A search for XS85 bucket teeth can lead to several teeth with different shapes and part numbers. They belong to the same numbered series, but “XS85” alone does not identify the tooth a buyer needs. The complete reference, the adapter on the bucket and the retaining arrangement all matter when checking a replacement.
This guide compares six published XS85 tooth references and explains what to verify before ordering. It is intended for distributors, importers, contractors and maintenance teams sourcing replacement ground engaging tools.
Published XS series specifications list these as separate tooth references:
Part reference | Tooth style | What to confirm |
XS85SYL | Standard | Check that the existing tooth uses the standard profile. |
XS85RC | Rock chisel | Compare the chisel profile and the existing part reference. |
XS85T | Tiger | Confirm that a single-point tiger tooth is required. |
XS85WT | Twin tiger | Check the twin-point profile and complete reference. |
XS85RP2 | Rock penetrator | Confirm the RP2 suffix on the specified part. |
XS85RP3 | Rock penetrator | Confirm the RP3 suffix; do not substitute RP2 by appearance. |
The suffix distinguishes one style from another. Keep it on the RFQ and purchase order, even when photographs make two teeth look similar.
The worksite also affects profile selection. A standard tooth may suit a general application, while a pointed or chisel profile may be considered where penetration is a priority. Rock penetrator styles are separate options. The right choice still depends on the installed tooth system, the material being handled and the equipment operator’s experience.
Start with the number on the tooth being replaced. Photograph the marking before the part is removed if it remains legible. Record every letter and suffix, then compare it with purchase records and bucket documentation.
Some records use an older number or a different brand reference. Treat that number as a lead for investigation. A catalogue cross-reference does not establish that a particular aftermarket tooth will fit the adapter currently on the machine.
This distinction matters for XS85RC replacement inquiries. Parts listings may associate rock chisel teeth with several Komatsu or KMAX references. Provide the number shown on your existing part or record, but ask the supplier to identify the exact replacement being offered. The proposed tooth, adapter interface and retaining parts should be checked together before an equivalence claim is accepted.
A bucket tooth works as part of an assembly at the bucket cutting edge. Its inner pocket must seat on the installed adapter, and the intended pin or other retainer must match the locking arrangement. Two teeth can have similar outer profiles yet differ at the mounting interface.
1. Identify the complete tooth reference. Specify SYL, RC, T, WT, RP2 or RP3.
2. Check the installed adapter. Record its number if visible and photograph the adapter nose.
3. Check the retaining arrangement. Photograph the locking position and note any pin reference.
4. Compare relevant dimensions. Use the proposed supplier drawing and measurements from the actual assembly where identification remains uncertain.
5. Inspect the adapter’s condition. Wear or damage can affect how a replacement tooth seats and locks.
6. Confirm what the quotation includes. A tooth, pin and other retaining parts should be listed separately when applicable.
If a marking is missing or two sources give different specifications, request additional photographs or measurements. Do not resolve the difference from the tooth’s outside shape alone.
Send the machine manufacturer, model and serial number when available. These details help a supplier search parts information and understand the application. Bucket or attachment identification is equally useful.
A machine may carry a replacement bucket or an adapter system different from the one originally supplied. For that reason, a machine model mentioned in an online product title cannot confirm every tooth installed on that model. Check the bucket and adapter actually in service.
When the old tooth has no readable number, provide clear photographs of the whole bucket, one tooth from the front and side, the tooth pocket, the exposed adapter nose and the retaining position. Include a measurement photograph where needed. Measure from sound, identifiable surfaces rather than relying only on severely worn edges.
Replacing a tooth is an opportunity to check the parts that will remain on the bucket. Look for distortion or heavy wear on the adapter nose, damage around the locking area, cracks and uneven wear across tooth positions.
These observations help guide an inspection; they are not universal replacement limits. Follow the equipment owner’s maintenance procedure and obtain technical advice for a damaged assembly. If the adapter is excessively worn, ordering a new tooth without addressing the adapter may leave the fitment issue unresolved.
Tell your supplier about the working material and the positions that wear fastest. General excavation, rock handling and abrasive conditions can create different purchasing needs. This information supports a useful profile discussion without assuming that one XS85 style suits every site.
A complete inquiry helps the supplier identify the proposed variant and quote the correct contents. Include:
l Tooth identification: the complete part number, all readable markings and any older reference in your records.
l Required styles and quantities: separate line items for SYL, RC, T, WT, RP2 and RP3 if ordering more than one style.
l Machine and bucket details: manufacturer, model, serial number if available, and attachment information.
l Adapter and pin details: visible references and photographs of the nose and locking area.
l Comparison material: existing tooth photographs, relevant measurements and an approved drawing if available.
l Application: working material, site conditions and any unusual wear pattern.
l Order requirements: whether pins are needed, packaging requirements and delivery destination.
For a fleet order, group this information by bucket configuration. That makes it easier to identify machines fitted with different adapters or tooth styles, even when they share a machine model.
YASSIAN is a China-based factory supplier of bucket teeth, adapters and other ground engaging tools. If you are sourcing an XS85-style replacement, explore our bucket teeth range and send us your full tooth reference, adapter and pin photographs, quantity and destination. We can review the information, check which relevant products are available and provide the specifications and quotation details for the proposed item.If the existing part number is missing, send photographs of the tooth and installed assembly so the identification can begin from the parts you have.
