8 Spool valve, part numer CEN00418. After we disassembled this valve and measured clearance's we found that the between thespool OD and valve body ID there was .002"/.007" clearance. That is a lot of wear and the customer had tried to install new seals but teh valve continued to leak. With the price of hydraulic fluid and the governments push for "Green Operations", a complete rebuild wasthe perfect solution. After we repaired the spools and valve body - Komatsu helped us get an OEM seal kit and out customer was back to making money.
