SIZE 4407(FIGURE 2)
— Assemble backstop cage, Ref.
#20, onto studs using one new .015" (0,38 mm)
shim-gasket, Ref. #30, against the housing. Slide the spacer,
Ref. #5A2, into the backstop cage up against the bearing
cup. Align the key with the keyway in the backstop cage and
gently slide the backstop into the bore while slowly rotating
the shaft from the drive side of the drive. The shaft will only
rotate in one direction. Check to determine if the shaft
rotation is as required. If not, gently remove the backstop;
turn it around, and reinsert into the bore as instructed
above. Go to Step 6.
5.
SIZE 4415 THRU 4507 —
Install dowel into cage.
a) Size 4415J14 & 4507J14(Figure 3) — Install backstop
and key into backstop cage allowing the backstop to
protrude from cage 0.25" (6,4 mm). Coat spacer with
grease to assist in holding the spacer against the
backstop for assembly and insert into drive side of cage.
b) Size 4415J25 & 4507J25(Figure 4) — Assemble one
retaining ring in groove on backstop. Slide backstop and
key into backstop cage and assemble other retaining ring
on backstop to hold it in the cage.
c) Size 4415 & 4507(All types) — Place one new .015"
(0,38 mm) shim-gasket, Ref. #30, against housing.
Carefully install the backstop/cage assembly on the
oiled shaft extension. Rotate the high speed shaft while
sliding on the assembly. The shaft will only rotate in
one direction.
DO NOT FORCE OR HAMMER; this may damage the
shaft or misalign the sprags.
d) Check operation of backstop by turning input shaft in
required direction of rotation by hand. If the shaft does
not rotate in the required direction, remove backstop,
reverse it and reinstall as instructed in preceding steps.
6. Rotate input shaft in the required direction of rotation and
then reverse the rotation to lock up the backstop. Observe
the position of the sprags. All Sprags must be engaged and
lay in the same relative position around the shaft. If the
sprags are not uniformly positioned, lightly tap the backstop
cage to centralize all the sprags around the shaft and cage.
If sprags cannot be uniformly positioned in this manner,
remove the backstop and run a finger around the sprags in
the overrunning direction. Reinstall backstop as instructed in
the preceding steps.
Check the position of the sprags several times by
overrunning and locking the sprags. If all sprags move
uniformly, hold the backstop in the locked position and
proceed to the next assembly step.
7. Install backstop cover, shim-gasket and fasteners, Ref. #19,
29 & 38. Tighten fasteners to 825 lb-in (93 Nm) for Size
4407, and 330 lb-in (37 Nm) for Sizes 4415 - 4507.
8. Clean housing surface for rotation and warning labels. Affix the
rotation indicator next to input shaft extension to indicate the
free direction of rotation, Figure 5. Fill drive to oil level specified
in Section I, Table 9, with oil specified in Appendix A. Check
motor for correct rotation before completing connection to
drive.
WARNING:
Refer to Appendix A for lubricant restrictions. Use
of an improper lubricant will contribute to premature wear or
malfunction of the backstop.
