Motor Clip

I found that I replaced more parts than I needed to fix fhis problem. The source of the rumble was the blower wheel connection to the motor, allowing the wheel to wobble (plastic wheel flat spot worn off over time, no firm lock to the motor shaft). But the dryer should be good for another 10 years!

Disconnect dryer from electrical outlet and exhaust.

Remove the back access plate to release the belt from the pulley. Remove the two screws at the bottom front of the dryer, rotate the front to release it at the top. Remove the wires from the door status switch. Remove the 4 nuts holding the drum support frame and pull straight out. Remove the drum. Remove the two bolts holding the thermostat cover (silver odd shaped metal plate at the front of the dryer). Remove the dryer blower cover plate by removing the 6 bolts holding it to the blower housing. Remember to remove the bolt holding the plate to the bottom of the dryer. Release the door status wire from the clips on the left side of the dryer and set the blower housing plate to the right, out of your way without removing the wires. Remove the blower wheel by removing the Circlip at the front of the shaft and then removing the shaft compression clip. Pull out the blower wheel and then remove the rear Circlip from the motor shaft. The back of the blower housing can be removed by removing the 4 bolts holding it to the motor support frame to make access easier but this may not be necessary. Release the 5 wires attached to the motor. Release the front and back motor clips. I used a large straightblade scerwdriver to press down and out on the end of the clips. Lift out the motor. Remove the rear pulley from the motor using an allen wrench and transfer it to the new motor. Set the new motor in the support frame, ensuring the lips of the vibration isolation rings are pointed down to slip over the frame and are not facing up towards the clips ( makes clip instalaltion much easier). Hook up the wires, following the color coding on the motor controller you are attaching to. Reinstall the blower back housing if removed, rear circlip, blower wheel, front circlip, shaft compression clip, blower housing front cover (Including the bolt to the dryer bottom) , reroute the door switch wire up the left side, reinstall the thermostat cover, reinstall the drum and belt, reinstall the drum front support frame (ensure the felt seals for the drum and the blower cover are properly aligned and seated correctly), hook up the door status wire when your set the front cover and install the 2 screws, reinstall the belt through the pulley and idler wheel (make sure the belt smooth side is against the drum) through the back access panel and reinstall the panel.

Turned off breaker, then unplugged it anyway. I need some room to attack this old dog! Pulled out of its hole beside the washer and went to work. Opps, don't forget the flexible vent, I broke it off about a foot from the dryer. Four screws on back, lower right to remove acccess panel. Next two screws under front panel, pull bottom out about a foot and it unclips at top. Read the 5 repair stories about replacing the motor as I took everything apart, all were helpful. Had to put motor in a vise to loosen set screw on pulley, lucky I had a 3/16 allen socket, that was the only hard part, unless you count getting screws out from under the freezer where I kicked them. Be careful. Still ended up with belt in v-groove on back part of drum (where it does NOT go) so had to reach in from front and pull it out about 4 or 5 inches. Things a quiet now and I am a hero around here. Thanks for the good help fellows.

Summary: I followed the instructions in the PartSelect.com repair video that was displayed on the motor part page on the site (video here: https://youtu.be/eXJMmn5mwMY).

Details:
1.) I turned off power to the dryer.
2.) I removed the front panel by removing the two screws on the bottom edge with a stubby #2 Phillips screwdriver, then rotated the panel out until the clips released on the top edge.
3.) I noted the wire connections to the door switch, and then removed the three wires from the terminals on the door switch. I removed the door switch wire harness from the clips and moved it out of the way.
4.) I removed the blue wire from the dryness sensor and set it aside but left the other wire attached since it would come off with the bulkhead.
5.) I removed the front tumbler bulkhead by removing the four hex-head screws that secured it with a 5/16" nutdriver. I set the bulkhead aside.
6.) I reached back under the tumbler drum and slipped the drive belt off the idler pulley beside the motor, then pulled the tumbler drum straight out the front of the dryer. I also removed the belt as it was going to be replaced.
7.) I removed the two hex-head screws holding the guard plate over the temperature and thermal overload sensors with a 5/16" nutdriver and then removed the plate.
8.) I removed the single hex-head screw holding the blower housing to the base of the dryer with a 5/16" nutdriver, then removed the six hex-head screws on the front blower cover with a 3/16" nutdriver. I removed the front blower cover and set it aside.
9.) I removed the retaining ring holding the blower wheel from the blower shaft with a retaining ring pliers, then removed the spring clamp from the blower wheel hub with a pair of needlenose pliers. I used a flat-blade screwdriver to gently open up the slots on the blower wheel hub and was able to pull the blower wheel straight off the shaft.
10.) I removed the four hex-head screws attaching the rear blower housing to the motor mount with a 5/16" nutdriver, then removed the rear blower housing, making sure to gently remove it from the exhaust pipe as well.
11.) I detached the idler pulley spring from the idler pulley arm.
12.) I removed the two hex-head screws holding the motor mount to the base of the dryer with a 5/16" nutdriver, then slid the motor mount to the right do detach the tabs on the base from the mounting slots. I disconnected the wires from the motor (red, blue, grey, black and yellow) and moved the wiring harness out of the way..
13.) I pulled the motor and motor mount out of the dryer and placed them on the workbench. Then I removed the retaining ring from the blower end of the motor shaft with retaining ring pliers.
14.) I removed the drive pulley from the shaft with a 3/16" hex key to loosen the set screw. This required a few taps on the key with a hammer.
15.) I removed the motor clips from each end of the motor with a flat-bladed screwdriver, pushing the locking tab on the clip down until it disengaged from the hook on the motor mount.
16.) I removed the motor from the motor mount and discarded it.
17.) I placed the new motor into the motor mount and aligned it so that the frame of the motor would not come in contact with the tumbler drum. I put the new motor clips back on with a flat-bladed screwdriver.
18.) I slid the drive pulley onto the drive shaft and lined it up with the belt mark on the idler pulley. Then I tightened the set screw with a 3/16" hex key and several light taps with the hammer.
19.) I placed the rear blower retaining clip onto the blower end of the shaft with the retaining ring pliers.
20.) The motor came with no wiring diagram, and the manufacturer also changed the starting switch with a different model. Some research on the PartSelect.com site yielded instructions on the correct terminal connections. The motor came with several 1/8" crimp connectors to replace the original 1/4" connectors on 2 of the wires. I used the wire strippers to cut the ends off the red and yellow wires, stripped 1/4" of insulation, and the used the crimping tool to crimp new 1/8" connectors on the red and yellow wires.
21.) I replaced the motor mount and motor back in the dryer and connected the wires to the correct terminals. There was a blue jumper wire on the motor that I removed per instructions so that the grey wire could connect to the motor thermal overload terminal.
22.) Reassembly was then the reverse of disassembly. The only tricky part was putting the new belt on and getting it threaded through the drive pulley and idler pulley in the correct orientation. While I had the drum out, I took the opportunity to lubricate the drum roller wheel bearings and the idler pulley bearing and to clean out the accumulated lint from some 20 years of operation.

The job took about 2 hours total, a good portion of which was spent figuring out the correct wiring for the new motor.

The dryer now works quietly and starts without issue.

Removed the back - Saw the broken clips on the base of the dryer (the wires to the motor were pulling out because the motor was slipping).

Guessed that the parts were motor clips (no pix in the web site!)

Got the parts in post - they were identical except needed some rubber grips inside to hold tight (Used pieces of bike tire inner tube cut to fit for this.) Attached clips. Works fine!!
