I just finished fixing (I hope) a drum roller that was seized up. I found a few you-tube videos that were very helpful. They all showed how to replace the rollers. When I removed the old roller, however, I noticed there was no ball bearings on it, just a steel bushing. When I cleaned up the shaft and roller bore with varsol, they were both in very good shape. So I put some oil on the bushing (now I wish I would have used grease) and put it back on, and it seems to run fine. I am wondering if it is good for another 10 years, or if I will be doing this again soon because I should have replaced the roller. For those of you familiar with dryer repairs, what do you think ?
