1. Press a sprag bushing into the outer race, using a
shop press. A flat plate of approximately the same
diameter as the bushing flange diameter should be
used between the press and the bushing during
assembly to protect the bushing. Ensure the bushing
flange is fully resting against the shoulder in the
outer race.
2. Turn the assembly over, with the sprag bushing
down, and install the sprag clutch into the outer race.
Ensure the sprag cams are all laying in the same
direction during assembly.
3. Press the remaining sprag bushing into the outer
race. Ensure the bushing is fully resting against the
shoulder in the outer race.
4. Install a sprag bearing retainer and retaining ring
onto one end of the inner race. Ensure the retaining
ring is fully seated in the groove.
5. Slide the inner race through the sprag clutch.
The inner race will have to be rotated in the free-
wheeling direction to start it into the sprag clutch.
If the inner race will not go through the bushings, the
bushings may have been damaged and may need
replaced.
6. Turn the assembly over, with the retaining ring down,
and install the second retainer and retaining ring.
Ensure the retaining ring is fully seated in the
groove.
7. Install the small retaining into the groove in the bore
of the inner race.

Ensure the retaining ring is fully seated in the groove
in the splined bore of the inner race. This retaining
ring keeps the brake clutch assembly correctly posi-
tioned in the center of the friction brake stack.
Binding of the brake or brake failure may occur if this
snap ring is omitted, which may result in property
damage, severe injury or death.
