Garth, the IPSCO idler assembly replaces the difficult-to-access nut on the rear of the OE idler assembly with a block of steel. The block has the appropriately sized threaded hole in it and fits snugly between the flanges on the back side of the bracket. As a result, the block won't turn, so it doesn't need to be held with a wrench when attempting to tighten the assembly (while holding tension on the belt). In essence, it reduces the number of hands required to do the job from three to two. If you don't already have it, you need it!
