Direct replacement for Husqvarna chainsaws

This kit provides a muffler bolt and gasket designed to fit Husqvarna models 340, 345, 346, 346XP, 350, 351 and 353. It replaces original equipment numbers 503202987, 503204587 and 503862501 for a precise factory match.

Verify your model and existing hardware

Confirm the saw is one of the listed Husqvarna models before ordering. Check that the current muffler bolts and gasket are the only items needing replacement; damaged studs or a warped muffler flange will require additional parts not included in this kit.

Seals the exhaust on two-stroke engines

The gasket creates a gas-tight seal between the muffler and cylinder while the two bolts secure the joint against vibration. Installing the kit restores proper back-pressure and prevents exhaust leaks that reduce power and increase noise on these single-cylinder petrol saws.

Questions about this item

Does the LAHDEK M1141 kit include everything needed to refit the muffler on a Husqvarna 353, or are extra bolts required?

The package supplies one muffler gasket and two muffler bolts, matching the OEM quantities for the listed saws, so no additional fasteners are needed for installation.

How do I confirm the LAHDEK M1141 kit fits my specific Husqvarna model among the 340, 345, 346, 346XP, 350, 351 and 353?

Compare the OEM numbers on your existing hardware — 503202987, 503204587 or 503862501 — with the kit's cross-reference; a match means the kit is correct for that saw.

What does the two-bolt, one-gasket configuration mean when reassembling the exhaust on a 346XP?

It provides both mounting bolts and the sealing gasket in one pack, letting you replace all three wear items at once and restore a proper exhaust seal on the 346XP.
