I understand that the 2 blue wires are overtemp detectors. I removed motor to service brushes and the 2 united blues were right below the motor. Is there a proper place for it or does it just lay down on the bottom plastic cover? I can see other end is connected to the controller board.
I found that the thread pitch on that shaft is actually standard 1/2"-13 tpi Left Hand. I had some from something I worked on over 30 years ago and had to order 10 minimum, so had 9 left over in my tool box. Every dimension for the shaft I got was 17mm diameter and 24mm length of shoulder is in metric. However for the threads I measured either 12.45mm X 2.0, but that was too close to 1/2" by 13.
Worked good. I had to spin it up a little and grab it. You can get a pwm generator from Amazon for 10 bucks set to 20 hz and run it without the treadmill panel
I tried it but the flywheel is really locked on. Do you have a tip for getting the tough ones off? this one is a new 3.8 motor. Was I suppose to take the screw and washer off?
Hello, nice video ! how can i remove the flywheel of the treadmill ? mine has a sort of allen bolt in the middle of the flywheel and nothing from the rotor comes from the back end of the motor. Thanks
What do the blue wires on the motor do? You didn't have them plugged into the board so are they not needed (should I cut them off) what purpose do they serve?
There's a thermal cutoff switch in the motor that opens the mains circuit when the motor gets too hot. In this video he has a jumper wire on the control board to bypass the thermal switch.
OK people I have been looking at many of these treadmill motors...He did good here with it...Now the way he did the pulley is not safe and that only a 1/2 pulley... OK i have 4 motor only 2 real theadmill controls (MC 60 the easiest to work with) as some one said its a 9/16 shaft all you need to do take the controller and hook up the so works and get yourself a angle grinder start motor take the angle grinder, forget something you also need a 5/8 shaft pulley now just run motor a start grinding away until the pulley fits I just did 4 motor in about a hour there you go...
So looking directly at the flywheel facing you the flywheel turns clockwise as default. In that condition if you grab the flywheel, the flywheel will be the same as if you are turning clockwise if you start the motor since you are stopping it from going clockwise. So the flywheel must reverse threaded if you have turn the motor counterclockwise to remove the flywheel. Is this correct?
@@BrandonsGarage Mine absolutely will not budge. I am using its own control board with a 5K potentiameter to get the motor going. And I have this same motor. 1.65 HP 90V and the control board look identical.
You are tearing apart $150 motors for $3 of copper? ...I didn't know flywheel was threaded on so that helped me and I appreciate video for that:) I did just put vise grips on rear of shaft to loosen flywheel..very easy.
@ 1:40 "COUNTER CLOCKWISE"? NO! If the MOTOR spins CW then the pulley would self tighten against the load. You turn it CLOCKWISE, the same way the motor spins. I listened to another FoolTuber who said the same thing. I ruined a perfectly good motor because of him (not you, "him"). So with broken motor in hand I disassembled it and locked the armature up in the vice and turned the flywheel CLOCKWISE! I'll say it again so nobody thinks I mis-spoke - - - CLOCKWISE. How did I ruin a good motor? I held the tail shaft and forced the flywheel to rotate COUNTER clockwise and BROKE it. I was lazy and didn't want to bother to think it through. After the disaster I decided to think it through. That's when it dawned on me - the flywheel must be spun off the same way the motor spins. When you reversed the polarity of the motor it spun CCW. (@ 2:15) That means the flywheel had to be spun OPPOSITE of the motor's new rotational direction. In other words, CW (Clock Wise)
I need to remove the flywheel from my Life-fitness treadmill motor (2 HP). Flywheel is reverse threaded. Looks like it is stuck badly. I ran the motor in anti-clockwise direction at highest speed (10), but flywheel is not coming off. I clamped the flywheel to stop rotation, but the control panel turns off the motor if rotor is not rotating. Other end of the shaft is not protruding out (slightly recessed), so clamping or holding the rotor to stop rotation while manually turning the flywheel is not possible. I have been searching for solutions and landed on this video, but this technique has not worked for me. Any other ideas you would try if your flywheel did not come off when you stopped reverse rotation Brandon?
@@BrandonsGarage Everybody seem to be able to simply hang on to the pulley/flywheel and run the motor backwards and the pulley just come off. Mine don't even budge. The motor just humms. I am running the motor with its own control board that I took off from the treadmill. I like to use the sucker to turn a 14 inch metal cutting blade. I would hope this motor might accomplish the task. I guess I will find out. Either install a V pulley or if I can't take off the flywheel, then I will have to use it the way it is and change the pulley that is at the other end that turns the blade. I plugged in a potentiameter on the control board to control the speed of the motor.
So glad I watched this before I pulled out what hair I have left. Thanks!
Thanks for those numbers. great motor for a electric mower build.

If yours was left hand thread then the motor must have spun Counter ClockWise (CCW).

Because the motor just stalls n hums if you start it up with the Kung Fu grip allrdy n place? That's what I'm currently dealing with
I never would of figured that out thank you so much😂
Ooh well I guess I’m SOL because mine has a stuck setscrew and a keyed shaft
Thank you! I have the same motor and have been hitting it with a hammer!!! Doh
Were your controls adequate to drive the larger motor at full speed?
I tried it but the flywheel is really locked on. Do you have a tip for getting the tough ones off? this one is a new 3.8 motor. Was I suppose to take the screw and washer off?
Did you get it figured out ? Same problem here
Please tell me how to disassemble and replace the bearings in the P.MD.C. treadmill engine. motor model A17225M063
Looking at the shaft which way do you turn the pulley to take it off? clock wise or counter clock wise
Thanks for sharing your knowledge. Do you need to have the flywheel attached when making a belt grinder?
It helps...
Hello, nice video ! how can i remove the flywheel of the treadmill ? mine has a sort of allen bolt in the middle of the flywheel and nothing from the rotor comes from the back end of the motor. Thanks
I used a C clamp to hold the fly wheel, then turn the hex screw counter clockwise with a hex ratchet tool

correct.
the thoery here was the spinning mass of the pulley, mixed with the sudden stop of the motor, should allow it to spin itself off.

thats the exact same motor I need.. The bearing is shot. Do you know where I can get a bearing (Front)?
pull out the brushes, tear the motor down, get the dead bearing out. write down the number printed on it and take that to your local auto part store

I don't, neighbor does.
I HAVE ONE OF THOSE RPM READERS!
Can I have it? lol
Hello. Nice video. I tried the same and i couldnt....
Thank you
You're welcome
AWESOME 👍 WAY TO TAKE IT OFF IT WORKED SO EASY THANK YOU

Be aware that some flywheels are actually PRESSED on, and not threaded.
Fue de gran ayuda ,gracias.
Thank you!!

This worked for me!
Bom
Whats contact number Brandon, been trying to reach out to you bud
Email sent
sorry, its evinrudegarage @ gmail dot com
I shouldn't type while tired.
So should I rotate the flywheel closewise or Anticlock wise to remove it ?
Why are you mumbling? Speak clearly.
cant, have no tongue.
