Genuine Husqvarna Gasket Set - 537 21 26-01
The Genuine Husqvarna 537212601 Gasket Set is a comprehensive sealing solution for the high-torque 570 and 575 XP professional chainsaw series. This factory-original kit provides all the essential gaskets required for a top-end rebuild or crankcase service, ensuring your saw maintains the internal compression and vacuum integrity required for peak performance.
Total Engine Integrity
Using OEM Husqvarna gaskets is vital during engine reassembly. Aftermarket gaskets often vary in thickness, which can dangerously alter your squish gap or lead to catastrophic air leaks. These factory gaskets are precision-cut from heat-resistant materials designed to withstand the high thermal expansion rates of professional-grade 70cc+ engines.

🛠️ Mechanic's Tip:
Never reuse old gaskets, as they take a "set" once compressed. Before installing new gaskets, ensure all mating surfaces are perfectly flat and clean—use a plastic scraper to avoid gouging the aluminum magnesium crankcase. We recommend applying a very thin film of two-stroke oil to the cylinder base gasket to help it seat, but avoid using RTV or liquid sealants unless specifically called for in the workshop manual.
