I know this question has probably already been answered here, but I searched and did not find it. Can anyone tell me the belt size for my Atlas 101-27430 lathe? I mean the motor-to-countershaft belt.

Found it.... the motor belt is size 4L350. I was not creative enough with my search.

OK. AFAIK, that's correct. And the spindle belt would be a 4L310.

Just to add closure to this thread... I got a Goodyear/Contitech 4L350 belt. It is about 2 inches shorter than the belt that I had been using, but it seems to fit the lathe better - the motor is now tilted up slightly - near the mid-range of the motor's belt-tension adjustment slot. And the belt fits the sheaves of the motor and counter-shaft pulleys well.

Just for information to find v-Belt: 3l is for 3/8'' wide pulley and 4l is for 1/2'' wide pulley. 350 is for belt 35'' circumference. Like for a pulley of 3/8 and cirumference of 26'' we obtain 3L260
