— (NOTE: If the driven shaft has not been machined
to Falk’s taper bore specifications per Manual 377-140
and a straight shaft is to be utilized, refer to Manual
377-144 for instructions) .
Install backstop prior to installation of drive (refer to
Appendix B) . Installation of internal backstops NOT
Factory-installed may require removal of mounting
flange, Ref . #12 . Remove cover from input end of hollow
shaft bore and save . Install the thrust plate and retaining
ring in the hollow shaft (refer to Figure 4) . Proceed to
Step 6 .
INSTALLATION
6 .
JR, JF & JSC
— Refer to Figure 7 for recommended
lifting method . In order to sling JR & JF drives as
illustrated, install the torque arm fastener in the torque
arm anchor brackets . Sling the drive from the fastener
as shown . For vertical installation, use (3) eyebolts as
illustrated . Eyebolt sizes are 1/2” for 5407 thru 5507
and 3/4” for 5608 . DO NOT remove sling until drive is
secured to shaft . Before lifting the drive into position,
rotate the high-speed shaft until the hollow shaft keyway
will be in position to line-up with the driven shaft key . JF
proceed to Step 11; JSC to Step 12 .

JR
— If the drive was received with a backstop
installed, the backstop must be temporarily removed
to facilitate mounting . Refer to Section II, Step 10 for
backstop removal instructions . Proceed to Step 8 .

JR
— Lift the drive into position and slide onto the drive
shaft taking care that the driven shaft key seats into the
hollow shaft keyway . DO NOT hammer or use excessive
force . Refer to Figure 8 for installation of the torque arm .
The exact position of the torque arm may vary within
the range shown . For torque arm mountings other than
shown, refer to Factory . If it is necessary to shorten the
torque arm assembly, cut the excess from either tie rod
end .
The support to which the clevis bracket is to be
fastened must sustain the torque reaction shown
in Table 4 . The maximum load reaction through the
torque arm occurs when the torque arm is located in
the extreme off angle position . Use Grade 5 fasteners
to anchor the clevis bracket; refer to Table 5 for the
fastener size and tightening torque .
Bolt the torque arm to both the clevis bracket and the
drive anchor bracket and tighten the bolts until seated
against the brackets . DO NOT bend the bracket as
clearance between the clevis brackets and tie rod is
necessary .
