See post #46: These inserts, designed specifically for the Model A, are supplied by Antique Engine Rebuilding (AER), Skokie, IL. They have worked very well for me.

If you look close, you will see the Plastigage marking on one half of the shell. The initial clearance was between .0015" and .00175" before honing. Between .002" and .0022" when honed to proper clearance.

hardtimes: I used two piece (two wide set with a radial oil ring between them) Clevite & Fed Mog bearings on about 16 engines but have not done so for the last 5 years. The supply for these bearings was getting difficult to find readily. They were constantly being backordered when I would order multiple sets. The two piece inserts worked good also. They were tri-laminated. Babbitt over copper on steel. I have two piece Fed Mog inserts in my Phaeton and have had no issues after 90,000 miles.
Good Day!
