What to bring / what we need to match it
- For a belt: the old one, or the profile letter (A, B, C, 3L, 4L, 5L, and so on) and length stamped on it.
- For chain: the pitch, number of strands, and length in pins or feet.
- For a sheave, pulley, sprocket, or coupling: the bore diameter and tooth or groove count, or the part in hand.
- For a gearbox or motor: the nameplate — ratio, frame size, horsepower, and mounting.
