This is a new, genuine Kubota injection pump assembly, part number 1G548-51012. Kubota’s parts description is ASSY PUMP INJECTION, and it is the current number for the older 1G548-51010. Kubota engine dealers list it for the V3300, the 3.3 liter four-cylinder in Kubota’s V3 Series. It is a mechanical injection pump, not a common-rail supply pump.

Do not order it by engine model alone. Kubota’s own parts lists show other pumps on other V3300 builds: 1C010-51010 on the naturally aspirated V3300-E2B, and 1K012-51012 on the turbocharged V3300-T-E2B and V3600-T-E3B and on later M8200 and M9000 tractors. This 1G548 pump is a separate number, so the safe match is the number on your old pump, 1G548-51010 or 1G548-51012. A worn pump shows up as hard starting, low power, uneven running or fuel in the oil. Air in the fuel, a plugged filter and tired injectors cause the same complaints, so test before you replace it.

Specifications

Fits / Applications

• Kubota V3300 diesel engines (builds that call for pump 1G548-51010 or 1G548-51012)
• Direct replacement for Kubota injection pump 1G548-51010
• Other V3300 and V3600 builds take other Kubota pumps, 1C010-51010 or 1K012-51012, so order by the number on your old pump

Keep dirt out of the open fuel ports, fit new sealing washers on the fuel connections and bleed the fuel system before the first start. Check injection timing against the Kubota workshop manual for your engine build, then check the injection lines and the return line for leaks.

Frequently Asked Questions

What does the 1G548-51012 replace?

It is Kubota’s current number for injection pump 1G548-51010. If your old pump carries either number, this is the part.

Will it fit my Kubota V3300?

Only if your engine build calls for it. Kubota’s parts lists show 1C010-51010 on the naturally aspirated V3300-E2B and 1K012-51012 on the V3300-T-E2B, so call 530-668-0818 with your engine serial number and the number on your old pump.

Is this the injection pump for a Kubota M8200 or M9000 tractor?

No. Kubota’s tractor parts catalog lists 1C010-51010 and 1K012-51012 for those tractors, split by engine serial number, and it does not carry 1G548-51012.

Is it new or remanufactured?
