Airdog 150 shaft seal
 

Long story short, I Pissed up the seal robbing the motor off a new 150 I had on the shelf. Turns out the motor was fine anyway. But I looked at the seal and thought I could do better. Measured it up and ordered up a replacement dual lip SKF seal from McMaster Carr. Had it here the next day. And it fits like a glove. Won't be using this pump for awhile but just thought I'd share with you guys the part number for "hopefully" a better seal. And it is rated for 50psi also. Here's some pics.
