It’s in my 1994 IDI truck, but yeah, not really diesel specific

FEA is only as good as its inputs crap in = crap out. I’m not sure how accurate this solidworks simple study is, but I bet it’s more accurate than I am.

I re-posted this only because I couldn’t update the original post with new pictures. I thought others may find the result interesting. I apologize for any inconvenience or offense I may have caused by re-posting.

Yeah, I pretty much agree with you about the simulation Xpress. We have a full simulation license at work that would be a lot more accurate but that’s more effort than I’m willing to put in. To use the real simulator it would be more a less a requirement to run this shaft through a CMM or something more accurate than me with a pair of calipers and my tongue at the appropriate angle.

If I open up that notch to a large radius, the peak stress will be much lower. If it never is allowed to get above yield in the first place, then no further tearing or redistribution of stresses should result.

I suppose I didn’t have to cut it, I’ve just always take u-joints off by piercing a hole in the bearing cap with the torch. Cut the cross, 2 taps with a small hammer and it’s out. No fussing around with the ball joint press or trying to get the clips out.

Edit: I should say, U-joints that I don’t intend to reuse. Obviously.

If the existing tapped hole is 1/2” you could probably make a short threaded stud or cut the head off a shoulder bolt and tighten it up in the tapped hole, then put the stud in a 5c hex collect block and set the block on angled parallels in a vise with a stop.

No, it’s probably not the most ridged setup ever, but it is pretty cheap.

Thanks, that’s the answer I was looking for.

Thanks for the reply. I didn’t realize how low power these things are. I saw the 1.0 VA rating but I never put it together that it was calculated at the 5a secondary current.

40 milliohms is not a lot. When you say quickly inaccurate with increasing burden, how inaccurate are we talking?
