Re: 48-54 OD Trans

BDeB posted overall input shaft diameters for the two units. https://packardinfo.com/xoops/html/mod ... id=174654#forumpost174654

The senior or larger input shaft trans is only used with the 356 engine and the end of the shaft that goes into the pilot bearing is just a few thousandths under 1" on that unit. Don't have a definite number handy on the pilot end for the smaller unit but think it is around 3/4 or 7/8. In addition to pilot bearing, the clutch disc and possibly the pressure plate also would need to change to accommodate a different shaft. Throwout bearing and entire carrier assy is also different.

The senior R9 OD will also have 4 planetary pinions in the unit vs 3 for the smaller OD.

Ok, if y'all know what it is that's great. Still a good trans and OD unit.
