personally I bet that they are "forged" powdered metal.

can you explain that one I am not sure what that is?

Daimler Chrysler uses the same crap for its connecting rods in the 4.7 and 3.7 engines.

Its a metal substance (the compound varies) thats literally powdred metal just like a fine dust to a fine sand dependiing on the courseness called for. They pour the powder into a mold and compress it with a lot of heat. The powdered metal melts and then takes the shape of the mold so technically its forged as they used pressure.

Not enough heat and the inner metal does not melt bond to each other well and you get a weak part.

[fabr]

Well they're not exactly weak as such   but they have zero ductility.LOTS of stuff is done with PM now in automotive and many other applications.

ok I didn't get down to take a few pics today but tomorrow I will, ya I'm taking a lazy day hell I took a lazy week my knees needed it after installing a new wood floor in the kitchen and dining room for the wife. I can now check that one off my list and I should be good for the winter! ya right!

any way I may have been the culprit behind the failure on that yoke. I had a dust cap fall off so I went and bought a freeze plug and popped it in but first drilled a hole in it. I also jb welded it place. after two days of riding around my place I saw the jb weld was flaking off so I pulled the axle and welded the four corners. not huge welds just about 1/8". it really does look like the brake started on one of those spots. it broke at the transaxle on the drivers side. when I clearenced the yoke for more angle in the beginning I went a little too far on one side and saw a small hole so when I spot welded the 4 corners I filled in the hole ( in the middle of the yoke ) and buffed it back. that was before I went to LS to meet up with everyone in the rain and cold. it lasted for that trip and two runs out in the field before it failed and of course I was coming off the ground hitting the terrace's and landing 3/4 throttle never letting off the gas. after a dozen or so runs like this it failed. but there is a spot along the brake on the lip tube itself that looks like a bad spot in what ever process they used to make it. this is what I want to post a pic of. I will get it tomorrow.

You mean sintered metal? Like Oilite bearings? I think that's what you mean, anyway.

[fabr]

same technology but different compounds and similar processes

[chrishallett83]

Ah, because there are very high performance engines getting around with titanium conrods made like that.

Can I guess yet PLEASE!!!!!!

[dsrace]

go for it!

[Doug Heim]

3000 RPM?

[Dunebound69]

You where sliding it sideways. Then you gunned up the terraced hill witch led to a loss of traction over one of the terrace's. You then naturally stayed in the throttle and when the rear wheels came back down. KABOM any you threw dirt and grass at me big time


Where the hell was my in car camera. Oh yeah it was in the liquor cabinet!

[SPEC]

Funny how the truth changes between points of veiw

[Carlriddle]

Now we have gotten the bottom of this, Liquor Cabinet+buggy=broke.

3000 RPM?

good guess actually 6450 rpm, I hit the rev limiter when it came down! lol
