STEERMAN CYCLE
ELECTRIC POWER STEERING INSTALL INSTRUCTIONS
1973-1987 Chevy/GMC square body 4×4
STEP 1: Remove Old Steering Components
- Remove the stock steering shaft
- Remove all hydraulic power steering components (pump, hose, cylinder, and brackets)
- MAY REQUIRE LOOPING THE TWO HYDRAULIC LINES TOGETHER(ON HYDRAULIC GEARBOX)
- Remove two top motor mount bolts
- install grommets to protect wiring harnesses
Step 2: Install Electric Power Steering
- Install the Front shaft onto the front of the EPS unit
- Install the Rear shaft onto the back of the EPS unit
- Cut inner fender with supplied pattern with locating measurements
- Tighten the pinch bolt on the front shaft
- Install eps unit and shafts as one unit
- Install the front shaft onto the gearbox first. Next, install the rear shaft onto the steering column
- The steering column may need to be moved toward the driver for easier installation
- Install motor mount bolts into the eps bracket and tighten
- Install a set screw in the front shaft at the gearbox. Tighten the set screw and nut on the rear shaft at the steering column
Step 3: Wiring
- The ground wire in the bag goes from the engine to the firewall.
- Grounds are very important as with any electrical system. Clean any area to the bare metal where the ground is being installed
- Run eps unit wiring alongside the factory headlight harness. Next, run into a 1 ½” hole in the firewall above the distributor and throttle area
- Install the main power harness from the battery along the top of the firewall and behind the engine through a hole in the firewall above the throttle pedal. (do not hook up battery power yet)
- Install the module with bracket inside the cab, under the dash. Directly beside the throttle pedal works best- as all wires are built to a length of this location
- Use two self-drilling screws to mount the module bracket in place
- Install a small self-drilling screw into a small black ground wire to the firewall
- Hook up a small red wire to fuse in the factory fuse box. (key on power) use the brass clip to fit around the fuse or use the factory accessory spade
- Install the sensitivity knob on the right side of the steering column on the dash. Other locations are fine just keep in mind moving parts (clutch linkage and brake linkage.) under the dash when installing.
- Plug in all wiring connections to the module.
- Zip tie or use cable clamps to secure all wiring harnesses and double check all bolts are tight.
Step 4: Almost Done!
- Double-check all bolts are tight and wiring harnesses are not inferring with moving or other harmful components (exhaust or sharp edges)
- Install main power at the battery.
- Turn the key on. Listen for the module to make a “click” noise (if none turn the sensitivity knob up or clockwise,)
You now have the best power steering you or your pickup could ever need.
Enjoy!!
