packard v8,

The arbor had 4 set screws in the inserts machined to the shoulders on each end of the tranny. This allowed adjustment of the ends to get the transmission concentric with the arbor. The 700 r4 bell housing was ruff cut with a porta-band saw. Then machined to length before welding on the 1 " plate. The amount of warping surprised me (.115"). After the unit cooled it was placed back in the lathe and the center cutout to correct size. then the outer diameter and the front face clean up to square. A shoulder 3/8 "deep at an OD of 15.312"dia was cut next. This should center the transmission shaft with the crankshaft center if it is concentric with the bellhousing openning. I've made a bushing to correct the size difference between the packard (1.85"pilot hole in crankshaft) and the button (1.699") on the 700 r4 torque convertor. The bolting of the convertor to the pressure plate is not complete yet. Once the Tranny is reassembled I will see if the convertor goes in the bushing correctly and if I have the 3/16" travel or movement between the flywheel and the bolt pads on the convertor. Still a work in progress.
