ASSEMBLE DRIVE SHAFT
Black-out System Installation
1. For each span between the rack drives, measure the distance from the
insides
of the drive couplers. See diagram.
2. Once this distance is determined, locate a section of 1.315" pipe (131S147), and cut to this measurement. Verify
that the PLAIN end of the tube is used, and NOT the swaged end. Repeat for each coupler-to-coupler section.
3. Once all drive shaft sections have been measured and cut, REMOVE the rack drives from the power rafter.
4. Loosely set the drive shaft pieces into the corresponding rack drives (temporarily secure with Tek screws if
necessary), and then lift and slide the loosely assembled drive shaft components back into the motor couplers from
either side.
ASSISTANCE WILL BE REQUIRED!
5. Reattach the rack drives to the power rafter, and tighten the lock nuts. Do not secure drive shaft to the couplers at
this time.

Measure this distance.
Measure from the insides of the
couplers, located approximately
2-1/2" inches in from the second
splice hole, as shown.
ATTENTION:
If necessary to splice the drive shaft at a swaged/plain
connection point, do so using two (2) 5/16"x2" bolts (FAG334B), four (4)
5/16" flat washers (FAME07B) and two (2) 5/16" lock nuts (FALF37B).
