Bearing "crush" as applied to diesel engine main bearings, will result in __________.

🔍 Key Concepts

• bearing crush and how it affects a bearing shell in its housing • the intended purpose of crush during installation vs. what happens when crush is incorrect • relationship (or lack of it) between crush and temperature, journal damage, and bearing shell damage

💭 Think About

• Think about what “crush” physically means when a thin shell bearing is slightly oversized for its bore: what does that force the bearing to do when the cap is tightened? • Ask yourself which option describes the normal, intended result of proper crush, not the consequences of a problem or failure. • Consider which choices describe secondary effects (things that happen after a failure) versus the primary purpose of having crush in the first place.

✅ Before You Answer

• Be clear whether the question is talking about proper bearing crush by design or excessive/insufficient crush as a defect. • Visualize a split-shell bearing in a connecting rod or main bearing cap: how does crush keep it from spinning or moving in the housing? • Before choosing, separate in your mind what is cause (what crush does directly) and what is effect (what might happen if something goes wrong).
