The fuel pump
on my Cummins-Onan MDKBM generator
isn't working. This is a Bosch/Zexel 16060 pump
on a Kubota 1505 engine
. I have carefully removed it and disassembled it and even found the corrosion
that might have stopped it working. But I have a problem, probably a big one. One that might cost me $1900 for a new injection pump
The image shows the many parts
already disassembled, and also shows 4 different shims marked 05, 12, 12, and 15. These are indeed very slightly different according to my micrometer. They are the part number 12 in the following image:
and are camshaft spacers. In the parts
list there is no mention of different shim thicknesses, there's just one part number.
I carefully noted which shim went into which barrel when I took it apart, writing it onto a Post-It pad and stuck it to main pump body. But I couldn't crack the seals
on the top part on board and don't have a vice; so I went ashore to a dock
where I could whack away and get those bolts off. But while doing so, my Post-It flew away and into the water
. I didn't notice that until too late...
I've reached out to Cummins-Onan, but doubt that they actually speak with mere customers and am not sanguine about my chances at getting an answer from them. I've search through the internet
, but my Google-Foo isn't powerful enough to let me locate an answer.
But the Kubota 1505 is a popular engine
amongst sailing folk, so I though I'd give it a try here!
