Disassembling a Regular engine

My son and I have been pickibg at a 1928 regular for several months now. Near term goal is to strip the block and get it boiled out before reassembly. It"s been a battle for sure with stuck lifters, stuck pistons, yada yada.

We are down to the crank, rods are loose, pistons still in sleeves. Cam in place also not being cooperative but moves a bit.

Shrt question is which way does the crank come out of the block? To the front or the rear?

What documentation we have suggests to the rear but the reproduction process leaves a bit to the imagination. The plates on the front and back of the block that hold the outer races are unbolted but nothing moves axially and there seems not to be a way to jack anything out.

Any suggestions from anyone?

The crank has to pulled from the rear. You either have to carfully rap on the crank with a large hammer to drive it out. Than once its loose carefully pull the crank out the back of the block. At least thats how I got mine out.

Thanks. That was about wher I was except for the tapping with a hammer. I don't like doing that where ball bearings are involved, they don't tolerate shock loading well and these I think are radial bearings.

I might try to push it out by modifying a gear puller to bolt into the block. I just wasn't certain which way to push.

Thanks again

This is the easiest way I've found to remove flywheel is pictured. Wasn't sure if you got this far or not. Then I take an appropriate punch and slowly knock out the front retaining ring around the main bearing and the crank comes our rather easily. Keep us informed.
