FAQs

Is this a genuine Husqvarna part?

No, this is a high-quality aftermarket replacement part manufactured by RocwooD.

Does this kit include a new spark plug?

No, the kit includes the cylinder, piston, rings, gudgeon pin, and circlips only.

What should I do if my current piston is not 44mm?

Do not install this kit. If your chainsaw has a different bore size, this assembly will not function correctly and may damage the engine.

Is a new base gasket included?

It is recommended to purchase a new base gasket separately, as one may not be included in all kit configurations.

Will this fit a Husqvarna 345?

No, this kit is specifically designed for models with a 44mm bore like the 350, 351, 353, and 346XP.

Troubleshooting

Engine has low compression after install

Ensure the rings are properly seated in the piston grooves and the cylinder bolts are torqued to the manufacturer's specification.

Saw will not start

Check that the spark plug is seated correctly and verify that the cylinder base gasket is creating an airtight seal.

Pros and Cons

Pros

  • Comprehensive kit includes all essential internal components for a rebuild
  • Cost-effective alternative to OEM parts
  • Perfect fit for the popular Husqvarna 350-353 series
  • High-quality materials ensure long-lasting performance

Cons

  • Non-genuine aftermarket component
  • Requires mechanical expertise to install correctly
  • Compatibility depends strictly on matching the 44mm piston diameter

Setup, Compatibility & Care

To install this assembly, you must remove the starter housing, top cover, carburetor, and the old cylinder block. It is highly recommended to replace the base gasket and crankshaft seals simultaneously to ensure no air leaks occur during operation.

Compatibility

This kit fits the following Husqvarna models:

  • 350
  • 351
  • 353
  • 346XP

Warning: Always verify your current piston diameter is 44mm before ordering, as some variants of these saws may use different bore sizes depending on the production year.

Care

After installation, use a high-quality 50:1 fuel-to-oil mix. Avoid running the saw at full throttle for extended periods during the first two tanks of fuel to allow the rings to properly seat against the cylinder wall.
