Samsung DC97-16782A Dryer Drum Support Roller Assembly OEM Part

I first researched on AppliancePartsPros.com the availability of parts. It looked like all common parts were in stock ready to ship. I also found that APP had several helpful videos to show how to take apart the dryer and replace the parts. Other research indicated the most common problem is the drum rollers, but after seeing the videos I determined that not only the rollers but also the tensioner pulley could be bad and the belt too. So I bought all of these parts because I did not want to take the dryer apart and not have every possible part. The tensioner pulley was the main part that was bad, the bearings were very loose and making noises. But as I checked the drum rollers, 3 of them were not turning as freely as a new one. So I am glad I had the extra parts. So for anyone out there with a similar issue I would recommend just replacing all the drum rollers, the tensioner pulley and the belt. After I finished my dryer runs like new. The videos said the job would be less than 2 hours, which normally it would be but with the dryer completely torn down, why not clean every possible area and part you can. So the job took closer to 4 hours with cleaning. One final note, from the factory I noticed that the plate the tensioner pulley is attached to is connected with a shoulder bolt to allow the plate to move freely with spring tension. This is all correct, but the plate to plate interface where the shoulder bolt is had a lot of wear marks and a lot of metal shavings under it. Also, the tensioner plate did not rotate very freely. I suspect that after years of service, that plate caused the wear and thus over time became less and less free to move. This probably eventually led to additional stresses on the bearings because more tension from the belt was being put on the pulley. After installing the new belt I noticed the old belt was quite stretched out. So, My final recommendation is to put a dab of high temperature grease on the tensioner plate so that it will have less metal to metal wearing.

Located the defective roller. There are four and the right rear was shot.

I disassembled the dryer following the video on the site. Each of the wheels (4) had a flat spot on them and the belt was frayed on the edges. I replaced the guide wheels and was about to install the belt when I noticed that the idler had been cut through by the belt. I had to purchase an idler locally and then reversed my steps to reinstall the components of the dryer. One big bonus of this job is that I cleaned all the accumulated lint from the fan and duct and now my dryer works better than ever. I think I might see an improvement on my hydro bill because of the reduced drying time.

AppliancePartsPros.com video on taking apart my dryer and replacing idler pulley really helped me out. THANKS GUYS

The noise was a major issue as it proceeded to get worse. After reading the potential causes, I viewed the video on the appliance parts web site on how to repair the rollers.(this was the #1 reason people reported the noise). The video was very clear and looked fairly simple. The unit needs to be taken apart which is well detailed in the video. It looks daunting, however it is actually very straightforward and not difficult. It requires a phillips head screw to remove the outer unit and control panel. The rollers utilize a wretch and a socket. I replaced the belt and idler wheel while in there as it is easier to do everything at once. Overall 45 minutes, add 20 for cleaning all areas for lint
