.about rebuilding a diesel injector pump ? Providing one has the special tools and 'instruction' manualis there any real reason a 'backyard bodger' couldn't rebuilt a pump ?? this came up on the 'other' orange site...so 'Kubota' pump, though NOBODY will post picture of what's inside. I just can't believe it's a 'can't be done' thing......

None that I'm aware of as long as you exercise clinical levels of cleanliness & anal-retentive attention to detail, I've rebuilt several Bosch VE pumps and never had a problem. As you say, as long as you have the tools & a good "play by play" instructional you should be fine. Points of note being that a lot of the internal parts are quite brittle (Governor cradle & plunger to name 2 on the Bosch) so care in handling to not crack them is needed, and there can be a LOT of tiny shims involved that need to go back in their rightful home. Also calibrating without a dyno rig is more a case of counting turns & putting things back exactly how you found them & 100% have a means of blocking the intake effectively for first start up just in case things go south... Don't have any experience of Roosa/CAV or others but can't imagine them being much easier or harder than the Borsch. Inline pumps probably less fiddly to do but more of the same really (clean clean clean, don't break the brittle bits).

I don’t know but I would presume the tool and testing equipment isn’t cheap. ------------- It's the color tractor my grandpa had! |

well NOTHING is "HARD" if you got all the right tools... How are you going to guarantee you got the same FLOW out of each piston ??? You need a FLOW BENCH..... thats a special tool ??? ............... I guess SOME injection pumps are pretty basic ... CAV ? ------------- Like them all, but love the "B"s. |

Kubota pumps I have worked on were for the old 2 cyls, cartridge pump, be careful removing, the gasket(thickness) is the timing adjustment...  ------------- Source: Babylon Bee. Sponsored by BRAWNDO, its got what you need! |
