Track Tensioner 156-40-02000-01 | Track Adjuster Assembly for Shantui DH24 Bulldozer

This 156-40-02000-01 track tensioner assembly is a standard OEM replacement part specially engineered for Shantui DH24 series bulldozers. As a core component of bulldozer undercarriage system, it works steadily to keep crawler tracks at the ideal tightness during all working conditions.

Improper track tension will easily lead to track derailment, abnormal wear of track links and rollers, and even affect the overall running stability of the machine. This tensioner absorbs impact force from rough construction sites effectively, protects the whole undercarriage structure, and greatly extends the service life of related parts.

Basic Product Information

Basic Parameters

• Part Number: 156-40-02000-01

• Common Name: Track Tensioner / Track Adjuster / Recoil Spring Assembly

• Applicable Model: Shantui DH24 Bulldozer (DH24-B3, DH24-G, DH24-M full series)

• Application Position: Undercarriage, front idler track tension system

• Assembly Type: Integrated hydraulic & spring combination assembly

• Original Standard: OEM standard, direct replacement without modification

Main Material & Craft

We adopt high-strength alloy steel as the main raw material for the tensioner body and recoil spring. All metal parts go through overall forging, quenching and surface anti-rust treatment. The internal sealing components use wear-resistant rubber material, which resists oil leakage, mud and sand erosion, and adapts to harsh working environments such as mines, earthwork sites and road construction.

Compared with ordinary spare parts, our tensioner has stronger compression resistance and fatigue resistance, and can maintain stable performance under long-time high-load operation.

Core Structure & Working Principle

Main Components

The complete 156-40-02000-01 tensioner assembly includes hydraulic adjust cylinder, recoil tension spring, sealing set, grease nozzle, connecting pin and protective housing. Every matching part is strictly calibrated according to original size to ensure seamless assembly.

Working Mode

This assembly adopts grease injection adjustment design. Users can fill grease through the reserved grease port to push the hydraulic cylinder outward, so as to tighten the crawler track. When it is necessary to loosen the track, release a small amount of grease properly to retract the cylinder. The built-in high-elastic spring plays a buffering role all the time, which can automatically buffer the vibration and impact generated when the bulldozer travels.

Product Advantages

1. Perfect Fit: Strictly produced according to OEM drawing size, plug and play, no cutting or welding required during installation, save maintenance time on site.

2. Excellent Durability: High hardness spring and wear-resistant seals reduce daily failure rate, lower your later replacement and maintenance cost.

3. Stable Tension Control: Precise hydraulic structure ensures consistent track tension, avoids frequent track adjustment.

4. Wide Adaptability: Compatible with all versions of Shantui DH24 bulldozers, suitable for engineering machinery rental fleet, repair shop and construction team use.

Installation & Maintenance Tips

• Before installation, clean the mounting position and matching surface to prevent gravel from causing poor assembly.

• Adjust track tension moderately. Too tight or too loose will accelerate part wear.

• Check the sealing condition and grease volume regularly. Refill grease in time according to working hours.

• If oil leakage or spring fatigue occurs, please replace the whole assembly immediately to avoid secondary damage to the track system.
