Wagoneer L6-258 4.2L VIN C 2-bbl (1982)
Fig. 4 Model 605 power steering gear disassembled
There are two types of Saginaw integral rotary valve type single piston steering gears. The two different types of gears can be identified by the
configuration of the side covers. The Model 605 gear has a round side cover, secured with a retaining ring. The Model 800-808 gear has a rectangular
side cover, secured with four bolts. Also, note that the Model 800-808 gear incorporates balls in the rack piston, while the Model 605 gear does not.
The power steering gear operates entirely by displacing oil to provide hydraulic pressure assists only when turning. As the entire gear assembly is
always filled with oil, all internal components of the gear are immersed in oil, making periodic lubrication unnecessary. In addition this oil acts as a
cushion to absorb road shocks that may be transmitted to the driver.
The steering shaft, hydraulic valve, worm and rack piston nut are all in line, making a compact and space saving steering gear. All oil passages are
internal except the pressure and return hoses between gear and pump.
NOTE: If the steering gear housing ball plug leaks or is raised above the housing surface on vehicles built prior to the 1985 model year, repair the
housing as follows:
1. Seat ball in housing using a suitable punch, then spray ball and housing with Loctite Solvent No. 75559 or equivalent.
2. Dry area with compressed air, then apply Loctite Sealer No. 290 or equivalent to both ball and housing.
3. Allow sealer to cure for approximately 2 hours, then reinstall steering gear.
This procedure is not effective on models produced after 1985. If ball plug leakage is evident on these vehicles, the entire gear assembly should be
replaced.
