2. Turn the freefall assembly on the opposite side, so the
bearing support capscrews (806) are facing up. Re-
move bolts securing bearing support (802) to freefall
housing (801).
3. Remove the springs (804) and freefall piston (803).
FREE FALL ATTACHMENT
The GH30B freefall assembly weighs approximately
250 lb (114 kg). Make certain lifting equipment has ad-
equate capacity. Using undersized or poorly maintained
lifting equipment may result in a dropped load, property
damage, injury or death.
Refer to Winch disassembly to remove the freefall assem-
bly from the winch.
Follow this procedure after the freefall assembly has been
removed from the support end housing (3).
1. Set the freefall assembly with the freefall ring gear (4)
up and remove retaining ring (38). Remove the free-
fall ring gear (4). Remove o-ring (29) and discard.

DISASSEMBLY
Remove retaining ring (38) from the center ring gear
bearing support BEFORE removing capscrews (806.) If
capscrews are removed before retaining ring, the retain-
ing ring will be forced out of the groove by spring force.
Dislodging of the retaining ring may result in serious per-
sonal injury and certain damage to hoist components.
CAUTION
The bearing support is under spring tension from the
freefall assembly brake springs. Loosen each bearing
support capscrews one turn at a time until spring ten-
sion is released.
CAUTION
It may be necessary to apply a very short burst of shop
air at the freefall release port to break free the piston
from the freefall housing. If this is done, ensure all per-
sonnel are clear of the piston path. Loosely bolt the
bearing support back onto the freefall housing and use
shortest possible burst of low pressure shop air.
CAUTION
