Fitment and Service Notes
The suction strainer is the part of the PC200-8 hydraulic service that gets skipped most often, and it is the one that protects the pump. It sits on the suction side of the hydraulic tank — the mesh catches the debris that would otherwise go straight through the hydraulic oil filter and into the main pump. On the -8 series, Komatsu schedules the hydraulic oil filter element at the 1,000-hour PM and the return filter and suction strainer at the hydraulic oil change; the exact service points are in the PM table for your serial number. Skipping the strainer to save a few dollars on a $1,500–3,000 hydraulic pump is the wrong trade.
Ordering by machine model instead of part number is the most common source of wrong hydraulic parts on Komatsu excavators. The 20Y-60-31140 strainer is listed for the PC200-8, PC300-7 and PC300-8 (checked against live listings, August 2026) — it is not a universal Komatsu strainer, so read any number stamped on the old unit and send it with your serial number. We confirm the match before anything ships.
See our Komatsu PC200-8 filter guide for the complete service set — hydraulic oil filter 207-60-71181, return filter 20Y-60-41130, suction strainer 20Y-60-31140 and air filter 600-185-4100 — with OEM numbers, fitment notes and service points. The PC200-8 is the highest-volume excavator on the used market across Africa, the Middle East and Latin America, and this filter set is the one every service interval orders.
