Hi,
I've done a bit of searching, but haven't found any old threads about Thumler motors. I have an AR1, 3lb rotary tumbler. The motor is making a lot more noise - I had stopped it to recharge a load 2 days ago and tried to start it up last night.
It makes the noise even when the drive shaft and belt are removed.
The load I was going to re-start is about 4 lbs, rocks and water and barrel....
Wait a minute. Did I just say I was running 4 lbs on my 3 lb tumbler??!! I think I just found my problem.
But what can I do about the motor? The noise goes away (or greatly reduces) if I pick up the whole frame and point the drive shaft towards the ground. It gets worse if I point the drive shaft to the sky.
The tumbler was new last August, and I have oiled the motor with one drop in each port (there are 2) every month or so. Maybe every 2 months.
Can I take it apart and repair or is it too late? How do I get the motor casing open? I've never tried to remove anything like those strange clips. What am I looking for once I get inside?
In the future, I need to change how I compile my loads. My tumbler doesn't seem much more than 2/3 full, but I do have a lot of small pieces in there, to help distribute the grit. Maybe too many, if that volume weighs that much?
Any help is greatly appreciated!
