Hi all,
I bought a used machine and needed to do a lot of work on it to get it to a good state. It's a bobcat t140 with a Kubota v2203 tier 2. I've replaced all the belts with pulleys and tensioners, all filters, all fluids, new lift pump, new shutoff solenoid, new injectors and injection pump. The machine starts up right away and runs no problem. Issue I'm running into is under load the machine puffs black smoke at that point and looses power right away, also after running the exhaust gets so hot that I need to shut machine down. After researching, I'm thinking the machine is running lean, so I went to check the timing on the fuel injection pump and it's way off. The second timing mark on the gear pushes fuel from #1 about an inch after both lines have passed, the service manual says that it should happen just when I hit that second line. I've tried removing shims and tested after each shim removed and I still cannot get the timing on it to set correctly. Currently only have 1 shim on the pump and it's still retarded an inch passed the mark and have no clue how to fix this. I believe that this is the issue with the machine running lean but I'm stumped on this. Any help would be great
