ATHENA Cylinder Base Gasket ref. S410089006001 for HUSQVARNA TC, TE, TXC 250, 310, 450, 510 2003-2010

ATHENA offers this cylinder base gasket for HUSQVARNA TC, TE, TXC 250, 310, 450, 510 2003-2010. The base gasket sits under the cylinder, on the crankcase. Crushed when tightened, it cannot be reused: replace it every time the cylinder comes off.

Why does the thickness matter?

The benefits:

• The OE thickness keeps the cylinder height intended by the manufacturer.
• Another thickness lets you correct piston-to-head clearance after machining or adjust the port timing of a 2-stroke.
• A new gasket keeps the bottom end sealed against oil and gases.

Why choose ATHENA?

Athena, founded in 1973 by Giovanni Mancassola near Vicenza and based in Alonte (Italy), designs gaskets, pistons and cylinder kits; it supplies original equipment to manufacturers such as KTM, Ducati, Fantic and Triumph.

When should you replace the base gasket on your HUSQVARNA TC 450?

Every time the cylinder comes off: piston change, top-end rebuild or cylinder inspection. Oil or mixture seeping at the base of the cylinder also points to a tired gasket.

No manufacturer figure in hours for this model. Cross-Mania guideline: compression check every 30 h of hard use and every 60 h of leisure riding.

Specifications and fitting tips

• Manufacturer part numbers: S410089006001 (OE), S410220006023 (0.10 mm), S410220006024 (0.20 mm), S410220006025 (0.30 mm), S410220006026 (0.50 mm), S410220006027 (0.60 mm)

Choose the thickness from the list. "OE" is the factory thickness; another thickness is used to set the cylinder height after a rebuild (piston-to-head clearance, port timing on a 2-stroke).

Cross-Mania tip: Choose the OE thickness if the cylinder and head have not been machined; if in doubt, measure the squish with solder wire before final assembly.
