Securing:
unscrew the threaded rod nut (pos. 4) and take it out of its seat. Replace the rod (pos. 4) with screw (pos. 6), torquing it down
fully to the torque value shown in "Values Table Torque Setting Bolts p. 32", using an intermediate threadlocker. Dana Incorpo-
rated recommends LOCTITE 601.
For instructions on how to secure the coupling, see section "Assembly with coupling p. 17" (see Fig. 17).
Disassembly:
the first thing to do is remove the coupling. For instructions on how to do this, see section "Disassembling the coupling. p. 18".
Disassembling the coupling. Remove the anchor bolt (pos. 6), the backplate (pos. 3) and the seeger retaining ring (pos. 5) from
their relative seats.
Turn the backplate over (pos. 3) and return it to its seat in the gear unit female shaft, securing it by inserting the retaining ring
(pos. 5).
Insert 2 bolts (pos. 7) into the two threaded holes on the backplate (pos. 3) and screw them until they touch the machine shaft
(pos. 1). Now give them alternately one full turn each (see Fig. 18).
MACHINE SHAFT WITH NO SHOULDER
Assembly:
Lubricate the coupling seat (pos.9) on the gear unit female shaft (pos. 2), then take the coupling andinsert it into its seat without
tightening the bolts.
Align the axes of the gear unit female shaft (pos. 2) as much as possible with the machine male shaft (pos. 1), then bring the
two shafts together.
Slot them together without exerting too much pressure on each part.
To make sure the female gear unit shaft is tight against the machine shaft use a threaded rod (pos. 4) of an appropriate size.
Now insert the backplate (pos. 3), the inner retaining ring (pos. 5) and the backplate (pos. 8). Now when you tighten the threaded
rod nut, the two shafts will abut against each other (see Fig. 19).
