    Hey all
    Until I bought my TE310 I thought a dry sump was what you found on an engine with no oil (I'm new to bikes).

    Anyway I'm told my bike has a dry sump but I have not noticed an external oil tank. Is the oil storage within the engine casing somewhere? Where abouts?

    Oh something else...what are these 'oil screens' people talk about?:confused:

    Thanks

    don't think dry sump wet sump-

    All oil is in the motor/ tranny. If you take off the clutch cover oil will come out (wet clutch), if you take off the stator cover oil will come out. Check your manual- it shows how to do an oil change and shows all the screens. Oil filter is on right front side of motor held by 3: 8mm bolts. Oil screens are near shifter lever- small allen head, and hex, oil drain under motor case: hex...

    Also, there is a small o ring behind the front 6mm allen head bolt. Very easy to loose in the used oil. Kinda poorly thought out IMHO.

    By definition, dry sump engines have almost all of the oil stored outside of the engine and all of the oil is handled via the oil pumping system to lubricate all moving parts.
    This is done on cars to get the engine to sit lower in the chassis and to avoid windage and starvation problems under High G cornering and acceleration.

    Almost all 4t bikes have wet sump engines, including Huskies- the oil is stored in the crank case.

    I agree with the above info about wet sump engines, but then why does Husqvarna list
    "dry sump" in its spec sheets and other literature?

    Husky "calls" itself dry sump in spec sheets
    I think that is why the OP asked the question. It doesn't matter what you call it, If you only define by external or no external oil reservoir it would seem like a wet sump. But I think the dry sump definition comes more from the oil circuit and pumps than the "tank"- so its not where it comes from but how it travels...:excuseme: at the end of the day least you should know where to expect oil to be and where to put it in and take it out.
