I have a David Brown 990 and I need a water pump for it, I think. There are a lot of different ones avaliable for this tractor and I am not sure which one is correct. They all look similar, just have different numbers. I just got this tractor and would like to fix the few minor mechanical problems it has. It belonged to my stepdad's dad since the late 60s. It has 5400 hrs on it. The engine was overhauled just before 5000. It runs great with no smoke. It aint real pretty, but it is in great mechanical shape. So far what I have been able to figure out is that it is a 1964 model 990 Implamatic. Here is all the info I can get off of tags on the tractor.
Tractor Model - 990/UA
Serial - 468090
Engine Model - AD4 47A
Serial - 50063
Loader Model - AL2
Serial - 17598
If anyone can give me any information on this machine I would greatly appreciate it. The manuals are being searched for and I will get them before long. I just don't want to wait til then to start working on it. The water pump pulley wabbles when it is running. There is no leak from the front of the pump and the radiator is full. This might be able to be fixed without replacing the pump, but I don't know.
