Align-Reamed Bearings
Model T engine with align-reamer in place
to finish main bearings.
The align-reamed process is the method I use when finishing the main bearings of Model T or A engines with poured babbitt bearings. The process involves the pouring of the babbitt, align-boring the babbitt, and finally align-reamed and roller burnished for final fit and finish. When completed, the crank shaft has a clearance of one and one half thousandths
(.0015”) of an inch and is easily rotated with one hand. No other method assures such perfect alignment of the three main bearings. As is seen in the photo above, the align-reamer is first piloted in the align-bored bearings and then does its work, removing only .005” of material from bearing. Align-reamers are manufactured in my tool and cutter grinding shop.
