[Kohnke Rebabbitting]

DO NOT shim under the 4 housing bolts, as this will warp a usable housing in the wrong places.

The first thing is you have to have a level crank flange, and also a crank that is centered, in the babbitt, between the main, bolt holes. with out it your wasting your time. If that is off, your housing will be also. It is flange, to housing is what your trying to level. So if your crank is left or right by .010, The pilot shaft will be off, out of alignment, also.

Many Guys think you have to have some kind of level flywheel housing. I have never had one I couldn't level, no big deal. We have built in access, of 350 A engines, and many more then that, in babbitt jobs, where the customer also wanted us to install the flywheel housing.

You have to do two steps, to get a level, 4 point contact, to bolt the bell housing to.

First, get 9:00, and 3:00 to read the same, just the sides, first. Coarse adjustment, will not work. You have to have Brass, shim stock in, .001, and .002 thousandths, when you need it.

Movement for the side adjust, is set by shims put under the two top bolts, From side to side, chances are, your shim packs, will be different thicknesses, and 9 & 3 should be with in 1, to 2 thousandths.

When that is done, now you do the top, and bottom, 12, and 6, the only thing that is important here is that they both are, the same. This movement here, up or down, what ever you put in, or take out, they have to be equal, both sides.

They may, or may not be close to the sides, but what you want is that the bell housing will be square, with the flywheel housing, and engine.

We always let the first adjustment set for 24 hours for warping, and also the 12, and 6 setting.
