⚠️ CRITICAL FITMENT NOTE:
This ring set is sized for 52.00 mm STANDARD BORE x 1.2 mm THICKNESS cylinders only. DOES NOT FIT 036/MS360 (50mm), 039/MS390 (54mm), 088/MS880 (62mm), or oversize bores (+0.25/+0.50/+0.75mm). Verify your engine model, cylinder marking, and bore measurement before ordering. Incorrect ring dimensions will cause piston seizure, loss of compression, or catastrophic cylinder damage.

🔧 Installation Guide (Professional Small Engine Technician)

Preparation: Remove cylinder head, muffler, and carburetor; extract piston from cylinder; clean cylinder bore thoroughly
Cylinder Inspection: Measure bore at 3 heights to confirm 52.00mm STD; check for scoring, taper, or out-of-round (<0.03mm tolerance)
Ring Installation: Install 2nd (taper-faced) ring first (mark "TOP" facing up), then chrome-plated top ring; stagger end gaps 180° apart
Gap Verification: Check end gaps in cylinder bore per Stihl spec (typically 0.20-0.40mm); file gaps if necessary using ring gap tool
Piston Reassembly: Install rings onto piston grooves (ensure free rotation without binding); lubricate rings and cylinder walls with 2-stroke oil
Cylinder Installation: Use ring compressor or careful hand compression to install piston into cylinder; avoid ring damage during insertion
Final Assembly: Reinstall cylinder head, muffler, carburetor; set carburetor adjustments per manual; verify spark plug gap
Break-In Procedure: Start engine; run at idle 2-3 minutes; operate at light load for first 1-2 fuel tanks; avoid full throttle during break-in

⚠️ Critical Installation Notes:
• CONFIRM 52.00mm BORE x 1.2mm THICKNESS before installation – incorrect size causes immediate engine failure
• Stagger ring end gaps 180° apart to prevent blow-by and loss of compression
• Use ONLY Stihl-approved 2-stroke oil mixed at 50:1 or 40:1 per equipment manual – improper mix causes piston seizure
• Do not over-torque cylinder head bolts – follow Stihl torque spec (typically 8-12 Nm)
• Follow OEM break-in procedure: light load for first 1-2 fuel tanks, then gradual power increase
• Professional small engine technician installation recommended for warranty validity

❓ Frequently Asked Questions

Q: Will this fit my Stihl MS461 chainsaw?: A: Yes! Part No. 1122 030 2000 is compatible with MS461, MS460, and 046 chainsaws with 52mm bore cylinders. Verify cylinder marking and bore measurement [[1]][[4]].
Q: Does this kit include the piston, pin, and clips?: A: No – this listing is for the piston ring set only (2 rings). Piston, piston pin, and retaining clips are sold separately. Order a complete piston kit if replacing the entire assembly.
Q: Can I use this on a Stihl TS500i cut-off saw?: A: Yes – the TS500i uses a 52mm bore 2-stroke engine compatible with this ring set. Verify your cylinder is not oversize before ordering [[9]][[12]].
Q: What's the correct end gap for these rings?: A: Stihl specifies 0.20-0.40 mm end gap for 52mm 2-stroke engines. Measure in the cylinder bore and file gaps if necessary using a ring gap tool.
Q: What fuel/oil mix should I use after installation?: A: Use ONLY Stihl-approved 2-stroke oil mixed at 50:1 (or 40:1 for high-performance applications) with fresh 89+ octane gasoline. Never use automotive motor oil or ethanol-blended fuel over 10%.
