If you need to ask how to replace the bearings, you probably don't have the tools or expertise to do the job. Take it to a small tool repair shop and they can do it in a jiffy.

go to milwaukeetool.com and you can download a copy of the owners manual with detailed instructions on this tool

You can try to lube the bushings, but they will always start to squeal again. I have tried just about everything, 2 cycle oil works good, wd-40 is a little thin, blaster works ok for a while, reg 3m oil forget it, motor oil, no, white grease, hard to get in there, axle grease, yes, but you have to take the bushings out. The oils, you don't have to take the saw apart. Hope this helps.

If the threads are not bound, you might be able to use a sharp pick to work the broken part out. Otherwise, you will have to drill out the center of the bolt with a small drill bit and use an 'easyout tool' that will fit tightly into the drilled hole which will allow the piece to be backed out. Good luck!

the field is in upside down, remove it and rotate it 180 degrees. Let me know

It is probably something like a 6365 and on all the Milwaukee products they have a switch wiring diagram but nothing for the switch. I would recommend going to a local repair center with the switch and match it up with a new one probably less than 15.00 If you give me your location with zip code I can direct you to the closest one. Let me know

here is a video showing exactly how this is done.

I dont know how old the tool is but when I worked on them it was notorious for exploding the commutator and damaging the brush holders, hopefully yours didn't do that. You have voltage at both brush holder then I would remove the brushes (UNPLUG TOOL FIRST) making sure they are not sticking in the tubes and while they are out rotate the tool by hand and look for any noticable difference in the commutator bars. Check all the connections from the field to make sure the circuit is complete like it sounds that you have done and if so that just leaves the two items I mentioned. Let me know if I can help further.

Screeching is always caused by dry metal on metal. It need oil on anything that spins or slides. See if the brake actually has fibre pads like the disc brakes on your vehicle. Google make model parts diagram All questions here need full make and model number, plus '(what it is)'. You got 2 of 3 :>D

If your Milwaukee 6390 circular saw is tripping the circuit breaker even without an extension cord, it could be due to a few reasons:

1. Overloaded circuit: The circuit may be overloaded with too many other electrical devices or appliances. Try unplugging other devices or turning off lights on the same circuit to see if that resolves the issue.
2. Short circuit: A short circuit can occur when the insulation on the electrical wires inside the saw becomes damaged or frayed, causing them to come into contact with each other. This can cause a sudden increase in current flow, which can trip the circuit breaker. Check the saw's power cord for any visible damage or wear, and consider having it professionally inspected if you suspect a short circuit.
3. Faulty circuit breaker: It's possible that the circuit breaker itself is faulty or worn out. Try plugging the saw into a different circuit and see if it still trips the breaker. If it does, the issue may be with the saw itself.
4. Motor overload: If the saw's motor is under strain or is overloaded, it can trip the circuit breaker. Check the blade for any binding or resistance, and ensure that the blade is sharp and properly aligned.

If none of these solutions resolve the issue, you may want to consider taking the saw to a professional repair shop to have it inspected and repaired.

check for a broken -plug wire -wire connection

You wired it incorrectly. If it didn't trip before, and now it does? recheck the way you wired it. Most power tools have a single throw double pole switch. It seems like you have wired Active to Neutral at the switch to cause an immediate power trip.

I suspect the reciprocating mechanism probably has a problem causing it to jam and the whining noise is possibly the safety clutch operating. You will need to dismantle the tool for a closer examination...

It is usually cheaper to replace especially if you wait for them to come on sale.

If it's new I would take my receipt and the unit back where I got it from. They likely have an answer for you.

Sorry this site doesn't have that diagram.

The motor is shorted plain and simple. I would just replace it. Buy a Dewalt, they are a better made drill/driver.
