Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
- John Deere 6120, 6220, 6320 and 6420 are among the supported applications found in cross-reference data
- Additional 6000- and 7000-series tractors may use the same references; verify by serial number and alternator
Product Overview
This pulley sits on the alternator drive and must match the belt groove count, pulley offset and alternator shaft arrangement. A worn or damaged pulley can contribute to belt noise, poor belt tracking or charging-system drive problems, but belt tensioner and alternator bearing condition should be checked at the same time.
Cross-reference data for AL161112 and AL157595 supports a broad range of John Deere tractor applications, including commonly listed 6120, 6220, 6320 and 6420 models. The original CSV title named newer 6R210/6R230/6R250 tractors, but that application was not sufficiently supported in the references reviewed, so it has intentionally been removed from this listing title.
Match the part number and eight-groove profile to the original pulley. John Deere used multiple alternator suppliers and pulley arrangements across model and serial ranges.
