We don't have more detail on this one beyond what the part number and its alternate form tell us. The catalog association with magneto drive components suggests it's a bearing that supports the magneto shaft or drive assembly, but we can't confirm exact fitment from what's on file.
If you're chasing this for a magneto rebuild, call the shop and we'll confirm fitment before you order.
