- Position (tilt forward) bucket attachment (4) and, if necessary, loosen bucket tooth (2) from tooth adapter (4a). Make sure that the choker sling and basket are snug and able to support the bucket tooth.
- With tension on lifting device (5) supporting the weight of bucket tooth (2), separate tooth and fabric basket (1) from tooth adapter (4a) .
- Lower fabric basket (1) onto blocks on the ground. Continue to lower lifting device (5) to remove all tension from choker sling (1a), to relax the choke on the tooth.
- Use one of the following two methods to remove worn bucket tooth (2) into fabric basket (1) :
- Get help to carefully slide fabric basket (1) off worn bucket tooth (2), being careful not to damage fabric basket and/or choker sling (1a) .
- Disconnect lifting device (5) from choker sling (1a) and reattach to the now accessible pin retainer hole in worn bucket tooth (2). Use a suitable clevis and/or chain, dealer supplied. Use lifting device to raise the tooth out of the fabric basket.
- After worn bucket tooth (2) is removed, disconnect lifting device (5) and store 149-0173 Choker-Style Fabric Basket in a clean, dry location to prevent weathering and possible damage.
Install Serviceable Bucket Tooth
Note: New replacement bucket teeth have a precast lifting loop for use wit a suitable lifting device during installation. The 149-0173 Choker-Style Fabric Basket is not normally used to install new bucket teeth. For more information on installing new bucket teeth, refer to the appropriate service manuals.
Use the following procedure to install a serviceable bucket tooth without a precast lifting loop.
- Inspect choker-style fabric basket (1) before each use. If damage is found, discontinue use and destroy immediately. Refer to the Section ""Inspection"
" in this manual for inspection guidelines.
Note: For clarity, the illustrations in this manual do not show all eight fabric basket choker loops. Make sure that choker sling (1a) is inserted through all eight loops on fabric basket (1), including the loop it is anchored to.

- With tooth (2) supported on blocks, get help to carefully slide fabric basket (1) around bucket tooth (2). being careful not to damage the fabric basket and/or choker sling (1a) .
- Attach lifting device to retainer pin hole in bucket tooth (2). Use a suitable clevis and/or chain, dealer supplied. Use lifting device (5) to raise the tooth slightly off the ground and slide fabric basket (1) up over the bucket tooth. Tighten choker sling (1a) around the bucket tooth and then carefully lower the bucket tooth and fabric bag onto blocks on the ground. Once secure, disconnect the lifting device from the bucket tooth retainer pin hole.
Note: Make sure to position fabric basket (1) so the retainer hole is exposed to allow retainer pin (3) installation without damaging the fabric basket.

Inspection
Inspect 149-0173 Choker-Style Fabric Basket
 | |
| Illustration 11 | g02849123 |
The 149-0173 Choker-Style Fabric Basket loses strength from normal wear or physical damage due to misuse. Regular inspections help spot early signs of deterioration. If at all in doubt, the fabric basket must be destroyed.
Note: All equipment should be examined by one person only.
- Lay the fabric basket on a flat surface in a well lit area.
- Make sure that the load identification label is securely attached and legible.
- Examine both the exterior and interior of the basket. Inspect basket webbing and loops. Inspect the choker sling and lifting loop. Inspect the inside of the loop for any sign of wear or damage.
- Check for surface chafe, cuts in the webbing or fabric, damaged stitching or seams, and any damage or wear to the lifting loops.
- Check for signs of damage from exposure to harsh chemicals or extreme heat.
- Immediately destroy worn or damaged fabric baskets.
Note: Refer to the Section ""Damage Causes and Results" " in this manual for more information on identifying types of damage and wear.
Damage Causes and Results
The following are typical causes and results of damage to choker-style fabric basket tooling.
Friction Damage - Burning
- Overloading or incorrect positioning will cause friction between webbing and/or fabric and surface being lifting.
- Sliding friction results in heat that melts the surface of the webbing. This type of damage results in the web or fabric surface being hard, brittle, and it will shine, reflect light.
- Inspect by folding the material to see the extent of burning. Stiffness, brittleness, and cracking are signs of burning and melting.
- If damaged, the choker-style fabric basket must always be destroyed.
Friction Damage - Cutting
- Cuts result from friction against unprotected sharp edges of Ground Engaging Tools (GET).
- Cuts may be clean or matted and soft in appearance.
- Cuts may be combined with burning.
- Inspect by folding the material to see the extent of cut damage. Also check for stiffness, brittleness, and signs of burning and melting.
- If damaged, the choker-style fabric basket must always be destroyed.
Friction Damage - Wear
- Wear occurs in localized areas caused by dragging along the ground or against bucket teeth.
- Scuffed surfaces will appear in patches.
- If scuffing is severe and whole threads are broken, the nylon sling or fabric baskets must always be destroyed.
Impact Damage - Load Bearing Threads
- This damage results in load bearing, longitude threads bursting out from the middle or sides.
- If threads are unbroken, there is no loss of strength. However, threads can catch and break if left unattended. Properly repair the sling before using or destroy immediately.
- If threads are broken, there is loss of strength in the webbing, often at a high degree. The choker-style fabric basket must be destroyed.
Lifting Loop or Sling Eye Damage
- Inspect for webbing bursting at the seams.
- Damage is most often caused by using a lifting device hook with a radius smaller than the webbing width.
- If this damage is present, the choker-style fabric basket must be destroyed.
Seam and Stitch Damage
- Inspect for loose or torn stitching at sewn joints and seams.
- If this damage is present, the choker-style fabric basket must be destroyed.
Chemical Damage
- Inspect for damage caused by the effect of harsh chemicals on nylon and fabric slings and baskets.
- This damage is often difficult to identify until in a more advanced stage of deterioration.
- In case of known exposure to harsh chemicals, the choker-style fabric basket must be destroyed.
