I’ve just done my first deep clean after around 30–40 roasts. Since cleaning and reassembling, I’ve had a noise that appears to be coming from the front of the roaster.
On initial reassembly, the front bearing wasn’t seated correctly. I powered the machine on briefly before realising (lesson learned). I then corrected this by lifting the shaft from inside so it was properly seated. It roasted fine for a few batches after that, but would occasionally develop a noise, which could be temporarily resolved by gently pushing the shaft from the front while it was turning.
After reading various posts here and on Reddit, I’ve concluded this is likely a front bearing issue, so I’ve ordered a replacement and am awaiting delivery.
One question I’m hoping to clarify:
When watching cleaning/maintenance videos, I’ve noticed washers or shims behind the front bearing. As far as I’m aware, my machine did not have any. There’s a chance one may have fallen out during cleaning without me noticing, but I’m fairly confident there was no washer present.
Is that normal? Should there be a washer/shim behind the front bearing?
Update: Changed the front bearing. Nothing. Turned the machine on without the chaff collector on - i can hear that the noise is in fact from the rear of the machine. The wear pulley is not, however, chafing.
It’s usually this, but you never know. If that doesn’t work, we’ll see. The pulley might be making contact in the back because it’s not pushed all the way in.
Thanks for commenting - it’s sorted now. I had done this but i was confused because i could see that the back pulley wasn’t chafing. I ended up taking the faceplate off, pulling it forward by hand, then re-positioning the faceplate. I also ended up adding the 2 shims/washer provided in the kit, because all maintenance videos i watched showed them to be present behind the bearing - so i figured i must have lost the previous washers whilst doing maintenance.
Anyway, all sorted and back roasting again now. Thanks for taking the time to comment.
