This pertains strictly to a Maytag model LDE7600, new in September, 1990. In service ever since.
After watching How-To videos presented by Appliance Parts Pros, I decided to tackle the repair. I ordered a new belt, two new drum support roller wheels, and two new tumbler slide bearing kits. Parts arrived the next day!
For this model I found it necessary to remove the front panel, top, and front shroud. all easy to get to. I also disconnected and removed the control panel. Marked each wire color next to it's pin with a felt tip maker. Then I could put the top out of the way. Finally, very easy to lift out the tumbler drum and set aside. Got out the shop vac and cleaned 27 years of lint.
Removed drum support roller retainer using retainer pliers, piece of cake! Fit new rollers in a matter of minutes. Drilled out old pop rivets from the slide bearings, and popped in new sliders. Really needed to be done.
Wrapped the belt around the tumbler, used the belt as a strap to re-position the tumbler into the machine. Attached the front shroud.
For this model I believe one MUST use the rear access door to position the belt onto the motor and idler roller. Since I'm old and decrepit, I needed to use a wedge block and long screw driver to back off idler spring tension. But, not too hard with the long lever.
Replaced the top, wired up the control panel, and attached door switch wires to the still off door panel. Plugged her in, and she run better than new.
For this model I believe it was much easier to remove the top and control panel than to try to work around them. And, I suggest that if you'er going to replace the belt, it makes perfect sense to also replace the rollers and slide bearing at the same time. One thing I didn't do, but should have, is to also replace the worn out rubber cups on the bottom of the four screw leg levelers.
