CHANGING EXTENSION SHAFT LENGTH
Extension shafts are available as 46 in., 47 in., and 50 in. lengths. (from centerline of drum to end of shaft).
The extension shaft is connected to the winch with a coupling that has two (2) sets of holes in it, 2 inches apart.
This allows the 46 in. shaft to be extended to 48 in., the 47 in. shaft to 49 in. and the 50 in. shaft to 52 in.
Follow the steps below to change the effective length of the extension shaft .
Remove the twelve (12) capscrews and lockwashers
securing the torque tube to the chain case, and slide the
torque tube toward the end of the extension shaft,
exposing the coupling. Remove the nut, washer and
capscrew that are furthest from the winch. Carefully
slide the extension shaft outward until the hole in the
shaft alignes with the outer hole in the coupling.
Replace the capscrew, washer and nut and torque to
the correct value. Slide the torque tube back against
the chain case and replace the capscrews and washers,
and torque to the correct value. Be sure the grease fit-
ting in the torque tube remains at the 12:00 o’clock posi-
tion.
The torque tube and extension shaft weigh approxi-
mately 65 LBS (29 kg). The entire assembly may
easily become disengaged from the coupling during
this procedure, resulting in personal injury. If neces-
sary, provide support for the torque tube and exten-
sion shaft as it is slid outward.
CAUTION
The capscrews used in the coupling are Grade 8.
DO NOT replace either of them with a soft bolt or
pin. A soft bolt or pin may shear off and cause a
sudden loss of load control which may result in
property damage, personal injury or death.

LEVEL WIND DRIVE CONVERSION
The level wind mechanism on the BP200 winch operates at a speed specific to the size of wire rope being used.
Whenever wire rope size is changed, some sprockets and chains will have to be changed for the level wind mecha-
nism to operate at the correct speed. The following table shows the correct sprockets and chains required for each
size wire rope.
Wire Rope Size 5/16 in. 3/8 in. 7/16 in. 1/2 in. 9/16 in.

BP200 Conversion Parts for Level Wind Drive
The following steps outline the procedure for changing the sprockets and chain to enable the level wind drive to
operate with a different size wire rope.
