ATHENA Piston Pin 18x12x56 mm for HUSQVARNA CR 360, WR 360 and KTM EXC 360, EXC 380, SX 360, SX 380 1992-2005

On KTM EXC 360, EXC 380, SX 360, SX 380 and HUSQVARNA CR 360, WR 360 from 1992 to 2005, the ATHENA 18x12x56 mm S41317004 piston pin fits in place of the original part. Small but heavily loaded, the pin transmits the piston's thrust to the connecting rod. A marked or oval pin creates play and noise, and wears the small end.

When to replace it?

• Metallic knocking at idle or when closing the throttle.

• Noticeable play between the pin and the small end or the piston bosses.

Check the pin at every piston change and replace it as soon as it is marked, blued or has play. A new pin always goes in with new circlips.

Fitting tips

1. Check that the pin diameter and length match your piston (see specifications).
2. Oil the pin, the small end and the piston bosses, then push the pin in by hand, without forcing it.
3. At the same time, check the small-end needle bearing.
4. Fit new piston pin circlips, gap opposite the notch, and check they sit properly in their groove.
