I am working on a bit of a dinosaur in todays standards, a 1988 koehring 6633 serial#110486 and I’m struggling to find usable numbers for the hydraulic filters. I have the original koehring books but can’t seem to track down anyone who can cross the numbers. There are two in tank filters, a pilot filter, and spin on filter. I have the smaller of the two in tank filters and the spin on but I’m coming up empty on the bigger in tank return and the pilot. I was hoping someone out there maybe had crossed these to a non-koehring number and could possibly help thanks
