G80 Operation Description!

I found this on the Weber Chevy Website. Very Good Description!

 

 

Here's the skivy from the General regarding operation.

I hope this clears thing up.

Locking Differential Description and Operation

The locking differential consists of the following components:

Differential Carrier

Locking Differential Spider

2 Clutch Disc Sets

Locking Differential Side Gear

Locking Differential Clutch Disc Guide

Differential Side Gear Shim

Locking Differential Governor

Latching Bracket

Cam Plate

The locking differential allows for normal differential function as

indicated in the standard rear axle description. Additionally, the locking

differential uses multi-disc clutch packs and a speed sensitive engagement mechanism that locks both wheels together if 1 wheel spins excessively during slow vehicle operation. Under light loads, the clutch plates alone tend to lock the axle shafts to the differential case, and therefore, locking each other. This is due primarily to the gear separating the load developed on the right clutch pack. This induced clutch torque capacity resists motion between the side gear and the axle differential case. The differential allows the wheels to turn at different speeds while the axle shafts continue to transmit the driving force. Heavier throttle application will cause an axle speed difference. This action starts the full-lock feature of the unit. You can accomplish full-lock through the use of a heavyweight governor mechanism, a cam system and a multi-disc pack. The flyweights on the governor mechanism move outward in order to engage a latching bracket whenever the wheel-to-wheel speed varies by approximately 100 RPM or more. This action retards a cam which, in turn, compresses the

multi-disc clutch packs locking both of the side gears to the case. The 100 RPM wheel-to-wheel speed allows for cornering with the differential lockup. At vehicle speeds above approximately 32 km/h (20 mph), the latching bracket overcomes a spring preload and swings away from the flyweights. At this vehicle speed, or greater, the differential is designed not to lock since added traction is generally not needed. The axle parts of the vehicles equipped with the locking differential are interchangeable with those equipped with the conventional differential, except for the case assembly.

You need to see one of these apart, the swing arm and spring

works sort of like the inertial reel of your seat belt restraint,

centripital force. The only problem is that you need to wait

just a moment after throttle application in deep mud in order to

get both axles to hook up. If you mash the throttle, they will explode

according to the 4x4 newsgroups.

 

 

Have a great one!

Riiiight, except for the fact that when you really need it to lock, your generally trying to get thru some slimey stuff and your wheel speed is in fact above 20mph.

 

Good luck trying to get it to lock when you need to mash the pedal down.

 

Save the money and go Detroit, E-Locker, or ARB is what i say.
