Does anyone know the diameter of the rear cam journal on the V8 Packard engine?

I'll measure one tomorrow.

1.435 inch. Measured with a micrometer.
Have u found a replacement part number/manufacturer for the cam bearings????

Cam Bearing set numbers, both NLA:
TRW #SH293S
Federal Mogul 1147M.

The cam bearings I've bought lately coming out of Kanter, Egge, Terrill, et al are shrink-wrapped-white-box-made-in-Taiwan, as are their rod bearings. Anyone have a source for made-in-USA rod bearings, cam bearings, pin bushings?

FWIW, for many years, Kanter has listed in their catalog and on their website, "5.1401 Piston pin, standard or oversize .003",.005", .010", each $8.80"
I tried to order three sets last month. The phone order taker called back to say they don't have them and aren't sure they ever had them. I then talked to a parts guy who has been there forever, "You're obviously the first one in all these years ever to try to order oversized piston pins, or we'd have taken it off." Kanter STILL has the listing on the website.

thnx, jack vines

For wristpin bushings, you might try FM #2304, not identical but should substitute w/o problems.

Thank you very much, PackardV8, Jack, and Owen for your replies. I was at a tag sale over the weekend, and there was a collection of auto engine small parts, unknown make. It included a rather small diameter cam bearing, which I thought might be for a Packard V8, I remember seeing the rear cam journal is smaller than the others. Turns out it wasnt for a Packard V8, wrong size. Thanks for the measurement, PackardV8.

Both Studebaker and AMC used small-diameter rear cam journals. In fact, the AMC V8 cam is easily mistaken for a Packard, just an inch or two shorter.

thnx, jack vines

Jack and Owen. How do guys burnish the wrist pin bushings??

Packpower. How far off was the bushing size u found at the tag sale????? If it was only .003" larger then it just mite be the bearing because they will usuualy compress a little when pulled into place.

If i remeber rite, Kanter advertises OVERsized (NOT undersized) rod and main bearings. What's that all about??? Maybe a misprint???
