This is a 65 ford 4000 tractor 4 cyl. Has a ROOSA MASTER pump model #DBGVCC429 and i need a brekdown diagram of the pump. It belongs to a friend of mine and i am supposed to know how to get it back together and all of my expertice is with DATSUN NISSAN Z cars, 36 years worth. By the way, he took it apart. If anybody can help, i would really appreciate it. I have a low mileage(75000) 97 3500 and its real chery. Lots of DG products and i pull a 30 ft RAGEN toy hauler. And i run with the big boys. I can prety much stay in over drive. I ride a DS650 And a PRARIE. When they are not on top of me. Right now i am healed up again. I drove over the road when i was much younger. 14 years worth, last 4 years pulling 2 trailers. Spent a lot of seat time in EMERYVILES, WHITES,MACKS, even drove a KW HALF SHACK.
