All Pro SPC85

Must hold or "prop" closed the on plunger to operate. (not advised to do this)

The entire plunger assembly can be pulled from the heater. I think something has fallen off.

Where is the neutral safety switch located on the transmission and is there another switch that would keep the starter from engaging?

If it is an automatic it is part of the Range sensor switch on the transmission where the cable hooks up from the linkage.

Lid does not seal---very loose

If sprayer doesnt seal against pressure, I suggest check cover gasket A (image 1). Check pump cylinder gasket B (image 2) and additionally, check the procedure if pump dont build pressure. on how to remoce pump cylinder on follow lines.


If pump doesnt build pressure... in most instances, failure of the pumo to build air pressure in the sprayer is due to dry or worm plunger cul leather. To work on cup leather, always remove plunger from pumo cylinder. Do not attempt to oil cup leather through breather hole in **** cap.

First, unthread pumo cap A (image 1). If cap is too tight, and if pumo will build even slight temporary pressure, pressurizing the tnak will make it easier to loosen cap. Once cap is lossened, release tank pressure. Hold pump cylinder by inserting hand through tank filler openning (image 2), and unscrew cap all the way. Pull plunger from cylinder, and remove cylinder from inside the tank.


Place a few drops of clea oil (not heavier than SAE 30) on leather, and massage into leather until it is soft. Replace plunger cup leather if damaged (image 3). to remove plunger leather assembly, use coin rather than screw driver in the slot of the plunger cup retainer. To reassemble, hold pump cylinder in tank openning, with squared edge of flange, at top of cylinder, toward tank wall.


Hope this helps to solve it.

Install power brake booster on 1988 ford ranger

REMOVAL & INSTALLATION NOTE: Make sure that the booster rubber reaction disc is properly installed if the master cylinder push rod is removed or accidentally pulled out. A dislodged disc may cause excessive pedal travel and extreme operation sensitivity. The disc is black compared to the silver colored valve plunger that will be exposed after the push rod and front seal is removed. The booster unit is serviced as an assembly and must be replaced if the reaction disc cannot be properly installed and aligned, or if it cannot be located within the unit itself.

  1. Disconnect the stop lamp switch wiring to prevent running the battery down.
  2. Support the master cylinder from the underside with a prop.
  3. Remove the master cylinder-to-booster retaining nuts.
  4. Loosen the clamp that secures the manifold vacuum hose to the booster check valve, and remove the hose. Remove the booster check valve.
  5. Pull the master cylinder off the booster and leave it supported by the prop, far enough away to allow removal of the booster assembly.
  6. From inside the cab on vehicles equipped with push rod mounted stop lamp switch, remove the retaining pin and slide the stop lamp switch, push rod, spacers and bushing off the brake pedal arm.
  7. From the engine compartment remove the bolts that attach the booster to the dash panel. To install:
  8. Mount the booster assembly on the engine side of the dash panel by sliding the bracket mounting bolts and valve operating rod in through the holes in the dash panel. NOTE: Make certain that the booster push rod is positioned on the correct side of the master cylinder to install onto the push pin prior to tightening the booster assembly to the dash.
  9. From inside the cab, install the booster mounting bracket-to-dash panel retaining nuts.
  10. Position the master cylinder on the booster assembly, install the retaining nuts, and remove the prop from underneath the master cylinder.
  11. Install the booster check valve. Connect the manifold vacuum hose to the booster check valve and secure with the clamp.
  12. From inside the cab on vehicles equipped with push rod mounted stop lamp switch, install the bushing and position the switch on the end of the push rod. Then install the switch and rod on the pedal arm, along with spacers on each side, and secure with the retaining pin.
  13. Connect the stop lamp switch wiring.
  14. Start the engine and check brake operation.

The lever that pulls up and down on the spout doesnt work well .

You can adjust the length of the connection piece which opens/closes the plunger to close the drain. Remove the handle assembly from the tub and lengthen/shorten the assembly as needed to be able to seal the drain.

Won't start

82059263 The [PG] starter motors are [non-]repairable starter motors. They have pole pieces that are arranged around the armature within the starter housing. When the solenoid windings are energized, the pull-in winding circuit is completed to ground through the starter motor. The hold-in winding circuit is completed to ground through the solenoid. The windings work together magnetically to pull in and hold in the plunger. The plunger moves the shift lever. This action causes the starter drive assembly to rotate on the armature shaft spline as it engages with the flywheel ring gear on the engine. At the same time, the plunger closes the solenoid switch contacts in the starter solenoid. Full battery voltage is then applied directly to the starter motor and it cranks the engine.

As soon as the solenoid switch contacts close, current stops flowing thorough the pull-in winding as battery voltage is now applied to both ends of the windings. The hold-in winding remains energized; its magnetic field is strong enough to hold the plunger, shift lever, starter drive assembly, and solenoid switch contacts in place to continue cranking the engine. When the engine starts, the pinion gear overrun protects the armature from excessive speed until the switch is opened.

When the ignition switch is released from the START position, crank voltage is removed from the starter solenoid S terminal. Current flows from the motor contacts through both windings to ground at the end of the hold-in winding. However, the direction of the current flow through the pull-in winding is now in the opposite direction of the current flow when the winding was first energized.

The magnetic fields of the pull-in and hold-in windings now oppose one another. This action of the windings, along with the help of the return spring, cause the starter drive assembly to disengage and the solenoid switch contacts to open simultaneously. As soon as the contacts open, the starter motor is turned off.

Here is the wiring circuit for the NEUTRAL SAFETY SWITCH which is what I believe to be your problem, do the reverse lights come on when the keky is ON and the transmission selector is in REVERSE? IF NOT you have a renge selector problem.
if you find this information helpful please give me a good rating and please contact me if you need any further assistance.
Thank you, Randy
