🔍 Key Concepts

• Piston skirt function in guiding the piston in the cylinder and controlling side clearance • How wear on a piston skirt affects compression, blow-by, and piston stability • Typical temporary repair methods used in small marine diesels when spares are not available

💭 Think About

• Which option would help restore proper fit between the piston skirt and cylinder without removing more metal? • Which method is commonly used in the field as a quick, low-cost way to take up excess clearance on worn pistons? • Which choices might actually weaken the piston or change critical dimensions, making the problem worse rather than better?

✅ Before You Answer

• Identify which options remove material versus which displace or add material to reduce clearance. • Consider whether changing ring land groove dimensions is safe for ring sealing and strength. • Ask whether any option would likely be considered only a temporary emergency measure, not a standard overhaul practice.
