Actually Dr.Bean came up with this kit about only five months ago. There must be more than ten M3 grinders in Taiwan and most of us had belt slipping problem. It screamed like hell. By the way, I'm one of the earliest owner and versalab provided the new bearings, a shim of newer version, and an inst...

After installing the toothed belt kit, my M3 grinder works well. It's not as beautiful as before, tho. {image} According to versalab, it requires the right torque to fasten some specific bolts and it's 100 lb-in for the pulley and 200 lb-in for the top plate. I've bought a torque wrench to have the ...
