Flooded Transfer Case Questions

I have been searching for a new transfer case for my jeep and have finally come across one that seems to be working. Transfer case is in a vehicle that was flooded and has sat for about a year since. It shifts alright, maybe a little stiff. I plan to drop the oil out of it this afternoon. What should I look for ? Also if the oil is not clean looking, can you replace the oil run it for a few days and change the fluid etc until it looks alright, or should I keep looking. I just don't have access to very many parts here, but would prefer to not have to wait for a recon, transfer case to get here if possible.

I would just look for water inside. If a bunch of purple milkshake crap or a blast of rusty water comes out, then I would think twice about that case.

You don't say what kind of TC, but I sure wouldn't want a chain driven one that was water soaked for a year.

I agree its a np 231 21 spline transfer case, and I just wanted to know if there were any particular things I should look for.

Thanks

You could be lucky.

Unlike the 'unvented' (no high water line) transmission, the t-case has a vent line with a waterproof valve on it that should keep water out if the Jeep remained right side up and wasn't submersed too awful long.

Not on the outside. Spend a few minites and open it up. Any rust means all bearings are shot.

So even if the oil looks alright, I should open the case up and look for any rust that may have started on the inside. If any rust has started I should continue looking correct ?

Water is obvious when you open the drain. If the oil is clean, no worries.

Oil looks slightly off color, not milky or dirty, just kinda off color.. I'm going to pull it off and take a better look at it and have a few mechanic friends give me their opinion.

Water is really obvious. Your descriptions sounds good. Water falls to the bottom so a clear stream will come out if the t-case was filled or got any in. If it gets mixed in too, the oil goes like a milkshake consistency.
