Q

Bearing clearances in small high-speed diesel engines should be measured using __________.

🔍 Key Concepts

• Bearing clearance in engine main and connecting rod bearings • Common shop tools for measuring very small clearances • How mechanics check clearance between a shaft/journal and its bearing without disassembly

💭 Think About

• Think about which tool is specifically designed to be placed between two surfaces, tightened to normal torque, and then compared to a printed scale to find clearance. • Ask yourself which option is commonly used on crankshaft main and connecting rod bearings in small diesel and automotive engines. • Consider which tools from the list measure length directly, and which one is made to deform and indicate clearance.

✅ Before You Answer

• Verify which option is a soft, calibrated material that flattens under pressure and is read against a scale. • Eliminate tools that are mainly used for flat surface calibration (like precision blocks) rather than running clearances. • Check which tool is most common in engine bearing inspection procedures in manuals for high‑speed diesels and automotive engines.
