TA Removal Tool
Introduction
The TA removal tool (Patent Pending) 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 4407 thru 4608. The kit can be ordered from your Falk
distributor by specifying
“TA Removal Kit - Part 0769407"
.
NOTE: Use of this tool requires a minimum axial clearance
(”M" shown in Figure 1 and Table 1), from the seal cage stud.
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) when:
Type J05 input shaft rotation indicator is
counter-clockwise.
Type J14 & J25 input shaft rotation indicator is clockwise.
Refer to Section II — Step 10, for backstop removal
instructions.
WARNING:
DO NOT disconnect the drive from its tie rod
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 6, Page 6. Be sure to take up the slack in
the sling before proceeding.
2. Loosen the setscrew on the O.D. of the bushing nut. Remove
the most convenient seal cage nut and lock washer from the
stud. Figure 2.
3. Select the proper adapter from the tool kit. (Adapters are
marked with the Quadrive Size and part number). Thread the
appropriate adapter onto the stud and 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 it’s
weight will tend to keep it engaged into the nut. Rotate the
input shaft until the tool hook engages one of the slots in the
nut.
