MOTOALL Cylinder Piston Gaskets Kit for Stihl TS410/TS420 — Cylinder, Piston Gaskets & Oil Filter

MOTOALL 4238 020 1202 Cylinder piston gaskets kit is a replacement service kit designed to restore sealing and engine components on Stihl TS410 and TS420 cut-off saws.

This replacement kit bundles a cylinder, piston gaskets, oil filter, oil bubble, and rubber shock absorbers to help rebuild the top end and related components on compatible Stihl TS410 and TS420 models. It replaces part numbers 4238 020 1202, 4223 020 9400, and 42230209400. The package is intended for owners who need to refresh sealing surfaces and replace worn small parts; it does not include a decompression valve, though the cylinder has a threaded hole to accept one if required.

How do I know this kit fits my Stihl TS410 or TS420?

Confirm fitment by matching your machine’s model and part numbers against the listed replacements (4238 020 1202, 4223 020 9400, 42230209400). Check the year, model and engine configuration before ordering to avoid compatibility issues. If you’re uncertain, compare the existing cylinder and gasket geometry with photos or contact seller support for clarification.

• Compatible models: Stihl TS410, TS420 cut-off saws
• Replaces the listed part numbers exactly
• Cylinder includes threaded hole for optional decompression valve
• Verify Year/Make/Model before purchase

What components are included and what do they do?

The kit includes a replacement cylinder, piston gaskets, an oil filter, an oil bubble (oil sight or breather component), and rubber shock absorbers. Together these parts renew sealing surfaces, manage lubrication flow, and reduce vibration between the saw's engine and chassis. They are intended to be used in a top-end or mid-level service rather than a full engine overhaul.

• Cylinder — restores combustion chamber and sealing surface
• Piston gaskets — replace worn seals to prevent leaks
• Oil filter and oil bubble — maintain cleaner lubrication
• Rubber shock absorbers — reduce mounted vibration and wear

Can I install this kit myself and what should I prepare?

Experienced DIYers comfortable with small-engine disassembly can install these parts, but top-end work requires correct torque specs, gaskets, and clean surfaces. Prepare basic engine tools, a service manual for torque and timing settings, and a clean workspace. If you lack experience, consider professional installation to avoid damage or improper sealing.

• Needed tools: socket set, torque wrench, gasket scraper, cleaning solvent
• Reference: Stihl service manual for TS410/TS420
• Check for additional worn parts before reassembly
• Note: decompression valve not included; optional install if desired

What should I watch for after replacing these parts?

After installation, run the saw at low throttle to check for oil or compression leaks and proper start-up behavior. Listen for unusual noises and monitor oil pressure or sight indicators if equipped. Recheck fasteners and seals after initial break-in and avoid heavy use until the engine runs smoothly.

• Inspect for oil leaks around cylinder and gaskets
• Confirm normal compression and starting
• Retorque bolts after short run-in per manual
• Replace decompression valve separately if needed
