Install Hydraulic Power Pack - Wesmar HD825 Series Operation And Installation Manual

is lifted up. To reduce leaking, install the safety
clamp around the soundome tube just above the
packing cap and tighten in place. This will keep
the soundome tube from slipping down when
lifting the hoist.
2. Clean flange surfaces of the seachest and hoist.
Place the neoprene gasket on the seachest flange.
3. Lift the hoist assembly and set it on top of
the seachest. Rotate the flange to coincide with
the hoist power pack and limit switches for easy
maintenance.
Alignment considerations:
a) Only DC power pack can be installed
on the hoist rack. The rack opposite the limit
switches is the only rack leg the power pack can
be attached to.
b) The AC power pack must be installed
on a bulkhead. The DC power pack can also be
installed on a bulkhead and not on the rack. Rotate
the hoist so the rack leg with the limit switches is
adjacent to the bulkhead that has the power pack.
This will avoid crossing the hydraulic lines.
4. Bolt the hoist flange to the seachest. Apply
ANTI-SEIZE on the bolt threads. Insert the bolts
from the bottom up. Use the lock washer and nuts
and tighten in place.
5. Tighten the packing gland cap bolts finger tight.
Use wrench and tighten each bolt one full turn,
repeat for a total of two turns.
NOTE: When the vessel is back in the water,
cycle the hoist up and down four times. Check
the packing gland for water. It is normal for the
packing gland to weep but not drip. Tighten if
necessary.
