Standard replacement Myford Super 7 and ML7-R motor drive belt.
This belt drives on the left-hand side of the lathe from the twin stepped motor pulley up to the large countershaft pulley/clutch pulley.

If you're experiencing vibration from the standard belt we also sell a Fenner Link belt which will help to reduce the vibrations which the Super 7 is prone to, especially at higher speeds.
The link belt can be found in the 'related products' below.
