New Holland L-553 Kubota V1902B SN90365 Fuel Injection Pump

[jmcnicol]

No fuel coming from top of forth fuel injection pump port. Can't obtain parts or a complete fuel injection pump from either New Holland or Kubota. Not comfortable ordering from ebay type options. Any ideas or do I have a 2 ton solid waste problem? Thanks for any viable help.

Sounds like you need to get your injector pump serviced. If one is not giving any fuel, its out of adjustment and only a shop can re-adjust it.
I'm sure its not what you want to hear, but they are all linked with a rack, they are all adjusted together, if flow is non existant at one nozzle there is a problem.

Oops! Neglected to mention that I am some 250 miles from the nearest New Holland service and repair shop, lost the one 80 miles away years ago so if I can't fix it myself I'm, you know, ...out of luck. That's is why I was hoping I could do it myself. Just drop in a new injection pump or replace a broken part. This thing didn't slowly die it just gave up the ghost one day in early winter. Thanks Tazza

I have seen the plungers stick in the up position, not in this particular pump, but in similar pumps. If you feel comfortable in removing the pump you can tell if one of the plugers is stuck. All the rollers should be at the same height. Unless there is damage you may be able to free it up if not its time to send it to a pump shop.

Mike10 I'm leaving town this afternoon but I'll give your suggestion a try when I get back in a week or so. Thanks for the lead.
