LAHDEK Crankshaft Oil Seal 5-Pack for Husqvarna 340 345 350

Five-pack crankshaft oil seals

This five-piece set supplies replacement crankshaft oil seals for Husqvarna 340, 345 and 350 chainsaws. Each seal matches OEM reference 503 93 23 02 for direct fitment on the listed models. The pack is intended for owners and technicians servicing these specific 2-stroke single-cylinder saws. Having multiple seals on hand simplifies scheduled rebuilds or unexpected leaks.

Capacity and headroom for seal replacement

Five seals provide enough units for several complete crankcase reseals on the supported saws. They handle the sealing demands of the original petrol-powered engines without modification. The set runs out when all five seals have been used or when servicing a model outside the 340, 345, 350 range. No additional hardware or gaskets are included in the package.

Upgrading from worn or single seals

This pack replaces individual OEM seals purchased one at a time, reducing downtime and per-unit cost. The jump is worth it when a workshop or owner performs repeated crankcase work on the compatible Husqvarna models. It does not suit saws with different crankshaft dimensions or non-Husqvarna brands. Buyers needing seals for other displacements should verify fitment before ordering.
