Why the 2713 Series Became the Doosan Bucket Teeth Default

The 2713 designation is the OEM catalogue code that Doosan inherited from the original Daewoo heavy equipment line and has kept consistent across three product generations. When we talk about the 2713 series at Join Machinery, we mean the family of teeth and adapters that physically fit every Doosan excavator from the 22-ton DH220 up to the 50-ton DH500, using one of three adapter profiles. This is a bigger statement than most replacement buyers realize, because competing after-market lines typically require three to five different tooth-and-adapter families to cover the same range.

The 2713 family consolidates because the tooth nose geometry is identical across all models. What changes between DH220 and DH500 is the adapter — the weld-on piece that bolts (or welds) to the bucket lip and locks the tooth in place. Three adapter profiles cover seven excavator models because the load class shifts at three breakpoints: 22–28 ton, 30–42 ton, and 42–50 ton.

This consolidation matters for two practical reasons. First, distributors can hold inventory in fewer SKUs and still cover the entire Doosan population in a typical rental fleet. Second, field mechanics can swap teeth across machines without re-engineering the bucket lip. Both reasons drive the 2713 line’s dominance in after-market replacement sales, which is why the Join Machinery Doosan product range carries the 2713 designation as the primary tooth series.

Upgrade note: This article is the chart-version upgrade of our earlier selection guide Doosan DH220–DH280 Replacement Bucket Teeth Selection Guide. The earlier guide focused on adapter matching rules for the smaller DH220–DH280 pair; this version expands the table to the full DH220–DH500 range and adds reverse-adapter identification, installation geometry, and the lead-time / MOQ reference for OEM buyers.

Quick Reference: Doosan 2713 Compatibility Chart

This is the chart-version compatibility table buyers have been asking for. It consolidates the seven Doosan excavator models in the 2713 coverage range with the matching tooth, adapter, and section profile.

Three observations from the table. First, the 2713-1217 tooth fits both the DH220 and DH280 because the tooth nose is identical between these two models — only the adapter is shared (2713-0001), and the bucket lip weld spacing is the same. Second, the DH420 is a transition model where either the 2713-0028 or the 2713-0035 adapter may be specified depending on the bucket’s intended duty cycle. Third, the DH500 uses the 2713-0035 exclusively because the extra-heavy adapter section profile is needed for the 50-ton load class.

The 2713-1217 DH220 standard bucket tooth is the highest-volume SKU in the 2713 line because DH220-class machines are the most common rental-fleet population and the 2713-1217 also fits the DH280 with the same adapter.

Bucket Tooth Series Code: Decoding 2713-1217 vs 2713-9W8451

The 2713 designation prefix is Doosan’s catalogue code for the tooth-and-adapter family. The four-digit suffix after the hyphen is a model-specific tooth reference. Here is how to decode the two most common references in the 2713 line.

2713-1217 (DH220 / DH220LC-7 / DH280 standard tooth)

The 2713-1217 is the standard-profile bucket tooth designed for the DH220 and DH220LC-7 excavators. The 1217 suffix is Doosan’s part reference for the tooth profile and length. It is the highest-volume SKU in the 2713 family because the DH220 is the most common Doosan excavator in rental fleets worldwide. Buyers specifying the 2713-1217 should pair it with the 2713-0001 adapter for both the DH220 and DH280 fitments.

2713-9W8451 (DH300 / DH330 / DH360 / DH420 / DH500 heavy tooth)

The 2713-9W8451 is the heavy-profile tooth designed for the DH300 through DH500 range. The 9W8451 suffix indicates a longer tooth with a heavier section profile suitable for quarry and mining duty cycles. Buyers specifying the 2713-9W8451 should pair it with the 2713-0028 adapter for DH300 through DH420, and the 2713-0035 adapter for DH420LC-9S through DH500.

Field tip: a buyer who orders a 2713-9W8451 tooth without specifying the adapter can end up with a tooth that physically does not lock into their existing bucket lip. Always specify the adapter family (2713-0001 / 2713-0028 / 2713-0035) alongside the tooth reference.

Adapter Matching Rules: 2713-0001 / 2713-0028 / 2713-0035

The adapter is the weld-on (or bolt-on) piece that holds the tooth on the bucket lip. Three adapter profiles cover the entire 2713 series because the load class shifts at three breakpoints.

Three rules govern correct adapter matching. First, the adapter weld spacing must match the existing bucket lip weld pattern. If the bucket was originally manufactured for the 2713-0001 standard profile, switching to the 2713-0028 requires re-welding the lip. Second, the adapter section profile must match the load class — installing a 2713-0001 on a DH500 bucket will result in adapter shearing under the 50-ton load class. Third, the tooth nose geometry must match the adapter locking profile — all 2713-series teeth share the same nose geometry, which is what allows one tooth design to span seven models.

Adapter Profile Selection by Fleet Composition

Buyers specifying adapters for a fleet with mixed Doosan models typically stock all three profiles. Buyers with a single-model fleet (e.g. a rental yard with only DH360s) stock only the 2713-0028 profile and order the matching 2713-9W8451 tooth.

Adapter Weld Repair vs. Full Replacement

When an adapter fails in field service, the repair-versus-replace decision depends on the crack location and the parent bucket material. Surface cracks on the adapter nose are weld-repairable using a low-hydrogen electrode with 150°C pre-heat. Cracks that propagate into the bucket lip parent material require full adapter replacement plus weld build-up on the lip.

Storage and Staging for Multi-Model Distributors

Distributors holding inventory across the 2713 adapter family typically stage by profile code rather than by excavator model. This means the 2713-0001 / 2713-0028 / 2713-0035 are stored in three bins regardless of which Doosan model they fit. The tooth SKUs (2713-1217 / 2713-9W8451) are stored in two additional bins. Total SKU count for full-range 2713 coverage is five.

Weight & Material Compatibility by Model Class

Material grade is where most after-market tooth suppliers cut corners. The Doosan OEM 2713 series specifies an alloy steel with through-hardened nose, where the wear surface reaches 48–52 HRC while the core remains at 32–36 HRC for impact resistance. This is not a marketing claim — it is the material specification that the 2713 design assumes for proper tooth life.

Industry cross-check: Hardness ranges and material grades above align with the Penticton Foundry abrasion-resistant cast iron reference and the ASTM A532 Class I Type A Ni-Hard 1 reference. The white-iron carbide structure described there is what gives the 2713 nose its abrasive-wear life in quarry and mining service. Join Machinery operates as an OEM-equivalent partner to BYG wear parts and JCB ground engaging tools for European and American distribution of the 2713 series and equivalent tooth-and-adapter families.

The hardness split (hard nose, tough core) is critical. A tooth that is uniformly hard across the section will chip at the nose-to-shank transition under impact loading. A tooth that is uniformly soft will wear through in 200 to 400 hours in abrasive soil. The Doosan OEM spec calls for the 48–52 / 32–36 HRC split because it is the combination that survives both wear and impact in the same tooth.

When to Use 2713-1217 vs Reverse-Adapters

Reverse-adapter situations arise when a buyer wants to fit a 2713 tooth to a bucket that was originally manufactured for a different tooth family — typically an older Doosan bucket designed for the 230-series teeth, or a third-party bucket with a non-standard weld pattern. In these cases, a reverse-adapter is welded to the bucket lip and provides the 2713 locking profile.

Three reverse-adapter scenarios are common in field service:

1. 230-series to 2713-series upgrade. Older Doosan buckets built before the 2713 designation was standardized sometimes carry the 230-series weld pattern. A reverse-adapter (Join Machinery part code RA-230-2713) is welded to the bucket lip and converts the locking interface to the 2713 family.
2. Third-party bucket to 2713 retrofit. Non-OEM buckets (e.g. aftermarket heavy-duty buckets) often have a generic weld pattern. A custom reverse-adapter can be engineered to fit the 2713 family. Lead time for custom reverse-adapters is typically 4 to 6 weeks for first article.
3. Worn adapter field-replacement. When the original 2713 adapter wears through (typical life 1,200 to 1,800 hours in abrasive service), the replacement is a same-profile 2713 adapter, not a reverse-adapter. The reverse-adapter is only for fitment conversion, not for wear replacement.

Buyers who specify reverse-adapters should be aware that the weld procedure is critical. Pre-heating to 150–200°C and post-weld stress-relief at 600°C are typically required for low-alloy adapter steels to avoid hydrogen cracking. Field welds without pre-heat typically fail within the first 200 hours of service.

Aftermarket vs OEM: What the 2713 Series Offers

The 2713 series exists in three supply tiers: OEM Doosan (factory-fitted on new machines), OEM-equivalent after-market (manufactured to Doosan specs by third parties such as Join Machinery), and value-tier after-market (manufactured to relaxed specs for price-sensitive buyers).

The Join Machinery OEM-equivalent tier matches the OEM Doosan spec on the critical parameters (through-hardened nose 48–52 HRC, alloy steel composition, quench-tempered adapter 32–38 HRC) while landing at roughly 40–55% of the OEM Doosan price. The value-tier after-market typically uses plain carbon steel without the through-hardened nose, which is why service life drops to 250–500 hours.

For rental fleets running 1,200+ hours per year on abrasive soil, the Join Machinery OEM-equivalent tier delivers the same operating life as the OEM Doosan tier at roughly half the tooth cost. For spot-buy or short-term project work, the value-tier after-market is sometimes acceptable if the buyer is willing to replace teeth two to three times as often.

Total Cost of Ownership: 5-Year Fleet Comparison

A 5-year total cost of ownership comparison for a 10-machine rental fleet running 1,200 hours per year in abrasive soil: OEM Doosan at $8.00/tooth average × 4 replacements per tooth = $32,000 per machine × 10 = $320,000. Join Machinery OEM-equivalent at $3.60/tooth average × 4 replacements per machine = $14,400 per machine × 10 = $144,000. Value-tier after-market at $1.80/tooth average × 9 replacements per machine = $16,200 per machine × 10 = $162,000. The OEM-equivalent tier is the lowest 5-year TCO despite the higher per-piece price because the tooth life matches OEM Doosan.

Brand Customization: OEM Packaging and Markings

Join Machinery supplies the 2713 series in three packaging configurations: bulk-bagged (lowest cost, no individual markings), carton-packed with neutral markings, and OEM-customized with the buyer brand marking on each tooth. OEM-customized packaging adds $0.20 to $0.40 per piece but enables the buyer to sell under their own brand without secondary marking operations.

Industry cross-check: The OEM-equivalent material spec aligns with the ISO 6014:1986 earth-moving machinery ground speed and performance testing reference, the BYG wear parts product range, and the JCB ground engaging tools specification.

Installation Geometry: Side Pin vs Vertical Pin

All 2713-series teeth use a cross-pin retention system where a horizontal pin passes through the tooth and the adapter to lock the assembly together. The pin is retained by a rubber or spring-clip cap on the outer end. There are two retention geometries in field service.

The 2713-1217 and 2713-9W8451 are both designed for side-pin retention as the factory default. Vertical-pin retention is sometimes specified for quarry and mining service where the bucket orientation causes side-pin failures from repeated impact. Buyers specifying vertical-pin retention should order the VP-series variant of the tooth (suffix “-VP” added to the part code).

Field tip: when replacing a worn tooth, always inspect the cross-pin for hairline cracks before re-using it. A cracked cross-pin will fail within the first 50 hours of the new tooth’s life, dropping the tooth into the bucket and potentially damaging the adapter.

Lead Time & MOQ for Doosan 2713 Replacements

Lead time and minimum order quantity are the two operational parameters that determine whether the 2713 line is workable for a buyer’s specific replenishment cycle. Here is the current reference as of August 2026, based on Join Machinery’s standard production slots.

Two operational notes. First, stock 2713-1217 is the fastest-moving SKU and the 1,000-piece MOQ applies to first orders. Repeat orders after the first container can typically drop to 500 pieces if the buyer is willing to accept a longer sampling window. Second, adapter MOQ is lower than tooth MOQ (500 pieces vs 1,000 pieces for stock teeth) because adapter production shares the same heat-treatment line across all three profiles and can be scheduled in smaller batches.

For buyers ordering the full tooth-and-adapter system as a paired replacement, the lead times above are governed by the slower component (typically the adapter, at 30–40 working days). Joining the two for a single shipment is standard Join Machinery practice.
