Idler pulley came off while I was mowing; after inspecting it I found the bearings had gone out. So I went to ereplacementparts.com and found all the components I would need to replace it.

1. I placed the mower on a ramp so I could easily get underneath it to work.
2. Dropped the mower deck all the way down to it's lowest position.
3. Installed the new pulley with Hex bolt, flat washers and Hex Flange nut. This only required the use of a 9/16 combination wrench and a 9/16 ratchet wrench.
4. Replaced the belt and the mower was back in operation.

Removing the old steering parts was no difficult. Getting some parts was a bit tight behind the engine. Had the tractor on jack stands so I could get under it. Downloaded the parts diagram and used it to reinstall the parts once they arrived. Centered the front wheels and steering wheel, tightened all parts and finished.
