Identifying bearings

[Rick Kirchner]

I'm rebuilding my motor and trying to identify the bearing specs. What came out has the following markings:
ACL
5221
OC11
.25

From a previous re-build I have some with these markings:
23AU05
ACL
5221
.25

And a box with the label 5M1084P-.25; MS1084P 035M

I can't find these in the hot mess that is the jumble of ACL catalogs. Can't even find a listing for Pintos, although there is one for the YAC.

I get that they are .25 oversize VS std, but how can I tell if there was a line bore involved? And anybody know what the current part number is?

23AU05
ACL
5221
.25

The bearings and their specs are listed under the engine/s Model prefix TL20H, "Pinto" is more of a slang term If you click on each bearing in the link below it gives all dimensions required to select bearings. remember if between sizes you can use one shell half .001" under size and one half STD as an example. They offer .001" extra clearance bearings as well.

Worthwhile to measure the block bearing bore.

I obviously never found that page, but I don't think TL20H has ever been used in any context with this engine that I can remember, NE series maybe, but TL20H (and high compression?) is a new one around here.
