DISASSEMBLY
1. Remove the snap ring and sprag bushing retainer
from one end only.
2. Pull the inner race out. Examine the race for scoring,
wear or indentations caused by the sprag cams.
3. Use a screwdriver and mallet to remove the sprag
bushing from one end of the outer race. There are
four special cut-outs in the bushing for this purpose.
Be careful not to damage the bushing inside surface.
If a bushing’s inside surface is damaged or shows
wear, replace it.
4. Next, slide the sprag clutch out, inspect the sprag
clutch closely for abnormal wear, cracks, pitting or
corrosion. Check small clips for breakage or bright
spots; the signs of excessive wear. Unless the outer
race or remaining sprag bushing is damaged or
shows excessive wear, there is no need for further
disassembly. If disassembly is necessary, remove the
bushing according to the procedure covered in Step
No. three (3). All brake clutch assembly parts should
be thoroughly cleaned and inspected before assem-
bly.
ASSEMBLY
1. Press a sprag bushing into the outer race, using a
mechanical or hydraulic press. A flat plate of approx-
imately the same diameter as the bushing flange out-
side diameter should be placed between the press
and bushing during assembly to protect the bushing.
Be certain the bushing flange is against the shoulder
in the outer race.

I
The polished surfaces of the races and sprag cams
must be perfectly smooth to insure positive engagement
of the clutch. The slightest defect may reduce brake
clutch effectiveness, which may lead to loss of load con-
trol and result in property damage, personal injury or
death. It is generally recommended to replace the
entire brake clutch assembly if any component is defec-
tive.
