Hello, I am new to this site. I am a volunteer at Dallas Fire & EMS in Dallas Oregon. We have a 1924 Stutz Bearcat Fire apparatus that was our first motorized fire apparatus. It runs great, still pumps water great! Our clutch is in need of repair. We have removed the pump assembly, and the transmission but can not see how to remove the clutch pack from the transmission to have it relined. The transmission is a Fuller & Sons mfg. co. Model GU-7 S/N 133950. Any help would be greatly appreciated!!
