Hi, we've just bought our first Kubota.. its a little old with no steering so we are trying to identify her and relevant parts. She was sold as a b1500 (we're in france btw) but the painted number on the bonnet has been painted over.. on the chassis it says b14 0708 kt and on the engine ks3 d89.. We need to service the steering so have removed the shaft and taken out the bearing from the base which is no NSK 15 BSWO2 .. Just giving you all the clues I have. Of course the bearings in the steering need to be replaced so I need to buy a kit so I have to be sure. The diameter of the shaft is 15mm ... We haven't been able to find a serial number anywhere..Help please?..
