    Bomag 172 roller issue

    I have an 86 172ad single drum bomag roller. I have a hydraulic leak coming from the vibratory drum pump just inside the frame rail. I can't see where it's coming from and I don't know what kind of pump it is. The bomag manual doesn't have any pump information. Any help?

    Parking brake won't release
