Team, Seeking advice on an injector pump for a Kubota D722-EB diesel engine. Engine has 2,200 hours on it. Was smoking horribly when I traded into it/for it. I am hoping it is injectors or pump. Having injectors rebuilt. The pump comes with a bigger price tag for rebuild: $400-$650 depending on what it looks like once they are into it. Or, I can buy a brand new pump for $600. Any insight as to what the pump would be like to try and rebuild at home? Do-able or Nightmare? I'd rate myself an 8 on a 1-10 scale as a mechanic (maybe a 9 with enough Anheuser-Busch products in me). I'm the World's Best at takin' apart. It's the puttin' back together that I f up on quite a bit. As always - huge thanks for any information shared.
