I am just a few weeks into my rock tumbling experience after buying my daughter a Lortone 33B for Christmas. My question/concern for today is this… will the nylon washer (on the opposite end of the motor) eventually wear out due to the constant rubbing from the barrel's washer? It is secured by a rivet, not a screw. If and when it does wear down, how would I replace it? Thanks for any info/advice in advance!
I tried attaching a pic, but it kept telling me the file was too big. Any help with that would also be appreciated!
Thanks, John

I've had my 33B running for four years straight. At first, I used to try to level it so it wouldn't rub against the end, but it was almost impossible to do so. Now it always runs against the white washer. It's worn some, but not as bad as you'd think. I have rotated it once in a great while for more even wear. I wouldn't worry about it. If I had to replace it, I think I could drill the rivet out and replace it with a bolt. The wear that I'd be more concerned with is the nylon washers. Mine wore out and I had to replace them. The frame actually wore through the shafts, so those had to be replaced too. I'd check the nylon bearings in about a year. Thread about my worn out bearings

I have two 33b's, both "retired" now for larger tumblers. To the point ... I ran mine for three plus years and although the nylon washer is worn it is still serviceable.
If one had to be replaced the rivet would have to be drilled out.

Last year the nylon washers on my Lortone 33b had worn out to the point that the barrel lid washers were almost rubbing the frame. I purchased a few nylon washers at a local hardware store, drilled out the rivets holding the old washers and installed the new ones using small screws and nuts. Veery easy and inexpensive to do. Also, a tiny bit of sewing machine oil on the nylon washers helps reduce friction and wear. My 33b is still running strong after over 20 years.
