Product Overview
Belt chirp, wandering, repeated belt loss, a bouncing tensioner arm, or pulley bearing noise can stop a machine before the belt itself looks worn out. Once pulley alignment, accessory bearings, belt length, and contamination are checked, replacing a weak or rough tensioner restores controlled belt load.
This tensioner is used across equipment with related engine installations, but serial breaks matter. Compare arm angle, pulley diameter and grooves, mounting boss, offset, spring direction, and every original reference before ordering. A misaligned accessory can quickly ruin the new part.

Northline Parts does its best to list all known compatible models. The correct part may fit an application that is not shown above.

Frequently Asked Questions
Q: Can a tensioner look good but still be bad? A: Yes. Its spring can weaken and the pulley bearing can roughen without an obvious crack.
Q: Why do serial numbers matter? A: Manufacturers can change brackets, engines, and belt drives within the same model.
Q: Should I replace the belt too? A: Replace it if cracked, glazed, stretched, oil-soaked, or damaged by the old tensioner.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
