Engine housing question
I purchased a Craftsman 919.762500 pressure washer. I am going to try to get
it running, but there is something I need to identify before I start. Between the pump and the motor there is a small hole in the top of the housing. I have no idea what it is for. Can anyone provide any information? The image is taken looking down. https://www.homeownershub.com/img/j1 |

A small one to the left of the center of the picture, and a larger one to the right of center (closer to the cooling fins). I'm thinking you mean the larger hole. Is either hole tapped (do they have threads) ? The space behind the larger hole just looks to be where the drive shaft is exiting the motor and entering the pump and I wouldn't think it's used for anything. |

It is a "weeper" hole - lets water out from between engine and pump if a pump seal fails |

Some designs are totally open with legs connecting the 2. |
