3. Install 2 SHCS removed in Step 1 opposite one another, threading them approximately halfway in. Using the two SCHS as a sort of handle (or use Kurt Spanner Wrench P/N: DL640-307A-SA), loosen the second (larger) portion of the retaining nut. You should notice a washer and spring coming out of the end of the hydraulic unit. - Page 24 3. Continue to do so until the washer is slightly recessed inside the hydraulic unit. This is crucial, otherwise the spring will keep the hydraulic unit from completely bottoming out in the vise body counter bore. (See Fig.19) Fig.19 0.015 4.
