  • 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 The previous version was outdated and no longer supported.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!

TE310R 2013 Oil Filter ?

ps the other screen is a pre pump filter bathed in return oil at the bottom of the crankcase.

Bathed in return oil at the bottom of the crankcase,,
By this I assume you mean return oil from the return hose connected to the drain plug on the 310's?

If you remove the drain hose does this screen do anything? I noticed the 250 also has this screen.... To me it seems to be useless unless return oil comes from inside the screen through the cases so the filter does something....
 
You have to leave the oil pump prefilter screen. I have a secondary plug which replaces the hose barb and allows you to keep your filtering.

engine "return" oil is gravity into the crankcase outside the lower screen, that silly breather return hose feeds directly into the "clean" oil pump side of the lower filter screen.
Remember the original x lite design TC 250 does not have a closed loop crankcase breather set up and uses a an oil drain plug.
On my 2011 TE310 I have eliminated the oil lower drain back line and have the upper frame vent going to a crankcase breather filter to atmosphere with a plug at the intake boot the lower frame return line spot is plugged but the middle still goes to valve cover. And it has a TC oil drain plug.
This crankcase breather stuff is an "EPA" mod and probably and afterthought as well when they found that crankcase pressure was pushing oil out .
On my 2013 I only have the upper frame vent to atmosphere. I left athe other 2 lines as they were.
I hate that lower hose because its far from a bullet proof any leak or issue down low and you lose all your freakin oil. At various inspections Ive all ready found it loose and weeping oil and yes I have punctured the oil line with an over length screw for my skid plate, even after ID ing this issue, I some how missed it on post install inspection.

I assume that engineering figured that the breather return oil was from mostly vapor with some liquid oil blown up from the valve cover so it was ok to re intro it directly into the pump feed......also Im sure they wanted it under the oil bath to minimize crankcase pressure pulses while trying to get it back into the crankcase. My 310R set does this but my 310 blackhead depends on the frame to dump the oil back in from the valve cover vent, after theoretically filling the lower portion of the frame with liquid oil. Not the greatest set up but less likely to have oil loss from a loose or punctured vent return hose.
 
Utilizing our new kit will eliminate the danger of running your oil return line to the bottom of your case. Add a little convenience during maintenance intervals too.
 
Sweet thanks for clearing that up :)

So a drain plug with a magnet would be beneficial, it will pickup anything that happens to get through the screen before the oil pump.

Thanks guys

Not sure about that just yet. Tinken seems to think a magnet back there would be bad if my memory serves me right. A magnet would be beneficial if possible IMO
 
I hope to see the drain back kit on a bike. Im a bit confused by some things I've read.

All I know is that I saw some watery looking oil drain out of the hose when I lasted popped it off to change oil. That kinda freaked me out. It may have just been condensation forming from cold weather and short running periods. Or I hope it is.
 
I really like the idea of the drain back kit, will def make oil changes easier and looks sweet.. Only thing is I get a little milky oil in the existing line going to oil drain plug that seems to stay in the breather line. Will kit mix this in with oil a little more since it dumps it in on top?
 
Tinken, there is no clamp on the return line to your fitting. I did use one but the space is very tight and if it isn't needed I'll disappear it. There sure shouldn't be much pressure at that point.
