• Positioned at the opposite end from the sprocket, the tension idler is crucial for maintaining proper track tension.
• It expands as grease is pumped into the tensioner, tightening the rubber track.
• Often referred to as the larger roller or pulley due to its role and size.

• While the idler wheel itself is universal across several models, the mounting arms (yokes) differ in length.
• We offer the idler wheel separately, allowing you to reuse your existing mounting arms for a perfect fit.
• The idler we offer comes with ten-and-a-half-inch-long mounting arms.
• Models requiring shorter mounting arms should opt for part number 140-4009.

• It's common practice to reuse mounting brackets across various manufacturers. Most dealerships offer the idiler wheel individually, facilitating easier replacement.

• This idler is also compatible with certain CAT 302.5 models.
• Ensure your existing mounting arms fit the ten-and-a-half-inch requirement. If not, consider alternate part number 140-4009.
