Looking at a 49 1/2 ton with a 235 high pressure engine. Trying to identify engine. I don't see a casting number on the RH side by the 3 threaded holes. There are some stamping numbers on the machined area 0269382 and then F547. I need a water pump and it looks like it is the style with a plate on the back of the pump, which is kind of like the 216 engine. If so, will the 216 pump work?
