🔍 Key Concepts

• Use the TDC degree value for No. 11 cylinder from the MO-0039 table • Understand that 106° after TDC means adding crank angle to that cylinder’s TDC position • Remember that the flywheel scale is referenced to No. 1 cylinder and wraps around at 360°

💭 Think About

• What is the top dead center degree for cylinder No. 11 according to the table, and how is it measured on the flywheel? • If the exhaust opens 106° after that TDC, how many total degrees from 0° (No. 1 TDC) will the crankshaft have turned? • If your total is more than 360°, how should you convert it back to a reading on the 0°–360° flywheel scale?

✅ Before You Answer

• Be sure you are using the No. 11 cylinder’s TDC value from the correct column • Make sure you add 106° to the No. 11 TDC value before comparing to the choices • If your sum exceeds 360°, subtract 360° to find the equivalent flywheel reading between 0° and 360°
