Dingtai manufactures Daewoo U-Yokes for track tensioning assemblies. Each yoke transfers force between the hydraulic adjuster cylinder and front idler.
We are a factory-direct China manufacturer providing full OEM services. Global distributors receive consistent quality with Daewoo-compatible dimensions and part numbers.
Forged alloy construction resists bending and cracking under high track loads. This reduces downtime and extends undercarriage service life.
Dingtai brings 20-plus years of undercarriage manufacturing experience. ISO9001 and SGS certified processes ensure every Daewoo U-Yoke meets strict quality standards.
We use 35MnB alloy steel with deep quenching. This creates a hardened wear surface and a tough core for impact resistance.
Core Selling Points
- Premium 35MnB Material: High-strength 35MnB alloy steel provides superior tensile strength and resistance to bending under extreme excavator working conditions and shock loads.
- Precision Forging/Casting: Precision-forged blanks with CNC machining deliver accurate yoke dimensions and reliable fit against the Daewoo idler assembly without field modification.
- Deep Quenching/Heat Treatment: Heat treatment hardens contact surfaces to 48–55 HRC while maintaining a ductile core for prolonged service life in abrasive conditions.
- 100% QC Inspection: Every U-Yoke receives dimensional inspection, hardness testing, and visual checks before packaging, ensuring zero-defect shipment to global clients.
Product Range
Our catalog of Daewoo U-Yoke includes various specifications, fully compatible with Daewoo excavators and bulldozers.

Technical Features
The U-Yoke is forged from 35MnB steel, eliminating internal voids. This structure handles alternating loads from track recoil and tensioning.
Deep quenching produces a hardened contact face while retaining a tough core. This resists wear at idler and adjuster interfaces.
CNC machining ensures concentric pin bores and accurate yoke width. Proper alignment reduces side loading and bushing wear in Daewoo undercarriages.
Applications
- Mining: Continuous track adjustment under abrasive rock and high-impact digging.
- Road Construction: Long hours on graded surfaces with frequent forward/reverse travel.
- Quarrying: Heavy side loads and shock from loading blasted material.
- Demolition: High vibration and debris impact in unstable ground conditions.
- Forestry: Rough terrain operation with constant tensioner cycling.
Frequently Asked Questions
1. What is the MOQ for Daewoo U-Yoke?
Standard MOQ is 10 pieces per part number. Mixed Daewoo U-Yoke models can be combined in one container for trial orders.
2. What is the delivery time?
Stocked sizes ship within 7–15 days. Custom production typically requires 25–35 days after drawing confirmation.
3. How deep is the heat treatment?
Contact surfaces are hardened to 48–55 HRC with an effective case depth of 3–6 mm depending on wall thickness.
4. What warranty do you provide?
We provide a 12-month or 2,000-operating-hour warranty against material and manufacturing defects under normal use.
5. Can you match my original part number?
Yes. Provide the original Daewoo or Doosan part number or drawing, and our engineers verify dimensions before production.
6. Do you offer samples?
Yes. Sample orders are available. Freight is charged on samples, but sample cost is refundable on bulk orders.
Maintenance Guide
- Inspect U-Yoke during regular undercarriage service. Check for cracks, elongation at pin bores, and uneven wear on contact faces.
- Verify track tension adjustment before operation. Over-tensioning increases yoke and idler load, accelerating fatigue failure.
- Replace worn pins and bushings together with the U-Yoke. Mixed new and worn components cause misalignment and rapid wear.
- Grease pin bores per the machine schedule. Contaminated or dry joints increase friction and side loading.
- Replace U-Yokes showing cracks or measured deformation. Do not weld repair high-stress forged components.
