Hoist Assembly - BRADEN CH400B Installation Maintenance And Service Manual

NOTE: Apply Loctite Marine Grade Antiseize compound
to all external fasteners before installation. These fasten-
ers are items 8, 9, 12, 23, and 30 shown in the main com-
ponents drawing, and the motor flange capscrew.
NOTE: A 5/8-inch and 3/4-inch 12 point 3/4-inch drive
socket for the 12 pt. capscrews is needed to service hoist.
5/8 socket part numbers – Snap-On IMD202A, Proto
3/4 socket part numbers – Snap-On IMD242A, Proto
The hoist drive subassembly must be assembled before
following this procedure.
1. If drum support (5) was removed, install the O-ring
(18) on the drum support and install the drum support
in the hoist drum using lockwashers and capscrews.
Torque the capscrews using a crisscross pattern to
250 ± 15 lb•ft (339 ± 20 N•m).
NOTE: A 5/8-inch 12 point 3/4-inch drive socket for the
12 point capscrews is needed. Snap-On and Proto
part numbers for this socket are given above.
2. Install the inner race of bearing (3) onto drum support
(5) and secure in place with retaining ring (6).
3. Pack the bearing (3) rollers and outer hub (1) with
NLGI #2 EP grease with a Lithium complex base that
meets or exceeds NLGI GC or GC-LB specifications.
Install the bearing outer race and rollers (3) in the out-
er hub (1).
4. Install a new O-ring (9) against the outer race of the
bearing.
5. Install the seal (7) in seal container (8) as shown be-
low. Install the seal container and seal into outer hub
and secure in place with retaining ring ( 2).

6. Secure outer hub with bearing and seal container in
place on the hoist side plate using lockwashers (10)
and capscrews (9). The outer hub should be posi-
tioned so that the grease fitting is at the 12 o'clock
position with the hoist mounting feet setting on the
ground. Torque capscrew (9) to the torque chart value
given in this manual for 5/8-inch bolts.

7. Set the side-plate with outer hub installed and the
drum side facing up on a surface capable of support-
ing assembled hoist weight (up to 4000 pounds or
1815 kg depending on hoist drum).
The hoist drum weighs 1,000 to 1500 pounds (455 to
680 kg). Ensure the hoist and rigging are rated for this
weight. Using a hoist or rigging with insufficient rating
may result in personal injury or death.
8. Grease bearing and seal surfaces on the drum sup-
port and carefully lower the drum onto the outer hub
bearing rollers and ensure it is properly seated.
The hoist drive weighs 565 pounds (256 kg). Ensure
the hoist and rigging are rated for this weight. Using
a hoist or rigging with insufficient rating may result in
personal injury or death.
9. Install 2 eyebolts in the hoist drive assembly 180 de-
grees apart. Lift the hoist drive and while it is sus-
pended, install a new O-ring (18) under the lower
flange of the drive and grease lightly. Carefully set the
hoist drive into the drum aligning the holes in the drum
with those in the bottom flange of the drive.
10. Install capscrews (30) and lockwashers (22) that se-
cure the hoist drive to the drum and torque to 250 ± 15
lb•ft (339 ± 20 N•m).
The hoist end plate weighs 315 pounds (143 kg). En-
sure the hoist and rigging are rated for this weight. Us-
ing a hoist or rigging with insufficient rating may result
in personal injury or death.
11. Install the motor end plate (19) onto the hoist drive.
Orient the end plate so that the brake release port is
at the 12 o'clock position if the hoist is a standard unit.
12. Install the ten capscrews (23) and lockwashers (24)
which secure the end plate to the hoist drive.
13. Install the two tie plates (1) between the two end plates
using the dowels in the end plates to align and position
the tie plates. Install the 24 capscrews (8) and lock-
washers (7) securing the tie plates to the end plates.
14. Torque the capscrews (23) securing the end plate (19)
to the hoist drive to 400 ±15 lb•ft (540 ± 50 N•m).
15. Torque the capscrews (8) securing the tie plates the
end plates to the value listed on the torque chart for
1/2-inch Grade 8 capscrews.
