Differential lock inop

[Unilevers]

power dividers or inter axle locks put power out of one diff into another diff - both differentials still function as normal just that 2 of the pinions have input power now instead of just one. You can still get stuck if its tilted as only one side of now both front and rears diffs will transmit power.

Differential locks or Lockers Lock the axle shafts on one differential assembly together. It removes the "Differential" part of a diff and both sides transmit power 50%. They are physical splined collars that fit into the end gears of the diff and the splines of the axle to lock them together. If you shift these in while the diff is being a Differential then it all goes bad.

Now if you have a inter axle and a diff lock you can force power to both diff's and lock both sides of each diff to drive 50%.

Now up here in the oilfield alot of our units are tri drives and they have inter axles and diff locks. So the front 2 diffs have power dividers and all 3 diffs have Lockers. Ever been stuck because you can go only forward and back and cant turn? thats what happens when everything is all locked up on a tri drive.

ever wonder why the power divider always breaks first on a tri drive? It takes 50% of the power input while the other 2 diffs get 25% food for thought!
