The driveshaft that drives the injection pump? The injection pump on this engine is driven by a cam that pushes little plungers on the bottom of the pump.
Fuel goes in the side and comes out the hard metal lines on the top. I thought maybe the seal on the one of the plungers was broken, but I have no way to check it. So I thought I'd get it running again and see if the crankcase fills up again. I already put a new fuel pump on it, so if I have the same problem, then I have a leaky injection pump right? I can't find a diesel pump shop on Maui. There's probably one on Oahu, but I haven't been able to find it. Do you know of a good shop on the mainland somewhere that is familar with the Kubota pumps? I can send the pump there for $8.05, have them check it out and send it back to me for the same price. The Kubota dealer here said they rarely have a problem with the Kubota pumps and when they do, they just replace them with new ones. Please let me know. Thanks! George
