Toothed Drive Belts for Oil & Water Pumps
We carry a wide selection of toothed belts for Formula Ford 1600, FF2000/Sports 2000, and SCCA Formula Enterprises cars.
L & XL numbers:
The string of numbers with L or XL in the middle are industry-standard identification numbers printed on the belt.
L and XL indicate the tooth pitch, measured from tooth center to tooth center. L belts (Light) have a 0.375" pitch. XL belts (Extra Light) have a 0.20" pitch.
The first three digits indicate the belt length in tenths of an inch (e.g., 190 = 19.0 inches).
The last three numbers indicate the belt width in hundredths of an inch (e.g., 050 = 1/2 inch).
So a 190XL050 belt will be 19.0 inches long and 1/2 inch wide with a 0.20" pitch.
If the original belt is missing, you can wrap a string around the pulleys to find the length required. Do not stretch the string tightly, but do not let it droop. Mark the string and measure its length.
