TA Removal Tool
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-Falk 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.
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.
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.
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.
