INTRODUCTION
The TA removal tool (patented) 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 5407 thru 5608 . The kit can be ordered from your
Rexnord distributor by specifying
“TA Removal Kit - Part

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.

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 . Rotate the high-speed shaft until the tool hook
engages one of the slots in the nut .
