Does anyone have any ideas on a good source for old seals and bearings? I need one for my blower snout and my engine.
Here is the National catalog. You can look them up by size. Sometimes a number becomes obsolete but another seal can be used National-Indust-Seals-Catalog_7707.pdf (timken.com)
A good industrial supply house. They should be able to cross reference the numbers or inner,outer dia and thickness
