Section I
DRIVE INSTALLATION
OUTFITTING
1. JR, JF, & JSC — Find the desired mounting position
in Figure 1 and install air vent and magnetic drain plug
(packaged separately with basic drive). Also note and/
or mark the oil level plug location OR in the case of a
vertical mounting, refer to Appendix E for installation
of vertical stand pipe. If the mounting angle exceeds
the limitations shown in Figure 1, refer to Appendix F
to determine modifications necessary within the limits
illustrated therein. DO NOT fill drive with lubricant at
this time. Oil plugs are located on input housing half.
2. JR — Remove anchor brackets, housing flange fasteners
and rod end fasteners from tie rod kit and assemble
to drive as illustrated in Figure 2. Refer to Table 1 for
tightening torque (original fasteners may be discarded).

3. JR — The tapered bore hollow shaft is designed for use
with a TA Taper bushing for mounting on a driven shaft with
a straight outside diameter. Shaft tolerances for the driven
shaft are given in Table 1A. The minimum and maximum
driven shaft engagements, dimension “N” in Figure 3, are
shown in Table 2. The minimum engagement is necessary
for full bushing engagement; the maximum engagement is
only required if a thrust plate will be employed to remove the
drive from the driven shaft (see Appendix C for preferred
removal method).
