Carbhub Stihl MS170/MS180 38mm Cylinder Piston Crankshaft Kit — Complete Engine Rebuild, Direct-Fit

If your Stihl MS170 or MS180 (model 018) is showing reduced power, heavy smoke, or oil leaks, this Carbhub aftermarket engine kit supplies the core components needed to restore compression and reliable running. The kit replaces OEM parts 1130 020 1208 and 1132 030 0402 and centers on a 38mm cylinder bore, offering a direct-fit replacement designed for hobbyist and light-professional saw maintenance.

How will this kit affect my saw's performance?

Installing a new cylinder, piston and crankshaft renews compression, reduces blow-by, and can recover lost cutting power when wear has developed. Because the kit includes precision bearings and seals, it helps stabilize crank movement and reduces oil contamination.

• Restores compression with a new 38mm piston and matching cylinder.
• Replaces worn crankshaft to eliminate wobble and vibration.
• New oil seals and bearings minimize leaks and friction.

Will these parts fit my Stihl MS170 or MS180 without modification?

Yes — the components are engineered to match the dimensions and mounting pattern of Stihl MS170 and MS180 (018) models. The kit swaps in for OEM numbers 1130 020 1208 and 1132 030 0402, so installation is generally direct when the saw’s case and mounting surfaces are in serviceable condition.

• Designed for MS170 and MS180 (018) compatibility.
• Matches OEM part references for straightforward replacement.
• Includes all necessary fasteners and basic fittings to mount the cylinder.

What exactly is included in the package?

The kit bundles the engine parts you need to perform a full small-engine top-end and crank replacement. You receive both rotating and sealing components so you can complete a thorough rebuild without sourcing extra items.

• 1x cylinder and 1x 38mm piston (assembled)
• 1x crankshaft and engine pan plus 4 mounting screws
• 2x crank bearings, 2x oil seals, 1x piston pin bearing, and 1 spark plug

How should I approach installation and compatibility checks?

Before starting, compare the old parts’ bore and mounting holes with the new components and inspect the crankcase for damage. Basic mechanical skills and common small-engine tools suffice, but if you’re unsure, a professional tune-up shop can complete the job correctly and verify timing and clearances.

• Confirm 38mm bore matches your original cylinder size.
• Check gasket surfaces and crankcase integrity before assembly.
• Use recommended torque values and verify spark plug gap after install.

Who is this for? This Carbhub replacement engine kit suits homeowners, landscapers and occasional pro users who need a cost-effective way to revive a worn Stihl MS170 or MS180 (018). It’s ideal for anyone comfortable with small-engine repairs who wants an OEM-replacement fit and a complete set of parts to avoid multiple orders.
