741348 Spectro Assembly Lubricant Bottle of 4 Oz

Spectro Assembly Lubricant provides essential protection during the critical initial startup of a rebuilt Harley-Davidson engine. This heavy-bodied lubricant is fortified with anti-scuff polymers designed to coat and plate internal components like cam lobes, gears, rings, and bearings. By creating a durable barrier, it prevents metal-to-metal contact and wear before the primary oiling system reaches full pressure. It is fully compatible with all petroleum-based oils and features anti-rust properties, making it suitable for protecting engine or transmission parts during prolonged storage. Spectro Oils of America formulated this lubricant to ensure total starting protection for precision mechanical assemblies.
