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 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 .
2 .
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 driven shafts are shown in Table 1 . The minimum
and maximum driven shaft engagements, dimension
N in Figure 2, 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) .
