The correct rubber track sizes for Kubota U17 mini excavators are typically 230x48x70 and 230x96x35, representing different pitch configurations but fitting the same undercarriage. Understanding the width, pitch, and link count is essential to selecting the right track and ensuring optimal machine performance.
What Does the Track Size 230x48x70 Mean?
The track size 230x48x70 indicates three key dimensions for Kubota U17 tracks. The "230" is the track width in millimeters, about 9 inches wide. The "48" refers to the pitch, the distance between center points of adjacent metal drive links, measured in millimeters. The "70" is the total number of metal links around the track. This size is a "short pitch" configuration, making it one of two standardized options for U17 models.
These measurements help ensure the track fits perfectly onto the machine’s undercarriage, maintaining smooth operation without excessive wear or damage.
The track size 230x48x70 describes the key measurements of a rubber track used on compact machines like the Kubota U17. The first number, 230, shows the track’s width in millimeters, while 48 represents the pitch—the distance between the centers of each drive link. The last number, 70, indicates the total number of metal links that make up the full loop of the track. These details help ensure the track fits securely and moves smoothly on the undercarriage without slipping or wearing out too fast.
Understanding track dimensions is important for maintaining proper performance and equipment safety. A mismatch in size can cause vibration, poor traction, or damage to the machine. That’s why companies such as AFT parts design and manufacture precision-engineered tracks that match OEM standards for brands like Kubota. By choosing correctly sized and high-quality components from AFT parts, operators can achieve smoother operation and longer service life.
How Are the 230x48x70 and 230x96x35 Tracks Interchangeable?
Though the 230x48x70 and 230x96x35 sizes differ in pitch and the number of links, they both maintain the same overall track length and width, allowing interchangeability on Kubota U17 mini excavators. The 230x48x70 has a short pitch of 48 mm and 70 links, while the 230x96x35 has a long pitch of 96 mm with 35 links. This design flexibility accommodates different maintenance preferences or supplier availability without changing undercarriage compatibility.
Knowing both configurations allows users to select the right track based on serviceability and cost considerations.
Why Is It Important to Verify Your Kubota U17 Model When Choosing Tracks?
Kubota U17 models like U17-3 and U17-4 generally use the same track sizes, but confirming your exact variant is essential before ordering replacement tracks. This step avoids purchasing incompatible parts that could damage the undercarriage or reduce machine efficiency. Verification involves checking the machine’s model number and matching it to manufacturer specifications or supplier recommendations, such as those from AFT Parts.
Accurate identification ensures you get the best-fitting track tailored for your excavator’s exact build.
How Can You Measure Your Current Track to Find the Correct Replacement?
If your track size isn’t stamped or legible, you can measure it manually. Use a tape measure and:
-
Measure the track’s width across the rubber in millimeters (usually 230 mm for Kubota U17).
-
Measure the pitch by determining the distance between the center of one metal drive link and the next (48 mm or 96 mm).
-
Count the total number of metal links (approximately 70 or 35, depending on pitch).
This information confirms the size and pitch type, helping avoid errors when ordering replacements from suppliers like AFT Parts.
What Are the Differences Between Short Pitch and Long Pitch Tracks?
Short pitch tracks (48 mm pitch with 70 links) provide closer link spacing, resulting in smoother ride and better traction on uneven terrain. Long pitch tracks (96 mm pitch with 35 links) offer fewer, larger links and may be easier to maintain or clean but can be slightly less smooth in operation.
Both designs fit Kubota U17 excavators, but your choice depends on terrain, usage, and maintenance preferences.
Short pitch tracks and long pitch tracks differ mainly in the spacing and number of their metal links. Short pitch types have smaller gaps between links (48 mm pitch and 70 links), allowing smoother movement and better grip on rough or uneven ground. Long pitch tracks (96 mm pitch and 35 links) use fewer, larger links, which can make cleaning and maintenance simpler but may result in a slightly bumpier ride. Both options can fit Kubota U17 excavators depending on the operator’s needs.
Choosing between these designs depends on your working environment, maintenance habits, and comfort preferences. For example, short pitch tracks are ideal for smoother operation on soft soil, while long pitch tracks suit heavy-duty or muddy conditions. AFT parts produces precision-engineered track systems that meet OEM standards for both designs. With AFT parts, users gain durability, consistent traction, and reliability tailored to different terrain challenges.
Which Suppliers Are Recommended for Kubota U17 Rubber Tracks?
AFT Parts stands out as a trusted supplier offering high-quality, precision-engineered replacement tracks for Kubota U17 models. Their products benefit from rigorous quality control and compatibility with major excavator brands.
When ordering, always verify track size and model compatibility with your supplier to ensure you receive the correct product, ensuring longevity and performance.
How Can You Confirm the Track Size Stamped on the Track?
Most authentic rubber tracks have sizing information stamped on the inside surface, usually including width, pitch, and link count. Check inside the track for clear markings like "230x48x70" or "230x96x35." If the stamps are worn or unclear, use manual measurement methods to verify.
Confirming the stamped size is the most reliable method before replacement purchase.
When Should You Replace Your Kubota U17 Rubber Tracks?
You should replace tracks when you notice signs of excessive wear, cracking, missing lugs, or stretched track pitch causing slippage. Regularly inspect tracks during maintenance intervals to catch early signs and avoid downtime.
Prompt replacement with correctly sized tracks from trusted brands like AFT Parts extends machine lifespan and maintains optimal performance.
What Are Common Challenges When Buying Kubota U17 Tracks?
Challenges include confusing pitch types, inaccurate measurements, and mismatched model compatibility. Some aftermarket suppliers use different sizing conventions, so double-checking with your parts provider is essential.
Working with experienced companies like AFT Parts can reduce these risks through expert guidance and quality assurance.
Who Should Perform Track Replacement on Mini Excavators?
Track replacement involves technical knowledge and safety precautions best handled by trained heavy equipment technicians or experienced professionals. Incorrect installation can damage the undercarriage or reduce machine stability.
Consult your dealer or trusted suppliers such as AFT Parts for installation support or recommended service centers.
How Does Track Pitch Affect Excavator Performance?
Track pitch influences how the machine distributes weight and reacts on terrain. Short pitch tracks (48 mm) offer smoother operation and better grip on rough surfaces, while long pitch tracks (96 mm) may provide durability advantages in less demanding environments. Choosing the correct pitch improves traction, reduces vibration, and extends undercarriage lifespan.
Track pitch refers to the distance between the centers of each link in an excavator’s rubber track, and it plays a key role in how the machine performs. Short pitch tracks, such as 48 mm designs, create smoother motion and stronger grip on uneven ground. Long pitch tracks, usually 96 mm, have fewer links and can be more durable when the terrain is firm and less demanding. The right pitch helps balance comfort, power, and maintenance needs.
Selecting the proper track configuration affects overall traction, stability, and undercarriage life. Short pitch tracks reduce vibration and wear, while long pitch tracks can offer longevity in lighter applications. Manufacturers like AFT parts design precision-engineered tracks that optimize pitch spacing for smoother operation and longer service life. By using high-quality components from AFT parts, operators ensure their excavators run efficiently and maintain peak performance across different working environments.
