Does anyone know if the D shaft motor is an actual upgrade. The set screw failed on mine and I have the older non-D motor but I need to buy a new pulley and set screw as my old set screw essentially disintegrated and seized to the old one. I also found some metal debris on top of the motor but I think its ok. Is it worth getting the new D motor and pulley or should I just get another pulley for my current motor?

I will be able to tell you by the end of the week.

My gut says yes. The helix shaft on the old motors is garbage.
The D-shaft should spin true and virtually eliminate belt wobble. The drive sprocket is often offset on the helix shaft and wobbles to and fro .050-.060" at times!

Cheers!

Ya I bought mine used and the Burrs have been taco'd before as they have some marks on the edges. The grinder was working great and I aligned it reasonably well and it ground well for my pour overs but then I adjusted for espresso and the set screw gave out. The motor just spun up like crazy so I took it apart and tightened the set screw and it gave up again. Probably because it was already damaged. On top of that the stop button on my screen stopped working after the last time I took it apart so now Im debating on buying everything new and overhauling the grinder (New motor, new screen, new burrs)

With all that plus an unknown history, it might work out easiest to send the grinder back to Baratza for their fixed-price repair program, which includes parts (except new burrs). You can get new burrs installed at the same time. I believe that you can also buy the Forté grind chamber at the same time and have it fitted - that's what I did.

The drive sprocket should fail before the helical shaft. Something has to be the weak point when rocks enter the grind chamber, and it should be the least-expensive part - the drive sprocket.

I'm not too worried about taking it apart as I have already done so a few times and the grinder was working great before hand. I have had it for a few years now so even though it has an unknown history, its been pretty solid for me up until now. I never really used it for espresso and the beans were a pretty light roast so I think that caused the set screw to fail. Even after tightening it previously, it worked fine for my pour overs until I tried espresso again. The extra resistance from trying to grind fine just pushed it over the edge and I figure if I'm gonna start replacing things I may as well do it all. The grinder is a great and built like a tank and its size is small enough that I don't really see myself getting rid of it soon. Also, it is a Forte BG so I already have the forte grind chamber and other parts. The helical shaft looks fine, as does the drive sprocket, but the set screw is seized and I cannot get it out. It has been ground smooth by the helical shaft and won't allow me to turn it out of the drive sprocket.

I was just thinking a new display and a new motor would be $80, and the repair program is $90. However, if there is nothing wrong with the motor, then it won't be replaced of course.

Carry on :wink: .
