Finally, George moves onto setting pinion preload. This is controlled by compressing the crush collar for the pinion bearing by tightening the nut on the pinion shaft bit by bit. This crushes the crush collar and preloads the pinion bearing more and more until the correct rotating torque for the pinion gear measured by an inch pound torque wrench is established. This step took quite a bit of time! Now the hard stuff is done.
George used a light coating of OEM Nissan silicone seal on the Z1 Motorsports cover to ensure a proper, leak-free seal.
George torques the Z1 Motorsport’s high-capacity cover down. In this picture, you can see how the case sticks out to give more lube capacity over the stock case.

The axle seals are installed next using a seal driver and a light ball peen hammer.
