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 The previous version was outdated and no longer supported.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

How I will build my own oil cooler for my TE511

Don't get me wrong, I'm not saying that you're wrong. Just pointing out that a funnel shaped collection point will collect more fluid, and like a water monitor will also help increase flow pressure. Perhaps not by much, but perhaps not much might be what it takes to get it from "kind of working" to "fully successful." It would certainly be a bit more involved in terms of fabrication. Again I like your concept and I'm interested to see how it goes. :)

Thanks for the comments. This idea is new to the moto world I guess. Using the clutch as a cyntrifical pump that is. Cyntrifical pumps have been around in agriculture and oil fields for a hundred years and have the highest flow rates of them all :)

If it pushes oil out the hole to me it is :). The radiator pump is. Yeah it was a figure of speech . What turned you to the dark side lol

Not dark, still with ya, just have a baaaaad feeling on this adventure, hate to see you wipe out a nice top end from starvation.

I hear ya, unless I bust the Oil tube on the clutch housing or spring a leak somewhere on the cooler side the top end won't run out of oil . If it don't work out then I will just fill the hole and anodize the cover red Or powder coat it white :)

I've considered tapping into the external oil line and using an orifice disc on the cooler inlet (so as not to starve the top end) and returning back to the oil filter cavity.

I like this type of arrangement better, but I wouldn't even bother with the office or returning it to the filter. I'd just send it right back where it was headed, to the head. Pump the hot oil out to the cooler and return it to the head. No new taps or fitting, just new oil lines and a cooler.

Plus, you are returning the cool oil right to the hottest spot on the engine, the head. You will get the maximum amount of cooling effect you can get from the cooler.

I have my doubts about Rearwheelin's idea also, but he does have thermo-siphon on his side, also. So it might move some oil. Those crank clutches turn a lot faster than a normal clutch and make a lot of heat. That's why they feed so much oil to them in the first place. It will be interesting to see if it works.
 
My first test will happen within a couple weeks. I will drill a smaller hole where I think the oil pick up should be , insert brass tubing and JB weld in place. Hook some clear tubing to the brass , fire up and watch what happens.
 
I'm not sure how Rearwheelin could starve his top end, could someone please elaborate on this?
Also, I believe a gravity system could work on the 449, but not quite in this fashion, the oil pickup needs to be at the top of the clutch side case as a narrow slot on the opposing end of the oil spin-off. Which way does the crank turn if you are looking at it from the outside?
 
Counter clockwise.

I will be using the same type of oil pick up as my water cooled electric RC boats. My boats were so fast I had to solder the hose barbs and re-drill smaller openings or they would blow the water lines :)

My thinking for not sending the oil through the cooler and to the head was to avoid starving the head for oil at startup. But now that I've said that, I realize that an anti-drainback checkvalve could be put in the cooler inlet side. The point is moot for me though, as after talking with Bill (BMP) I don't need an oil cooler unless I move to somewhere else.

Makes most sense to me.:thumbsup:
It's a cool project, but from what I have learned, to cool fluid or gas, there needs to be a good flow through the radiator, cooler, heat exchanger or what ever you want to call it under pressure.
From what I can tell, it is questionable whether there will be much flow or pressure . :excuseme:
 
Well I can't sleep thinking about poking a hole in the cover :) I have allready thought of 3 different ways I want to make the oil pickup. My newest idea involves a $3.50 brass hose barb and some Blue Magic Quick Steel putty that's rated for 500 degrees .. No welding !
