Rubber tracks sized 450x86Qx56 indicate a track circumference of 450 inches, 86 pitch links with a “Q” pitch type, and a width of 56 inches. This size specification is crucial for ensuring a proper fit and optimal performance for your machinery. AFT Parts provides precision-engineered rubber tracks of this size compatible with major excavator and heavy equipment brands.
What Do the Components of 450x86Qx56 Rubber Track Size Mean?
In the size 450x86Qx56:
-
450 denotes the total length of the rubber track in inches (track circumference).
-
86Q specifies 86 pitch links with a “Q” pitch design or notch type that determines how the track meshes with the sprocket.
-
56 is the track width in inches, reflecting the internal track dimension responsible for ground contact and machine stability.
Understanding these helps ensure correct track selection.
How Is Track Length Measured for a 450-Inch Rubber Track?
Track length refers to the inside circumference of the track loop as it sits around the undercarriage. Measuring accurately prevents slack or over-tight tension, both of which can cause premature wear or track failure.
What Is the Significance of the “Q” in 86Q Pitch Link Count?
The “Q” in 86Q denotes a specific pitch link style or profile that ensures compatibility with certain sprocket designs. Matching the correct pitch type is vital for smooth power transmission and to prevent excessive undercarriage wear.
Why Does Track Width of 56 Inches Matter?
Width determines the total surface area contacting the ground. A 56-inch width must align with the undercarriage frame to maintain machine balance, improve flotation on soft terrains, and avoid excessive wear to track edges or rollers.
Which Machines Utilize Rubber Tracks Sized 450x86Qx56?
This size is commonly found on larger excavators and robust heavy machinery requiring wide tracks and specific pitch link designs for demanding terrains. Check manufacturer specifications or consult suppliers like AFT Parts to ensure proper size match.
How Can Incorrect Rubber Track Sizing Affect Equipment Performance?
Incorrect length, pitch style, or width can cause poor traction, track slippage, sprocket damage, and accelerated wear of the undercarriage components. Ensuring accurate sizing minimizes downtime and repair costs.
How Do I Measure My Machine’s 450x86Qx56 Track?
Measure track length by laying the track flat or measuring the inside loop when mounted. Count pitch links engaged by the sprocket and confirm pitch style ("Q"). Measure width across the rubber contact surface. Manufacturer or aftermarket guides—such as those from AFT Parts—offer detailed instructions.
Where Can I Purchase 450x86Qx56 Rubber Tracks?
AFT Parts and authorized heavy equipment dealers offer premium rubber tracks in this size built to OEM or higher standards. These sources guarantee quality, warranty support, and expert advice tailored to specific equipment and working environments.
Are Aftermarket 450x86Qx56 Rubber Tracks Reliable?
Yes. Leading aftermarket brands like AFT Parts produce tracks matching or exceeding OEM quality using advanced materials and quality assurance processes, providing cost-effective, durable solutions.
When Should I Replace Rubber Tracks Sized 450x86Qx56?
Replace when noticeable tread wear, cracks, or damaged pitch links appear. Proactive inspection, especially after rigorous use or severe environmental exposure, prevents machine downtime and extends undercarriage lifespan.
What Maintenance Steps Extend the Lifespan of 450x86Qx56 Rubber Tracks?
Regularly clean debris, maintain manufacturer-recommended tension, avoid extreme maneuvers on hard surfaces, and inspect frequently for wear or damage. Guidance from suppliers like AFT Parts optimizes maintenance routines.
Could Worn Rubber Tracks Cause Damage to Other Undercarriage Parts?
Absolutely. Poorly fitting or worn tracks stress rollers, sprockets, and idlers, expediting component failure. Maintaining correct track size mitigates this risk.
