So what changed.? Same exact type of bearing? Lubricant properties? When installing the bearing was manufacturing procedure? What is the HP and Torque rating of the beating? What is the RPM rating of the bearing. Are all above identical as the original bearing.

I recommend take it to a balancing company. To verify max out of balance, then take advice from them for the next step then decide.

I would set small short goals. That I knew I could accomplish.. don't set goals that are not achievable. I had many many set backs. I made mistakes But that's how we learn. Most entrepreneurs fail many times , but they learn from their mistakes And keep trying till they succeeded. There is an...

Here is extensive white paper on the matter

a little back ground and my challenges when i was a out of high school, I went to Jr College I had no idea what I was going to work. my high school counselors said that I was destined to be a construction worker. so no real guidance. I was so ill prepared out high school I had take all the...

I not sure I follow your explanation. To my experience with gear design, the object is to obtain material with the correct tensile properties. starting with the y or with a safety factor. Interpolate the the number of cycles required to sustain the number of cycles. With torque and rpm vs...

I never have been involved with balancing of electric motor.but did with aerospace gear shafts. Dynamic 2 plane balancing. The machines used not that complex. But it was permissible remove material with a hand grinder. I had a 383 stroker Chevy engine. The crank shaft was from ac400 Cid Chevy...

Well that's a good point , however looking at the pictures , looked deep to me but looks could be deceiving. The welds visually look terrible. OP Can a fitter take spot Scotch bright. And or light sanding. Take before and after picture.

First question Was there passivation, and proper packaging , vacuum sealed Or similar. Second question Was there any heat treat involved as Ed stainless any post weld heat treat has to be low as possible. Any solution anneal , and any fabrication, post NDT Is done to verify no intergrannual...

Additionally just add to Ed's comment. It also depends on the geometry of the component. And how it is manufactured.

Well I am restate my comment. While I am not a QE engineer I do have experience. I belive it depends on the level of quality and manufacturing systems and procedures for the application. What degree of quality and records retention. Certification of the personnel and processes. What type...

google the effects of stress corrosion cracking and the effects on steel. depending on the application , stress loads and moments. stress risers with pitting then crack propagates.

The operator over bends just slightly to mitigate spring back, it depends as Ed said tensile strength or equivalent hardness. .it has to be developed to obtain correct dimensions.

Here is an example of a typical ASTM spec Recommended stock removal ro remove imperfections. Size needs to be adjusted To allow for stock and to meet print thickness

Really not my specialty , but why are you trying To calculate with corrosion. Object is mitigate corrosion with zinc anodes, coatings or plating, or paint. Low carbon steels will corode in a short Period if not coated with some type of oil preservation. All components I have dealt with that...

OP Please provide the material spec

How would that be setup? Program?

Wow practice in theory vs actually. I believe they are pushing more for automation. Cnc controlled cmm

Well wait and see. What the investigation determines. But it could be minor or major otherwise why open an investigation. And why recall.

Well it depends on the level of experience of engineers and the support group. Which I am surprised Honda is having issues. Data or science is only as good as its sound Accurate data collected. Here's what we know , there is a recall, so there's an issue. We don't have enough information until...
