And then you really screwed up when you backordered it and gave me time to check it out. 

Duo-cone seal for idler wheel on quadtrac.....CIH price, $140, backorder, delivery date unknown.  Measure and cross  to Caterpillar...price, $35, presume it is on the shelf....cross to aftermarket Cat supplier, price $9.83.  Caterpillar builds their own, and it might  be better then aftermarket.  I'm betting you do not build yours. 

I'll give you a little markup, but 1324% markup is a little much for me to stomach today.
