| The
ARB Air Locker is an air operated, driver controlled differential
lock activated by pushing a dash mounted button.
When the dash
mounted button is pushed, compressed air, delivered by the ARB 12
volt, on board air compressor is passed via a 12 volt solenoid
down an air line into the differential housing. The air travels
into the differential center via a specially designed seal housing
which seals against an extended bearing spigot.
Via air
galleries, the compressed air enters the piston chamber and
actuates the piston and clutch gear, moving the gear into the
locked position. The clutch gear now locks the side gear to the
differential housing instantly stopping any differential action.
The diff is now 100% locked, and both axles will deliver 100%
traction.
To disengage the
differential the dash mounted switch is again pushed, which
releases the compressed air via the solenoid and the piston
springs return the piston to its original position. The
differential is then fully open allowing full, standard
differential action.
The ARB Air
Locker only takes a split second to engage, making it the only,
truly, driver controlled, differential locking system.
