Whirlpool WP6-3700340 Belt Tension Pulley OEM Part

I replaced the belt, belt tension pulley, both dryer drum roller axles and both drum support rollers. Although I bought 2 tumbler bearing kits, because those still look good I am saving them for when they go bad. The videos were fantastic! I also took pictures as I went of wiring so there would be no question where things went when reassembling. It should be noted some models have extra terminals near the sensor terminals... just be aware and look closely/take pics as you are taking things apart. I did purchase a split ring tool half way through the job to remove the split rings after fiddling with a flat screwdriver. It was well worth it and took literally seconds to remove and later replace the rings! I used a spin handle with sockets instead of nut drivers and it worked fine. The right rear drum support and axle appeared to have been the problem; the axle was darkened, the roller was more yellowed, and the nut was very difficult to loosen - all consistent with having been overheated. The belt tension pulley does not come with washers so be sure to save the two to reuse if you are replacing this part. Also if you suspect your problem is coming from the pulley you might consider buying the idler pulley arm that comes with the shaft permanently mounted to it. Mine looked fine and I did not replace it. All in all the job was very simple because of the videos that showed where all the clips were and the order of disassembly and reassembly. I am a smaller woman and the only thing I needed help with was to get the right rear drum roller axle loosened. Had I been alone I would have had to tried to fit a cheater bar on the end of my wrench handle which would have been a challenge due to the tight working quarters on that side. I was able to easily do everything else by myself.

I replaced drum rollers, axle shafts and front bearing kit. Still had noise. Ordered Idler Arm, Belt Tension Pulley & Washers. I ordered parts at 3:30 pm on a Wednesday, received new parts at 11:30 am Thursday. The instructions & videos were very simple to follow and provided excellent tips. Back up and running with silence in an 1/2 hour. My 13 year old dryer is running like new again. Way cheaper than calling a repairman.

Watched a Youtube video on how to take my 15 year old Maytag Neptune dryer apart. Found the belt tension pulley badly worn and squeaking. Decided to also replace the drum support roller while I had it all taken apart. Replaced pulley and rollers and used graphite to lube all three. Worked perfectly.

First replaced the drum rollers...that wasn't it..took dryer back apart and spun the belt tension wheel by hand (should have done this the first time I took the dryer apart) and it squeaked. so I ordered the full parts: wheel, idler arm, idler spring, arm sleeve, E ring..Put it back together and whoa..no more squealing!!

Ordered idler pulley, new belt and 2 tub rollers. Everything matched, fit good, Dryer working good, no squel.
