Question 1 of 27070

Diesel engine main and connecting rod precision bearings are made in halves. Each half exceeds one-half the bearing circumference by a small amount. The small amount is termed __________.

🔍 Key Concepts

• Diesel engine bearing construction – why precision bearings are made in two halves • The purpose of a slight interference fit between bearing shell and housing • Difference between running clearance (oil film space) and how the bearing is held in place

💭 Think About

• Think about what happens when the two bearing halves are installed in the rod and cap – what keeps the shells from spinning inside the housing? • Which term describes the extra material that makes the bearing slightly larger than the housing bore so it will be squeezed into place? • Which choice instead refers to the intentional gap for the oil film between the journal and the bearing surface?

✅ Before You Answer

• Identify which option is associated with the interference fit of the bearing shell in its housing, not the gap between shaft and bearing • Eliminate the terms that relate to axial load or thread geometry, since those are not describing bearing shell fit • Confirm that the correct term describes a condition that helps prevent the bearing from turning or working loose in service
