The hell were they thinking? Part 2. This job sucked. Presented as non-moving, with the cause found as a broken hydro belt. But what caused the belt to break? Maybe the toasted V idler. Skipping over the semi-impossibility of access to the clutch connector, anchor and tension spring, and complete lack of room to get a hand or slip the belt in place...let's just look at a couple things.
Firstly, the failed idler pulley is not aligned with the hydro drive pullies - it sits significantly higher up so that the belt is pulling on it at an angle. It's hard to see in the picture. Look at the bearing in the pulley body- it failed and moved to that angle. I checked the IPL and there were no missing spacers, etc. I had 1/2" of extra bolt length to play with so I added an extra nut and washer to make the belt alignment straight.
Secondly. When re-assembled- with all factory parts- the belt almost rides inside the other side of the V pulley, even under maximum tension. A little slack and contact and...belt time.
Third, all of this was compounded by the fact that the IPL diagram is terrible. The engine pan and belt in the diagram are shown from two different perspectives so as you look at the pan it shows the belt routing backwards to what it needs to be, which wasted LOTS of time.
Equipment: Ariens Ikon XD 42" zero turn, previous generation.
