And the expo thing to do is put a bottle opener on it. Come on now, keep up!
Are you pulling your transfer box that often?

The expo thing to do would be to make it out of titanium.

And sell it on the snow peak site. Titanium smelted with unicorn tears.


In fear of completely derailing Lav's work, I think adding more oil capacity to the T Case is a good idea. I still would over fill it, but it would take longer for it all to leak out.

No concerns of the level being to high and foaming as w/ motor oil?

I believe you've confused cooling fins with speed holes.

Speed holes will help you go faster. Unless you are referring to cool stickers that increase HP (which can be related to speed increase).

Ahh, you are correct. I meant they would keep it straighter at higher speeds.


But forreal Lav, what would the price point be? Ever since I saw the global roamer one on Brandon's truck I've wanted one

Makes me wonder what a used oil analysis would report after 30,000 miles.

I don't always pull my t case, but when I do, I prefer my bottom flat.

Keep your 90W full my friend

On a transfer case? Shouldn't report anything. Really, unless you seriously overheated the oil, it would last basically forever. There is no reason for it to break down.

There seems to be a concern with overheating. Not sure where it comes from? High power, high speed?

There also may be some confusion. Jason seemed to believe people overfilled to get more oil in the sump. People overfill to get a higher level that they think will help lubricate the input gear splines, not to get more oil.

The Roverdrive sump was designed to remove heat as they found the overdrive heated the oil during extended high speed driving

The super duper Lav model looks to be cut out of billet aluminum, so it may take a jack, but to be completely safe you would need steel construction.
The beauty of being cut from a billet is no leaking inside out.

The other units I've seen are cast, which means porosity from trapped gasses prone to leaking and much weaker overall as well.
If not heat treated, the castings can warp and shrink as well.

You can also stencil "Turbo" on it with the same results.

The unfortunate reality of leaking from the sump cover on the LT230 is that some genius designed the sump cover bolt holes to be drilled clear through into the gearbox case.

You can put as much goop around the sump cover you want, but oil will always leak around the threads. I suppose self-sealing gaskets at the head of the bolts would help.

The standard sump cover on the LT230 is very well made. Nothing wrong with cast aluminum. Nothing.

The real advantage of an aftermarket cover is the ability to mount a temp gauge.

You mean something like this ?

NOTE: this would be an "option", and a blank version would be available for those that don't want the port.

That is what I'm working on now, it's a large block of material to start with (i.e. lots of waste)...and quantity is the key (which I'm working through now). Whereas with some of the other items, I don't foresee doing 'hundreds' of these as it's more of a specialty item/one-off kind of thing (i.e. probably won't appeal to the masses, but certainly will have some niche interest). I'll keep you posted once I put some hard numbers on it.

It certainly looks beautifully done, and I'm tempted to want it just for that reason..

We manufacture oil pans and have had castings leak.
The true fix is sending them to a place to go through a vacuum resin seal process where the porosity is filled to stop the oil leaks.

To seal the bolts, Lav could have an O-ring groove machined into the fancy T-case sump and use a flange bolt with O-ring to get a full seal.
It could also be done via a groove on the bolt side which is more difficult, but easier to sustain.
