Should I use assembly lube on main bearings?

A thin coating of assembly lube should be applied on all high-friction, high-load surfaces including rod, main and cam bearings. Assembly lubes are one of the most important parts of an engine build.

Can I use grease as assembly lube?

Well, some assembly lubes are essentially grease, which is much thicker than motor oil. Applying grease to parts will ensure it stays exactly where you put it. It now must make way for the motor oil to protect the engine. If it’s excessively thick, however, it can clog narrow oil passages and prevent good oil flow.

Should I use assembly lube?

No! Assembly lube is a must for anything you are putting together in your car or bike. All the mechanical devices on your car or motorcycle are designed to be lubricated to keep things running smoothly and reduce friction. Friction is the enemy of all machines because it creates heat and heat breaks things.

Do you lube both sides of main bearings?

No, only lube the bearings on the journal side (where they touch the crank). You do not want to lube the side that touch the rods, or where the mains fit into the block.

What type of lubrication is best for the engine?

The most popular lubes are usually moly-based (Molybdenum Disulfide) and are designed to operate at high temperatures. Newer compounds are manufactured with additives that hold up better under extreme pressures and also act as rust inhibitors much like the compound Cosmoline.

Should you use assembly lube on piston rings?

Don’t wipe the oil off. You can use assembly lube on the piston pin, but the skirt and lands should only have a light wipe with motor oil. Do not oil the rings unless specifically told to do so by the manufacturer. The oil that is already on the bore surface is all that they need.
