BNR32 Engine:RB26DETT until Feb.'93 Transmission: FS5R30A Clutch type:Push



・Copper seal washer required (Genuine Nissan part 46237-A4600)

・Coppermix and non-asbestos clutch discs are equipped with cushion plates and should not be used with the big operating cylinder.



Features:

To reduce the pedal load when using a sports clutch, improve half-clutch operating characteristics and
provide proper clutch connection positioning, the size of the operating cylinder was increased from 3/4 inch (ø19.05mm) to 13/16 inch (ø20.54mm). This reduces pedal pressure by as much as 14% compared to a standard part.



Product Warnings:

Because the cylinder stroke volume is decreased when using the big operating cylinder, the stroke should be correctly adjusted:

1. Before removing the standard operating cylinder, ensure that air does not enter by clamping the hose securely with a hose clamp.

2. Fill the big operating cylinder to be installed with brake fluid, and connect it to the hose after emptying all the air from it.

3. Even after carefully completing steps 1 and 2, some air may be remain. Air in the hose will change the pedal stroke and clutch feeling. Since it is difficult to remove air from wide diameter hoses and pipes such as the U pipe, you should double check to be sure that all air is completely evacuated.

4. Vacuum pressure is the easiest way to accomplish step 3 (use the U-pipe eliminator adaptor which comes with the NISMO Clutch Hose).
