Dingtai manufactures complete Yanmar track groups, including track chains, links, pins, bushings, bolts, and shoes. These assemblies support and drive compact excavators.
We provide factory-direct supply with full OEM manufacturing services for global equipment distributors and fleet owners. No trading agents, direct pricing.
This track group resists wear, elongation, and breakage under high-load conditions. It minimizes unplanned downtime and reduces cost per operating hour.
With over 20 years of engineering experience, Dingtai holds ISO9001 and SGS certifications. Our quality system ensures consistent metallurgical and dimensional control.
We use 35MnB material, precision machining, and deep hardening on pins and bushings. This delivers extended service life in abrasive environments.
Core Selling Points
- Global Brand Compatibility: Track groups are engineered for Yanmar models including VIO, B, SV, and other series. Dimensional interchangeability is verified before shipment.
- Premium 35MnB Material: Track links are forged from 35MnB steel for high tensile strength and impact resistance. This reduces cracking under severe digging loads.
- Deep Quenching/Heat Treatment: Pins and bushings receive induction hardening to HRC 50–60. Deep case depth improves wear resistance and extends track life.
- 100% QC Inspection: Every assembly undergoes dimensional checks, hardness testing, and torque verification. This guarantees reliable fitment and reduces warranty claims.
Our catalog of Yanmar Track Group includes various specifications, fully compatible with Yanmar excavators and compact track loaders.

Technical Features
Sealed track groups use floating seals and bimetal bushings to retain oil and exclude dirt. This reduces internal pin-and-bushing wear.
Heat treatment creates a hard wear surface while maintaining a tough core. This prevents surface cracking and extends link pitch life.
Shoe bolts use high-tensile fasteners and uniform grouser contact. Proper torque retention reduces loosening under vibration in abrasive jobsites.
Applications
- Road construction and site development
- Quarrying and aggregate processing
- Underground mining and tunneling support
- Demolition and recycling yards
- Utility trenching and pipeline contracting
- Municipal snow and landscape operations
Frequently Asked Questions
What is the minimum order quantity for Yanmar track groups?
MOQ is one complete set per model. Sample orders for a single track group are accepted for first-time buyers.
What is the delivery time?
Standard production takes 15–30 days depending on order size and specification. Custom OEM orders may require additional tooling time.
How deep is the heat treatment on pins and bushings?
Induction hardening typically reaches a case depth of 4–8 mm, with surface hardness HRC 50–60 depending on part number.
What warranty is included?
We provide a 12-month or 2,000-hour warranty against material and manufacturing defects. Warranty does not cover normal wear or misuse.
Can you match part numbers from Yanmar or other suppliers?
Yes. Send your OEM part number or track shoe width and pitch. We verify interchangeability before production.
Do you supply rubber tracks or steel track groups?
This page covers steel track groups. We also offer replacement rubber tracks and undercarriage parts upon request.
What information is required for a quote?
Provide machine model, serial number breakdown, number of links, shoe width, and pitch. Photos of existing links help ensure exact fit.
Do you provide installation support?
We supply installation instructions and technical drawings. Direct video support is available for complex assembly questions.
Maintenance Guide
- Clean track frame and inspect sprocket, idler, and rollers before installation. Worn components accelerate new track group wear.
- Align link pin with sprocket teeth and ensure shoe bolts are torqued to OEM specifications after initial 50 hours.
- Check track sag daily. Excessive sag causes derailment, while over-tensioning increases pin and bushing load.
- Inspect for cracks, missing shoe bolts, or uneven grouser wear every 250 hours. Replace damaged shoes immediately.
- Plan replacement when bushing wear exceeds 15% of original diameter or link pitch elongation exceeds 3%.
