Does anyone know where to have parts x-rayed?......having trouble finding a place.

 

What for? what does this do?

 

shows internal cracks/fatigue that maging doesnt show...........
especially in cranks, and rods w/ 220k on them.

 

werd!

 

i think i have a radiologist in the family....hmmm

 

i think the process you are talking about is magnafluxing (i think).

yes

 

magnafluxing only shows surface cracks! im talking about an actual xray, just like you would have done in the hospital. only problem is, there arent too many machine shops that still do this....partly because it is usually cheaper to buy new parts instead of xraying for cracks in old parts.

i was hoping to hear from some of the pros, or someone from a machine shop that would know where to have this done.

i just had a crankshaft break at the end of the season do to an exsisting crack that was inside the metal, caused by fatigue from high mileage. the crank had over 100k on it.i have another crank that i was planning on using, but this one has 220k on it!not going to put that in my new motor w/o xraying it first.other option is to buy a new crank from honda, my cost 550., or try to find a crank w/ low mileage, but id still be concerned about that.

Usually the only cranks I have seen cracked are ones that have been ground undersize, thus taking off the OEM heat treating. I've seen the oem crank make as much as 900 without having problems.

 

had a machine shop look at it...........crank broke between 4th rod journal, and 5th main journal. the break had two different colors in the metal, the inside was dark grey and the outside was shiny and new looking. dark area in the center was existing crack, shiny area around outside was where it finally broke. it happened coming out of the burnout, car fell on its face and stalled once the tires hooked. motor makes alot of tq. , about 200 @ the wheels. im sure if the crank wasnt already cracked, this wouldnt be anywhere near enough power to cause this failure.

 

is this a prelude b20 crank?

h23 crank

 

i was told it is a forged crank. im not sure how to tell? i know any cracks will show on an x-ray.

 

Problem with X-ray is that it's very expensive to do on top of getting X-rayed you need to have an expert look at the results so you can see what your looking at.

By the time you get it X-rayed data exmained etc. it may be more cost effective by another crank
