Recommended Bolt Torque - BRADEN CH280 Installation Maintenance And Service Manual

10. Install the eight capscrews and lockwashers (Items 51
and 52) through the brake cylinder into the motor end
plate. Loosely tighten all capscrews until they are snug
against the motor adapter. Continue to tighten the
capscrews in a crisscross pattern onto turn at a time
until the motor end plate is drawn up tightly against
the brake cylinder. Torque capscrews to their correct
value.
11. Install the two tie plates (Item 61) between the two
end plates of the hoist, using all 20 BRADEN SPE-
CIAL capscrews and lockwashers (Items 60 and 52).
Be sure the curved sides of the tie plates are toward
the top of the hoist. Torque all capscrews to their cor-
rect value.
12. Install the overrunning clutch assembly into the center
of the brake pack. Refer to Page 26 for correct orienta-
tion. Input spline side, shown on Page 26, is the end of
the clutch facing outward, toward the motor. It may be
necessary to rotate the drum slightly in either direction
to align the clutch splines with the input sun gear. The
internal retaining ring in the clutch should be seated
against the input sun gear when correctly installed.
Higher or lower torques for special applications will be specified such as the use of spanner nuts, nuts on shaft ends,
jam nuts and where distortion of parts or gaskets is critical.
Lubricated torque values based on use of SAE 30-wt engine oil applied to threads and face of bolt or nut.
Avoid using thread lubricants as the applied torque may vary by 10 - 40%, depending upon the product used.

13. Lubricate and install a new O-ring onto the hydrau-
lic motor pilot. Engage the motor shaft with the inner
race of the overrunning clutch and lower the motor into
place. Install motor capscrews and lockwashers and
torque to correct value.
14. Install all hydraulic lines disconnected during disas-
sembly, then tighten all connections.
15. After the hoist assembly is complete, check all cap-
screws and fittings to make certain they have been
properly installed and tightened correctly. Refill the
hoist with the recommended oil listed in Recommend-
ed Gear Oil section of manual.
16. Before returning the hoist to full service, a light load
should be lifted and held a few feet off the ground to
be sure the static brake is functioning properly. The
hoist should also be able to slowly lower the load in
a smooth and controlled manner. If the hoist does not
perform either of these functions correctly, refer to
Troubleshooting section for additional information.
