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).
