Doosan Excavator Track Shoe Assembly Forged 23MnB Steel Triple Grouser 190mm

YT-DX3005-TG700 is a replacement track shoe assembly developed for the Doosan DX300LC-5 crawler excavator, with the DX420LC-5 accepted as a compatible model after size confirmation. The shoe is a triple grouser design arranged on a 190 mm pitch, produced by drop forging 23MnB boron steel. YT manufactures the complete shoe, including machined bolt holes and heat treated tread, so the undercarriage can be restored to working order with simple hand tools and new bolts.

Main Parameters

The models above are just for reference, we can't list all models here. we can supply more products as your requirements. Please feel free to send us your inquiry.

• We purchase the raw materials from famous steel group, ensures the high quality of our track shoes.
• All the track shoes are subject to through hardening processes with spray quenching technique and tempering processes.
• Strict quality control from raw material, design, technology, manufacturing for the entire process of detection.
• We can produce any requested parts according to your blue print or samples.

• Boron steel forging: The 23MnB grade responds well to hardening while retaining toughness, making the shoe dependable on rocky terrain where cast shoes tend to crack.
• Self-cleaning grouser geometry: The triple bar layout lets clay and gravel fall out as the track rotates, which lowers the chance of the track packing solid in wet ground.
• Controlled heat treatment: Quenching and tempering create a uniform structure, followed by induction hardening of the tread that reaches about 48 HRC on the working face.
• Flat link contact area: The underside is machined flat so the shoe sits evenly against the link rails and the bolt torque stays stable during operation.
• Verified dimensions: Pitch, hole diameter and countersink depth are measured with gauges on the production line and recorded for each batch.
• Ready for long transit: A protective oil film and paint layer keep the shoes presentable after weeks of container travel in humid coastal climates.

*Values are reference; OEM part number confirmation advised before ordering.

1. Each incoming coil of 23MnB steel is checked with a spectrometer to confirm carbon, manganese and boron levels.
2. Cut billets are heated evenly and forged on a die press to form the shoe outline with three grousers.
3. Flash is removed by trimming and the blank is punched for the bolt holes in the soft state.
4. Heat treatment normalizes the grain and a quench and temper cycle sets the final mechanical properties.
5. CNC machining finishes the holes, countersinks and the link contact face to drawing tolerance.
6. Induction hardening raises the surface hardness of the grouser tips and flanks.
7. Shot blasting gives a clean surface for inspection and coating.
8. Rockwell hardness testing and magnetic particle inspection are carried out on the batch.
9. Final oiling and pallet packing prepare the parts for export shipment.

Xiamen Yintai Machinery Co., Ltd., founded in 2011, builds undercarriage parts under the YT brand in Fujian, China. The company is a manufacturer and exporter with its own forging workshop, CNC centers and heat treatment plant, meaning track shoes never leave the factory floor for subcontracted processing. The 50-100 person team handles annual export sales of USD 10-20 million, with about 90 percent of output going to overseas markets.

YT holds ISO 9001:2015 certification and regularly accepts SGS or equivalent third-party inspection prior to loading. OEM and ODM work is welcome, from special width shoes to private label cartons and custom marking.

• Hard rock and demolition work: The 700 mm triple grouser shoe keeps traction when the DX300LC-5 breaks concrete or digs through blasted basalt.
• Single source running gear package: Order shoes with matching links, pins and rollers to rebuild the complete track group in one purchase.
• Budget friendly aftermarket route: Dealers can offer their customers a dependable replacement that protects machine availability without the OEM price tag.
• Planned replacement programs: We can schedule production around your fleet service intervals so shoes arrive just before the maintenance window closes.
• Quick turnaround on popular sizes: Standard 700 mm shoes are kept in stock for fast dispatch to ports worldwide.

The DX300LC-5 and DX420LC-5 excavators serve in highway construction, site grading, sewer works and mass excavation. YT triple grouser shoes support these duties with reliable grip on muddy pits and firm footing on paved surfaces, while the 700 mm width suits mixed ground conditions common on infrastructure projects.

Precision Inspection Services

Q1: Which Doosan machines does this shoe match?

The standard build matches the DX300LC-5. The DX420LC-5 and other models in the -5 series may use different chain pitch, so please verify your link pitch and shoe width with our team before ordering.

Q2: Do you use original Doosan part numbers?

No. YT products are aftermarket replacements manufactured to original dimensions. We assign our own part numbers and do not reproduce any OEM brand or part marking.

Q3: How long will a set of shoes last?

Life depends on ground conditions, machine weight and operator habits. On normal earthmoving sites a hardened shoe often outlasts two sets of links; on sharp rock the wear rate is naturally higher.

Q4: Is a trial order possible?

Yes, we accept a single piece or a small test set first. Freight cost for samples is higher per piece, but it gives you confidence before committing to full container volume.

Q5: How are these shoes shipped?

Standard export packing is steel pallets with anti-rust protection, loaded by container. Delivery is 5-7 days from stock and 20-30 days for production orders.

Q6: What after-sales cover is offered?

A 12-18 month warranty against manufacturing defects applies under normal service. Keep the batch number on the carton and send photos if any problem appears.

Finished shoes are oiled, banded on steel pallets and covered to prevent transit damage and corrosion. Every lot carries dimensional records and hardness certificates, and customers may arrange SGS inspection or factory audit at any stage of production.
