Logan 85-Ton Open Loop Power Swivel
MAINTENANCE
The following guidelines are intended
to ensure maximum life of the Logan
85-Ton Open Loop Power Swivel.
These are recommendations only.
Extreme peak load usage, temperature,
and other variables will affect suggested
service intervals.
Power Swivel Maintenance
Lubrication
1. Check the gear lubricating oil prior
to service. The oil level should be
maintained at the oil level plug level
at all times. If necessary, bring oil to
the proper operating level by adding
Logan Gear Lubricant (Part No.
G14085-001). Some lubricating oil
may leak out when the oil level plug
near the top cover plate is removed.
If oil does not leak out, gear lubricat-
ing oil of proper type and grade
should be added to the correct oper-
ating level.
2. Gear lubricating oil should be
changed after the first 100 hours of
initial operation. Check the magnetic
drain plug for metal filings when
changing the gear lubricating oil.
NOTE:
Oil capacity of the Logan 85-
Ton Power Swivel is eight (8) quarts.
3. After the initial break-in period (first
100 hours of operation), the gear
lubricating oil should be changed
after each 1,000 hours of operation
thereafter, or if the unit has been out
of service for an extended period.
Always check the magnetic drain
plug for metal filings when changing
the gear lubricating oil.
4. Regularly subject the elevator bail,
stem, and saver subs to magnetic
particle inspection.
Breaking-In
During initial break-in, or after a long
period of idleness, run the Power Swivel
with a reduced load at slower speed
until it reaches normal operating tem-
perature ranging between 120 – 200°F.
A somewhat higher operating tempera-
ture is permissible in very hot climates,
provided that it increases gradually.
Storage
If the Logan 85-Ton Open Loop Power
Swivel must be stored, it should be
completely filled with gear lubricating oil
to prevent oxi-dation. Thread protectors
or lift plugs should be installed on stems
or saver subs to prevent damage to the
threads. Grease or dope the threads
before installing the thread protectors or
lift plugs.
Open gear housings, ports, and re-
moved motors should be covered with
clean drop cloths to prevent dirt and
trash from entering internal mecha-
nisms. Before shipping parts for service,
all openings should be sealed and parts
wrapped in clean, heavy kraft paper.
Replacing the Floating Washpipe
Assembly and Packing
The entire Floating Washpipe Assembly,
including the upper and lower packing
nuts, can be removed from the swivel
without removing the gooseneck or
bonnet.
Remove the four retainers and retain-
ing screws from the lower packing nut.
Loosen the lower packing nut by turning
it in a clockwise direction until it turns
freely. Secure the upper stem to keep
it from rotating while loosening and
removing the lower packing nut. Use
the same procedure to loosen and
remove the upper packing nut from the
gooseneck.
Remove the washpipe and packing
assemblies. Press the washpipe out
of the lower packing nut and slide the
upper nut off. Remove the three upper
packing locking pins and press the up-
per packing off the washpipe. Replace
the washpipe if it shows any signs of
wear (i.e., scoring or surface abrasion).
The average life expectancy of the
packing is 200 – 250 hours. Remove
the old packing from the packing nuts.
Thoroughly clean the inside of both
nuts. Using the drawing on page 8 as
a reference, install the new packing.
Assemble the packing and floating
washpipe assembly in reverse of as-
sembly procedure. Tighten the packing
nuts securely, locking them in place with
the retaining screws and retainers.
Power Unit Maintenance
The Power Unit includes the engine,
piping, filters, reservoir, hoses, hose
reels, cables, electrical components,
and gauges.
Engine
Please refer to the specific engine man-
ufacturer’s maintenance instructions
included with your documentation.
Hydraulic Oil and Filters
The hydraulic fluid reservoir (Logan
Part No. PS06206) should be main-
tained at the proper level at all times.
The oil level should be visible in the
sight gauge when cold.
Filters
The return filter located at the top of the
reservoir should be replaced when the
pointer indicates that it needs cleaning.
The indicator registers when the engine
is running.
The high pressure filter in the pres
-
sure line should be serviced when the
condition indicator displays red. Green
indicates that the filter is in satisfactory
condition. The filter indicator operates
when the swivel is rotating to the right.
