Description
Overview:
This Cylinder Base Gasket is a genuine Husqvarna/Partner part for professional petrol saws and cutters, including the K1250 and 3120 ranges. It sits between the cylinder and crankcase to create a tight, stable seal that maintains correct compression and prevents air, fuel, and oil leaks. Made from durable, heat- and fuel‐resistant gasket material, it is built to handle high engine temperatures and vibration. Using the correct base gasket helps the engine start reliably, idle cleanly, and deliver full power under load. Supplied to OEM specification with part numbers 503 13 46 01 and 503134601, it offers an accurate fit with no trimming required, supporting consistent performance and long service life in demanding cutting and forestry work.
