Spectro Assembly Lubricant is a specialized heavy-duty lubricant formulated to protect internal Harley-Davidson engine components during the critical initial start-up phase. Fortified with anti-scuff polymers, this lubricant plates surfaces such as cam lobes, piston rings, gears, and bearings to prevent metal-to-metal contact before oil pressure is fully established. Its high-cling formula ensures total protection during re-assembly and repair, while built-in anti-rust properties safeguard parts during prolonged storage. Compatible with all petroleum-based oils, this Spectro lubricant is an essential workshop consumable for ensuring the longevity and proper break-in of rebuilt engines and transmissions, providing protection for any mechanical overhaul.
