Daves1940Buick56S Posted May 27, 2015 Share Posted May 27, 2015 Currently installed is a 3.36 pumpkin from 1954, but the ring/pinion are worn and it howls like a banshee. Just need the ring and pinion as the carrier gears are good and the carrier bearings are new. Want either 3.36 or 3.6 to keep revs down on my engine.

old-tank Posted May 27, 2015 Share Posted May 27, 2015 3.36 would be late 55...54 and early 55 used 3.41...and 55 had a lot of one year only parts: case, rear pinion bearing, etcBest to change the whole pumpkin again to be sure parts are compatible....just swap driveshaft.Willie Link to comment Share on other sites More sharing options...
Daves1940Buick56S Posted May 27, 2015 Author Share Posted May 27, 2015 OK looks like I have a 3.41. I know it's from '54. So I know from there back it should be OK, so I need a 3.41 or 3.6, and would consider 3.9 but that's the max. And if someone had the whole pumpkin that would work as well.

Daves1940Buick56S Posted June 18, 2015 Author Share Posted June 18, 2015 Skip: I did get a 3.9 off Ebay and it looks good but will check it out closer next week. If it looks bad I will give you a call. Thanks, Dave Link to comment Share on other sites More sharing options...
