harvest Posted March 28, 2020 Share Posted March 28, 2020 i have a 10 bolt rear differential showing a tag that reads 43/14. i got this rear from a lady friend who's husband past and was a 1950's- 1960's lincoln and cadillac car collector. Would this rear axle possibly be from a cadillac or lincoln. im thinking about this to be from a 1957 lincoln? what does the 43/14 tag stand for? thank you for any knowledge that can be shared.

JACK M Posted March 28, 2020 Share Posted March 28, 2020 3.07 gears? 43 divided by 14. 2 Link to comment Share on other sites More sharing options...
Marty Roth Posted March 28, 2020 Share Posted March 28, 2020 Jack is correct the two numbers represent the number of teeth on the gears : 14 teeth on the Pinion (smaller) Gear, driving the Ring Gear and turning in the same direction as the Drive shaft and typically the engine and transmission 43 teeth on the Ring (larger) Gear, driven by the pinion gear and turning in the same direction as the axle Simple math tells us 43/14 = 3.0714285, or more simply stated, a 3.07 ratio differential, so assuming a 1:1 ratio from the engine through the transmission, and no overdrive ratio in use, the engine turns 3.07 times for every turn of the rear wheel(s) 1 Link to comment Share on other sites More sharing options...
Marty Roth Posted March 28, 2020 Share Posted March 28, 2020 (edited) Harvest, The 1957 Cadillac Series 62 used the 3.07:1 Ratio, but the 60 and 75 Series used a 3.36:1 Ratio, at least as a standard ratio, per the Classic Car Data Base. A 1957 Lincoln Capri Series (as well as the Premier and Continental Series) could indeed have had a 3.07:1 Differential Ratio, as per this link: http://classiccardatabase.com/specs.php?series=5350&year=1957&model=27122 Bookmark this page 1957 Lincoln Capri Series Know your VIN?
