2010 HUSABERG 390 Clutch Slave cylinder piston seal

Old School · November 16th, 2020, 06:05 AM

Good day guys:
Husaberg 390 loosing mineral oil into engine after it sits for a week or more, I'm sure it will get worse in time.
Does anyone have a part number for the seal on the oem slave cylinder ?
or a recommended fix besides replacing the complete slave cylinder?

thanks

An O ring does not seal and Ktm does not sell it separately.
It is better to buy a Viton X ring at a bearing shop in your country
The x ring does seal well
for the size see link

I believe this is the O-ring w/ part numbers.

And here’s a thread on it. My seal went out in February and replaced it with the KTM part from RMATV. Working fine and even have spares. Might want to order a gasket while yer at it.
