Getting Your Bearings

Engine bearings have a tough job to do for such a small component. They must support big loads on a thin film of oil (between .0001-.0004? thick) between themselves and the crankshaft journals to prevent metal-to-metal contact. One of the biggest causes of bearing failures is dirt and debris that enters into the oil pan

Removing Crankshaft Pilot Bearings (#3)

Soak the paper in water and stuff it into the hole, and then drive it in with a bolt or other tight fitting tool. Keep cramming in more wet toilet paper until the bearing pops out.   In my experience, this method is much quicker than using bearing removal tools and is way cleaner than

Removing Crankshaft Pilot Bearings Revisited (#4)

When removing a crankshaft pilot bearing, the easiest way is to use modeling clay or Play-Doh. Pack the clay into the hole first by hand, and then hammer it in with a tight fitting bolt or blunt chisel. It doesn’t take much force to make the bearing pop out. There is no mess, and the

Engine Bearings and Crankshafts: Best Friends Forever (BFFs)

Bearings appear to be such simple engine components. On the surface, they’re just half-circles of metal whose only purpose is to reduce friction between and support moving parts. The engine bearing has to establish and maintain a film of oil between moving and stationary parts to prevent wear to expensive engine components. They look like

A micrometer with aball anvil must be used to fit the curvature of the bearing I.D., asshown in Figure 1. Standard flat anvil

Influence of Grooved Main Bearings on Performance

It’s essential to understand that bearings depend on a film of oil to keep them separated from the shaft surface. This oil film is developed by shaft rotation. As the shaft rotates it pulls oil into the loaded area of the bearing and rides up on this film much like a tire hydroplaning on wet
