In search of a dedicated small engine community I come here.
I have an older husqvarna frontrider with a hydrostatic transmission. While checking the transmission oil I noticed that the fan had broken of most of the blades.
Looking at the transmission cover I can see that it has been grazed by the blades, suggesting that the fan has been pulled sideways.
The oil check was part of a small service, that I was doing since I had to replace both belts going to the cutting deck as well as the belt in the deck. Those belts died when the belt tensioner, in middle of the mower, came loose and dangled beneath the mower.
My questions are these:
- WTF?
- If the belts have pulled that much in the engine driveshaft, as to do this, what else would you look for before starting the mower again?
- Given that it’s about 10°C outside, would you run the mower without a fully functioning fan?
- Have I missed something? Any wisdom you wish to impart?
Is there any play in the fan when you take the belt off?
I’ll have to investigate that, but there wasn’t any play with the belt on.
Could you have possibly run over some brush that could have made it’s way into the engine compartment?
Maybe, but that fan sits pretty well protected. The only two things I can come up with is either something got on top of the cover and forced it down, which doesn’t seem likely as there’s almost no space there, or the fan shaft got pulled so much that the blades hit the cover. Neither scenario seems likely, so that’s why I’m at a loss.
But seeing as a local reseller has the part in store, I guess that it has happened before.
