Case 446 1986 Travel Control Valve overhaul

Hi, I have a leaky control valve and decided to replace all of the o rings in it. Took it appart and only found 2 of them, on the end where the linkage connect to. However I notice there is a wider groove on the cap/spring side. Looking at the diagram doesnt show anything. Is this the it's done or is there a part missing?

Here's some pics of my Valve, and the valve diagram. The diagram doesn't show any seals on the cap side, but how do I prevent oil to go in the cap?

One needs to look at the Diagram AND the parts listing, Especially the "REQ'D" column. where is shows that 4 of the O ring A7982 are required for each valve. With only 2 spools that makes for 2 Orings per spool, one at each end..

Later parts manuals for 4xxx tractors and the like do show 4 orings on the diagram as well.
