fascinating stuff:

I've been watching these too.
Very interesting.
The part about over filling the diff causing more aeration and less lubrication was a surprise.
 
Same can happen to engines,transmissions ,even wheel bearings if you pack too much grease in them..more isn't always better!..
Yeah
Bigger capacity is good but not by over filling.
The oil needs to be below a certain level to prevent the whipping which creates the bubbles.
 
Really good stuff!

Did y'all catch the mention of the AAM 11.5" axle having an optional 11.8" gear set (episode #1) ? I wonder what the application is?
 
add this one .

this is some cool stuff to watch .

and i have always been a g.b fan for the way he builds power and parts .
 
Gale banks said once, we don't want our products to produce black smoke. That's wasted fuel and power, we want to make power.

:bow::bow:
yep i always shake my head at the diesel guys b!tchin about fuel prices per gal yet they dump it down the tail pipe and let it roll out as black smoke .
 
A lot of people with a 203 part-time conversion including myself add nipples and an elbow to fit more oil in. The idea is because less stuff turning not throwing oil into gear box. But now this has me wondering if that's a bad idea.

I always heard that the reason to over fill a part time converted NP203 is that the chain is no longer in motion when in 4Hi.
This prevents oil from reaching the rear output bearing.
Also why you want to lock the hubs and or put it into 4hi loc every 200 miles for a few miles.
Refills the gallery that feeds the rear output bearing.
 
The converted 203 doesn't completely equal the diff cover test because the part time kit changes they way it originally worked / oiled.

I always thought the conversion kits suggested motor oil because the lighter oil would splash / throw easier than thicker gear oil?

Hmm I thought it was the gear box. I've got mine over filled by 4 quarts if I remember right. But maybe I should still lock her up once a week or so.

Getting off topic but i gotta say this;
NEVER put gear oil into an NP203!!!
They require 30 weight.
Period.
That is what they were designed for, what Chevy specified, and the part time kit or not, gear oil will ruin an NP203.
 
Gotcha. I've never owned a (complete) 203, I just figured it used gear oil in stock form.
 
Now does anyone make an aluminum diff cover with stock shape and louvers? Don't think it would be good for off road though.
