The 259D CAT tracks come in two main sizes, 320x86x53 mm and 400x86x53 mm, designed for compatibility with Caterpillar 259D Compact Track Loaders. These tracks offer superior traction, flotation, and durability on varied job sites. Opting for high-quality tracks like those from AFT Parts ensures enhanced machine performance, longer part life, and reduced downtime.
What Are the Exact Track Sizes for the Caterpillar 259D?
The Caterpillar 259D utilizes two primary rubber track sizes:
-
320x86x53 mm (narrow width)
-
400x86x53 mm (wide width)
These measurements represent the track width, pitch (distance between links), and the total number of links, respectively. Both sizes feature 53 links with an 86 mm pitch, accommodating different operating requirements depending on terrain and job demands.
The 320 mm track width is approximately 12.6 inches, while the 400 mm wide tracks provide around 15.7 inches of ground contact width. The longer length of track on the ground, about 59 inches (1499 mm), offers excellent flotation and stability for the 259D's operating weight.
How Does Track Size Impact the Performance of a Caterpillar 259D?
Track size significantly affects machine capabilities:
-
Narrower Tracks (320 mm): Offer increased maneuverability in tight spaces and reduce ground disturbance, making them suitable for landscaping or confined job sites.
-
Wider Tracks (400 mm): Provide better flotation over soft or muddy terrain by distributing machine weight over a larger surface, preventing sinking and improving traction.
-
Pitch and Links: The 86 mm pitch and 53 links ensure smooth power transfer and compatibility with the undercarriage components such as rollers, idlers, and sprockets.
Choosing the appropriate track size allows operators to balance traction, flotation, and machine stability to meet specific operational needs.
What Are the Common Tread Patterns Available for 259D CAT Tracks?
There are multiple tread designs for 259D tracks to optimize performance on different terrains:
| Tread Pattern | Description | Ideal Use Case |
|---|---|---|
| C Block | C-shaped blocks across track width | General construction and hard surfaces |
| Block | Large rectangular blocks | Mixed terrain, balanced traction |
| Zigzag | Angled blocks for multi-directional grip | Muddy and slippery surfaces |
| Multi Bar | Multiple thin bars | Rocky, sandy, and loose soil terrains |
| Straight Bar | Long, straight bars across width | Paved or hard-packed surfaces |
Selecting the right tread pattern based on site conditions enhances grip, reduces wear, and minimizes operator fatigue.
How Do You Maintain 259D CAT Tracks for Longevity?
To extend track life and maintain optimal performance, follow these maintenance tips:
-
Regular Cleaning: Remove mud, rocks, and debris lodged within track links and rollers.
-
Proper Tensioning: Maintain track tension as per Caterpillar’s specifications to prevent slippage or premature wear.
-
Visual Inspection: Frequently check for cracks, cuts, or damaged rubber elements.
-
Lubricate Undercarriage Components: Ensure rollers, idlers, and sprockets are properly lubricated.
-
Prompt Repairs: Replace worn or damaged parts immediately to avoid cascading damage.
Consistent maintenance reduces downtime and repair expenses while improving overall machine safety.

-
Rocky or Abrasive Terrain: Tracks with thicker rubber and aggressive block patterns resist tearing and wear.
-
Hard Surfaces: Smooth or straight bar tracks reduce vibrational wear.
-
Mixed Conditions: Designed versatility like zigzag tread patterns balance grip and wear life.
Understanding jobsite terrain helps optimize track selection for performance and longevity.
What Additional Undercarriage Components Should Be Considered for a Caterpillar 259D?
Beyond tracks, critical components include:
-
Track Rollers: Support and guide the track during machine movement.
-
Carrier Rollers: Maintain track alignment at the top of the undercarriage.
-
Idlers: Help maintain tension and smooth track travel.
-
Sprockets: Transfer power to the tracks by engaging with track links.
Replacing these parts with reliable alternatives such as AFT Parts complements quality track investments and ensures overall undercarriage health.
