Have a craftsman belt sander. Armature bearings are bad. One end has a threaded drive pully which needs to come off to get the assembly out of the main housing. My guess is I need to remove end bearing to...

Be careful about putting the armature in a vice. Clamping it tight enough to pull a bearing may damage it. Now, if you have access to the first bearing, get a small bearing puller of this style This is just an example to show what type should work. If there is not room for this, then there are other pullers made that have arms that will fit within the 1/8" clearance you have.

On the pulley, if it is a nut holding it on, then a regular socket will work. As stated be careful clamping the armature so as not to damage it. I would take a block of wood, say a scrap pc of 4x4 and bore a hole through it with a hole saw that closely matches the diameter of the armature. Cut it in half long ways, removing enough material so that when you use it to clamp the armature, the two half circle wood pcs don't touch. That way, it spreads the clamping force around a little more of the diameter of the armature.

If the actual pulley is threaded, then clamp the same way and you may have to rig something. Are there holes or slots in the pulley that a spanner wench would work on? There are several universal/adjustable spanner wrenches available for that type of thing. Check to make sure there is not a set screw in the hub of the pulley that keeps it locked from turning. A photo of this would make it easier to make suggestions.

Where to lubricate fan

What type of fan do you have? If it is a desk or stand fan, you need to add oil to the front bushing/armature (accessible by taking off the fan blade) and to the rear bushing. To reach the rear bushing, you need to take the motor cover off - pull the oscillator push-pull lever up until it disengages, then using a phillips screw driver, unscrew the retaining screw of the motor cover. When the cover is out, you need to unscrew 3 retaining screws on the oscillator assembly at the back of the motor. When the oscillator mechanism is out, you will see the motor armature at the back of the motor (has a threaded end). Add a little oil to the bushing of the armature. Then reassemble (reverse order - secure the oscillator assembly with 3 screws, install the motor cover and screw the back, insert the push-pull lever and you're done). Hope this may help.

How do I replace the fan assembly cannot hold armature assembly to get inner bearing out without damaging armature assembly

If you are replacing the fan assembly because the internal thread that holds the rubber/velcro pad has stripped, there might be an alternative.

I had the same problem with my PEX 12AE, which I believe is a similar sander. I found that the hole is threaded a good bit deeper than the screw, so I got a longer screw and so far it's holding ok. If/when that fails, I might try repairing the thread with an insert.

Curious to know how you managed with your sander.

How do you remove the crown gear?

The gear on the end of the armature is held on by a metric nut. The armature shaft is threaded. The larger gear is press fit onto the shaft. You need a hydrolic press to remove it.

On the armature is there a bolt that is press on,

A bolt is never pressed into a hole. Your question is not clear to me. Generally, a key & keyway is to keep the rotating item in time. Another means is to keep the rotating item from sliding off the shaft. Common ways:
1) set screw(s) from the item hub over the keyway and sometimes against the shaft
2) Bolt threaded into end of shaft, or nut screws over threaded end....mamy time it is a "LEFT Handed" thread (Turn counter clockwise to loosen)

My Bosch 3107dvs random orbital sander stopped working. The screw that holds the sanding disk stripped the part that it screws into. I can't tell from the exploded parts diagram, which part I need to...

Drawing REF:

To remove the Dust Fan/Coupling Assy. I did the following: I disassembled the plastic housing, removed the Backing Pad Pos. 733 and Dampening Ring Pos. 51.

It seems the Star Washer Pos. 29 holds Bearing Pos. 30. onto the armature shaft and the Coupling Pos. 27 seems to be stuck in Bearing Pos.29. I used a 30mm long M7 hex-head bolt and 11mm ratchet turning clockwise (std RH thread) to pull the Coupling and Star Washer off. Luckily, there was enough thread left in the coupling to do this gear-pulling action with the longer bolt.

To remove the rest of the Fan Assembly I removed the 2 screws Pos. 43 holding the Brush Holder Assembly, Noted the position and removed the Spring Clip Pos. 32, then removed the Armature w/ Fan and Dust Fan/Coupling Assemblies. Firmly gripping the armature I was able to remove the Dust Fan from the armature by turning it clockwise (LH Thread).

Now that I have removed the parts and believe I will be able to reassemble them, I have ordered a new Dust Fan/Coupling Assembly.

I hope this helps someone else having a similar problem.

Need to replace front vacume propeller

You will have to take most of the vacuum apart to replace your fan.
First; remove the handle assembly by pressing the button on the front of it near the base. Remove the bag unit by twisting the rear of the emptor away from the body, and remove the front nozzle assembly by rotating the belt removal part to the "off" position and flipping the latch at the top of the nozzle.

There's a screw on the very back above the self propel select, and one on the top of the plastic where the cord attaches, removal of these will let you remove the rear plastic piece. Then there will be two more screws above the main power switch, and two on the front of the housing under the headlight. Remove the power cord, and then you can lift the rear housing from the main body.
Now you can remove the screws from the front of the fan housing; I believe there are five. Make sure you keep track which screws came from which position, because they are all different sizes.
To remove the front of the fan housing, put a flat-head screwdriver in the gap at the top to the side of the headlight assembly and pry it apart.
To get the motor pulley off you'll want to grip the pulley with a pair of vice grips, and use a wrench to hold on to the motor shaft in the rear of the machine. Look at the shaft that runs to the rear from the armature, and you should be able to locate a flat section which will allow you to grip it with a wrench... I do not recall the exact size, but there is a standard one that fits it perfectly. The pulley can then be removed. Note that it is reverse-threaded. Keep in mind that you will need to replace all the little plastic washers and rubber gaskets and things that are on the shaft with the fan. They are usually included with the Kirby fan kit, but if not make sure you find some before attempting the repair.
Before reassembly, you'll want to apply a thin layer of adhesive around the edge of the fan housing, making sure you don't glue the safety switch on the front into place.

Reassembly is the reverse of disassembly.

Good luck.

Blade assembly does not tighten

problem could be the armature ring/ drop. it's for the bearing stopper. if the ring slip off from the grove, all you to do is to put it back to the grove & make sure that the grove are in good shape..its common problem for older armature type.
