I need to replace the motor brushes in my norelco hp 1132 shaver

It's true that Norelco does not sell parts for this unit, but you can buy a exact replacement for the pump motor here:
https://www.amazon.com/dp/B0146XUE4I/ref=cm_sw_r_api_i_KGSBKR1BPW349RR3YRSB_0?psc=1.
The only difference will be the length of the replacement motor shaft is too long, but this can be modified using a Dremel cut-off tool.

Getting to the motor is a bit involved, but it is possible to do so without breaking anything.

You'll need a T-8 driver and a small flat screw screw driver

Begin by releasing the bottom, remove the fluid cartridge, and turn the unit upside down. Find and remove the (3) T-8 screws along the bottom perimeter.

Next, use the small flat screwdriver or plastic pry bar to lift the outer case over the upper edge of the rear power supply socket and slide the outer case down. You'll also need to press the cartridge release button to clear the case

Slip the outer case off the bottom. You'll need to twist it somewhat to clear the base.

Now find and unplug the two side wire connectors (purple/white and orange/white wires) and slide the rear power supply connector off of the back of the unit, leaving it connected to the circuit board



Now find and remove the (4) silver T-8 screws holding the base to the circuit board. Back the screws out only far enough to separate the base from the circuit board, leaving them attached to the black base so as to make it easier to reinstall later


Gently separate the base from the circuit board. You will feel a bit of resistance as a hose separates from the base. Note where it attaches for later reinstallation.

Now we need to remove the "legs" to gain access to the bottom of the pump. Place the separated vase upright and compress the springs to lock the legs in closed position. Note the two hooked ends sticking up. You will be using the small flat screwdriver to pry these towards the center.
Open the "legs" by pressing the side button. Slide the flat screwdriver down the side of the base and use it to pry the hook so you can pull the leg out. You'll have to pull slightly on the bottom while doing this until you feel the hook release, and then you'll move the screwdriver to the second hook on this leg and repeat. Then move to the other leg and do the same. It takes a bit of practice but it'll eventually release. Be gentle.
Separate the leg unit from the rest of the base. Be careful not to tangle or damage the coil springs. Set the legs and springs aside.

Inspect the bottom of the pump. Gently pry the bottom cap off of the pump with your fingernails.

Gently pry the impeller off the bottom of the pump motor shaft using a tiny screwdriver. Be careful not to damage the impeller.


Turn the pump unit over. Use small screwdriver to gently pop loose the pump motor restraint (3 points) Lift the pump motor out of the housing. You can now clean the housing.
Remove the two seals from the impeller end of the motor. You will transfer these to the replacement motor.

Use soldering iron to remove the wires from the old motor and solder them to the new motor. Use a Dremel tool to shorten the shaft of the replacement motor to match the length of the old motor.

Installation is the reverse of removal except I recommend saving reinstallation of the "legs" and springs for last - put everything else together first, including the outer case. Then line up the springs and legs and carefully press them together.

You will need to disassemble the heads and brush them out. You can soak the parts in rubbing alcohol if they are gummed up. This will loosen the material up so that it can be brushed away. An old toothbrush works well for this.

It sounds as if the inside of the shver is full of old hair and the like. It needs a good cleaning. SOMETIMES this does not solve the problem and the brushes in the motor could be bad. it is cheaper to replace the shaver than fix one.

I have no way to get you a copy of an owner manual as this is a very old model made before Norelco begnning offering on-line user manuals.
There are some parts available for your shaver. The parts most likely to need replced are the shaver heads and the motor brushes. You will find these parts at shaveroutlet.com. See links below

It is suggested that all shavers have the heads lubricated. Norelco makes a product for this and it is also found at shaveroutlet.com

http://shaveroutlet.com/norelco-al80-razor-lubricant-spray-p-255.html

Internal lubrication is not often needed but if your shaver is a bit noisy a 3 in one oil can be used. You will need to take off the outer case of the shaver by removing two screws on the one side and one screw on the other. Once the insides are removed, you can remove the two metal clips that hold the gear housing on. You can then remove the gears and lubricate the spindels they fit onto and oil the pinion gear.
Reassemble in reverse order

Your original symptoms sure sound like dying batteries. Brushes can wear out. Check if it runs better if you change the orientation of the shaver. Does holding it upside down make it work better or worse? If the speed changes, its probably the brushes. You can buy new brushes, but the Norelco repair place will probably give you a hard time since they want to repair it for you so you have to insist. I have made brushes for the shaver by filing down brushes from some other motor, but this is messy and doesn't always work.

if the charge indicator is working and dispays full, you probably have some type of loose connection inside. Check the connection between the circuit board and motor. Less likely but possible that the motor brushes may be worn out. One way to test this is to remove head and turn shaver on...then turn one of the three gears by hand in a clockwise direction. If it then starts to turn slowly on it's own, the brushes are probably bad
