@JimP2014, what is your goal here? Do you want to "fix it right" and keep this mower working for another 10 yrs? Or do you want to just get it fixed enough to work for now, with plans to run it until it dies? I understand each position. It may not be worth it to "fix it right". If you DO want to fix it right, you have more work to do. The pulleys still aren't right.
Pulleys should:
- Not wobble.
- Not have much vertical play.
- Spin freely without excessive noise. They will make some noise, but they shouldn't be loud.
The tensioner arm shouldn't have play in it either. With the deck engaged, the belt should ride close to the middle of the idler pulleys. The belt should not ride against the edge of any of the idler pulleys. Belts should not get warm if the blades aren't mowing any grass. If you're wanting to keep this thing for a while, I would fix these things before getting wound up over belt lengths & widths. If you just want to get through this season, let 'er rip.
