Komatsu PC200 Fuel Filter 600-311-8321

Fitment and Service Notes

The fuel filter is the cheapest insurance on a diesel excavator. On the SAA6D107E-powered PC200-8, dirt and water that reach the injection pump and injectors can cost more than the machine's entire filter bill for a year — which is why Komatsu machines run a pre-filter/water separator element in front of the main fuel filter, and why the main element gets changed on schedule rather than on symptoms. Fuel-filter numbers vary with engine spec and market, so the two things that keep a PC200-8 owner out of trouble are the number stamped on the old filter and the machine serial; we confirm both before anything ships.

600-311-8321 appears on the same dealer service list as the PC200-8 hydraulic oil filter 207-60-71181, return filter 20Y-60-41130 and air filter 600-185-4100 — the set that a -8 series service interval orders together, with a separate pre-filter/water separator element on the same list. That makes this page the final piece of the Komatsu PC200-8 filter guide set: hydraulic filter 207-60-71181, return filter 20Y-60-41130, suction strainer 20Y-60-31140, air filter 600-185-4100 and now the main fuel filter 600-311-8321.
