Horizontal & Vertical Transmissions: Removal
Remove seat assembly and motor. Fasten a 10" "C" clamp from mounting base assembly to upper channel assembly, just tight enough to keep it in place while removing cotter pin and front (5/16") clevis pin. With pin removed, slowly release tension on vertical spring. Remove cotter pin and rear (3/8") clevis pin and upper channel assembly, then remove horizontal spring. Remove through bolts from each end of side rail assembly and from transmission assemblies, then separate rails and transmission assemblies.
