Description
When you’re rebuilding an engine or assembling critical components, that first startup is when most wear happens—before oil pressure builds and everything gets properly lubricated. Assembly lube solves this problem by coating parts with a thick, protective film that stays put until your engine oil takes over. It’s like giving your freshly rebuilt engine a fighting chance right from the first turn of the key.
What You’re Getting
- Thick, clingy formula that won’t drip off parts while you’re working
- Superior protection during initial startup when regular oil hasn’t reached all components yet
- Dissolves completely into your engine oil—no cleanup or removal needed
- Works on bearings, cam lobes, lifters, and other critical wear surfaces
- Convenient 8-ounce bottle gives you plenty for most engine rebuilds
Built for Real Farm Work
Whether you’re rebuilding the engine in your old reliable work tractor or freshening up a diesel that’s been working hard all season, this assembly lube is essential insurance. It’s perfect for coating main and rod bearings, camshaft lobes, valve stems, and anywhere metal meets metal during that critical first few seconds of operation.
Made to Last
Lucas Oil knows farm engines work harder and longer than most, so this assembly lube is formulated to provide maximum protection during startup. The thick consistency stays where you put it, even if parts sit for days or weeks before final assembly and startup.
Good to Know
Apply a thin, even coat to all bearing surfaces, cam lobes, and lifters before assembly. Don’t overdo it—a little goes a long way, and too much can actually slow oil flow initially. The lube will mix with your engine oil during operation, so there’s no need to drain it out later.
