Stock Differential

[markm]

Anyone have an idea what a stock 3.36 open third member weighs, just the jug. I have a guy who wants to buy one.

I have never weighed one but had mine out to re-seal it a few years back I'd guess about half of what a Muncie 4 speed weighs or less. Maybe 35 to 50 lbs. range, just a guess though. I could be way off.

bathroom scales will give you a close approximation.. .. ie. take the scale to the garage, rather than the diff to the bathroom..

Are you speaking from experience lol.....

Of course... but only with wheels.. not juice-dripping differentials..

I'm of the belief that the later design ('61? and later thru '64) are of a heavier construction, and thus should weigh more if that's true... Did you have weights for both the original design and the update design?

Aren't the thicker gears 1957-on? with 55-56 thiner lighter?

Rocky, I was speaking of the differential chunk *housing* castings, and I'm totally not sure there was a change in the Posi chunk housing casting number... or not?? I've been trying to figure that out as I have a '61 dated and '63 dated '812' P-casting posi carriers...

My understanding of the thicker vs thinner gears has to do with the ratio...

I weigh just about everything I ship with a bathroom scale. I've even weighed complete frames and clips on pallets. Seem simple to me, if you own a high tech piece of equipment like that.
