Frequently Asked Questions

When do I apply assembly lube during engine building?

Coat all internal bearing surfaces, camshaft lobes, valve stems, pushrods, and rocker arms before final assembly to protect against dry running.

Do I need to drain or flush assembly lube before first startup?

No — assembly lube is formulated to blend with all motor oils, so it disperses naturally once you run the engine.

Will this work on both Harley and Indian engines?

Yes — this assembly lube is compatible with all V-twin motorcycle engines, including Harley-Davidson and Indian Motorcycle powerplants.

Is one 4 oz bottle enough for a complete engine rebuild?

One 4 oz bottle is sufficient for most single-engine rebuilds. Shops doing multiple builds may want to stock the 12-case pack.
