Hi, I found that I have some contamination of my rotary valve oil by the coolant in my 582 grey head.
My two stroke oil is clear red color and my oil reservoir increases the level and it turns pink in color because the coollant.

I know that the problem are the seals at the pump shaft, I have the full gasket set but I want to know how to change this seals or if the shaft can be removed?
I removed from the valve side the clip ring retainer but the shaft don´t slide out
Is any internal retainer ring or the complete shaft with gear can be pulled from the rotary disc side?
