Read articles →This is a hands-on injection pump diagnostic on a 1970s Kubota L260, not a walkaround or overview. The owner pulls injectors, finds TDC manually without a working timing window, removes and times the Bosch-style pump to spec (20 degrees before TDC using the spill-port method), checks the overflow valve pressure, and explains the rack, shutdown rod, and governor oil maintenance. Best for owners troubleshooting white smoke, power loss, or injection timing on this specific pump.
