Everything You Need to Know to Select the Best Engine Assembly Lube 

What Does Engine Assembly Lube Do? 

There are a couple of times you will need to use an engine assembly lube, like if you’re starting a new engine for the first time or rebuilding the engine as part of motorcycle restoration 

The purpose of engine assembly lube is to protect the engine components during an initial startup. It does this by lubricating the engine components and reduces friction when the metal surfaces rub against one another. This eliminates the possibility of dry starts and prevents the metal engine components from overheating. 

What Happens During Engine Breakin? 

As explained by How Stuff Works, aengine breakin is “… designed to begin to wear the engine evenly and smoothly with low, consistent pressure, normal operating temperature and smoothly flowing oil. The goal is to get the engine’s piston rings, which expand, contract and flex, to seat properly on the cylinder walls.” Read on for a thorough explanation of what happens during an engine break-in and why a high-quality engine assembly lube is necessary! 

1. Piston Rings Set 

The piston rings in your motor are customfit to each piston and cylinder to ensure a good seal. Also, the cylinder walls are honed, leaving a slightly rough surface. The new rings will run on the cylinder walls, which will both seat the rings and start to smooth the cylinder walls. Seating the piston rings the right way will ensure a good seal and maximize engine efficiency. 

2. Oil Pump Begins Working 

Just like every time you start your engine, it takes time for the oil pump to grab oil out of the sump, pressurize the oiling system, and get the oil out to the engine bearings and other parts of the engine to lubricate them. After break-in, the system will be filled with oil, and wear surfaces will be coated with oil so proper lubrication happens more quickly after startup. During break-in, you need something to lubricate things until your oil can get there and do its job. One thing most people don’t consider is that the assembly lube will get washed into the engine oil during the first minute of operation. Besides being a good lubricant on startup, your engine assembly lube needs to be compatible with your engine oil and should not significantly reduce or increase its viscosity. 

3. Camshafts Break-in 

The last thing that happens during break-in, especially on motorcycle engines, is that the camshaft is broken in. There is something the camshaft lobe moves to actuate the valves in every motor. This can be a flat tappet, a lifter, a rocker arm, or shimmed bucket.  On most camshafts, the first few minutes of operation after installation determine how the camshaft lobe will interact with the valve opening device. If the camshaft doesn’t get broken in correctly you can cause longterm damage to your cam or create a situation where the cam lobes will wear out quickly. Using a good engine assembly lube and breaking in your camshaft per the manufacturer’s instructions is the best way to ensure long camshaft life.
