Warning: Use only the tubular wrench to tighten the schrader valve; ordinary wrenches or pliers can overstress the threads in the nylon air cap. Spring Spacer Compression Valve Valve Spring 4 Rebound Adjustments figure 6 12) Rebound is governed by the size of a small hole in the adjuster. The adjusters installed in your cartridges are rated for "medium" rebound. In the small bag included in the package are adjusters rated for "slow" and for "fast" rebound damping. 13) Adjusters are coded to distinguish them. Slow rebound adjusters are marked #1, medium are marked #2, and fast are marked #3 figure 7 (figure 6). 14) To change an adjuster, deflate both cartridges and remove the schrader valve stems. Insert the long end of a 4mm allen wrench through the hole and into the top of the adjuster. Rotate the adjuster counterclockwise several times until it finally comes loose. When the adjuster is free, it can be withdrawn on the end of the allen wrench by tilting the wrench slightly and pulling it up through the valve stem hole (figure 7). Caution: Just under the adjuster are the compression valve and spring; these may fall out if the fork is turned upside-down while the adjuster is out. NOTE: Never install more than three spacers under the negative spring, fork travel will be reduced. See exploded view for proper installation of the negative spring system. 5 Disassembly/Assembly Negative Spring System 1) Let air out of Total Air Cartridges by removing dome-shaped dust caps and compressing valve core. 2) See Basic Fork Disassembly/Assembly for how to remove and reinstall lower fork legs from fork stanchions. 3) With fork legs removed, loosen nylon bottom out cap from fork stanchion. NOTE: A proper fitting pin spanner or WB pn 97-716 tool is required. Remove entire dummy shaft assembly noting order of parts. Adjust negative spring preload and/or spring per Negative Spring Adjustments above, or simply remove the travel limiter and compression bumper and slide assembly out the top crown with cartridges and top caps removed. [. . . ] NOTE: Do not tap fork legs onto stanchions, DU bushings can be dislodged. Slide both fork stanchions into lower fork legs and fully compress. Fully tighten 6mm allen bolts in lower fork legs. Slide the foam ring into each lower fork leg carefully tucking it in on all sides. [. . . ]
