mower engine blowout again
Must be something in the air... following the 'mower engine blowout' thread a few weeks ago, my trusty ol' mid-'80s B&S lawn tractor engine decided to call it quits yesterday: http://www.patooie.com/temp/eng.jpg Upon initial inspection the valvegear and crank seem to have escaped damage, so I think the failure was limited to the balance weights (with a bit of collateral damage due to things bouncing around inside the crankcase) cheers Jules |

Bother, that looks like a total catastrophic failure.
Closest I've had, was a generator that threw a rod. But, mine was enought to result in some very out of character crude language, as I realized my mistake. Oh, well. Christopher A.

I noticed that the old Briggs push mowers with 2 to 5 HP engines will last forever, even if they are not kept up properly, but the larger Briggs engines are notorious for blowing rods, no matter how well you care for them. Of course that includes all the lawn tractors because they all have at least 8hp engines, often up to 20hp. |

The root failure seems to be the hole for the oil slinger bracket wearing and elongating - that meant the oil slinger teeth were no longer meshing with the drive gear properly. The fragments of the top support and bearing for the synchro balance weights show signs of major overheat, presumably due to oil starvation. One that support failed, the lower support couldn't handle the load by itself and quickly failed too - this left the weights flapping around, and which point the crank collided with them and threw them out of the engine... cheers Jules |
