Good advice Clinton. I think I need to pull that drop gate. I'm always finding a lot of chaff in the front of the drum right before I do a roast at the beginning of the day. I've measured flow with the two fans and it's about double thru the drum with the faster fan on the roaster and the...
the old ym-2 had one thing that was much better, the cooling tray. They cost reduced the newer ones and so when you remove the plate to dump the coffee from the tray, the stirring vanes can't possibly force any coffee out. So you have brush it out around the stirring vanes. The older cooling...
So If you take that access plate off in the first picture and shine a light inside what do you see? On my newer YM-2, the flow from the drum comes out of that access plate port. The air is pulled from the perforations at the back of the drum, thru the coffee, up thru the top of the front plate...
I think you must have something like the 2004 version shown in this picture. I can see that the upper port is plugged like yours. Maybe this person can advise you? If you remove that cover and shine a light into that port you might be able to see right to the front. If you put some sort of...
Mine was built in 2009. There isn't a plate on the back of mine, there is a pipe that goes from the top of the drum to the larger port where you can see that diverter valve. You can also look into there and see the top of the blower. With the pipe in place, the blower sucks air from the...
I think you are right in your assumptions. The bigger motor allows you to cool and roast at the same time and gives you the option of more air flow thru the coffee to either enhance convection or slow the roast. At about the half throttle position I have the same flow thru the drum that I had...
This person supplied all of the ducts to my dimensions and I used Teflon seals in all the clamped joints HIGH TECH DUCT WERKS DUCTWERKS@aol.com
As you can see at my site, the cyclone sits on top of 5 gal can and all of that easily supports the cyclone and motor. I originally had some ceiling...

I can help you with that. I have to look it up at home tonight at home. It was about $160. and is a drop in replacement. This is where I bought it:
It's one of these from this company. It might be the first one but it's 3450 rpm, 1 phase....you have to get the right one so it has the right...
Yeah you have to really love it. I met a young farmer in Kona that quit his "game programming" job one day with a yellow post it that said I quit. I was pretty inspired by him but it's a huge commitment for sure and lots back breaking work unless you can afford to hire help. And still the...
Yeah 3.75 lbs works out perfect for 3 lbs net for most of my roasts. I've found that roasts with a lot of chaff or large beans don't do very well at 5 lbs, although it is possible to roast 5 lbs at a time. I've never had any uneven roasting issues. You just seem to have more control and...
Sorry so late on this reply. I have one of these, a 2009 model. you can roast in 5 lb lots with some beans. The AA's, sumatras, etc are better roasted at 4 lbs. In general 4 lbs is the sort of sweet spot on the this roaster. The drum is not overly large in my opinion relative to the burners...
You should also consider the IR5 (used be IR7) Diedrich. It is heavy at 998 lbs or so. The price was pretty resonable too when they showed it at the SCAA show recently. And the USR 3 Kg is said to be able to roast 10 lbs at a time and it's even less than the IR5. Debbiej just bought one of...
