Why locking the differentials?

[kc092755]

I read the sticky article "TLT-1 to TLT crawler",
it mentions "....locking the diffs with JB weld.....",
may I ask why locking the differentials gear?
what would happen if I don't?

I also read somewhere else, mentions locking the center differential with two screws,
why?
thanx!

i know you are a noob, so i will be nice. when you lock the axle diff's you transmit more of the motor power to the tires. when you lock the center diff you transmit equal power to the front and rear diffs. basically you can go more places.

Hi chafey, thanx for your reply.
I'm not sure I understand, so if I don't lock them they would transmit less or unequel power because of slippery or what?
In order to lock the center diff, I need to take 2 metal balls out or take all the metal balls out? does the differential still in function?
thanx!

in a nutshell...

open diffs = 1 tire in the front and rear spinning
Locked diffs = all 4 tires spinning

if you don't lock your diffs, in a situation like this the tire not on the ground will get the most power.




there are many ways to lock the diffs. The easiest way for me was to just fill the diff with hot glue and put everything back together.

Thank you all for the replies.
Is this mean just make the diffs not working (either center diff and axle diffs)?
Thanx!

Not a good way to put it, but yes. With locked axle diffs, all the torque from the transmission is transmitted equally to both wheels on the axle at all times.

If left "open", the wheel with the most resistance would slow or stop while the wheel with the lower load would receive all the power from the tranny. So the wheel you would need to pull you up or over an obstacle would be powerless.

Thank you Zod Rhombus.

There are no balls in the ball differential pully if I want to lock the center diff by using two screws, right?
Thanx!
