Initial Poppett  /  Plunger Setting Procedure  


Note: This procedure is for new and remanufactured gears from Power Steer Inc. or your vehicle manufacturer. All steering gears from Power Steer Inc. have had their poppett/plunger seats replaced and reset.

Caution: System must be flushed prior to installing new gear. This will ensure any debris or foreign matter that is in system does not damage your new gear.

Inspect axle stop bolts to ensure they are set to vehicle manufactures wheel cut or
clearance specifications.
bullet
Jack up front end so tires are off the ground
bullet
Start engine and let it idle
bullet
Turn steering wheel to full left until you contact axle stop. Pull hard on the wheel.

Turn vehicle off

 

Flushing Instructions - Pump  


When replacing PUMP only :


bullet Lift front axle off the ground and support with axle stands. Be sure and block rear tires.
bullet

Install pump. Do not reconnect return line from gear to reservoir, rather place hose into a five gallon bucket. Use a plug on reservoir to contain fluid.
bullet

Select proper fluid as recommended for steering gear or linkage system. Note: A good rule of thumb is to use twice the amount of fluid as the capacity of entire system.
bullet





When possible, disconnect the ignition so the engine won't start. An assistant is required to crank over the engine and to rotate steering wheel at same time.
Caution: Avoid hitting or holding against axle stop or damage will occur. At the same time fill reservoir with fluid and make attempt at not letting the pump run dry, this can be difficult at best. This allows the valve to open and the piston to force clean fluid through the pressure hose, valve, piston area and out of the return hose into five gallon container. Flush until clean fluid comes out.
bullet


Now re-attach return line to reservoir, top off reservoir, re-connect ignition system start engine and move wheel to one side. Stop engine and re-inspect fluid.
Caution: Don not over fill!
bullet




Start engine and turn steering wheel stop to stop approximately 6 times. Let run until system is at running temp and repeat turning steering wheel stop to stop six times.
Caution: Don not hold against axle stops. Note: Many steering systems have additional procedures for bleeding, may need to use manual bleed procedure. Determine gear type to see if has manual bleed screw to get any residual air out of system.

Flushing Instructions - Gear Box  


When replacing GEAR only :

bullet Lift front axle off the ground and support with axle stands. Be sure and block rear tires.

Install gear. Do not connect pressure and return hoses. Place pressure hose into five gallon container.

Remove return hose from reservoir, clean with solvent and air blow dry. Reinstall.

After re-connecting hoses, fill reservoir and crank over engine 5 seconds. Now turn steering wheel stop to stop without cranking engine. Top off reservoir.

Lower to ground and inspect fluid level.

Keep your system clean

We recommend when replacing a power steering pump or gear:
* Inspect all hoses and fittings     * Fluid is flushed and replaced       *Filter is changed
