removing a TA Taper equipped Quadrive from the
driven shaft. This method uses the torque multiplying
characteristic of the drive to separate the drive from the
bushing and driven shaft.
The removal tool is available in kit form suitable for use with
sizes 5107 thru 5315. The kit can be ordered from your
Rexnord distributor by specifying “TA Removal Kit - Part
0769406”. NOTE: Use of this tool requires a minimum axial
clearance “M” shown in Figure 1 and Table 1.
CAUTION: DO NOT modify the tool in any way OR use it
in another manner except to loosen the bushing nut as
instructed herein.
PREPARATION FOR REMOVAL
WARNING: Always “lock out” prime mover before working
on the Quadrive.
1. Quadrive shafts, input and output, must be free to
rotate.
a) Remove any external load on the driven shaft.
b) Remove belts from input shaft sheave.
c) Remove the backstop (if so equipped). Refer
to Section II — Step 10, for backstop removal
instructions.
CAUTION: DO NOT disconnect the drive from its
torque arm until the removal process is completed.
In addition, the drive must be supported during
removal process. Use a sling around the motor
mount or as recommended in Section I, Step 7.
Be sure to take up the slack in the sling before
proceeding.
3. Select the proper adapter from the tool kit (adapters
are marked with the Quadrive Size and part number).
Make sure the tapped hole in the housing face is
clean before inserting the adapter. Apply tightening
torque from Table 2.

TOOL
4 Mount the removal tool as illustrated in Figure 3 or 4.
It is generally preferable to install the tool in a position
where its weight will tend to keep it engaged into
the nut. Then rotate the input shaft until the tool hook
engages one of the slots in the nut.
