I have a Hitachi EX 60-1 the old 90s model it's a gray Market and I am rebuilding the travel motor because the seal went bad or something that leaked hydraulic fluid into the planetary gears but anyway I'm like 90% done I just need to figure out what this part is called and where I can get one I understand on the part catalog it says cap but I can't find it anywhere. Places that say they have it dont have a image for me to see if it's correct. I'll add a image of it its number 7 on the diagram
