  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

dry sump engines

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.
 
Thanks for that guys. half the fun of having a bike is learning how it works...well maybe not half...but it's fun nontheless!
