How I will build my own oil cooler for my TE511

No, bad idea, please don't think that. Drive the centers out at least while the JB is still semi soft and seal with new JB.

The two inner most rivets are getting grinded down to a certain point. You being in the aircraft industry I will deffinantly take your advise. To late to drive the rivets out, bedtime.

I would think driving the centers out would weeken them ? I drove them out a little to coat them before using them so they are internally sealed.

They don't add any strength, they are only there to form the buck-tail and those rivits don't have lock collars on the stems.

When's test time?

As soon as I do your breather mod and refill Rads . I might skip the breather mod and just fill rads lol

I don't think the rivets are under any stress at all. The JB alone is holding with 6,000+ lbs of strength . I think the clutch cover will break before the fitting breaks off if anything the rivets helped the JB form a great bond. I will shave the rivets A little .

That is one sexy clutch cover, you got there
Hey, on the bright side, if it doesn't work, now you have a custom oil return for your oil breather...

Or maybe a clutch plate inspection hole haha

should i grind down the last one ?

Poll : " Like " If you think it will pump oil

"Like" if you don't

Just spent $40 on a craftsman step bit , ouch ! Should of just bought one from you. Oh well it will last a long time and come in handy with my projects .

Lol, no more grinding, you need the heads and tails for them to function. Vibration and heat cycles are what Im concerned with. Give it a shot but don't get too far from home or the truck and get them out ASAP when your done.

I might be a bit clueless but why not take a good solid piece of round stock, thread it, thread the hole in your cover, and thread it into the hole with some red loctite. Then, drill out the round stock and tap it for whatever barb fitting you're going to use.

The inner two I had to grind so they will clear the basket, I will leave the other alone . The two I grinded are in a low stress area the JB has a really good hold on the fitting. When you tap it sounds like the mod was poured with the original mold.

The cover is too thin. I would have .

I think you are doing it the best you can for a test.
I don't know how you will be able to tell if or how much flow you get through the cooler tubes? Do you have base oil temperatures for given ambient temps on a particular hill climb or hard ride with out the cooler? Or oil temps compared to coolant temps? Just wondering.

I will hook a clear tube to the hose barb and run it to the roof of my house to see what kind of pressure it puts out I will figure out a way to transfer the heat out of the oil after a pressure and flow test. Maybe pump the oil into the swing arm or frame .

Who really wants to know ? Ty ? hee hee
