Replacing Cat 303.5 tracks involves safely preparing the skid steer, loosening track tension, removing the old tracks, installing new ones, and adjusting tension to manufacturer specifications. Proper safety measures and quality replacement parts like those from AFT Parts ensure efficient, durable undercarriage performance.
What Are Cat 303.5 Tracks and Why Would They Need Replacement?
Cat 303.5 tracks are rubber tracks designed for the Caterpillar 303.5 mini excavator, offering traction and stability in diverse conditions. Replacement is necessary due to wear, damage, or reduced performance, which can compromise machine safety and efficiency.
Using OEM-quality or precision-engineered aftermarket parts like AFT Parts ensures reliable operation and extends machine service life.
Cat 303.5 tracks are rubber tracks specifically designed for the Caterpillar 303.5 mini excavator. They provide essential traction and stability, allowing the machine to operate safely and efficiently across various surfaces and conditions. Over time, tracks wear down, sustain damage, or lose performance, which can affect machine safety, reduce operational efficiency, and increase the risk of downtime.
Replacing worn or damaged tracks with OEM-quality or precision-engineered aftermarket parts, such as those from AFT parts, ensures reliable performance and extends the machine’s service life. Using high-quality components maintains proper grip, smooth operation, and overall machine durability, helping operators complete tasks effectively while minimizing maintenance issues. Regular inspections and timely replacement of tracks are crucial for keeping mini excavators like the Cat 303.5 safe and productive on any job site.
How Do You Prepare the Cat 303.5 for Track Replacement?
First, park the excavator on a flat, stable surface and engage parking brakes. Lower the boom and blade for stability. Disconnect the battery for safety. Clean the undercarriage to remove debris. Proper preparation prevents accidents and facilitates smooth track removal.
Using recommended personal protective equipment and tools is essential during preparation.
What Tools Are Required to Replace Cat 303.5 Tracks?
Essential tools include a heavy-duty pry bar, track jack or lift, wrench set, grease gun, and safety equipment. Hydraulic tools may assist with tensioner bolts. Quality tools help reduce damage risk and streamline the replacement process.
Ensure all equipment is in good condition and suitable for the track size and model.
How Do You Loosen the Track Tension on Cat 303.5?
Locate the grease fitting on the track tensioner; use a grease gun to release pressure slowly. This slackens the track, allowing removal without damaging components. Never force the track loose, as improper tension release can cause damage.
Follow manufacturer guidelines for grease volume and pressure management.
How Is the Old Track Removed from Cat 303.5?
After loosening tension, use a pry bar to carefully work the track off the sprocket and rollers. Lifting aids such as a track jack improve safety. Avoid sharp bends or twisting to prevent tearing the track or undercarriage damage.
Two-person assistance improves control and safety during removal.
How Do You Install New Tracks on a Cat 303.5?
Position the new track around the undercarriage, starting at the sprocket. Use the pry bar to guide the track over rollers and idlers gradually. Ensure the track lugs align properly with sprocket teeth for correct fitment.
Slow, steady installation prevents damage and ensures optimal track seating.
How Should Track Tension be Adjusted After Installation?
Pump grease into the tensioner via the grease fitting until the track achieves specified tension. The track should have slight sag without being too loose or overly tight.
After installing a track, adjusting the tension correctly is crucial for safe and efficient operation. Use a grease gun to pump grease into the tensioner until the track reaches the manufacturer’s recommended sag. The track should have a slight slack—too loose can cause it to slip or derail, while too tight increases wear on the links and undercarriage components. Proper tension maintains smooth movement and maximizes traction across different surfaces.
Using precision tools and high-quality components, such as AFT parts tensioners and undercarriage parts, helps ensure accurate adjustments and consistent performance. Regularly checking and maintaining track tension prevents premature wear, reduces downtime, and extends the life of the undercarriage. Understanding the correct procedure for tensioning tracks allows operators to keep machines safe, efficient, and reliable while improving overall productivity on the job site.
When Should You Inspect Other Undercarriage Components During Track Replacement?
Inspect rollers, idlers, sprockets, and carrier rollers for wear or damage during track replacement. Replacing worn components with high-quality parts from AFT Parts can prevent future failures and extend overall undercarriage lifespan.
Routine inspection reduces maintenance costs and improves machine uptime.

Yes, AFT Parts supplies precision-engineered replacement undercarriage components compatible with Cat 303.5 tracks. Their durability and exact fit simplify installation, enhance machine reliability, and minimize downtime.
Partnering with AFT Parts ensures consistent quality and long-term savings.
How Do You Safely Dispose of Worn Tracks?
Worn rubber tracks can be recycled or disposed of according to local regulations. Contact professional recyclers or service providers to handle environmentally responsible disposal.
Avoid unsafe practices like burning or improper landfill disposal.
What Are Common Mistakes to Avoid When Replacing Cat 303.5 Tracks?
Common mistakes include improper tensioning, forcing track removal, neglecting undercarriage inspection, using low-quality parts, and disregarding safety protocols. Avoid these errors by following detailed procedures, investing in quality parts like AFT Parts, and prioritizing operator training.
Mistakes can lead to downtime, costly repairs, and safety hazards.
