SOURCE: Sparks from the Kirby Motor

1. Do you think this may be the problem?
YES

2. How come it continues to rotate?
Motor armature consists of multiple coils and just some of them burned so even though it keeps spinning it does not function properly.

3. Do I need to replace the armature?
We have switch replacement instructions HERE and they will take you as far as accessing the motor. We do not have motor assembly instructions yet but if you get that far - motor is not that hard to reassemble. You may have to spend some time getting tolerance ring back in and make sure you install finger spring properly.

Good Luck

Kirby G4 spaking after repairs???


Often the armature needs to be resurfaced when the brushes are replaced...Why were you replacing the brushes? Did the fan break?
It's really not that expensive to take it to a Kirby dealership for repair. Will run forever....Also it came with a lifetime rebulid warranty so even if it's trashed you can ship it back to the factory for rebuild for like 200 bucks :)

Tech drive has no power forward.


Dear Sir:
Download the instruction manual from Kirby, and see the section troubleshooting guide. And proceed according. If you say do not enough power. The batteries can be Not good replace or recharge very well.
Or test the power cord and trafo, and see if the power is o.k or replace. Use the VOM for to test the output voltage.
Another faulty can be the motor some winding inside is overheating and consequently faulty.
God bless you

Good Morning, after plugging the kirby in, I began to vacuum and a light started flickering from the back of the motor and then the sound while vacuuming starting getting louder and the light flickered...


The carbon brushes in your motor are worn out and "sparking" against the motor armature. DO NOT operate the vacuum in this condition or you may damage the armature so badly it will need replacement. Most vacuum dealers can replace the carbon brushes and resurface the armature. This should cost $40 to $50. If you need a new armature you are looking at $100 or more.

Hello can you help me please? I have a Kirby G4 vacuum cleaner, It did work ok until it started to give off burning smell and lots of sparks from the brushes. I have changed these brushes, the motor still...


Some debris, even sand or dirt, probably got into the motor, causing damage to the armature. If this is the case, you will need to replace the motor. The burning smell from the motor is generally a sure sign of a bad motor.

How can I get to motor drive on g4 does it have a belt


The power drive has a geared belt on the end on the armature which operates the power drive. The power drive has been out since 1990, and I have yet to see a bad drive belt in 1000's of repairs. The drive unit itself will fail very infrequently, and need replacement. The belt can be accessed be removing the handle, switch plate, and upper motor shell. The power drive unit must be loosened and dropped down to remove the belt.

Eureka canister vacuum cleaner Model 6865


The 6865 has a high rpm AMTEK Lamb motor, Brushes will seldom solve the problem at this stage.
Once the sparking and burning starts the conectiion between the brush and commutator is arcing and burning. If the sparks are blue, save your time.
A good service tech will run in brushes with a seating stone and a low voltage setup to allow new brushes to seat, but this is generally best accomplished on heavy duty , lower rpm motors.
IF YOUR ARMATURE IS SCRATCHY LOOKING OR WORN LIKE AN APPLE CORE,OR THE SEGMENTS ARE NOT PARALLEL IN THE SPACING YOU WILL NEED A NEW MOTOR.

Kirby G4


The bearings, there are 2 of them can be replaced. You will have to take the motor apart so you can get the armature out, one bearing is in the bearing plate, the other is on the end of the armature. If you do this, be sure to mark where each wire goes into the switch. If you mix up the 2 coming from the motor, it will run backwards.

You can replace the carbon brushes and most repair shops should have them. Also tho, the armature could be causing the problem, if you put in new brushs and it still arcs badly, then the armature is bad.
