Description
When you’re rebuilding an engine or installing new parts, those first few seconds after startup are critical. Without proper lubrication, metal parts can grind against each other before the oil pump kicks in, causing damage that’ll haunt you for years. This assembly lube coats your parts during installation and stays put until the engine gets proper oil circulation going.
What You’re Getting
- Thick, tacky formula that sticks to parts during assembly and won’t drip off
- Provides instant protection during those crucial first moments of startup
- Compatible with all engine oils so it won’t cause problems when mixed
- Easy to apply with brush or finger – spreads evenly and stays where you put it
Built for Real Farm Work
This assembly lube works on everything from small utility tractor engines to big diesel powerplants. Whether you’re doing a complete rebuild, replacing bearings, or installing a new camshaft, it gives you peace of mind knowing your parts are protected. Perfect for any engine work where you need that extra insurance against dry startup damage.
Made to Last
Lucas Oil formulates this stuff to handle the pressure and heat that comes with engine startup. It won’t wash away with the first splash of oil, but it won’t gum up your engine either. The 4-ounce size gives you plenty for most engine jobs without having a big container sitting around getting thick.
Good to Know
A little goes a long way – just coat the bearing surfaces, cam lobes, or other critical areas with a thin layer. Don’t glob it on thick or you might interfere with proper clearances. Keep the container sealed tight between uses so it doesn’t dry out on you.
