I've began tearing into my KTA and was wondering if anyone has the specs for the Crankpins and Journals?(diameter, clearances)I am without a manual as they are pretty hard to find. Any help would be great. Thanks.

From 1960 Federal Mogul engine bearing catalog:

rod-2.3725-2.3730 oil clearance .001-.0035 p/n 9780B

Main:
#1-2.497-2.4975 oil clearance .015-.0040 p/n 9781B
#2-2.5590-2.5595 " p/n 9782B
#3-2.6220-2.6225 "
p/n 9783B

Note: mains now are sold in sets under a different part number. part numbers may or may not be available.

These bearings also fit very early Us. The Later Us with KEF, 283 engines used different bearings with larger overall diameters.
I do not know when the change was made.
