Samsung DV56H9100GW/A2 dryer lubrication after repair?

[dochawk]

At last I have this thing running without banging . . .

 

We stopped using it when we noticed the banging.  After initially focusing on the cracked drum, we found the belt had a melt across all the groves, and then it still banged when reassembled.

 

More poking suggested that the tensioner spring wasn't strong enough, and we tried to replace with one from  off the shelf at Lowes--which couldn't extend far enough.

 

After sitting on the porch for a year and a half . . .

While ordering another part, it occurred to me to look for the exact spring while I was at it.  Surprisingly, Amazon delivered it the next day (but didn't bother to knock, so it got put off until daylight today).

Anothger round of reassembly, and it no longer bangs on the sides.  However, it's still far noises than it was:

 

And it still wobbles, but not like it used to.  But it's noisy, which I assume means excess friction.

 

What should I do to lubricate it?

 

Here it is again with the top on, and still too loud:

 

 

I assume that it needs to be lubricated in some manner?

So close, and yet so far . . . 

thanks

The drum is what we called Out of Round when I worked in the tire business. How did you resolve the cracked drum? Did you replace the whole tensioner assembly? What do the drum support wheels look like? So many questions...

Incidentally... I use either powdered graphite or synthetic grease designed for high temperature, infrequent changing. I try to avoid using grease tho because it attracts dirt.

After waiting several months for the supposedly in-stock replacement drum to actually get shipped from Korea, and then installing it, I mentioned it in passing to a friend who turned out to not only be a welder, but actually able to do stainless.  He welded the cracks.  In any event, the new one, over $300, drum wobbled *exactly* like the original and was set back.  

 

The pulley and the tension spring were both replaced, but not the arm.   The new spring is the difference between the drum rubbing on the sides. of the machine as it precesses, and not.

 

The support wheels showed no visible wear--I wasn't specifically looking to inspect them, but I've seen them up close *so* many times at this point . . . 

 

Where would I apply graphite?

 

thanks

I would apply a brand new old-style Whirlpool dryer that you can get on sale for about $400.
