User manual WHITE BROTHERS CYCLING AP-1SERVICE

[. . . ] Service Instructions for Seat post service (27. 2 or 26. 8). Each size will use a separate kit. 1. 16. Prior to doing any service on the AP-1, you must remove all air from the seat post. [. . . ] Inspect the upper DU bushing (#16) for wear (note the DU bushing is pressed into the top of the lower tube). If wear is noted, please contact White Brothers for service or service parts to replace the DU bushing. If no wear is detected, lube the DU bushing and the composite bushing (#19 pressed into lower tube at pin hole) with grease * (see note below). Apply a small amount of grease on the stanchion (#14) and insert the stanchion into the lower tube. Apply grease to the piston o-rings and to the lower part of the lower tube. WARNING Apply a small amount of Locktite 271 on the threads of the valve body (#7). Use an Allen wrench to carefully insert the piston and valve body into the lower tube. If the valve body is too tight, the stanchion assembly will bind when worked inside the lower tube. Work the stanchion assembly several times to make sure that the valve body is not too tight. Insert a new guide pin (#2) through the lower tube and stanchion assembly (Note you may need to rotate the stanchion assembly for the pin to fit properly). Apply Locktite 271 on the threads of the flat head screw (#13) and tighten the flat head screw into the guide pin. CAUTION do not over tighten the screw, as it will cause the stanchion to not work smoothly.
