Kaaz LSD 1.5 / 2 Way

What is the difference between 1.5-way or 2-way L.S.D.?

1-Way L.S.D. means that only when the accelerator is stepped on, the L.S.D. comes into use. The 1.5-Way L.S.D. means that when the car is braking, there is little L.S.D. effect and the 2-Way L.S.D. means that either when the car is accelerating or braking the L.S.D. is always active.
The difference between these are the shaping of the cam into different shapes for the pinion to fit. The diagram below shows how the 2-way version of the Kaaz L.S.D. operates.
But what if you are braking through a turn?

Sometimes you will hear these terms used in the business of L.S.D. trading and the racing department, etc. but what does it mean? As we mentioned before, when the accelerator is stepped on, the L.S.D. comes into use.

Where does the L.S.D. mount on the vehicle?

For every different type of car, the L.S.D. is fitted on different places. As we all know, the cars are separated into following categories: FR, FF, MR, RR and 4WD. Basically the L.S.D. is fitted between the 2 wheels that the drive train uses to propel the car. On 4WD cars, 3 L.S.D. are fitted.
One in the front, one in the center and one at the rear of the car.

What type of gear oil should I use?
A special blend oil made by KAAZ named "PowerTrain Gear Oil" can be used to keep your L.S.D. running for long hours under the best condition. The oil helps the clutch plates to grip and slip when needed.

How do I fix the chattering noise?

We understand that most car owners who use the mechanical L.S.D. are very disturbed by the chattering noise. As mentioned previously, the chattering noise comes from the friction between the clutch plates. This situation is normally caused by not doing enough break in and bad angle fit between the clutch plates.

The best to break in and remove the noise is by driving in a “figure 8” pattern for about 30 minutes and let the plates rub in to form a good fit. If this initial break in is not performed and too much torque is applied to the L.S.D. at once, the plates will form strange angles. Then the chattering noise will continue and may even cause damage to the L.S.D.

The oil used in the L.S.D. could also contribute to the noise problem. Poor quality oils contain large amount of tiny grains of metal which cause chattering noises. If noise still occurs after break in, try changing the L.S.D. oil. This usually eliminates or reduces the noise.

Oil which contains large amount of added chemicals will cause noise too. Users who are especially concerned about the chattering noise could think about changing to a better quality oil such as KAAZ Powertrain Gear Oil.
