WHEN TO REPLACE – COMMON SYMPTOMS

KEY FEATURES & BENEFITS

BEFORE YOU BUY – CRITICAL CHECKS

⚠️ VERSION COMPATIBILITY – MOST IMPORTANT

This is the early version piston (1142-030-2006). Later MS462 models use piston 1142-030-2009. These are NOT interchangeable. To verify which version you need:

1. Check your saw's serial number

2. Inspect the existing piston part number if available

3. Consult your STIHL dealer for version identification

⚠️ CYLINDER CONDITION IS CRITICAL

This standard 52mm piston requires a reusable cylinder. Inspect for:

• Deep scoring or gouges

• Out-of-round condition

• Visible damage above intake/exhaust ports

⚠️ DIAGNOSE ROOT CAUSE FIRST

New piston will fail again if underlying issues aren't fixed:

• Fuel mix ratio must be 50:1

• Check for air leaks (crankshaft seals, intake boot)

• Inspect carburetor for lean condition

• Replace dirty air filter

FREQUENTLY ASKED QUESTIONS

Q: How do I know if I need the early version (2006) or later version (2009)?
A: Check your saw's serial number or the part number on your existing piston. If unsure, consult your STIHL dealer with your saw's serial number.

Q: Will this fit my MS462 if I have the 2009 piston?
A: No. The early (2006) and late (2009) pistons are NOT interchangeable. You must use the correct version for your saw.

Q: Do I need to hone my cylinder?
A: If the cylinder is in good condition with visible cross-hatch and no scoring, light honing is recommended. If glazed, deglazing is necessary. If deeply scored, cylinder replacement is required.

Q: What oil ratio should I use after rebuild?
A: STIHL specifies 50:1 with high-quality two-stroke oil. Never exceed this ratio.

Q: How long will this piston last?
A: With proper installation, correct fuel mixture, and clean air filtration, expect 500+ hours of professional use.
