Introduction to key points:

• This is a high-quality aftermarket front idler, part number 772456-37100, suitable for specific Yanmar mini excavator models:
  • Yanmar VIO 20-2
  • Yanmar VIO 20-3

• If your track looks like it's stretching or comes off during turns, it's likely time to replace your idler.
• The old idler might look fine at first glance. However, a new idler gets deeper into the guide system, indicating the old one might be more worn out than it seems.

• Rubber tracks are made with steel cords to prevent stretching under usual conditions beyond what the tensioner can adjust.
• The tensioner is there to steadily pull the track tighter as parts of the undercarriage wear out.
• The wear of the sprocket, track link, and idler can create slack in the track which, after a certain point, requires part replacement.
• While replacing a sprocket on a worn track isn't recommended, changing the tension idler can recover several inches of slack, improving undercarriage tension.

• Each Yanmar VIO20-2 and VIO20-3 series mini excavator typically has one tension idler on each side.
• If your excavator is a newer model than the -3 series, confirm compatibility with us before making an online purchase.
