My 2000 tracker 2.0 idler pulley failed the bearing seized and started spinning on the shaft eating through the shaft part of the way I have every thing off for a timing chain replacement (different problem) but I can not figure out what this shaft is called or a part number for it the Suzuki dealer said its the idler gear shaft but I believe they are wrong if anyone knows please help me

 

It should be the the idler assembly, which in my 91 comes all together.
