I just picked up a Craftsman 103.2262 10" vintage floor model saw from Craigslist. I noticed that the 113.19092 1HP motor has 3 pulleys on it and so does the arbor. At first I though maybe they were for different speeds but they all look the same size so I found the operating instructions manual online and it says that this saw used a matching set of 3 v-belts and they should be replaced as a set. I can't find any reference to this anywhere online. The part number is 197-X-1470 and the description is "Set of 3 v-belts 3/8 X 48". When I look online for a 3/8 X 48 belt I come up with 2 options. 1- 3L480 v-belt 3/8×48, and 2- 5L480 v-belt 3/8×48. Does anyone know the difference between the 3L480 and 5L480? and which one I might need? Also does anyone have any info on the 3 belt set? When I picked the saw up it only has 1 belt on it now. Thanks in advance for any help.
3/8" X 48" should be a 3L480. 3L = 3/8" wide, 4L = 1/2" wide, 5L = 5/8" wide. And belts are made to much closer tolerances than they were back in the day, so a strict 'matched' set is not really needed IMO as long as you go with a quality manufacturer (ie: GoodYear, Gates, etc…). One gotcha though - it is not specified if the 48" is the inside or outside measurement… I would measure the belt you have to make sure what size you need.
I used to flip a lot of the older Craftsman contractors. Toward the end, if the belts looked too worn, I'd swap them out for the red link belts. They seemed to really smooth out those saws. Putting new rubber on one, seemed like you created a paint mixer.
TherealSteveN thanks for your response. I now have to decide if I want to go with 3 standard v-belts or maybe just 1 linked belt. Some have told me that the 1 belt might be safer because it would be more likely to slip in a bind versus the 3 belts.
