Dingtai manufactures track adjust assemblies, the grease tensioning cylinders that maintain correct track tension in undercarriage systems.
We offer factory-direct supply and complete OEM manufacturing services for global distributors, dealers, and equipment fleets requiring exact-fit replacement parts.
Proper track adjustment prevents premature pin and bushing wear, reduces derailment risk, and minimizes downtime in demanding earthmoving applications.
With over 20 years of experience, Dingtai holds ISO9001 and SGS certifications, ensuring consistent quality and traceability for every assembly.
Each assembly uses high-strength steel, precision-machined cylinders, and deep quenching heat treatment to withstand extreme tension loads and harsh site conditions.
Core Selling Points
- 20+ Years Experience: Dingtai has manufactured undercarriage components for over two decades, supplying mining and construction clients with proven quality and technical support.
- Global Brand Compatibility: Our Liebherr track adjust assemblies are direct replacements, matching OEM mounting dimensions and hydraulic port configurations for multiple excavator models.

Technical Features
The assembly uses a grease-filled cylinder and piston. Pumping grease extends the idler, tightening track sag and preventing detracking.
Internal floating seals retain grease while blocking dirt, water, and abrasive slurry. The chrome-plated rod resists scoring and corrosion for consistent tension.
A heavy-duty recoil spring absorbs shock loads from rocks or hard impacts, protecting the final drive and undercarriage frame from stress damage.
Applications
- Mining and quarry operations
- Road construction and earthmoving
- Demolition and recycling
- Forestry and heavy material handling
- Infrastructure development
Frequently Asked Questions
1. What is the minimum order quantity for Liebherr track adjust assemblies?
MOQ is one unit for replacement orders. Bulk orders receive tiered pricing.
2. How long is delivery?
Production takes 15–25 days. Stock assemblies ship within 7 days, plus transit time to destination.
3. Do you match Liebherr OEM part numbers?
Yes, provide the OEM part number or drawing. We confirm interchangeability before production.
4. What kind of heat treatment is applied?
Cylinder wear surfaces are induction hardened to HRC 45–52. Rods receive chrome plating for abrasion resistance.
5. What warranty comes with the assembly?
12 months or 2,000 operating hours against manufacturing defects, whichever occurs first under normal use.
6. Can you manufacture custom stroke lengths?
Yes, we customize stroke length, mounting dimensions, and seal specifications according to customer drawings.
7. How do I know if the track adjuster needs replacement?
Check for grease leaks, inability to hold tension, scored rods, or cracked cylinder bodies.
Maintenance Guide
- Inspect: Check for grease leaks, rod scoring, and cylinder cracks every 250 operating hours, especially in abrasive mining environments.
- Grease tension: Use recommended lithium-based grease. Pump until track sag matches OEM specification; do not over-tension.
- Installation: Clean mounting bores, align the yoke, and torque bolts to OEM specifications to prevent premature wear.
- Replacement interval: Replace at first sign of internal seal failure or physical damage; do not operate with collapsed tension.
