My son and I are trying to restore a1977 B6000. After installing new glow plugs and injectors/nozzles my son found beneath the tractor a small tubular part which is described below. I queried SD Vic of OTT, but he indicated that he had never seen such a part associated with a Kubota injection system. I would appreciate any information from anyone about this part and its function. I will try to attach a photo.
Part of our renovation involved new glow plugs, new nozzles and nozzle holder assemblies. We did not disassemble any part of the injection pump itself. After the injector work my son found in a fold of the tarp upon which the tractor is parked an unidentified part - it is tube-like, but not hollow (no lumen), length 28 mm, diameter 4.9 mm. Distributed evenly around its circumference are 4 shallow, linear grooves or scallops which end in a pointed fashion toward one end, and are open toward the other. I looks like it could fit within a fuel line or part of the injector assembly. My son vaguely remembers the same part on the other injector apparatus and he thinks that it was sitting within the fuel stream at or near the junction between the fuel line from the injection pump and the injector holder assembly. My impression is that it somehow directs the fuel stream into 2 or 4 almost separate streams. I cannot find any part like it in the service or owners manual, and no one whom I've asked can identify it. It seems, however, that it's a bona fide part of the injection system and probably important. Attached to this note are 2 photos - the first shows the injector lines from the pump and their junctions with the nozzle holder assemblies before restoration (I think that the part came from somewhere near this junction). The second photo shows the part itself, as best as I can photograph it. I'm sorry that there is no scale, but the overall dimensions are as above.
I am located in California about 200 miles from the tractor, so I cannot readily respond to additional questions, but I can ask my son to do so. If you can identify this part and tell me where it is supposed to be located, I would be everlastingly grateful.
Thanks for any information.
