5. Insert the chain connecting link in the chain ends and lock with
the spring clip (supplied with the connecting link).
When assembled correctly, the Split Taper Bushing Sprocket will
“float”, for maximum misalignment capability.
Ever-Flex Coupling Installation
1. Select the correct Ever–Flex Coupling
and Adapter Plate from page 6.
2. Attach the Adapter Plate to the
Torq/Gard mounting lugs with three
(3) Allen Flat Head Cap Screws
supplied with the adapter.
3. Mount the Ever-Flex half coupling on
the Adapter Plate with the eight (8)
Hex. Head Cap Screws supplied with
the Adapter Plate.
(Quantity 10 Hex. Head Cap Screws are supplied with Adapter Plate
400CAP9 and 800CAP10.)
Mounting The Torq/Gard
The Torq/Gard Clutch hub is machined
to its maximum bore diameter. Shafts
smaller than the maximum diameter are
accommodated with standard Browning
Torq/Gard Bushing Kits as shown on
page 6. The bushing kits are complete
with bushing, key and shaft set screws.
Note: Six (6) set screws are supplied in
four (4) lengths.
Warning: The correct length set screws
must be used as the clutch will not
release if the set screws extend beyond
the hub and hit the adapter mounting lugs.
The Torq/Gard Clutch can be shaft mounted from the adapter or
detector end of the hub. The required shaft set screw lengths vary
depending on the bushing selected. They will also vary in length if
used on the detector end in conjunction with the detector
mechanism.
Tables B, C and D include all set screw combinations for any
bushing or mounting option.
Example 1:
A TGC60 Clutch requires a .750 inch diameter shaft mounted on the
adapter end.
Selection: A Browning 60BU012 Bushing Kit is chosen from page 6.
The correct set screws from Table B (adapter end):
Qty. 2 .190-32UNF-2A x .50 Long
Qty. 1 .190-32UNF-2A x .19 Long (over key)
Example 2:
A TGC60 Clutch requires a .750 inch diameter shaft mounted on the
detector end with the detector mechanism.
Section: A Browning 60BU012 Brushing Kit.
The correct set screws from Table B (detector end):
Qty. 2 .190-32UNF-2A x .75 Long
Qty. 1 .190-32UNF-2A x .38 Long (over key)
NOTE: If the Bushing was used on the detector end without the
detector, the selection would be the same as Example 1.

1. Select the Browning Torq/Gard Bushing Kit from page 6.
2. Refer to tables B, C or D for the correct shaft set screws.
(3 required)
3. Slide the bushing with the mating key on the shaft.
Note: The use of LOCTITE C5 - Anti-Seize lubricant is
recommended to ease assembly of the bushing to the shaft
and the Clutch to the bushing.
4. The shaft length must be at least equal to the bushing length to
insure engagement of the Torq/Gard bearings. Limited shaft
lengths or high overhung load applications require additional
outboard bearing support. Browning Bushings are manufactured
specifically to fit the entire length of the hub which provides
additional support. Again, check Tables B, C or D to insure that
the correct length set screws are used and that they will engage
the shaft.
5. Apply Perma-Lok HM118 to the set screws and mating tapped
holes in the Clutch hub.
