Disassembly 1. Remove dash panel bracket and store bracket in a safe place to prevent damage to mounting capsules. 2. Place column in a vise using both weld nuts of either set A or B, Fig. 29. The vise jaws must clamp onto the sides of weld nuts indicated by arrows shown on set B. Do not place column in vise by clamping onto only one weld nut, by clamping on one weld nut of both sets A and B or by clamping onto the sides not indicated by arrows, as damage to column could result. 3. Inspect steering shaft to determine type of thread used for steering shaft nut.

The flow control valve supplies fluid to the proper side of the rack piston when the steering wheel is turned. The pump mounts on the front of the engine. Two different rack designs are used. The 80 and 90 models utilize a rack assembly that extends the rack from one side of the housing. The steering links are attached to a bracket on end of rack. The 100 and 200 models use a rack assembly that is supported at both ends. The steering link bracket is attached to the center portion of the rack, through a window that exposes the rack. Rubber boots protect exposed portions of the rack from dust and contamination.
