    I think you will find they are actually an "M" section belt not a "A" section.

    I think you may be right, just looked at a similar Grizzly lathe and it uses a M24 belt.

    Might put the M23 belt back on till I get to the bottom of this, don't know whether the A22 belt will do any harm.

    Anybody know the difference between A and M type belts, I assume it is the profile?

    Default A Belt Across the Ear ...

    Sorry if I gave you a bum steer on the A22 belt, BS - now you've got me keen to find out which would be the best fit. The belts on my lathe so far have just been the el cheapo ones supplied by CarbaTec, and they have no code markings at all. They wear out rapidly, although I have had much longer service from mine since I disassembled the pulleys (carefully!) and polished the inner faces with wet&dry then metal polish to remove all the machining marks, etc which contribute to wear.

    Surely someone amongst our fellow forumites has the engineering know-how to set us straight...

    Hey, no problem, only cost $5.20. It still works, but instead of riding high on the motor pulley it rides high on the headstock spindle pulley. It is certainly a very solid and substantial belt.

    Have been searching the web, but can't find any references to either the specified belt for MC900 or specs for the M23 and A22.

    I preferred the A22 because the lathe ran slightly slower with it which was better for larger items and I never turned at the top end anyway
