Speed Queen electric dryer drum for Model NE5513W
« on: November 03, 2020, 03:35:57 PM »

I am currently involved with repair of this older unit. It is probably at least 25 years old and runs well considering its age.  The drum has a slight bump when it rotates  which I am sure is due to a weld joint where the drum is rolled and welded during the mfg process.  I have asked the factory for a spec on the overall variation  they allow on the drum diameter. This is commonly referred to as TIR (total indicator reading). They did not have a number and I dont know if it would mean much since I dont have a setup to measure it anyhow. My question to other techs is when you get a drum that has  slight bump during rotation what if anyting do you do about it ?  This is not the 1st time I have seen it in dryer drums that are made of thin sheet metal.

Today I worked on a couple of Maytag dryers of an older vintage with model numbers LDG512 and LDG7400AAL. The drums were checked  when i removed them and it looks like these drums were made  of  slightly heavier metal than the previous model  I mentioned. With this material it appears that the factory was able to make the drum more concentric and the weld seam less likely to have a bump at the weld seam. The newer units are more likely to have the bump problem as compared to the older designs.

As of this date, the factory does not have a spec they can provide for the T.I.R. (total indicator reading) and suggest that if a drum has a significant bump to it when passing over the support rollers it should be replaced.

If the drum is symmetrical, maybe rotate and reinstall to see if it runs smoother.  Front sliders have a wider contact area than the rear rollers and may tolerate the drum's bump.

I have on occasion reversed the drum and it sometimes improves the bump. If i is really pronounced I have also considered using a filler material to reduce the bump but not sure if the material would stay in place due to flexing of the drum and heat.
