This is an original cast iron idler pulley with mounting arbor for a hit and miss gas sawrig engine or other piece of machinery. It is in excellent condition with no cracks, breaks, or repairs that I can see or know of. It measures about 5 inches in diameter with a 6 inch face. It mounts with two holes in the bracket and could easily be used not only as an idler pulley but also as a tensioner for the belt with a couple slotted holes. The pulley moves smoothly and has minimal wear in the bearing. These idler pulleys are extremely difficult to find in the wild or even at swap meets so if you’ve been looking for one to complete a restoration here’s your chance. This one should be ready to be put to work on an engine or put into your inventory for a spare. The pictures tell the story. You’ll like it. I can be reached at 262 573 193 1 if you’d like to talk about it.
