WMD20LV Belt Drive
This belt drive is designed to be simple & compact, while retaining the quill drive function. The gears on the G0704 are VERY prone to stripping, with replacements needing a lengthy wait. This belt drive will make your machine quieter. You can also use the existing motor cover. This kit has parts in common with the Brushless motor version - so you can upgrade that motor at a later stage. You will need a new pulley & motor plate (available separately).
The pulleys are sized to give a 0.7 reduction on the standard motor - giving increased torque and limiting the max speed to about 4000rpm (based on 5600rpm stock motor speed).
New Quill & Spindle bearings are recommended for lower friction running:
Quill Drive: Replace with Nachi Shielded 6007ZZE & 6209ZZE.
R8/MT3 Spindle: Replace with 7007 & 7005 angular contact bearings (requires bearing spacer)
MT2 Spindle: Replace with 2x 7005 angular contact bearings (requires bearing spacer)
The belt drive should be compatible with the
