Hot transfer case

[Thisguy]

My transfer case is really hot. Burning hot to the touch. I kind of forgot about it but noticed it again today when i noticed the floor was hot after a long trip.
When I bought the LC I did a fluid change with Amsoil. I have put a lot of miles on it. Any chance the diff lock is stuck? No lights are on. Or is it just the way it is?

You'd know if the diff lock was stuck in turns. Have you checked the fluid level?

 

[Thisguy]

Yes, when I first noticed last year. Maybe even a little over.

 

[Trunk Monkey]

How is it over? If it were over filled it would just drain back out the filler hole.

 

[Thisguy]

I am sorry, that is right. I guess I meant a little came out the last time I checked it.

What is burning hot temperature? Having had the transfer case apart (a work of art IMO)I cant see how the diff lock being engaged would make it over-heat. My guess is you have pump failure or some type of blockage in the oiling system. The transfer-case does not rely on an oil sling only like most, it is pump through.

The case is hot to the touch. Very hot. I did not know there was a pump?

I thought this was typical of the cruiser? There is no cooler for the fluid in it and it will get quite hot.

 

[Trunk Monkey]

Sounds normal. Throw an IR thermometer on it and see.

It a beautiful thing

 

[Thisguy]

What should the operating temp be? Any way to check pump other then tearing apart?

FWIW


Quote from Sleeoffroad:

I hooked my wife's LX470 behind the motorhome and towed it from Denver to Salida. Probably 200 miles or so. Transfercase in neutral, tranny in park, key in lock so wheel is free to move.

I measured the temp on the transfer case with a IR temp gun. When we stopped in Salida, the temps if the transfer case center section, front and rear output areas we all in the 100 F to 110F range. Simmilar to the rear and front diffs. If there was an issue in the tx case, it would have shown up as excessive heat. So for now, I am happy to tow this way.

I would think it being towed would make it cooler?

From the title of the thread I thought someone was onto a stolen t-case...

I agree
I posted the quote as a bench mark
