Dingtai manufactures Yanmar track guards as direct replacement undercarriage protection that shields final drives, track frames, and idler assemblies from impact damage.
Factory-direct production with OEM manufacturing services supports global buyers requiring custom dimensions, brand-compatible fit, and consistent batch-to-batch quality control.
This guard prevents premature undercarriage wear and unscheduled downtime by absorbing debris impact and reducing stress on track chains and drive components.
With over 20 years of engineering experience and ISO9001/SGS certified processes, Dingtai delivers verified durability and dimensional accuracy for demanding field conditions.
We use 35MnB alloy steel with deep induction quenching to achieve high surface hardness, improving impact resistance and extending track system service life.
Core Selling Points
- Premium 35MnB Material: Track guards are formed from 35MnB alloy steel, offering high tensile strength and excellent fatigue resistance under repeated impact loads.
- Deep Quenching/Heat Treatment: Induction hardening and tempering produce a hardened wear surface that resists gouging while the core remains tough to prevent cracking.
- Global Brand Compatibility: Manufactured to match Yanmar undercarriage mounting points, ensuring direct installation without field modification across common ViO and SV series.
- ISO9001/SGS Certified: Production and inspection follow ISO9001 standards with SGS material verification, delivering consistent quality for replacement and OEM supply programs.
Our catalog of Yanmar Track Guard includes various specifications, fully compatible with Yanmar excavators and tracked carriers.

Technical Features
Each track guard uses a bolt-on design shielding the final drive and track frame from rock ingestion and side impact.
Surface induction hardening creates a 4–6 mm wear-resistant layer while the core remains tough, preventing brittle fracture under severe loading.
Precision-cut mounting holes align with Yanmar factory lugs, reducing installation time and maintaining proper track sag adjustment.
Applications
- Utility construction and trenching
- Road repair and curbing
- Landscaping and site development
- Demolition and material handling
Frequently Asked Questions
What is the minimum order quantity for Yanmar track guards?
MOQ is 5 units for standard specifications; custom OEM orders may require 20 units depending on drawing revisions.
What is the delivery time?
Standard items ship within 7–15 days. Custom production requires 25–35 days depending on order quantity and heat treatment capacity.
How deep is the heat treatment?
Surface hardening depth is 4–6 mm, with surface hardness of 48–55 HRC and a tough core.
What warranty is provided?
We provide a 12-month or 1,500-hour warranty against material and manufacturing defects under normal operating conditions.
Can Dingtai match our Yanmar part numbers?
Yes. Provide OEM part numbers or drawings; our engineering team verifies dimensions and confirms exact replacement compatibility.
Are these guards suitable for mining or demolition?
Yes. The hardened 35MnB steel construction is designed for high-impact environments including demolition, quarry, and utility work.
Do track guards require special tools for installation?
No. Bolt-on design uses standard hand tools and existing Yanmar mounting points.
Maintenance Guide
- Verify all mounting points are clean and free of debris. Torque bolts to Yanmar specification after positioning the guard.
- Inspect guards every 250 hours for cracks, loose bolts, or deformation caused by heavy impact.
- Replace if wear exceeds 30% of original thickness or if mounting holes elongate and prevent secure fitment.
- In high-impact applications, replace track guards at 1,500–2,000 hours or when structural integrity is compromised.
