no noises from tcase. just the normal noises from the f/r diffs. locker type bs.


it is for sure hot. vaporizing water hot. car wash cooled it to the point of light going out.
I just have to figure out why its getting hot.

 

I was following an H1 forum for a while and they used to have problems with there T-Cases getting warm after going over 65mph for extended periods of time. Now, I'm not sure what caused them to do that exactly. I assume is was that the H1 was built for low gearing and torque and not the Indy 500.

I know that you do have a lot of upgrades like new gears, TT lockers, bigger tires, HD drive shaft (not sure on that one but knowing you), and many more upgrades. Maybe it's as simple as your upgraded rig isn't up to rolling 80mph anymore. But like you, I am mostly an idiot

 

you maybe right. I have built the perfect parking lot security vehicle.


as you mentioned, I fear there is an issue with a diff. ...this weekend I will start the shaft drop and drive testing. oh, boy. I just made it home, at least. so, no I81230, yet.
on to the solution.....

 

Just curious what are your RPM's at when cruising 80mph with your new gears? The reason I ask is because I've heard of people over 3krpm's at 70mpg with 4.10 gears and if I remember correctly you went even more hard core than the 4.10. Could it be that your engine and drivetrain is running at an rpm that the disco would normally not see unless it was going 100mph with the stock gearing? That would cause things to heat up a bit if it's the case.

 

Dusty,

Overfilling your transfer case or anything else is bad, i hear a lot of people doing it.

Most time if you overfill something with gears, they tend to cavitate and mix air into the oil. eventually you will end up making foam rather than pumping or splashing gear lube around.

JMHO

 

Gtk. Thanks.

 

x2 it also often over pressurises and blows out the seals as well.

 

How could it change the internal pressure?

 

Froths, creates heat, oil and air expands in an unvented case then leaks out via the least line of resistance, the seals.

 

So Dusty, how'd you come out?
