Product Overview

Squeal, belt flutter, rubber dust, a crooked pulley, or repeated drive-belt loss can trace to a seized bearing or weak tension spring. Replacing the complete idler addresses the pulley, hub, bearings, spring, bracket, and related wear points together.

The assembly includes the dust cap, roll pin, snap rings, torsion spring, hub, pulley, washers, bolts, seals, and bearings. Bobcat fitment changes by serial number, so confirm 6735884 in the machine parts catalog before ordering.

Q: How do I confirm this is the correct part? A: Use the machine serial number and match 6735884, bracket shape, pulley width and diameter, spring orientation, mounting points, and belt path.

Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket item. Brand, model, and part numbers are used only to identify compatible applications.
