Re: '38 six cyl question

This problem enters the gray area of what constitutes Packard parts? I used to work with a top notch machinist who fitted Dodge bearings to the 320cuin and 384cuin Packard engines. He would weld and mill the rods for correct side clearance in as is the modern practice. The owner would get a box with the part number on it. This work was not cheap. As time goes by even those common bearings will become scarce.

Question one is: Are the bearings in question actual Packard or something else?

Almost everything today is something else. I used to have some of the genuine stuff and the boxes have since turned to dust. Seriously, they fell apart from age.

Question two is: How much information is sufficient?

Well, simply throwing parts at the customer and saying "you figure it out" is not very good. The least that can be included is the correct amount of bearing crush - generally .003 to .006 with a limit of over .008 necessitating machine shop work. This will provide the required 12,000 psi interference fit.

For the Packard Six this is complicated for the guy doing the work himself. And good machine work is getting hard to find in this dumbed down, Junknet, the only skills that matter are verbal skills trash economy of ours.

It's a funny thing that I was wondering this morning why everybody talks about why a BA is not sufficient anymore.
The answer, I think, is that universities have been watering down degrees to keep people there and administrators at inflated salaries paid for by skyrocketing tuition charges.

So anyway, we all need to practice trying not to behave like junknet entrepreneurs and practice providing better information.
