LSD modified to hydraulic locker... (1 Viewer)

Can't see pics. . .

Can these pics be reloaded as this guy is close enough that I am interested in having a look.....

Sorry
Now they are available again! they were on a temporary server.

I can't sleep anymore ... just thinking all the time how to modify my LSD to get a locker.

After some research i found a hydraulic system ... a spring accumulator/actuator working to both sides - as a replacement for the spring ... BUT I can't imagine how to get the oil/air through all the moving parts/gears ... any idea???

seen the ARB diagrams ( internal function ) I thought if is posible made somtglight like a fluid carrier .. thinking first in one side, to push the mechanist and pressing the discs .. ?

A proper locker works as locking one shaft to the case, so the case can't turn faster than the shaft, so differential can't function. It would be pretty easy to transform a limited slip into a locker then, make another washer/disc behind the clutch pack which has eight or more litle perpendicular rods atached to it , going through holes you've drilled in the diff housing, there's another disc outside not touching the body into which the rods are also affixed, and a last ring with rollers onto it pushing the previous one, which then would push the rods and the inside disc pushing onto the clutch pack locking it. Petty simple to make i'd think! Providing there's enough room between the outside ring and the bearing support. It could be actuated by hydraulic means. There's so many ways, like the one i was talking about, using two locker cogs, one machined so it doesn't have the splines and the grove at the back, welded (or screwed) onto the bearing race, and the normal cog locking it onto the shaft, as the normal difflock works! That could also be hydraulicaly actuated.

Hi Max,

just for my understanding - the way this solution works is to press the gears into the pinion gears to achieve the locking?
Can they stand this load?

Hi Tonito!

I don't get what you're saying! Basicaly the trick is to augment the presure onto the discs pack so it doesn't slip anymore. There's discs which have grooves fiting into the shaft splinesand there's spring rings (bellevile washers) which press onto teh other discs, the friction on the packs makes the locked discs turn, untill the friction is taken over by the speed difference between the two shafts! The washers which are locked onto the shafts have a cross shape!
