Disassembly & Assessment
1. GENERAL CONDITION
It is important to ensure the winch is safe to handle before work
commences. Firstly, inspect the condition of the housing and the drum
ensuring all fasteners are present and secure.
Any G.Winch units that:
- Do not pass basic function test.
- The winch body / frame is out of alignment, bent or damaged.
- Require stripping down of the winch body.
Are beyond the scope of this manual. These units should be returned
to Globestock for repair work to be assessed and completed. The
bodyalignmentisdicultandincorrectalignmentmaycausea
release of the lifted load during use.
2. INSPECT IDENTITY LABEL
This can be found on the side of the housing. Take note of the wire
rope length, material and maximum working load. Make sure the
label is legible and fully attached. If there is any damage the label
must be replaced.
3. INSPECT ROPE & KARABINER
To extract the rope, the pawl mechanism must be disengaged and
held to allow the drum to free spool. This can be clamped into
place, or the pawl stop can be removed, and the pawl lever pushed
beyond the return point.

Fully extract the wire rope inspecting for:

Inspect the karabiner making sure there are no signs of damage or
corrosion. The swivel function must rotate smoothly, and the gate
opens and closes without interference.
If the rope is to be replaced, remove the 4 screws from the rope
retaining plate and uncoil the rope from the drum. A new rope can be
ttedatreassembly.
4. INSPECT DRUM CONDITION
The drum must rotate freely, causing no interference with the winding

when rotating please refer to step 1 of reassembly
5. INSPECT BRACKETS (IF PRESENT)
Checkbracketstoensureallitemsarepresentandttedcorrectly.
Check all items are free from damage, corrosion, are in good working
order and function correctly. (Pay particular attention to the clamp
body lever thread location into the clamp body).

6. REMOVE AND INSPECT CLUTCH
COMPONENTS AND BRAKE LININGS
6.1 Remove the winch winding arm and check for damage and good
location into the handle holder. Ensure the wing screw is not
damaged and locks the winch arm in place when tightened.
6.2 Remove the 2 screws, handle holder and clutch shield plate.
6.3 Remove the 5 clutch cover screws and clutch cover. Inspect for
damage.
6.4 Remove the centre nut, washers and dodecagon washer.
6.5 Unscrew the clutch body. (If this is excessively tight and cannot

6.6 Remove the ratchet gear, centre bush and brake linings.
6.7 Inspect the brake lining thickness using a set of digital calipers.
Refer to table [X] on page [X] for minimum tolerance.
6.8 Inspect pawl tip for excessive wear and replace if necessary.

9.1 Ensure the base plate is correctly seated.
9.2 Clean down both brake linings with a dry cloth and apply a very
small amount of lithium-based grease to both surfaces (Ensure not
to apply too much grease as this will cause the brake to slip when
under load)
9.3Placetherstliningontothebaseplate.
9.4 Place the gear ring onto the lining, ensuring the correctly
orientation as shown.
9.5 Fit the brass ring into the centre of the gear ring.
9.6 Place the second lining onto the gear ring.
9.7 Apply a small amount of lithium-based grease to the thread of the
clutch body and screw down onto the brake lining. (Ensure all
components are lined up and the clutch body does not pinch any of
the brake linings)

Secure the rope using the plate ensuring the end stop is seated inside
the groove of the rope drum and does not protrude into the path of the
rope.
11. WIND THE ROPE ONTO THE DRUM
Using a 17 mm socket and drill adapter, wind the drum via the nut
in the clutch body. Keep the pawl stop in free spool position to prevent
excessive wear on the tip and neatly lay the rope until fully wound.
Retain the rope in position by clipping the safety hook to the stay bolt.
