Panhandle Bob posted:Would damage to the fan blades be from stuff getting sucked into the shroud or is there something else, like bearings wearing out that would cause that?
Nope.
The fan wheel flies apart because unwelded, unbalanced, unaligned fan wheels of all types tend to blow apart when they exceed their design RPM. Carrier package HVAC units are notorious for doing this. When they go, it's pretty manly-- shrapnel everywhere
...unfortunately, it's the same deal with a VW Type 1 (only the parts are heavier).'
Get a welded/balanced fan-- for the children.
Mike-
Really, really sorry man. I'm pretty sure there is zero difference between the EMPI and Scat 36 hp doghouse shrouds. I'd bet a latte that they come from the same place. This is one of the EMPI parts that has nothing wrong with it.
If it were me, I'd get the full-meal deal: shroud, welded/balanced fan, backing plate, alternator, stand, and a pair of cylinder tins, just to be safe. Hopefully, the cylinder and head fins are OK.
