![]() Different body styles have different length idler and pitman arms for example, the F body arms are longer than those in an A or G body and could cause alignment and front-end clearance problems if used in different body styles. These units will reduce steering wheel revolutions from lock to lock down to 2.25 to 2.75 turns.Īn important thing to remember when interchanging Saginaw gearboxes is to use your original pitman arm and idler arm if possible, to maintain the proper steering geometry. All of the Monte Carlo SS cars had these options. They are also 12.7:1 units and a little more difficult to find, but can be identified by a "YA" marking on the end cap (opposite where the steering column attaches) or by searching for cars with the F41 or Z65 suspension package. They were original equipment on 1983-'88 Monte Carlo, 1983-'84 Hurst Olds, 1985-'87 Olds 442, and 1984-'87 Buick Grand National or T-Type. Another option is to use late-model G or F Body units. The 1982-'96 S-10 pickups used a 14.0:1 ratio "605" series gearbox, which will interchange into earlier vehicles with some modification. These are very popular units because they are an easy bolt-in performance conversion. The 1969-'76 Camaros as well as 1964-'76 Chevelles, Malibus and Monte Carlos also used an optional quick ratio 12.7:1 unit, which will interchange with the higher ratio gearboxes. These gearboxes will improve the steering and handling for your car with a more responsive lower gear ratio and also reduce the steering wheel travel to 2.25 to three turns. These were original equipment on some mid-size models, and they can be transplanted into most other GM vehicles, if you can locate one from your local pick-a-part. Many enthusiasts have also found that an easy way to upgrade the handling on your car is to convert to a Saginaw quick-ratio power-steering box. You can locate one of the basic Saginaw "800" series power steering boxes in one of these vehicles:ġ964-'76 Buick and Pontiac full-size cars and Rivieraġ975-'76 Skyhawk, Seville, Monza and Starfireġ964-'76 Chevelle, Cutlass, GTO, Grand Prix, Lemans, Ventura and Tempestġ960-'76 Oldsmobile full-size cars including 1966-'76 Tornadoġ971-'76 Jeep Cherokee, Wagoneer, Gladiator and J-series pickupsġ972-'75 International Scout and Traveler This is a good thing to remember when you begin your search for a replacement. The more responsive 14.4:1 ratio gearboxes replaced the earlier 17.5:1 ratio boxes in most models by 1973. Aside from the mounting bolt pattern (most are 4-bolt mount but there are two different three-bolt mounts, as well), these units are all interchangeable. You can substitute between both of these units. 813-inch input shaft diameter, and most will have 31 splines on the input shaft. Both the 3.5-inch and the 3-inch-bore gearboxes have a. The mid-size gearboxes were rated at a 14.4:1 steering ratio. The travel on the smaller-piston unit was three to 3.5 turns lock to lock. Mid-size and smaller models used a steering box tagged 5691676, and these units used a 3-inch piston. These units were rated at a 17.5:1 steering ratio. These units had a 3.5-inch piston diameter, and the pitman shaft will turn anywhere from 3.5 to four turns between fully locked left and fully locked right. Station wagons, full-size cars and large front-wheel-drive cars used a heavy-duty gearbox usually identified by GM part number 5687962. GM also used two gearboxes, depending on the weight and size of the model. ![]() The 605 units use a single snap ring that holds a round cover into the top of the housing. An 800 unit has a four-bolt cover on the top of the unit (the end of the shaft opposite the pitman arm spline). The only major difference between these two units is how the pitman shaft is held into the unit. You will often see this gearbox referred to as an "800" or "605" unit. They are referred to as recirculated ball-type because they use the same ball bearings on both the worm gear and the sector gear to reduce friction within the housing. The Saginaw gearbox is a rotary-valve type unit using recirculating ball bearings. Looks like they are all the same, might be mistaken. I found this info on steering gear boxes.
