Description
This is a CNC machined billet hub that bolts to the flywheel of the small block Briggs Vanguard horizontal engine. This hub is used when repowering equipment that had an OEM Onan engine with the following specs. Included in this is the John Deere Garden tractor 316, 318 and the 420 models. This hub has a 2” dia pilot .375 deep and a 4 bolt 5/16-18 on a 2-3/4 BC. Includes the hub and 4 mounting bolts.
Please note: There are 2 options for bolts. 5/16-18 and 8mm x 1.25. You will need to figure out what thread size is in your flywheel. There is no way for us to know.
